Slack Connect lets users work alongside external partners and customers in Slack channels, to speed up projects and strengthen relationships.

I use slack for communication with my teammates as well as to notify team about the website down alert triggered through datadog and alert via slack channel. The notification system is very good according to me as in it automatic mutes the notification during sleep hours so it maintains the work life balance.
  • Integration with 3rd party apps
  • Send Files
  • Chat
  • User interface can be improved
  • Search Functionality within chat
  • Video buffering issue
Slack is mainly used for communication with team. We have a situation where in half team works from office where half of them works from remote location there slack comes in to picture which brings the team work together and maintain in same page. Also we integrate slack with data dog a monitoring tool that triggers a notification via slack and inform us if any site down alert triggers.

Internal communication between the teams seems to be cumbersome previously as we were relayed on the old legacy chat communication model from the google product and doesn't help us any way in terms of the feature and lead to manual intervention a lot. Our management felt it would be great if we have an all in one solution to resolved different issues so they cam across this special tool that helps us making the collaboration easier and communication between the teams made easy with this there by reducing effort and time. We use Slack for our every day communication and any major incidents like war room that connect people from different space to join and collaborate about the issue in a real-time manner
  • Slack call
  • chat
  • channels
  • voice during the call breaks need to be improved
  • Slack channel engagement
  • joining people in the call
To collaborate across the various teams to reduce the back and forth via the emails Slack plays a major role where we can engage multiple teams in a call and resolve the major complex issues. Slack acts as a collaborative tool to communicate between various teams and make business operations easier

We use Slack and an internal project communication tool for software development. It is also very hand to attach files, links and also integrate with third party software's like jira with Slack. The software is flawless and helps us in smoothly carrying out our day-to-day project management, monitoring, team communication, and tracking activities. Multiple projects can be tracked and managed in Slack simultaneously.
  • Multiple projects group can be created and managed seamlessly
  • Ease of communication between different project stakeholders
  • Ease of sharing files and linking with external softwares like jira
  • One major issue i encountered multiple times was in receiving the OTP while creating an account. It takes too much time, and sometimes the verification OTP didn't even come the whole day on the mentioned email id.
After using Slack for almost 2 years now, based on my experience I would highly recommend that any software products / services development company should use Slack as their internal communication and project management tool. It is highly effective, seamless, and also helps in increasing the teams overall productivity. Slack is suited for all levels of organization - small, medium, large.

We use Slack for internal organizational communication. We have also connected several apps to Slack: 1) CRM to Slack to inform us in specific channels about the deals that we have WON or LOST, 2) Bonusly to inform members when they receive a shoutout from other colleagues in the Organization 3) Google Calendar to automatically update status in Slack when someone is in meetings 4) Lucidchart to share workflow diagrams and 5) Clari to share recordings of calls.
  • UI is very user friendly and intuitive
  • Huddle feature in Slack saves a lot of time in organizing and sharing links to connect. It comes as a saviour especially when adhoc calls are needed for short durations.
  • Ability to segment groups based on your criteria.
  • Huddle while a great feature often has issues in terms of connectivity. At least once a week, I face an issue when I am not able to hear the other person or vice versa. Slack can work on improving this further.
  • Slack should have an option to add color to FONTS or increase or decrease the font size. I sometimes feel that I have to use the CODE option to mark lines in RED that need attention.
Slack is a great tool for communication in organizations that have reached scale. It allows you to communicate, share documents, and have short huddles. Areas that Slack can improve upon would be - consistency of huddle communication and clarity as well as providing more flexibility in terms of font, color and font size.

I use Slack everyday. it is the primary tool for communication and collaboration between all my team members and the entire organisation. Slack is the most essential tool to get my job done. It helps me connect with anyone in the organisation. I also get alerts on Slack such as when files have been shared with me, calendar alerts, and alerts where Slack had been integrated with internal tools.
  • I can see the entire history of all the messages I ah exchanged with a person. I can also have access to all the files we have shared between each other.
  • It helps me create groups which facilitates collaboration between multiple stakeholders.
  • I can huddle anyone at anytime and the audio is very clear. I have the ability to share my screen as well, which is very helpful.
  • I can set reminders to messages and Slack reminds me about them.
  • Slack needs to have a task management tool also. This would be very helpful to keep track of my tasks as well as keep a check on my team members tasks.
  • I am not aware of many of the automations that can be used in Slack. Conducting educational sessions and providing demos about features would help in adoption of them.
  • Sometimes huddle does not work as expected. I witness some glitches where my screen is not shared. But this happens rarely.
It is an extremely intuitive, easy to use and reliable communication tool. It maintains entire history of conversations so I can go back to previous messages anytime. It just works really well. It does exactly what I expect a communication tool to do. Also when working with external vendors we have the ability to add them to specific channels with restricted access. This is another plus point.

