Postmark Webhooks
Postmark Webhooks connects email delivery events to Drupal’s outbound mail controls. It receives bounce, spam complaint, and delivery notifications from Postmark and checks suppression policy before Drupal sends another message.
What it does
- Retains suppression evidence separately from event history, so routine cleanup does not unblock a recipient.
- Checks To, Cc, and Bcc recipients on supported mail paths. A suppressed recipient blocks the message.
- Provides operator tools for reviewing suppression decisions and retained delivery events.
Included integrations
- Postmark Webhooks Mailer applies suppression policy to supported Drupal Mailer Plus delivery paths.
- Postmark Webhooks Reconcile previews and imports provider suppression evidence for operator-reviewed recovery. It does not change Postmark’s suppression lists.
The module receives events and applies policy; it does not send mail or parse inbound email. Direct mail transports outside the supported integrations must call the suppression policy themselves.
