Slack is a group messaging or team collaboration app that aims to simplify communication for businesses. Features include open discussions, private groups, and direct messaging, as well as deep contextual search and message archiving, and file sharing. Slack integrates with a number of other tools, such as MailChimp, Dropbox, and Google Drive. The product is free to use, and also has paid plans with more features and greater controls. The company has raised $340M in funding and boasts 800k users.On the Slack Line: a Fun and Balanced Communications ToolOur department is among a handful that uses Slack as their primary work messaging tool (the organization default is Microsoft Teams). Slack is being used to support direct messaging and group chats between on-premises and remote employees, as well as service providers and vendors. It provides a system-agnostic communications workspace that can easily be ramified into various private and public channels as changing needs demand.,Slack is a solid chat tool that works across a variety of platforms, with a very low barrier for entry: new users can be invited via email, and can use web-based, desktop, or mobile versions of the application. Slack has really captured the zeitgeist of digital culture, including strong support for customizing look and feel (including custom emojis), and a plethora of integrations with popular web-based tools, including Pivotal Tracker and GitHub on the productive side, and Giphy.com on the fun side. Slack continues to refine and improve their product, with new features being rolled out just about every month. Slack offers a great value in their free version of the app, with most of the tool's functionality available for no cost.,While their focus on continuous product improvement is admirable, the pace of change sometimes introduces bugs to existing features. Some workspace administrative options require logging in to the workspace website -- it would be great to be able to manage all configuration directly from the desktop app. Allow me to be petty for a moment: Why can't we have bigger emojis?,10,Slack has allowed us to effectively collaborate with a wide range of collaborators, especially outside vendors, contractors, and service providers. Its integrated document sharing and videoconferencing features make it a powerful collaboration tool. Until recently, we utilized the free version of Slack, but this version does not support long-term storage of conversations and shared documents. However, as an EDU customer, it was surprisingly painless to move to a premium paid account. Slack definitely carries its corporate culture of "fun productivity" with it -- sometimes, the utility of its robust chat feature set can be offset by its ability to distract end-users with silly reaction emojis and meme threads..but this is a risk with any communications tool with a modern feature set.,Skype for Business (formerly Lync),10,Pivotal Tracker, GitHub, Atlassian Confluence(Probably) The best chat tool for tech companiesOur entire company is on Slack, which is great since we have employees located in different countries. I particularly like the sense of transparency it gives to our organization: We have a lot of different channels for business areas (marketing, engineering, etc) but they're all open for other employees to join and see what's being discussed.,Categorize discussions by channels. Fast, powerful mobile app. Almost all-in-one communication tool (chat and audio/video). Integrations with Google Drive, Trello, etc.,Ability to share my screen on the web version. For big organizations, (probably +150-200 employees) it might add too much noise if not managed correctly.,9,Project management: It helps managers get in-sync with individual employees. Makes onboarding easier for new employees since they get to see what every team is working on. Team announcements are easier to do and react to.,HipChat,10Slack- a great tool and embraced by our group!Our department of IT project development uses Slack for communication between team members. This enables us to work remotely and more efficiently, and also allows us to target communication easily to individuals as well as custom groups. The whole organization has not started using this product at this time. But every member of the IT project development team is actively using this to discuss and share project issues and concerns as well as for department announcements, and various social uses- such as lunch planning, sharing various interests and items on the internet.,Sending notifications when messages are sent to you. Ease of user interface. Ability to add and communicate to people outside of your organization. Ability to share images and documents.,We are happy with all the funcationality in Slack.,8,I believe this has increased productivity amongst the team in that we can get immediate responses to issues and questions, allowing us to have a better continuous flow of work Having an easy to use tool like this speeds up on boarding, as new team members can easily learn. They also will have access to all existing resources within the tool We have been able to customize communication groups to include those appropriate, eliminating unnecessary noise regarding areas not relevant to particular team members.,Skype for Business (formerly Lync),ZenHub, Microsoft Visio, Microsoft Office 2016, WorkfrontSlack is anything but whackMy company uses Slack for communication purposes on a daily basis. We can send files, Pictures, Giphys and much more! It has a way to set reminders for our group channels so certain tasks are able to be set for daily reminders. It helps us communicate and avoid any gaps in our daily tasking.,To send photos, all you have to do is click, drag, and drop into the chat box. Very easy! I like how easy it is to create as many conversations as you'd like with 1 or more individuals. There are groups that we have that many agents can communicate big changes in an instant! By just the click of a button.,I'd like to see a little more customization as far as my view of slack goes. Such as skins or color changes. It would be nice to be able to have a chat board where you can see several conversations at once instead of toggling back and forth from one side bar and only being able to be in one chat at a time. There are certain times when someone will leave the company and they have a Channel open that they created. Others can't close it because the individual would need to close it however they are not around any longer. It would be nice if we could remove those more easily.,10,I am not aware of this because I didn't have part in ordering or purchasing the software. However, as a user, I'd say it is VERY worth any amount of money to have better communication between your teammates!,,10,monday.com, Zendesk, UnbounceSlack, good if you need to chatWe use Slack throughout our company to communicate between and within teams. It's used for both projects and regular day to day communication that would otherwise be done via email. Slack allows our employees to share documents and participate in group discussions, as well as communicate around specific events (managed through individual channels).,Instant communication with the ability to snooze notifications Allows you to share documents and refer to them at a later time Allows you to set your status so that you aren't constantly interrupted with messages if you are working closely on a project,Needs the ability to select specific gifs, the interface to send gifs is clunky When additional channels are