Its still not that great with its integrations to bots and AI Apps - whoch will really unlock a lot
Its integration to JIRA can be better and its ability to integrate into meetings like Teams is non existent today and needs work

It is the primary means of communication for all of our company's operations. We DM, huddle, and organize our teams by channels. We also use Asana, Figma, and Outlook, but generally there are communication breakdowns that tend to occur, and Slack is the main touchpoint that we update each other on, even when we've tagged co-workers in other platforms. Slack always gets seen. Its mobile app is also very capable for remote work.
Pros
SubChannels
Emoji reacts
Huddles
Screensharing
Easy links in text
Cons
Messages tend to get buried quick on fast moving projects.
There should be an organization suggestion for when people have messy DM threads
Should be able to refine notification settings to only hear from one person, or a few people, rather than types of notifications

It works great for quick, informal collaboration—things like real-time problem solving, fast project check-ins, brainstorming, sharing files or references, and keeping a distributed team connected. It shines when communication needs to be fast, flexible, and visible across a group. However, it’s less appropriate for anything requiring long-term documentation, careful nuance, or formal record-keeping—such as scope changes, contracts, detailed feedback, sensitive HR matters, or client negotiations—where email, meetings, or shared documents provide clearer structure, permanence, and accountability.
In a world of corporate all in one solutions, where businesses are insisting that all employees use Microsoft Teams, Slack is a sleek, fun, modern take on communication which when implemented right in a business, can bring a lot of engagement and life to communication which can otherwise become bland and sterile.
Pros
Engaging communications
Modern design
Enabling features for your work
Cons
Lack of integration with other platforms
Huddles are so bad, you'll have to use Zoom
Steeper learning curve for Microsoft users

Slack is a great communications platform, it's 'Channels' feature is a much better approach to social communications than Team's 'Teams' function, and it pairs really nicely with it's management features and custom emote support. Slack also has some great features such as Canvas which can be used in a variety of ways such as for onboarding employees.
We use Slack to communicate within our team, share updates, and plan meetings. We also use it to connect with the teams of our customers or our partners. Sometimes we also use it to communicate with vendors.
We use 1to1 messages for day-to-day communications, and the channels for company updates and as a central knowledge base history.
Pros
Messaging
Threads
Channels
Connecting with other teams (clients, partners, vendors)
Cons
Desktop app performance
AI automation and workflow improvements
Memory consumption

It's amazing for small team communication. As well as having a dedicated channel with company updates (automated and manual) where everyone can pin in the thread.
This helps keep everyone on the same page while maintaining the async company culture.
It's also really great to keep in touch with customers, and provide direct support without the need to have tickets or another form of format communication.

Direct communication with teams, group chats and channel to bring people and subjects together.
Cons
Limitations on group chats where it's only limited to nine people and then you have to make it into a channel, which is pretty frustrating because you can't remove people out of a group, which is boggling. Drives me nuts.

Colleague communication — that’s what we use it for the most. I think other teams might use it in other ways, but for me, it’s like the WhatsApp of the Salesforce world when it comes to corporate communication. As for where it’s less appropriate, I honestly don’t have an example off the top of my head. It doesn’t replace in-person connectivity, but for remote workers, it’s a necessity.
Slack is something which made, honestly made our life really easy. Right before Slack we used to have a lot of different tools, maybe Google Meets or Microsoft Teams and all the whole idea of using the Slack where we have all the documents, all the information handy. We can create the different groups channel, we can add external people as well. And especially when you're coordinating with the Salesforce team, they are on Slack and without, if you're not on Slack, then you can't communicate with them. That's how it's helping us and our team very well. I think it's a great tool in terms of the communication, in terms of restoring the data, in terms of seeing what kind of the history, in terms of creating the different channels, in terms of sizing, something which is you want to hide from the others, but you want to do collaborative environment. So Slack can come and play a very important, that's what I love.
Pros
You can share the documents link
Create the channels
Invite the unit, the people from the external organization. They don't have to have the paid version of Slack. So teams, if they don't have a paid version, they cannot go for it. But Slack, they can try it, they can use it, and if they love it then they can go for it.
Cons
I mean Salesforce is really the innovative organization. They always come up with a different thought process all. So to be honest, I feel it very good. But yeah, they might want to come up with something different and maybe add down the line in future. So no, not at this moment.
Likelihood to Recommend
See, in every scenario, Slack is good, right? Because it's all about communicating how you coordinate with your team and all. I mean, if there is no communication within the team, then to be honest, you don't need any tools, whether it's Slack or any other platform. So it's better all the different scenario, wherever it comes. Communication, internal, external, sharing the information, creating a group Slack payer. So yeah, it's good.

