Channels, threads and direct messages

Channels

Public channels are open to anyone in the company. Private channels are visible only to their members. Use sub-channels to split a large topic — for example #clients with a sub-channel per client.

Channel admins can edit the name, description, guidelines and photo, manage members and archive the channel when it's no longer needed.

Threads

Reply in a thread when a message needs a detailed back-and-forth. The channel stays readable and the people involved get notified about replies.

Direct and group messages

Message one person, or start a group conversation with several people, from New message.

Mentions, reactions and pins

• Type @ to mention someone. Mentions appear in their Activity.
• React with emoji to acknowledge without adding noise.
• Pin messages the whole channel should be able to find, and save messages you want to come back to.

Editing and deleting

You can edit or delete your own messages for a short time after sending. Edited messages are marked as edited.