created, it's hard for participants to keep up on the channels that include info for them, basically requires that they are "at mentioned" or they get ignored It would be nice to be able to hide channels you don't care about,7,Increase immediate communication between departments Helped us to streamline certain processes Helped us to maintain documentation on discussions, save time.,Olark,7Lightning Fast CommunicatingI love using Slack. It is by far the best communication system out on the market for businesses to use. I have been using Slack for over a year and I love how easy it is to create group chats and individual chats. I am able to connect with fellow employees with ease. It is super easy to share files and links with co-workers. Another cool thing is if another company has Slack, you can connect with them which is super nice because you can have a live chat with any user of Slack. Slack is my go-to for communicating with co-workers because it allows me to get almost instant answers.,Easy to communicate with fellow co-workers Ability to communicate with other companies that have Slack Slack downtime is very rare, if any.,It gets very expensive if you have a huge company Unable to unread messages to remind me to read again,10,Quick communication with co-workers Easy to share documents Ability to communicate with other companies Negative: Unable to unread messages so this increases the chances of me forgetting to do something.,Trello,10,Trello, QuickBooks Online, Google Drive, Google DomainsIf you want a great way to chat than pick up the Slack.The way we used Slack was to communicate within the training team, the other thing was to send simple files and photos. For example, because we would work offsite quite a bit we would need to take pictures of the restaurant, using Slack allowed us to send pictures quickly to the director of training and development. It was also easier to use this tool to communicate in the office when we were busy and didn't want to interrupt anyone. We had a fairly enclosed space so this allowed us to talk not only in private within our team.,Easy to send files and images. Easy to download the app and use for in-home use. We used it both on PC and on our phones through the app. Requires no training or additional software.,Slack had a tendency to freeze but we couldn't figure out why.,10,It has allowed us to make rapid changes in the restaurants especially if/when there was a problem. This in fact helped in a situation where one of the restaurants was flooded and we needed to send pictures quickly to several managers to get it resolved.,10Keep your organization connected with SlackSlack is being used across the whole SAP organization. It allows us to communicate and share files.,Slack allows for real-time communication, both at the organizational level and personal level, thanks to the channels you can create. The quality of voice calls and screen sharing is high. The instant messaging service has many useful and unique features. I like a lot that you can share code snippets, which is great for software developers.,The Slack learning curve is relatively high, especially for non-tech people, learning to use Slack might take some time. There are not many themes, and the existing ones are mainly a change in the color palette.,9,Slack minimizes the time required to communicate or get in contact with someone. As calls and messages are free, the cost is highly reduced for employees.,Skype for Business (formerly Lync), Skype and Adobe Connect,8,Asana, IntelliJ IDEA,Search engine Sharing media Making calls,Change themes General configuration,Yes, but I don't use it,8Great for improving communication!We use Slack to communicate with our clients in a platform that's easy to use. Oftentimes, communication between our agency and our clients can get lost in a mess of emails, texts, and call. By keeping most communication in Slack, we're able to streamline the workflow while having a written record of most communication. Also, we integrate Slack with a lot of our outside programs like MailChimp and Jotform, that allows us to see a timeline and effect of our marketing efforts.,Integration of 3rd party software - We can connect Mailchimp, jotform, BigCommerce, and other programs into the Slack newsfeed, which shows a basic flow of company updates that allows people to see important information like new leads coming in and marketing emails going out. Plenty of options - Slack features the threads of conversation, personal messages, company-wide chat, as well as VoIP and file-sharing capabilities. This makes it easy for everyone to use or communicate in the way in which they prefer. Omnisearch - The search bar in a slack account allows you to search for everything: your personal messages, main news feed, shared files, etc. It is very convenient when you need to find all the info about a particular topic or find a file (especially if you can't remember who sent the file or how it was shared.) Easy to keep track of multiple accounts - With multiple clients, we need to switch between multiple "workspaces" and Slack makes it easy to change between accounts.,The maximum temporary account renewal length is 14 days. It would be more convenient if it were a month/quarter/year, etc. When signed-out, Slack loses the redirect cookie, so if I click a link to a workspace in an email, I have to sign in, then re-click the link. It would be better if it just redirected automatically.,9,Keeps a record of requests and discussion in case of a dispute later on. This protects both us (as an agency) and the client. Streamlines the flow of a project so that we can make sure it gets the necessary approvals before moving forward. Makes it easier to search through communication to find lost messages or files weeks or months later.,Asana, Wrike and Workplace by Facebook,9,Asana, eClincher, Google Ads (formerly AdWords)Second go around with Slack not so good, why do we use this thing?Well we are on our second go around with Slack. We implemented it many years ago but it fizzled out. About a year ago we resurrected the product. I just don't know about how it fits in to our enterprise. There are some areas that use it a lot to keep track of say network or SaaS issues which are timely in nature. However there are others who just don't need to use it for much. I would say there is about 20% of our division that uses it actively. Unfortunately, much of the other 80% sees it as an annoyance. Furthermore, some of the 20% that uses it seems to think that they need to communicate what they say on Slack in a duplicate manner via email or vice versa.,It duplicates other services that we already have really well. For example, Yammer, our LMS, and other general communications tools. I like that you can add pictures. It is sort of retro, like ICQ.,Totally annoying and disruptive to getting anything done. Seems to go down the most out of all our cloud services, and we got a bunch of them. The UI is just bad. Not intuitive. Not a good value.,3,All Slack is happens to be another communications tool. There are lots of them out there. This one for some reason has gained traction. It is mostly a waste of time because it duplicates other tools and also duplicates communication. Don't send me the same message via email, slack, CRM, and a web page. Just stupid. We don't speak four different languages at work, face to face, for the hell of it. Why do we do this in the way we communicate digitally? Slack tends to be unavailable or "goes down" quite a bit. Not good for a tool for which folks relay on