Each and every member of the company gets a Slack account on their first day, and we use it for all internal messaging and ad-hoc calls. It means that in this working from home age, everyone is simply a message or call away and everything is logged, which is crucial to our businesses day to day operations. It allows for cross-collaboration between departments which would otherwise be made difficult without Slack.
Pros
Ease of use
Simple to implement
Great messaging service
Cons
Ease of use - it is very much a 'pick up and play' software that does not take any time at all to get used to for new starters
Simple to implement - to create new users and just set up and integrate the system into our company could not have been easier
Great messaging service - it is a seamless way of messaging colleagues

Slack is suited to larger businesses that have many employees, as I feel it's main strength is in the way it easily allows you to find anyone to direct message instantly, and how easy it is to setup endless channels to cover all the different departments and projects that may be ongoing at any one time.
Slack has been instrumental in helping us with interdepartmental communications across the globe as well as opening a clear line of communications with our clients. We have offices all over the world and real time communication had been a challenge. With all of Slack's integrations and the ability to send messages as well as files in real time has helped us tremendously. Additionally, whenever we onboard new clients we typically ask that we start a Slack channel for our communications.
Pros
Integrations
file sharing
group chats
notifications
Cons
More options for customizations
Color coded channels
The ability to be see all workspaces in one view
Likelihood to Recommend
Slack has been instrumental in the way we run projects. Because different teams sit in different offices, when we collaborate we always keep logs of our progress in a dedicated Slack channel which can be assigned a different name. Also, we prefer to communicate with clients via Slack if they already have a dedicated Slack workspace and simply ask they create a channel.
Slack is mainly used by our coding team and also the Dev Ops side of the house. We recently developed VoIP software as well as a program called Tadpole to help with the process for setting up a printer. It helps our Team share links to Git Repos and also provides a shareable history so that people can track changes to the software we are producing.
Pros
Helps the team in America stay in contact with the team in India.
Easily share links to Googe Drive, Microsoft One Drive, or Dropbox
Conversations about coding are categorized and archived for later review.
Cons
Some coders feel like it monopolizes their attention.
Can create confusion if some of your team is also using Teams and they don't update Slack.
Trouble with formatting tables that are being imported into Powerpoint presentations.
Likelihood to Recommend
Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.
I use Slack to communicate with my team members. It's better to use Slack instead of sending excessive emails to the team, and by this we can communicate effectively and we can improve the productivity of the work. More importantly its user interface was too clean and clear. I am impressed with some features, like scheduled messages. But sometimes it gets logged out frequently, and I need to log in every day.
Pros
Real time communication with team members.
Organized communication in separate channels.
Sending scheduled messages.
Clean and clear user interface.
Cons
Difficult to find a particular message in a conversation.
Need to improve audio and video quality.
Sometimes I am facing issues with file sharing.
Likelihood to Recommend
In my experience, Slack is ideal for agile team communication, quick updates, and informal daily conversations where transparency is key. It's less appropriate for formal, top-down announcements or highly sensitive discussions, best reserved for more secure, less chatty channels like email. It can also be overwhelmed with notifications in large organizations. That's why I am rating 7.