As a project manager at university, the Slack is very helpful in terms of accessibility and communication with other team members, students, faculty, sharing information is much faster and more organized as it offers different features for communication such as voice recordings, threads, different chatrooms and etc. it really enhances communication
  • easier communication
  • collaboration
  • information sharing
  • search feature limitations
  • file management
I would recommend Slack to a friend as it is easier to have an organized tool of communication in an online platform specifically for work and not to be messed with for different purposes. as it also offers voice recordings, which you can listen to at the speed you want, is a great feature, to listen to voice recordings and the feature that it can do a transcript is even better, however this still needs to be improved.

As an administrative assistant, it is very crucial to communicate with my teammates daily and receive the answers quickly. Slack is very helpful in this matter, because it has the features to have different channels and have them with different themes. option of the voice recording is quite helpful, as it simplifies the information sharing.
  • easier communication
  • voice messages
  • increased efficiency
  • notifications have issues
  • voice recording transcripts are not accurate
I would recommend Slack to my friends, as it offers very helpful features and is a great option for communicating and receive quick responses from teammates, also to have a work related communication solely in one platform and not mess up other communications through the apps that we daily use with friends.

I am using Slack for my daily professional communications and integrations with my apps like Google Docs and Loom Video. I like how it can make channels for each project/task and you can discuss all the details of that specific topic there. I also like the integration of my Project Management software "Trello", because it can tell me about the updates happening in Trello and I can update that cards back by staying in Slack.
  • Communication
  • Project Management
  • File Sharing
  • Integrations with various Apps
  • Backup of messages for low tier packages
  • Nicer way to show the data from integrated apps
  • Time zone / Notifications
Slack is best suited in an organization where you are communicating with your team and want to work on multiple projects. You can make channels to divide it you can send DMs to keep some messages personal. You can reply in threads so there is no miscommunication. You can integrate Apps to get things in one place and much more.

Communication tool for the whole company - DM each other, create channels, receive company-wide communications, integrate with software like Zoom and Outlook
  • Emojis
  • Integration with Zoom (huddle)
  • Keeping you organized and up to date
  • Hard to find where to create a channel
  • It can get overwhelming
  • Search
I think if you want a fun and engaging communication platform for your company it is well suited. But I also feel the majority of use cases are covered by competitor tools like Teams. What is lacking in Slack is an integration with a calendar tool like Outlook, also access to a shared file site like Sharepoint

Our entire team is remote. We are a growing franchise with over 60 locations. Our corporate team and all of our growing locations use the platform. Slack makes it feel like we are all in one big office sitting at the table together. We use it for announcements, quick huddles, daily communication, reminders, canvasses, i think we use it for everything under the umbrella of communication.
  • entire organization communication
  • internal team communication
  • reminders
  • integrations
  • the search feature is not always the best.
I have not found an instance where it does not work well. Slack is great for a team of 5 or 500 in my opinion. It is easy to use. I guess it would not be beneficial for a company who would need it to scale but could not afford the paid version.

We use Slack with channel to set specific scope discussions on products, teams and direct chat communications among the employees. It is easy to use and useful to create public and or private channel among colleagues or with customers.
The use of huddle for a voice call and video sharing is very useful.
  • Quick communications
  • Ability to reach colleagues very quickly
  • Ability to chat with customers quicker than using emails
  • Setting of status
  • Searching of messages
  • Way to organize chats based on tags
Quicker way to communicate, division in channels is very useful. Better experience related to other tools like Skype for business. Clean interface and good customer experience. The new release has a different way of showing some pages. Old way looked better fo my habits but the app improvement is good.