to get the important news out.,Microsoft Yammer,2,Sakai, Box, AtomSlack is the ideal tool for team collaboration!Slack is very important for communication in our team. It helps us stay on track on most important conversations that happen in our group. We use it to share information and the most important updates in our field of work, also to synchronize activities and tasks. In summary, it is a very useful tool that we use everyday.,Very intuitive and easy to use. Nice user interface with a simple and clean design. Possibility of integration with other apps.,It is not possible to add people to a Direct Message conversation a posteriori. The desktop app could be made more efficient. It is not possible to merge different channels into a single one, could be a useful feature.,9,Very useful and powerful collaboration tool helps for effective team communication. Allows questions to be answered quickly rather than hitting a bottleneck. It allows organizations to thrive in a remote world, saving time and costs.,Skype,9,Authy, GoToMeeting, Skype for Business (formerly Lync)Slack increases work productivityWe use Slack to communicate with team members that work remotely or are in different locations to share ideas on how to achieve our goals or help each other on tasks. We are able to collaborate on projects and finish them on the stipulated time which in return increases work productivity.,It has an intutive user interface which is user- friendly to all users. It is easy to use. It is easy to set up and configure. Highly customizable. It is easy to upload links and send them to other team members.,Too many alerts and I lose control of them. The application may at times crash.,10,Slack has increased work productivity It has enabled us to finish projects in an timely manner It has helped us communicate efficiently,10,10The communication tool every modern team needs in their arsenal to improve clarity and build their team spiritSlack plays a crucial part in how all of our organization and its departments communicate with one another. Slack helps us stay on track on most important conversations that happen between and within teams, and the wealth of integrations make it our central hub for notifications. Also, with 1/3 of the team being remote, it's one of our primary tools of keeping in touch with people who we don't see every day at the office.,Brilliant user interface (sending messages, creating groups, finding relevant information is easy). Improves communication and is super fun to use: you can express your feelings in GIFs or reward team members with imaginary tacos - there are so many fun ways to use the app! Wealth of integrations with other tools (meaning we can create tasks in seconds in tools like Asana or even monitor all relevant notifications coming through for leads or costomers from HubSpot).,Having a lot of notifications can feel overwhelming sometimes (but Slack allows you to tailor what you receive notifications for). It would be cool for video calls to take up less bandwidth and be of better quality. Search functionality focuses on relevance, not date but has improved A LOT in the last year.,10,We have improved how we communicate across teams and timezones Team members develop stronger relationships as Slack allows them to show their personality and be a bit more fun Faster responses on live chats on our website with the help of notifications in Slack,10,8,Skype and TeamViewer,WordPress, Dropbox, SquarespaceSlack revolutionized my lifeSlack has revolutionized the way we communicate and share updates. I first came across slack when joining a new research group, where the lead is split between ours and another academic institution. Email is a bit difficult to keep track of when you're as senior as he is, so I was told to use Slack to keep him up to date with things and ask any questions. I have since used it for my project, and it is by far one of the easiest ways to manage and communicate with the rest of the team on a day to day basis. I can manage, read, reply to and create my own messages at my leisure, as I could with emails, but without the faff.,Simple design and super easy to use. Lots of customizations and integrations of other apps (like calendars). Having a standalone app makes it much more appealing to the younger generation who would prefer to be able to access it on the move too.,I had a few issues in trying to get the channels set up properly, but less of an issue and more of a learning experience.,10,It has made it much easier to communicate with people who are remote to my office, but part of the same team, allowing us to collaborate effectively. It's free, so any benefit has already outweighed the input!,10,10,The best team communication and collaboration app availableOur entire organization uses Slack to communicate on projects, to build and support company culture, and to collaborate with other 3rd party vendors when we are working together to create integrated systems and solutions. There are a lot of other software programs we could use for different collaborative tasks but Slack allows us to do all of them in one place (e.g. standard communication, file sharing, restricted channels, etc.).,Slack allows you to pin specific content so it is easy to find within a channel even if it was posted months or even years ago. Slack allows each user to deeply customize how they use the program. So everyone can be on the same company account but set their own navigation and aesthetic preferences. Slack is very integrative. You can set up automatic notifications in specific channels based on triggers occurring in your CRM or marketing tools.,You can create channels and bring people into a DM, but unfortunately, you can't add people to an ongoing DM. Sometimes we have two channels serving a similar purpose and we need to archive one of them to be more efficient. It would be nice to be able to merge the two channels or do something similar to preserve important content from both places. GIFs are often too big for Slack to display so they appear as a link and have to be expanded to view the content. It would be nice if Slack could handle larger images.,10,Slack has helped us be more efficient and finish projects quickly. Slack allows us to grow the company culture and keep valuable employees. Slack allows us to respond instantly in emergency dev or client need situations.,9,9,Trello and Hive,Trello, Zenefits, Grow.comAn Awesome Application for Enabling CollaborationIt was a nightmare before when coordinating software delivery teams within the organization. However, after we adopted Slack our software delivery teams got a very reliable collaboration tool. With this software, different teams can work together across geographic boundaries without limitations. It has also been integrated into our workflow and development pipeline to ensure smooth flow of communication. Project management teams remain on the same page all through the period of project execution courtesy of Slack.,It allows team collaboration It allows remote collaboration Slack allows communication with external parties,Sometimes it brings too many notifications which are annoying The use of emojis and GIFs makes it informal,10,It has made collaboration in the organization to be significantly easier It is easier to communicate with external teams,10,10,Skype for Business (formerly Lync),Mailchimp, Workfront, Google Ad ManagerSlack - Awesome at enabling collaborationSlack has been used across our software delivery teams as the go to collaboration tool for a number of months now.

