Let Old Slack Channels Retire Automatically
Channel inactive for 30 days? Notis archives it automatically. Your workspace stays clean, your team focuses on what's current, and history is preserved.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Archive a Slack conversation
Archives a slack conversation by its id, rendering it read-only and hidden while retaining history, ideal for cleaning up inactive channels; be aware that some channels (like #general or certain dms) cannot be archived and this may impact connected integrations.
Why this helps
Slack workspaces accumulate dead channels over time—team members get confused about which discussions are active, and cognitive load increases just scrolling through the channel list.
- Reduces cognitive load by keeping the channel list clean and current
- Prevents accidental discussion in inactive projects
- Preserves channel history while making the workspace easier to navigate
- Frees team members from manual cleanup work
Setup
Build it in a few focused steps.
- 1Connect Slack to Notis.
- 2Create automation: 'Archive old Slack channels regularly.'
- 3Tell Notis: 'Every month, find Slack channels with no messages in the last 30 days and archive them.'
- 4Select 'Schedule (recurring)' as the trigger and pick your preferred timing (e.g., 'first Monday of every month').
- 5Test by manually triggering the automation to see which channels would be archived before the scheduled run.
Questions about this workflow
How long before a channel is considered 'old' (30 days, 60 days)?
Mention your preference in the automation prompt: 'archive after 30 days of inactivity,' 'archive after 60 days,' etc.
Can I exclude certain channels from being archived?
Yes. Specify protected channels in your prompt: 'never archive #general, #random, or #announcements.'
What happens to messages in archived channels?
They're preserved—archived channels are read-only and searchable, but team members can't post new messages.