Great tool for teams who work remote, helps us collaborate well and being cloud based means this is great for in person meetings at the office, as well as on the go from your phone or iPad.
  • Teamwork
  • Brainstorming
  • Collating innovative ideas
  • Integration to project planning apps
  • Integration with email
  • Dashboard to plug in database for dev stats
It's a great tool for the remote workforce to brainstorm ideas both inside and outside of meetings. Makes it much easier to contact teammates. Slack is not so great at making calls and video conferencing but hopefully will get better over time.

We use Slack to communicate in our team and as a business at large. The product allows us to easily communicate and share ideas, files and documents. We can easily jump into huddles to audio or video call with each other. We use it all day every day, it is very smooth and seamless.
  • Scheduling messages for later
  • Sharing documents and files
  • Huddling (video and audio)
  • Sharing images
  • Integrating with HubSpot and other apps
  • Grouping of conversations in one place
  • Screen sharing interface on huddles
  • HubSpot notifications could be disappearing
It is so easy and quick to jump into a huddle to speak with my colleagues at a moment's notice. It is a very good way of keeping in touch with everyone, especially as the team grows in size. It might not be best suited to smaller organisations who don't have that many people.

I wanted to share my positive experience with implementing Slack at work. It has truly been a game-changer for our inter-office communications. Slack has proven to be an excellent tool for connecting with the rest of the team. I find it incredibly user-friendly and efficient, making work easier and more productive. My overall experience with Slack has been fantastic. The platform is intuitive, making team communication seamless and enjoyable. I appreciate how Slack simplifies communication, keeps everything organized, and ensures everyone stays connected. It has become our go-to tool for fostering smooth and enjoyable teamwork. The only problems ( not really problems ) was the initial setup and internal onboarding.
  • Team Collaboration
  • API Links to other Applications
  • User Friendliness
  • Mobile experience / great app
  • More flexibility on pricing
  • Video conferencing
  • Knowledge Base
Team collaboration and scraping information through APIs is excellent.

With video calls, we could eliminate other applications.

Communicating and reaching out to Teams and sharing information with everyone. Also, using this to track and find information is really helpful for me as a subject matter expert. This can also help us cascade important reports and announcements. It also helps us to communicate with each other and to support my colleagues.
  • Cascading report to our team.
  • Escalating the important case.
  • Communicating to each other.
  • Slightly enhancing the letter font.
  • Adding some features that may help.
  • Removed some slight glitch.
For me, it is well suited to communicating and reaching out to one another and may help in sharing valuable information that is really important to business matters. It also blends well when it comes to escalating the important cases that may be able to be handled as soon as possible, but sometimes it will be less when it comes to uploading some files due to glitches, but it was a slight issue.

Such a great tool for company communications. Easy to keep overview of everything thats happening, easy to collaborate on projects while working from home.

Slack allows you to create channels for departments and topucs and giving everyone granular access. It's even possible to workw ith externals by giving them guest access to specific channels, or to collaborate with different Sack teams outside of your organisation, simply by linking channels.
  • Clean UX
  • Granular notification settings
  • Integrated Video calling
  • Cross-org collaboration
  • Pricey for enterprises
For any organization I'd recommend Slack over Microsoft Teams in terms of useability.

We're a portfolio business similar to an agency model. Slack Connect allows us to bring our portfolio companies into dedicated channels and manage communication and access for our suppliers as well. I'm not sure we could thrive without it.
  • External channels for clients and suppliers.
  • Automation with app integrations.
  • High visibility of projects to everyone on the team.
  • It can get a bit noisy with lots of channels and threads in particular.
  • Some people take a little while to get used managing comms.
  • It can be hard to find a particular discussion once its a bit older and buried in other messages.
Where you have external stakeholders from your organization, I think Slack shines. Also where you are managing several projects and conversations around specific topics, if you are having one singular topic of conversation and the number of people is small, you could look at WhatsApp, email, or Discord and start to see similar levels of quality of solutions. Slack still solves this scenario very well but the alternatives are similar only a little worse.

We use Slack almost entirely for internal and some client communication. These days, we use it more than we use email. It makes communication swift, simple, and organized. The search feature and thread capability are especially helpful for me. The thread feature helps ensure that people can have eyes on each other's conversations in case there's something that would be relevant to them, but it also keeps the chat from getting too busy.