It is a very useful tool as it brings the whole team on a single base while talking about the project modules. The Slack channels help us to easily formulate the idea and discuss that topic. Highlighting important notes is also a good feature which lets us control the content and use it when necessary. Also, the admin has the rights to give access for speaking and listening individually which avoids creating a mess in the discussion, which I personally like. Apart from that, we are using Slack at different levels, like we have a channel for the module on which my team works. Also, we have a general project-based channel where we discuss the updates and so on in the hierarchy. It is being used by every single person in my company.,Channel creation Highlights Control over discussion Dark theme,Not easy for beginners.

It is used across the whole organization. Through Slack, we form a small group while working on a project, we do this for quick and easy passing of information.,Easy to use. Nice UI and UX.

We have channels for different departments/teams, as well as inter-departmental channels, and heavily use the direct messages. It is used for discussions, and for support, including sharing screenshots, etc. It is also needed for looking back at older conversations, and to reference tasks/decisions from the past.,Chat history. You can search the history of chat channels or direct messages, even if you joined at a later date. Integrations. Many supported apps, such as Google Drive, Jira, etc. Use anywhere. Can run as a program on the computer, or just in a browser, or on mobile devices.,Left Navigation Pane. The left nav is not able to be resized, so I can't actually see the whole channel or person name. Really annoying when the phone extensions are added to the end of the names, but they are hidden by the left nav. Conversation List Sorting. The conversations, specifically the direct messages, auto-sort, and auto disappear based on what Slack thinks it should do. I constantly have people/conversations missing from the left nav and have to search for them manually. More-Actions Bar. The "more actions" bar that shows up at the right of the conversation view frequently gets in the way of actually clicking/highlighting text in that conversation. It needs to be set to not be on top of the conversation that is being hovered over.,8,Positive: The ability to maintain a constant point of contact to anyone in the organization. Positive: The ability to maintain an archive of company communications. Positive: The ability to have "guest" users that don't actually use a paid license.,HipChat,Microsoft Office 365, G Suite, GoToMeetingThe right tool for the jobWe use Slack throughout the company as well as a communication tool within the incubator program our company is in. It has been an excellent way for everyone to communicate, share ideas and to stay on top of tasks and projects that are ongoing. I also use Slack as part of another organization that I collaborate with and it has been instrumental in everyone staying informed on the day to day activities that are taking place.,Being able to create channels is a great strength. It allows team members to be grouped and in-the-know where necessary, while not needing to be notified when it's not applicable. The "Do not disturb" feature is a simple, but important one to have. It's a great way to be able to turn off and tune out of work during personal time. Sharing files and links is super simple. Being able to go back and reference them and easily find them makes it instrumental as a communication and collaboration tool.,When it comes to direct messaging, I wish that the most recent messages would automatically be listed in the section below the Channels section. If you want to see your most recent direct messages you have to swipe sideways when looking at the channels screen (on mobile) and then see your most recent messages. Just seems like an unnecessary extra step. While I love the "do not disturb" feature, I think Slack should make it clear that by default it turns on after a certain time. When downloading and using the app for the first time I couldn't figure out why I wasn't receiving notifications. It wasn't until I learned about Do Not Disturb that I realized I had to change my settings. It should be something that a new user is made aware of when first downloading and using the app. I don't know if everyone experiences this or not but it seems to me that the desktop app does not update as instantly as the mobile app (I use a Mac). It's not an issue of my internet speed as we have a perfectly fast connection, and besides, my iPhone is connected to the same network. The desktop app just seems to lag a little.,9,Better communication = time efficiency. Simple. The ability to separate groups into channels makes applicable work easier to handle and discuss. This also increases efficiency among those involved. Being able to collaborate with others in our incubator has provided us with other ideas and tools that we weren't aware of. In turn, we have made purchasing decisions that have benefited our company greatly.,,Gusto, WebTextToolSlack ReviewWe use it for internal communication with history and file sharing.,Internal chatting.

Our department is among a handful that uses Slack as their primary work messaging tool (the organization default is Microsoft Teams). Slack is being used to support direct messaging and group chats between on-premises and remote employees, as well as service providers and vendors. It provides a system-agnostic communications workspace that can easily be ramified into various private and public channels as changing needs demand.
  • Slack is a solid chat tool that works across a variety of platforms, with a very low barrier for entry: new users can be invited via email, and can use web-based, desktop, or mobile versions of the application.
  • Slack has really captured the zeitgeist of digital culture, including strong support for customizing look and feel (including custom emojis), and a plethora of integrations with popular web-based tools, including Pivotal Tracker and GitHub on the productive side, and Giphy.com on the fun side.
  • Slack continues to refine and improve their product, with new features being rolled out just about every month.
  • Slack offers a great value in their free version of the app, with most of the tool's functionality available for no cost.
  • While their focus on continuous product improvement is admirable, the pace of change sometimes introduces bugs to existing features.
  • Some workspace administrative options require logging in to the workspace website -- it would be great to be able to manage all configuration directly from the desktop app.
  • Allow me to be petty for a moment: Why can't we have bigger emojis?
Slack is great when you have a working group that is spread out over various locations; beyond facilitating productive chat sessions -- as well as video conferencing and screen sharing (depending on your pricing tier) -- Slack's fun features can really help to build team camaraderie.

Slack may not be a great fit for working groups that prefer face-to-face communications, or those teams that are already well-acclimated to another group chat tool.

