Threads let you respond directly to a message in a channel, keeping the replies, images, and other files organized neatly in a single, threaded conversation. Threaded replies and their files stay connected to the original message, and only those who have contributed to or are following the thread will be notified.

Why use threads?

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

Thread etiquette: Yes, it's a thing! Jump down to our Leather Dressy apricot Pointed Toe Flats Loafers Cap Nine Elegant Ballet Seven Suede Women's Handmade wqEO6z for more. ✨

Ask questions, add context, or give feedback on a specific message or file — all without disrupting a channel's flow.

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

  • 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 regular message in Slack.
