Threads
Threads keep side conversations out of the main channel feed. They're the simplest and most underrated feature in any chat tool ā use them aggressively.
Starting a thread
Hover any message ā š¬ Reply in thread. Type your reply. Send.
The original message stays in the channel with a N replies indicator. Click the indicator (or use the right-side thread pane) to see the conversation.
What goes in a thread
Good candidates:
- Follow-up questions on an announcement
- Discussion of a shared link
- Troubleshooting a specific error
- Anything that would otherwise push unrelated messages down the channel
Bad candidates:
- Brand-new topics (make a new top-level message instead)
- Messages that everyone in the channel needs to see (they're easy to miss in a thread)
Notifications in threads
By default, you receive notifications for threads where you:
- Sent any message (you're auto-subscribed)
- Are @-mentioned
- Subscribed manually (thread menu ā Follow thread)
You can unsubscribe from a thread at any time ā useful when a conversation you started goes off the rails.
Thread navigator
The Threads tab in the sidebar lists every thread you're subscribed to, across every channel. Ordered by most recent activity. Click a thread to jump into it without leaving your current channel.
T in the sidebar toggles the navigator.
"Also send to channel"
When replying to a thread, there's a checkbox: Also send to channel. Use it when the reply belongs in the main feed too (e.g., a summary of a long side-thread).
Unchecked by default to encourage threading hygiene.
Moving and converting
- Move thread (admins only) ā relocate a thread to another channel. Useful when a discussion outgrows the channel it started in.
- Convert to message ā promote a thread reply to a top-level channel message.
Both preserve history.
Reactions and attachments
Threads support everything the channel composer supports: reactions, code blocks, attachments, mentions, polls. No distinction.
Retention
Threads inherit the parent channel's retention policy. When a parent message expires, the whole thread goes with it.
Archiving threads
Closed threads don't need manual archiving ā they just fall off the navigator after 30 days of inactivity (still searchable).
