Suppressions

A suppression stops mail to an address for your team. sesameSend adds them for you, and you can manage them yourself.

• A permanent (hard) bounce.
• A complaint.

Both come from SES events and are recorded before the event itself, so a crash never leaves a bounce without its suppression. Each fires suppression.added. A send to a suppressed address is skipped and recorded as an email.suppressed event.

• GET /suppressions lists them. GET and DELETE /suppressions/{suppression} take an ID or an email address.
• POST /suppressions/batch/add and /batch/remove take up to 100 at a time.

Topic opt-outs are separate: a contact who opted out of a topic is also skipped for that topic's mail. The simulator address suppressed@resend.dev produces a suppressed event without touching your list.
