Slack is an incredible communication and collaboration platform. I couldn't imagine doing my job without Slack. It's a great informal way to get in touch with other teams and people without sending an email.

Collaboration Platform Simplifies Use but Struggles With Message Organization and Noise

3.0
Jul 11, 2025
Easy to use and useful for team collaboration outside of the office, but comes across as basic in what it can do. It can also become messy to maintain chats in the sidebar and I feel other chat based apps work much better overall.

What Your Peers Are Saying About Slack

VP of IT
I am revisiting our messaging retention thresholds more specifically for email (Google) and instant messaging (Slack). Was curious as to what is generally being used as the threshold for these 2 communications tools (i.e.; 30 days, 6 months, etc.)?
Director of IT
I also am curious what other organizations are doing on this front.  We had an event where legal had us put an indefinite hold on all messages (email, IM, etc) and now that has just become the standard.  Would like to compare what other organizations are doing and try to get us back to something that doesn't hold messages forever.

VP SALES OPERATIONS & ENABLEMENT
Does anyone have experience with Slack Sales Elevate or Slack AI?  If so, did you see any productivity improvements, specifically for Sales?   We are looking at Sales Elevate for a few specific use cases: (1) Deal Desk efficency improvements; (2) Summaries of changes made to opportunities for sales leaders; (3) Account planning (there are collaborative templates in Sales Elevate which you can configure to meet your org's needs).   We're also interested because it seems like an easy way to start using AI in a fairly low risk area.   For context, we use SFDC CRM already.

Been disappointed by it honestly, especially when compared to Momentum.io it doesn’t even come close.

    Slack Enhances Internal Communication But Raises Employee Privacy Concerns

    5.0
    Sep 14, 2025
    I have been using slack for about 5 years across my current company and the previous one. overall, my experience has been very positive, as slack is excellent to preserve internal communication, collaborate with colleagues and stay alligned as a team. that said, I am disappointed by the fact that admins have ways to access internal communication between employees. while I understand this may be necessary in certain contexts, it does affect the feeling of privacy and openness that slack is otherwise so effective

    Slack Enables Seamless Collaboration But Notification Volume Can Become Overwhelming

    Sep 9, 2025
    I have used a few different communication platforms and Slack is by far my favorite. There are plenty of features to utilize and collaboration between cross functional partners has been made seamless. Slack is very intuitive and most people should be able to pick it up.
