Email Cleanup Follows Channel Cleanup
Your team wraps up a project and deletes the Slack channel. Notis automatically moves related emails to trash so your Gmail reflects the change.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Move to Trash
Moves an existing, non-deleted email message to the trash for the specified user.
Why this helps
Channels get deleted, but related email clutter remains in your inbox. You manually clean up later or leave a mess.
- Keep Gmail in sync with active team structure
- Automatically clean up emails from closed projects
- Reduce manual cleanup work
- Maintain a current inbox without stale conversations
Setup
Build it in a few focused steps.
- 1Connect Slack and Gmail.
- 2Create an automation: 'When a Slack channel is deleted, move related emails to Gmail trash.'
- 3Notis will match channel names to email labels or sender addresses.
- 4Decide whether to trash or label messages (you can also archive to a separate folder).
- 5Test by archiving or deleting a test channel and checking Gmail.
Questions about this workflow
Will this permanently delete emails?
By default, Notis moves them to trash, where they stay for 30 days. You can recover them if needed. Permanent deletion requires explicit confirmation.
What if I want to keep some emails from the channel?
Exclude those emails by label or sender. Notis can be selective about which ones get trashed.
Does this work for archived channels too?
Yes. You can trigger this on channel archival, deletion, or both.
