Suppressions

Blocked recipients (bounce, complaint, or manual). Sends to suppressed addresses are rejected before queueing.

Automatic suppressions

Hard bounces and spam complaints from the delivery stack add entries automatically. Subscribe to webhooks so your app can mirror suppressions locally.

API and dashboard

List and delete suppressions via the dashboard or REST API (scopes as configured for your deployment). Honor complaint and hard-bounce suppressions before removing entries.
