Message threads

Who can use this feature?
  • All members and Guests can use this feature. 
  • Available to teams on free and paid plans.

Threads let you respond directly to a message in a channel, keeping the replies organized neatly in a single, threaded conversation. Go ahead, ask questions and dig deeper, have side conversations, or go on a tangent without interrupting the flow of conversation.

Why use threads?

  • Encourage open discussion without distracting others.
  • Organize conversations and preserve meaningful context. 
  • Focus your time and attention on the task at hand.

Tip: On the Slack desktop app, open the All Threads view from the comfort of your keyboard:  Shift T (Mac) or Ctrl Shift T (Windows).


A guide to using threads

  • To thread or share a message? Threads work best when you want to keep your response connected to the original idea. Sharing a message is best used to rekindle past conversations or highlight specific messages from one channel to another. 
  • Avoid overuse. A thread's discussion won't appear in a channel's main view, so if team members would benefit from seeing your message, it's best to keep it out of a thread.
  • Threads are courteous. They help keep channels focused and prevent active discussions from becoming derailed. But if you want others to see your message in a thread, send it to the entire channel just like a regular message in Slack. 

Note: Message threads cannot be turned off at this time.
