- Flexibility around notifications. Being part of a 1200+ employee company & a member of multiple channels & groups in Slack, it's fantastic being able to control that notifications I WANT to receive (and which I'd like to "mute," another helpful function).
- The ability to create separate "channels" & groups. This has been key in making sure communication is organized & categorized in a way that makes sense. For example, we have separate channels for announcements, tech-related troubleshooting, different departments, etc.
- Ease of use & just plain fun. With emojis, "reactions," and gifs built in, communicating can be quite fun :)
- A channel initially created as private can't be changed to public. (However, the reverse is possible -- public channels can be made private.)
- The flip side of all the features, functionality, and "fun" aspects of Slack is that it can be a distraction from real work if you're not careful (there IS such a thing as falling into the Slack rabbit hole!).
- 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 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 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.
- 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
- 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.
- 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.
- Multiple channels/groups for a specific purpose.
- Excellent functionality for code snippets.
- When pasting a large code snippet it hangs and has to be force closed.
- Video calls can be improved by giving more functionality like pass control and so on.
However when it comes handling a video call where multiple people speak and they are sharing the video and also want to share the screen or maybe request access to control the desktop, Slack needs improvement and it's less apt.
- It's PERFECT for getting quick answers and having quick light conversations with coworkers.
- Downtime is very rare.
- It integrates well with other programs and has great little add-ons.
- It can become a crutch when people become so accustomed to instant answers.
- Can hinder productivity with add-ons and apps like Giphy.
- It has a nice UI and is easy to set up and use. New team members could easily get updated from a particular channel as well.
- It has both mobile and web-based versions available allowing us to use it on the go.
- It is free for most of the cases and allowed us to create different channels or groups for different departments, teams or projects.
- It offers easy integrations with most used services like Google Drive, GitHub etc.
- Its paid plan is very expensive for startups and businesses having low revenue/big teams.
- For large organisations too, it creates chaos because large numbers of users generate large data. Slack does not support much management of this.
- Sometimes it looks like we are using a messaging app instead of a professional service, as it has all the features of instant messaging apps, like emojis, etc. Professionally sometimes, these don't seem to be useful.
- 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.
- Perfect integration with external applications. The catalog is huge and responds before many needs of the digital work world.
- Instant messaging is on another level because of all the features in the chats. The threads are great to continue a conversation.
- Segment communication with channels that can be created at will. It's great to talk about various topics without mixing them.
- The Search Bar is great: search even within the content of the documents shared.
- At first, it is difficult to use Slack. It has many functions that are not intuitive to learn to use.
- The browser application sometimes does not send notifications on time.
- The license is expensive.
- 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.
- 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
- 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.
- 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.
Also for organizations with multiple derpaments/divisions, the channels provide a natural solution to have both general communication and group-specific communication.
- 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.
- 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.
- Good for individual and team communications
- Sharing documents and images, keeping confidential data in a private chat room
- Maintaining corporate privacy
- Securing data, and [ability to] delete it later as the scope gets diminished.
- Linking with a Video chat conference tool e.g. Zoom or Webex
- Linking a message with a telephone text or voice notification for after hours support
- Creating a private Chat room, sharing confidential data, allowing modifying/ deleting or updating previous messages.
- Securing data and important notes used in a group chat or private room
- Managing Messaging Thread
- Sharing important documents and images
- 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.
- 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.
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.
- 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 offers notification features for different departments.
- Slack allows one to send private messages to administrators.
- Slack allows one to send group messages.
- Slack could allow for a video chat feature.
- It needs to feature more emojis and stickers for its messages.
- It also needs a voice messaging feature like Whatsapp.
