Where Slack shines
- Channel based organization is the best model for team communication. Conversations stay focused, searchable, and organized by topic instead of devolving into chaotic group chat threads.
- Extensive integration ecosystem with over 2,600 apps in the marketplace. Slack connects to virtually every business tool: CRM, project management, code hosting, monitoring, marketing, and support platforms.
- Search is genuinely excellent. On paid plans, you can search your entire message history with filters for channel, date, sender, and file type. Finding a discussion from two years ago takes seconds.
- Workflow Builder puts automation in reach of non technical team members. Create approval workflows, auto responses, channel management rules, and form submissions with a visual drag and drop builder.
- Cost per user is high compared with alternatives. Pro at $8.75/mo per user and Business Plus at $15/mo per user add up fast for large teams. Microsoft Teams is included with Microsoft 365 subscriptions, making it effectively free for many organizations.
- Free tier message history is limited to 90 days. This makes the free tier impractical for any team that needs to reference past discussions or decisions. You feel pressure to upgrade from day one if message retention matters.
