Overview

Product Information on Slack

Updated 13th October 2025

What is Slack?

Slack is a software designed for team communication and collaboration, enabling users to organize conversations into channels based on projects, topics, or departments. The software provides tools for messaging, file sharing, and integrating various external apps, assisting in streamlining workflows and centralizing information. Slack offers search functionalities for messages and files, and supports notifications to keep users updated on relevant activities. Its features are intended to address business challenges related to fragmented communication, improving coordination and project management in organizations by consolidating communication within a secure, accessible platform.

Slack Pricing

Slack software offers a tiered pricing model with options including free, paid standard, plus, and enterprise plans. The free plan provides limited functionality and usage, while paid plans are structured on a per-user, per-month basis with additional features and administrative controls based on plan selection. The enterprise plan is designed for organizations with advanced requirements and is priced based on negotiation.

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

Slack Likes & Dislikes

Like

First, it's easy to use, we can communicate with our teammates outside our organization as long as it is approved! Second, is that we can set some reminders, tasks in our slack or even connect it with our google calendar. This really help us be on track on our day to day task.

Dislike

Slack is sitting on a goldmine of conversational data but isn't leveraging it enough. A little bit of AI goes a long way here, as features like smart Thread Summaries, Predictive Reply Suggestions, and Intelligent Message Filtering would completely transform the user experience. So overall it is a great tool with the smarter AI integration that could be exceptional.
