Separate Suppression Lists

Bounces, complaints, unsubscribes and manual blocks are rows in your workspace's list. Add addresses or whole domains, check one before you send, and remove an entry when a mailbox comes back.

Independent Suppression Management

Per-tenant bounce lists
Hard-bounced addresses are suppressed only for the tenant that experienced the bounce
Independent unsubscribes
An unsubscribe from Tenant A's email does not suppress the address for Tenant B
Tenant-scoped complaints
Spam complaints are tracked and suppressed per-tenant — not globally
Your admins manage it
Review the list, add an address or a whole domain, bulk-import blocks, or remove an entry that should send again
Suppression Scoping
Bounce suppression per workspace
Hard bounces suppress at once; soft bounces after three in seven days
Unsubscribe lists independent
Opt-outs scoped to the tenant that sent the email
Complaints scoped to source
Spam reports tracked per sending organization
Admin override per-organization
Tenant admins manage their own suppression entries

Questions

Common questions, straight answers.

What ends up on the suppression list?

Addresses that hard-bounced, soft-bounced three times in seven days, complained, or unsubscribed — plus any address or whole domain your team adds by hand, one at a time or in bulk.

Can I check an address before I send?

Yes. The suppressions API has a check endpoint, and every send also checks all recipients — to, cc and bcc — against the list before it is queued.

Can I remove an address that should receive email again?

Yes. Delete the entry by ID or by email address from the suppressions page or API; the next send to that address goes out normally.

Does an unsubscribe in another workspace affect me?

No. Suppression rows carry the workspace ID and sit behind row-level security, so another workspace's opt-outs never touch your sends.