Our entire company is on Slack, which is great since we have employees located in different countries. I particularly like the sense of transparency it gives to our organization: We have a lot of different channels for business areas (marketing, engineering, etc) but they're all open for other employees to join and see what's being discussed.
  • Categorize discussions by channels.
  • Fast, powerful mobile app.
  • Almost all-in-one communication tool (chat and audio/video).
  • Integrations with Google Drive, Trello, etc.
  • Ability to share my screen on the web version.
  • For big organizations, (probably +150-200 employees) it might add too much noise if not managed correctly.
Scenarios where Slack is well suited:
  • Distributed teams and/or companies with multiple offices.
  • Startups: Helps new employees get a quick view of the "bigger picture" -- everything that's happening inside the organization.
  • Teams that need real-time communication to run their operations (eg. customer support, engineering).

Scenarios where Slack is less appropriate:
  • Large organizations with several hundred employees if not managed correctly -- it can add too much noise/distractions.

Our department of IT project development uses Slack for communication between team members. This enables us to work remotely and more efficiently, and also allows us to target communication easily to individuals as well as custom groups. The whole organization has not started using this product at this time. But every member of the IT project development team is actively using this to discuss and share project issues and concerns as well as for department announcements, and various social uses- such as lunch planning, sharing various interests and items on the internet.
  • Sending notifications when messages are sent to you.
  • Ease of user interface.
  • Ability to add and communicate to people outside of your organization.
  • Ability to share images and documents.
  • We are happy with all the funcationality in Slack.
It is especially valuable in helping with communcation between remote team members. The ability to call and share screens is really helpful, and has become our go to method to communicate, eliminating the need for skype and our various conference call systems available in our company. Using Slack for calls and meetings is now extensive within our group, and is done many, many times per day. it is easy to add people and to share and give sharing capabilities to other team members.

My company uses Slack for communication purposes on a daily basis. We can send files, Pictures, Giphys and much more! It has a way to set reminders for our group channels so certain tasks are able to be set for daily reminders. It helps us communicate and avoid any gaps in our daily tasking.
  • To send photos, all you have to do is click, drag, and drop into the chat box. Very easy!
  • I like how easy it is to create as many conversations as you'd like with 1 or more individuals.
  • There are groups that we have that many agents can communicate big changes in an instant! By just the click of a button.
  • I'd like to see a little more customization as far as my view of slack goes. Such as skins or color changes.
  • It would be nice to be able to have a chat board where you can see several conversations at once instead of toggling back and forth from one side bar and only being able to be in one chat at a time.
  • There are certain times when someone will leave the company and they have a Channel open that they created. Others can't close it because the individual would need to close it however they are not around any longer. It would be nice if we could remove those more easily.
Slack is suited for a small growing business that needs several channels of communication between departments. It is nice also because Slack has a phone app, so you don't even need to be at your computer to use it. We can easily get a message at any time when we are available on the app. Very convenient for those of us who are more mobile!

We use Slack throughout our company to communicate between and within teams. It's used for both projects and regular day to day communication that would otherwise be done via email. Slack allows our employees to share documents and participate in group discussions, as well as communicate around specific events (managed through individual channels).
  • Instant communication with the ability to snooze notifications
  • Allows you to share documents and refer to them at a later time
  • Allows you to set your status so that you aren't constantly interrupted with messages if you are working closely on a project
  • Needs the ability to select specific gifs, the interface to send gifs is clunky
  • When additional channels are created, it's hard for participants to keep up on the channels that include info for them, basically requires that they are "at mentioned" or they get ignored
  • It would be nice to be able to hide channels you don't care about
Slack is a useful tool in instances where you need to get your entire company or team utilizing one method of communication outside of email. It's similar to other chat platforms but has a number of additional benefits like the ability for developers to share code back and forth. It might not be useful in instances where employees use it as a distraction.

I love using Slack. It is by far the best communication system out on the market for businesses to use. I have been using Slack for over a year and I love how easy it is to create group chats and individual chats. I am able to connect with fellow employees with ease. It is super easy to share files and links with co-workers. Another cool thing is if another company has Slack, you can connect with them which is super nice because you can have a live chat with any user of Slack. Slack is my go-to for communicating with co-workers because it allows me to get almost instant answers.
  • Easy to communicate with fellow co-workers
  • Ability to communicate with other companies that have Slack
  • Slack downtime is very rare, if any.
  • It gets very expensive if you have a huge company
  • Unable to unread messages to remind me to read again
Slack has been built to work on your web browser, as an app on your computer, and an app on your smartphone. Slack has spent the money to make sure that their program rarely has downtime. I love how easy it is to communicate with my co-workers on Slack. It is easier than sending an email to a co-worker. Slacks improves efficiency in the company because employees are able to communicate with each other with ease especially if the company has multiple locations across the country or across the world. Slack will even let you know what time it is for the recipient you are sending the message to which is great if you have overseas employees.

The way we used Slack was to communicate within the training team, the other thing was to send simple files and photos. For example, because we would work offsite quite a bit we would need to take pictures of the restaurant, using Slack allowed us to send pictures quickly to the director of training and development. It was also easier to use this tool to communicate in the office when we were busy and didn't want to interrupt anyone. We had a fairly enclosed space so this allowed us to talk not only in private within our team.
  • Easy to send files and images.
  • Easy to download the app and use for in-home use. We used it both on PC and on our phones through the app.
  • Requires no training or additional software.
  • Slack had a tendency to freeze but we couldn't figure out why.
I think the best use for the tool would be via the app especially if you travel a lot and you have a team (if you are a manager this is exceptionally important). But this app allows you to very easily communicate with anyone fast and efficiently. I think it's also a good way for a small company that doesn't have the room for a board room, you can easily handle small private meetings via Slack.

