Threads

A thread is a side conversation on one message in a channel or a direct message. Replies stay in the thread, so a long discussion does not crowd the channel, and only the people in the thread are notified.

Start a thread

Point to a message and click the thread button on its bar, or click Create thread in the message's More actions menu.

A message can have one thread. You can't start a thread inside a thread, or in a channel you are not a member of.

Thread members

These people are in a thread from the start:

• The person who started it.
• The person who wrote the message.
• People mentioned in the message, if they are members of the channel.

People mentioned in a reply are added too, if they are members of the channel. Everyone in the thread gets push notifications for new replies. See Push notifications.

If you are not in the thread, click Join in its message box to take part. You can only join a thread in a channel you are a member of.

Reply in a thread

Click the reply count under the message to open the thread, and write in its message box. Esc, or × at the top right, closes it.

Leave or delete a thread

Click ⋮ at the top of the thread.

• Leave thread stops your notifications for the thread. You can join it again later.
• Delete thread deletes the thread and all its replies, for everyone. The message it started from stays in the channel. Only the person who started the thread can delete it.

The Threads page

Threads in the left rail lists threads from every workspace. Participating lists the threads you take part in. Other lists threads in your channels that you don't take part in.

Open in channel at the top of a thread goes to it in its channel. The threads of one channel are on the Threads tab of its details panel.

On the mobile app

Tap Threads at the bottom of the screen.

To start a thread, touch and hold a message, then tap Create thread. In an open thread, tap ⋮ for Go to channel, Leave thread and Delete thread.