We have numerous different channels for different functions at the company (marketing, creative, sales, general chat, random). It's a great way to connect with people in other departments, which can be particularly nice in an entirely remote company.
  • Organized chats
  • Search feature with advanced filters
  • Custom layouts
  • APIs with other apps for seamless integration
  • Syncs with my calendar to provide reminders
  • Clearer step-by-step instructions on setting up integrations
  • Easier 'reminder' features for responding to messages
Searching for previous messages and files makes recalling past conversations and to-do's easier. If you want to immediately reach a colleague or client, this is basically a professional texting platform. Email inboxes can get bogged down, but Slack's sidebar ensures that your message gets attention. If you want to provide a positive experience for employees. If you want to preview a photo, document, or other file before downloading or viewing.

You can also immediately start a zoom meeting. Easy features that can be activated with just a forward slash.

As a remote company, Slack is our central hub for communication, where we collaborate on tasks and projects as well as day to day work.

We call each other through Slack, share updates in main channels and use the group chat functionality to ensure we're all on the same page as to where we are on a day-to-day basis.

In short, Slack allows us to function as a remote company in the same way we would in an office.
  • Direct messages
  • Channels
  • Reminders
  • Integrations
  • Threads
  • Canvas
If you are a remote company and you need an easy, structured approach to communication and collaboration, Slack will make your life easy.

The ability to separate colleagues into the channels they will find most relevant and also how quickly you can create direct messages and 'huddles' (calls) mean that you hardly notice you're not in a building with your colleagues. Top marks!

  • Integration with third-party tools
  • Screen sharing quality
  • Catch up feature in the desktop version
  • Read messages keep as unread sometimes
Well Suited: Announcements and updates; Remote work; Team collaboration.

Less appropriate: Share sensitive data; Peer-programming with screen sharing; Share large files; Project management.

The usage of Slack in our organization is by being able to communicate with other department within our account. It is one of the main things that I personally use when I escalate cases to our higher team or executive which is really important to the work load that I currently do in my daily basis.
  • Slack is good for managing threads
  • Slack is great when you want to escalate things with proper documentation
  • Slack has good features that allows the user to customize the thread
  • Design of the interface
  • Customizability
  • Loading speed
I think Slack would be a perfect fit for business related purposes, but if I would use Slack for daily usage regarding about my personal use like social life I think Slack is more inclined to professional use so what I can tell about Slack is that it has all the components of what a typical social media platform is but in professional manner.

Slack is a great tool for team collaboration. For our fully remote team, I can't imagine working without this app. Daily communication, daily meetings, and in-app notifications from other external services are essential for us to keep up to date with tasks and progress in various projects.
  • chat
  • integration with external services
  • web calls
  • small issues with notifications in desktop app
For hybrid and remote teams, Slack is a great tool. For an office team, Slack may be “too much” and can overload team communication.

We use Slack as our primary tool for daily communication and internal 1v1 meetings with the huddle feature. We love how easy it is to collaborate as a team using Slack. It is very simple to set up and use for all ages and technological abilities. Being able to customize different channels is great too.
  • Communication
  • Collaboration
  • Simplicity
  • Interactions
  • Huddles can be tricky to share screens
  • Sometimes Huddle audio is poor
  • Channels can get old and repetitive
We have been using Slack for 5+ years and have found it to be perfect for our unique needs. We love how easy it is to collaborate in channels, react to messages, work together in the canvas area, and have team meetings using the huddle feature. I love Slack and will never use anything else in the future.

Slack in our company is our main collaboration point. We are a full remote company and we use Slack to chat, exange files, make quick call, all in the same place. One of the other great feature os Slack are the integrations, so you could integrate it with calendar, documents, and receive in real time any notification you might be interested in. Last but not less important we also use Slack with guest users to collaborate closely.
  • easy to use
  • complete
  • integrations
  • rock solid
  • weight of the client
  • integration with external users requests several operations to be set
  • pricing
Slack is great for daily collaboration with colleagues and and to be integrated with several external products to receive notifications or make real integrations and start workflow without leaving it. Slack is not suitable If you need to customize the design of the worspace, eg adding webpage, files, or other things into it, and the free version is useless considering it's limitation
