Suppression List
The suppression list is workspace-wide — an address or domain blocked here can never be sent to by any campaign, not just the one that originally caused the block.
Adding entries
- Block a single email address or an entire domain (every address at that domain).
- Bulk import up to 5,000 entries at once, for a CSV-style blocklist import.
Blocking a domain and bulk import need an owner or admin. Any member can block a single address.
Addresses are also suppressed automatically on a hard bounce or an unsubscribe request detected in a reply.
Suppression is checked when a lead is added to a campaign — a suppressed lead is skipped entirely rather than getting a campaign-membership row that just never sends, so it’s clearly visible as “blocked,” not silently stuck.
Removing an entry
Deleting a suppression entry allows that address/domain to be sent to again on the next campaign it’s added to. Only an owner or admin can remove an entry.
