Suppression is the workspace's list of addresses that must not be contacted.
What lands on it
- Anyone who unsubscribed
- Addresses that hard bounced
- Recipients who marked mail as spam
- Anything you add manually
How it is applied
Suppressed addresses are excluded when a campaign builds its audience, and re-checked before sending. Importing them again does not re-enable them.
Important notes
This is deliberately not overridable. Contacting someone who opted out is both a legal problem and the fastest route to spam complaints.
