Archive doesn't have a single "turn off all" switch for Slack alerts. Instead, each notification type has its own toggle that you switch off individually.
Mute Specific Alerts (keep the Slack connection active)
In the left sidebar, click on Settings.
Click Slack Integration.
Under Slack me when:, turn off the toggle next to each notification type you want to stop receiving:
Macro- and mega-influencers mention my brand
Verified influencers mention my brand
New UGC appears in my saved library view
Turning off all toggles stops the alerts but leaves the Slack connection itself active.
Fully Disconnect Slack
If you want to remove the Archive integration from Slack entirely, this is done from Slack, not from Archive:
Open Slack and go to Tools.
Click Apps.
Find and select Archive.
Click the three-dot menu next to Open App.
Select Configuration.
Revoke access from there.
