Threads keep discussions in Slack organised. They let you ask questions, add context or give feedback on a specific message, all without disrupting a conversation's flow. A thread will remain connected to its original message and only those that have contributed to it or who are following it will be notified of new replies.

Why use threads?

  • Clearly tie your feedback and thoughts to a specific message or file.
  • Organise conversations and preserve meaningful context.
  • Encourage open discussion without distracting others.

Note: Threads is a built-in feature — it's not possible to disable for your account or for your workspace.

Send a reply to the entire channel

Replies to a thread don’t distract from a channel’s main flow of conversation. This helps things carry on seamlessly without disruption. However, if a wider audience would benefit from seeing your reply, you can also post it in the channel. 📢

Reply to a thread, jump back to the original channel or unfollow threads, all from one convenient location. If you have new thread replies waiting, the section will be labelled as New threads instead.

When you’re new to Slack, the Threads view won’t appear on the desktop app or browser until you start your first thread or receive your first thread reply.

Tip: on the desktop app, open the Threads view from your keyboard: ShiftT (Mac) or CtrlShiftT (Windows/Linux).


A guide to using threads

  • Threading vs. sharing messages.
    Threads work best when you want to keep your response connected to the original idea or file. Sharing a message is best used to rekindle past conversations or highlight specific messages from one channel to another.
  • Threads are sticky.
    When you share a message or a message containing a file, any threaded replies will be shared along with the item. This keeps the conversation about the original item ready and accessible.
  • Avoid hiding info in threads.
    A thread’s discussion won’t appear in a channel’s main view unless you share your reply with the channel. If other members would benefit from seeing your message, share it in channel rather than in 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 reply in a thread,
    send it to the entire channel, just like a normal message in Slack.

Threads keep discussions in channels and direct messages (DMs) organised. From any message, you can start a thread to ask a question, add context or give feedback without disrupting a conversation's flow. A thread will remain connected to its original message, and only those who have contributed or who have followed the thread will be notified of new replies.

Why use threads?

  • Tie your feedback and thoughts to a specific message or file.
  • Organise conversations and preserve meaningful context.
  • Encourage open discussion without distracting others.

Tips for using threads

  • Threading vs sharing messages.
    Threads work best when you want to keep your response connected to the original idea or file. Sharing a message is best used to rekindle past conversations or start a conversation about a message in a new channel or DM.
  • Threads are sticky.
    When you share a message or file, any threaded replies will be shared along with them. This keeps the conversation about a topic ready and accessible.
  • Avoid hiding information in threads.
    A thread's discussion won't appear in a channel's main view unless you share your reply with the channel. If other members would benefit from seeing your message, share it in the channel rather than in a thread.
