Suppression list

Addresses that bounce permanently or mark your mail as spam are added to your workspace's suppression list automatically, and Flinkk Mail will not send to them again. This protects your domain and the shared sending reputation.

  • Added automatically: permanent bounces and every complaint. Temporary bounces (such as a full mailbox) are not suppressed.
  • Enforced everywhere: the API, agent inboxes and scheduled sends. A message with any suppressed recipient is refused with

422 recipient_suppressed and the addresses. When you send one message per recipient, suppressed addresses are skipped.

Call
GET /api/v1/suppressionsList suppressed addresses and why.
POST /api/v1/suppressionsSuppress an address yourself: { "email": "..." }.
DELETE /api/v1/suppressions/{email}Remove one. Do this only if the owner confirms the address is valid.