Slack is being used across the whole SAP organization. It allows us to communicate and share files.
  • Slack allows for real-time communication, both at the organizational level and personal level, thanks to the channels you can create.
  • The quality of voice calls and screen sharing is high.
  • The instant messaging service has many useful and unique features. I like a lot that you can share code snippets, which is great for software developers.
  • The Slack learning curve is relatively high, especially for non-tech people, learning to use Slack might take some time.
  • There are not many themes, and the existing ones are mainly a change in the color palette.
Slack is well suited for organizations which are geographically distributed among many cities/countries. For small groups or those that are physically located at the same place, it may not be the best way to go.
Also for organizations with multiple derpaments/divisions, the channels provide a natural solution to have both general communication and group-specific communication.

We use Slack to communicate with our clients in a platform that's easy to use. Oftentimes, communication between our agency and our clients can get lost in a mess of emails, texts, and call. By keeping most communication in Slack, we're able to streamline the workflow while having a written record of most communication. Also, we integrate Slack with a lot of our outside programs like MailChimp and Jotform, that allows us to see a timeline and effect of our marketing efforts.
  • Integration of 3rd party software - We can connect Mailchimp, jotform, BigCommerce, and other programs into the Slack newsfeed, which shows a basic flow of company updates that allows people to see important information like new leads coming in and marketing emails going out.
  • Plenty of options - Slack features the threads of conversation, personal messages, company-wide chat, as well as VoIP and file-sharing capabilities. This makes it easy for everyone to use or communicate in the way in which they prefer.
  • Omnisearch - The search bar in a slack account allows you to search for everything: your personal messages, main news feed, shared files, etc. It is very convenient when you need to find all the info about a particular topic or find a file (especially if you can't remember who sent the file or how it was shared.)
  • Easy to keep track of multiple accounts - With multiple clients, we need to switch between multiple "workspaces" and Slack makes it easy to change between accounts.
  • The maximum temporary account renewal length is 14 days. It would be more convenient if it were a month/quarter/year, etc.
  • When signed-out, Slack loses the redirect cookie, so if I click a link to a workspace in an email, I have to sign in, then re-click the link. It would be better if it just redirected automatically.
Slack is great for bigger companies or for teams that don't communicate well. Also, we've found it useful as an agency to communicate with our clients. Though Slack is mostly a glorified chatroom, keeping a record of conversations allows for us to go back an make sure we haven't missed anything or check the written record against claims that may say otherwise. Plus, it helps us communicate in ways that are more comfortable for people who don't communicate as readily.

Well we are on our second go around with Slack. We implemented it many years ago but it fizzled out. About a year ago we resurrected the product. I just don't know about how it fits in to our enterprise. There are some areas that use it a lot to keep track of say network or SaaS issues which are timely in nature. However there are others who just don't need to use it for much. I would say there is about 20% of our division that uses it actively. Unfortunately, much of the other 80% sees it as an annoyance. Furthermore, some of the 20% that uses it seems to think that they need to communicate what they say on Slack in a duplicate manner via email or vice versa.
  • It duplicates other services that we already have really well. For example, Yammer, our LMS, and other general communications tools.
  • I like that you can add pictures.
  • It is sort of retro, like ICQ.
  • Totally annoying and disruptive to getting anything done.
  • Seems to go down the most out of all our cloud services, and we got a bunch of them.
  • The UI is just bad. Not intuitive.
  • Not a good value.
Slack would be well suited if you had a development team in Mongolia and another one in France and they did not have to talk to each other a whole lot. Slack would be a good record of fact on what might be going on between the groups. It can keep track of things, almost like a log of human interactions.

Slack is very important for communication in our team. It helps us stay on track on most important conversations that happen in our group. We use it to share information and the most important updates in our field of work, also to synchronize activities and tasks. In summary, it is a very useful tool that we use everyday.
  • Very intuitive and easy to use.
  • Nice user interface with a simple and clean design.
  • Possibility of integration with other apps.
  • It is not possible to add people to a Direct Message conversation a posteriori.
  • The desktop app could be made more efficient.
  • It is not possible to merge different channels into a single one, could be a useful feature.
Slack is well suited for communication within an organization and it is ideal for not very large groups. It is not so suitable for reaching out someone in a more formal way or when large files need to be shared. For larger organizations with a more formal hierarchy, this tool might not be very useful to be utilized across the several layers of the hierarchy.

We use Slack to communicate with team members that work remotely or are in different locations to share ideas on how to achieve our goals or help each other on tasks. We are able to collaborate on projects and finish them on the stipulated time which in return increases work productivity.
  • It has an intutive user interface which is user- friendly to all users.
  • It is easy to use.
  • It is easy to set up and configure.
  • Highly customizable.
  • It is easy to upload links and send them to other team members.
  • Too many alerts and I lose control of them.
  • The application may at times crash.
It is well suited for small groups as you will have control of all notifications received. For larger groups, it might be difficult to control alerts received and you will be confused. It is perfect for short term projects as it would be easy to manage content.

