What are threads?

Threaded conversations, or threads for short, are the easiest way to have a discussion with your teammates on any given topic. Here’s what they look like in action:


Threads are organized into channels so they’re easier to keep track of. Anyone in the channel can see and search for all of the threads inside, but you can decide who exactly you want to notify about any particular thread or comment to make sure they see it.

Why use Threads?

  • Threads keep conversations organized by topic from start to finish.
  • They make it easy to keep track of multiple conversation at once without getting overwhelmed.
  • You can easily catch up on and contribute to a conversation on your schedule – no pressure to reply in real-time.
  • You can quickly search for and find old conversations from last week, last month, or even last year along with all of the original context.
  • You can save and share links to any thread for easy reference later.

Use Threads to:

  • Share progress on projects with a specific team or with everyone.
  • Make team-wide announcements such as new hires or new team objectives.
  • Get constructive feedback on your work.
  • Present and discuss new ideas.
  • Discuss issues and find solutions.

Tip: If you want to share short bits of news that don’t require a longer discussion, share them with the team in a group message. But if you want a group to see/think/debate/discuss something, write it up in a thread. That way, people can get back to it on their own time rather than feeling forced to respond right away.

What are the key elements of a thread?


  1. This is the thread’s topic.
  2. This is a comment from a teammate.
  3. You can reply with your own comment here.
  4. Here’s a list of other threads in this channel.
  5. How many people are following the thread.
  6. Indicates whether you have starred the conversation and offers more handy options (like mark as unread, copy the thread link, delete the thread or edit the thread subject).
  7. Decide who you want to notify.
  8. Add an attachment.
  9. Post the comment when you're done.