Slack plays a crucial part in how all of our organization and its departments communicate with one another. Slack helps us stay on track on most important conversations that happen between and within teams, and the wealth of integrations make it our central hub for notifications. Also, with 1/3 of the team being remote, it's one of our primary tools of keeping in touch with people who we don't see every day at the office.
  • Brilliant user interface (sending messages, creating groups, finding relevant information is easy).
  • Improves communication and is super fun to use: you can express your feelings in GIFs or reward team members with imaginary tacos - there are so many fun ways to use the app!
  • Wealth of integrations with other tools (meaning we can create tasks in seconds in tools like Asana or even monitor all relevant notifications coming through for leads or costomers from HubSpot).
  • Having a lot of notifications can feel overwhelming sometimes (but Slack allows you to tailor what you receive notifications for).
  • It would be cool for video calls to take up less bandwidth and be of better quality.
  • Search functionality focuses on relevance, not date but has improved A LOT in the last year.
Slack is a brilliant communication tool for teams of all sizes and industries, but it's probably best suited for businesses that use a lot of digital tools, like B2B SaaS or e-commerce. Implementing Slack the right way and making sure the channels and workspaces don't become a mess is crucial for everyone to have a good time while using it.

Slack has revolutionized the way we communicate and share updates. I first came across slack when joining a new research group, where the lead is split between ours and another academic institution. Email is a bit difficult to keep track of when you're as senior as he is, so I was told to use Slack to keep him up to date with things and ask any questions.
I have since used it for my project, and it is by far one of the easiest ways to manage and communicate with the rest of the team on a day to day basis. I can manage, read, reply to and create my own messages at my leisure, as I could with emails, but without the faff.
  • Simple design and super easy to use.
  • Lots of customizations and integrations of other apps (like calendars).
  • Having a standalone app makes it much more appealing to the younger generation who would prefer to be able to access it on the move too.
  • I had a few issues in trying to get the channels set up properly, but less of an issue and more of a learning experience.
If you talk to people or manage people, and want to free up your time and theirs, use Slack. It is a fantastic communication tool and allows personal, individual, group or whole organization chat groups that can be separated into specific topics. There is a very generous message allowance on the free option, with more again on the paid ones, along with additional features. Big or small organizations, it's great.

Our entire organization uses Slack to communicate on projects, to build and support company culture, and to collaborate with other 3rd party vendors when we are working together to create integrated systems and solutions. There are a lot of other software programs we could use for different collaborative tasks but Slack allows us to do all of them in one place (e.g. standard communication, file sharing, restricted channels, etc.).
  • Slack allows you to pin specific content so it is easy to find within a channel even if it was posted months or even years ago.
  • Slack allows each user to deeply customize how they use the program. So everyone can be on the same company account but set their own navigation and aesthetic preferences.
  • Slack is very integrative. You can set up automatic notifications in specific channels based on triggers occurring in your CRM or marketing tools.
  • You can create channels and bring people into a DM, but unfortunately, you can't add people to an ongoing DM.
  • Sometimes we have two channels serving a similar purpose and we need to archive one of them to be more efficient. It would be nice to be able to merge the two channels or do something similar to preserve important content from both places.
  • GIFs are often too big for Slack to display so they appear as a link and have to be expanded to view the content. It would be nice if Slack could handle larger images.
Slack is great for smaller, short term projects. Channels can be set up quickly, topics set, and content loaded quickly. However, it struggles more with long-term projects where a lot of content needs to be managed and organized. Because channels and DMs scroll like a text message chain, it is not easy to manage sub-tasks within the channel like in a kanban board.

It was a nightmare before when coordinating software delivery teams within the organization. However, after we adopted Slack our software delivery teams got a very reliable collaboration tool. With this software, different teams can work together across geographic boundaries without limitations. It has also been integrated into our workflow and development pipeline to ensure smooth flow of communication. Project management teams remain on the same page all through the period of project execution courtesy of Slack.
  • It allows team collaboration
  • It allows remote collaboration
  • Slack allows communication with external parties
  • Sometimes it brings too many notifications which are annoying
  • The use of emojis and GIFs makes it informal

Slack has been used across our software delivery teams as the go to collaboration tool for a number of months now. It helps us work together across geographic boundaries and is integrated into our workflow and development pipeline. It means we can all be sure we are on the same page and also easily contactable.
  • Remote collaboration
  • Team Collaboration
  • Enable communication with external companies
  • Can come across as not a serious tool due to use of gifs emojis
  • Notifications can be annoying
  • Sometimes hard to be across all channels without explicitly being invited
Slack is really well suited for organisations with geographically dispersed teams who need to collaborate and communicate effectively. It is particularly well suited for collaboration amongst technical teams. It also works very well to enable communication with third parties such as vendors or suppliers.

What we have found does not work as well is collaboration with more business focussed teams, for some reason they don't take to it as well.

We use Slack with all of our management staff, and it has drastically cut email volumes which would often reach astronomical levels and not all of the relevant people would be informed of news or updates. This way, if you're interested or implicated in a department, you'll be on the slack channel and will instantly be informed!
  • Avoiding email communication and keeping internal communication concise and to the point
  • Making sure the relevant team members can have relevant discussions instead of ignoring length emails that seem pointless or overwhelming
  • Allowing you to snooze notifications so you don't have to receive work notifications outside of work (unlike WhatsApp or SMSs)
  • The snooze function often seems to kick in automatically which I personally don't want (I actually like to be always connected)
Slack is great for smaller companies, I wouldn't see it working for larger companies so well as you can't easily manage a whole team and the volume of messages would just be too much. Or perhaps you could use it on a departmental basis. We also use it for free so it's great for organizations with a tight budget!

Slack is a professional messaging tool used in our organization. It is a very useful tool as it brings the whole team on a single base while talking about the project modules. The Slack channels help us to easily formulate the idea and discuss that topic. Highlighting important notes is also a good feature which lets us control the content and use it when necessary. Also, the admin has the rights to give access for speaking and listening individually which avoids creating a mess in the discussion, which I personally like. Apart from that, we are using Slack at different levels, like we have a channel for the module on which my team works. Also, we have a general project-based channel where we discuss the updates and so on in the hierarchy. It is being used by every single person in my company.
  • Channel creation
  • Highlights
  • Control over discussion
  • Dark theme
  • Not easy for beginners.
  • Mobile app requires some improvement
It is very well suited in organizations to manage team members and discussions amongst team members are made easy using Slack. It helps us to clear the thoughts and doubts amongst teammates to avoid wrong interpretations and develop a refined product unanimously. So I would say for any team-based working Slack is perfectly suited and plays a great role.

Slack in used in our organization as a messaging platform over the web, where we connect with our colleagues and share information i.e, files, documents, pictures, etc. Slack is an alternative to most of our bcc's and cc's mail. It is used across the whole organization. Through Slack, we form a small group while working on a project, we do this for quick and easy passing of information.
  • Easy to use. Nice UI and UX.
  • Get a notification for every message that we receive.
  • Can form a small group to communicate with others while working on a common project.
  • No automatic messaging send option available.
  • Sometimes message notifications are received with some delay.
It is best suited in all sorts of organization, small or big, it well suited in all firms. Its best use is that it can be used to form a group for communicating with our colleagues while working on a common project. It also can be used as a reminder for our important stuff.

We use Slack across the whole organization. We have channels for different departments/teams, as well as inter-departmental channels, and heavily use the direct messages. It is used for discussions, and for support, including sharing screenshots, etc. It is also needed for looking back at older conversations, and to reference tasks/decisions from the past.
  • Chat history. You can search the history of chat channels or direct messages, even if you joined at a later date.
  • Integrations. Many supported apps, such as Google Drive, Jira, etc.
  • Use anywhere. Can run as a program on the computer, or just in a browser, or on mobile devices.
  • Left Navigation Pane. The left nav is not able to be resized, so I can't actually see the whole channel or person name. Really annoying when the phone extensions are added to the end of the names, but they are hidden by the left nav.
  • Conversation List Sorting. The conversations, specifically the direct messages, auto-sort, and auto disappear based on what Slack thinks it should do. I constantly have people/conversations missing from the left nav and have to search for them manually.
  • More-Actions Bar. The "more actions" bar that shows up at the right of the conversation view frequently gets in the way of actually clicking/highlighting text in that conversation. It needs to be set to not be on top of the conversation that is being hovered over.
Slack is good for team collaboration and discussions, and for one on one messages. It is very useful to be able to search through conversation history, and for new members of channels to be able to see the complete history, and not just from the point that they joined the channel. It is also useful to be able to be logged in and use it on desktop and mobile device at the same time.

We use Slack throughout the company as well as a communication tool within the incubator program our company is in. It has been an excellent way for everyone to communicate, share ideas and to stay on top of tasks and projects that are ongoing. I also use Slack as part of another organization that I collaborate with and it has been instrumental in everyone staying informed on the day to day activities that are taking place.
  • Being able to create channels is a great strength. It allows team members to be grouped and in-the-know where necessary, while not needing to be notified when it's not applicable.
  • The "Do not disturb" feature is a simple, but important one to have. It's a great way to be able to turn off and tune out of work during personal time.
  • Sharing files and links is super simple. Being able to go back and reference them and easily find them makes it instrumental as a communication and collaboration tool.
  • When it comes to direct messaging, I wish that the most recent messages would automatically be listed in the section below the Channels section. If you want to see your most recent direct messages you have to swipe sideways when looking at the channels screen (on mobile) and then see your most recent messages. Just seems like an unnecessary extra step.
  • While I love the "do not disturb" feature, I think Slack should make it clear that by default it turns on after a certain time. When downloading and using the app for the first time I couldn't figure out why I wasn't receiving notifications. It wasn't until I learned about Do Not Disturb that I realized I had to change my settings. It should be something that a new user is made aware of when first downloading and using the app.
  • I don't know if everyone experiences this or not but it seems to me that the desktop app does not update as instantly as the mobile app (I use a Mac). It's not an issue of my internet speed as we have a perfectly fast connection, and besides, my iPhone is connected to the same network. The desktop app just seems to lag a little.
It's great as a business communication and collaboration tool. I know people who like to use WhatsApp for their business communication but I find Slack to be far better suited for business (as it's intended) and WhatsApp for personal use. In fact, I find Slack to be a little cumbersome and overkill to be used just as a personal messaging tool (although it obviously can with the free version).

Slack is our central messaging tool internally to all users within our organization. We use Slack to create groups, channels and to share files. It is a central messaging tool to immediately contact someone within our organization. I use this app more than any other tool due to its versatility and capabilities.
  • Messaging - quick, efficient and reaches your contact every time.
  • Sharing - file sharing and screenshots are available privately or in a group.
  • Group messaging - group messages and channels help organize communication and keep everyone up to date.
  • More app integrations.
  • More custom emoji - it requires your organization to work to do this.
  • Move sidebar - the sidebar cannot be adjusted.
It is so easy to use and really helps when you use emojis to lighten conversations. Slack is best when needing to communicate with one person, a group or the entire organization. We use it to spread messages, alert team members and keep everyone in the loop. Instant messaging just got simpler!

  • File sharing
  • Mobile App and push notifications
  • Web and Desktop apps
  • Create Groups, Create chat between particular peoples
  • On the desktop app, Slack picks the organisation name from email address, but sometimes it might happen that email is different than the organisation name so it redirects to a wrong namespace.
Notification system for any communication tool is very important so slack is good for that.
The second thing is the Integrations:
1. JIRA updates
2. Deployment Robots
3. Security Robots
