Suppression reasons
When an address is suppressed, it is skipped for future Broadcasts to protect your sender reputation and honor subscriber choices. Each suppressed address carries a reason that explains why it was added and, in most cases, whether it can be removed. Use this reference to interpret the reason shown against any subscriber and to decide what action (if any) is appropriate.
Reason labels and availability can vary by account configuration — (confirm the exact labels in your account).
Reference
| Reason | What it means | Typically removable? |
|---|---|---|
| Hard bounce | The address was rejected as invalid or non-existent (permanent failure). | No — verify a corrected address before re-adding |
| Repeated soft bounce | The address soft-bounced (mailbox full, temporary error) enough times to cross the threshold. | Yes — after you confirm the address is valid again |
| Spam complaint | The subscriber marked a Broadcast as spam (feedback-loop report). | Rarely — only with explicit re-consent |
| Unsubscribe | The subscriber opted out via an unsubscribe link or List-Unsubscribe. | Only if the subscriber re-subscribes |
| Manual / admin suppression | An admin added the address directly to the suppression list. | Yes — by an admin |
| Global / account-wide suppression | The address is suppressed across the whole account, not just one Folder or list. | Yes — by an admin |
| Blocked by receiving server | The recipient mail server refused delivery (policy or reputation block). | Sometimes — after the block clears |
| Invalid / malformed address | The address failed format validation and was never deliverable. | No — correct and re-add the address |
Notes
- Suppression is applied at the address level, so the same person on multiple lists is suppressed everywhere the reason applies (especially for account-wide reasons).
- Complaint and unsubscribe reasons should generally be treated as permanent; re-adding those addresses without fresh consent risks deliverability and compliance issues.
- The example rows above are representative. Your account may show additional or renamed reasons depending on configuration.
- To review, add, or remove entries, see the suppression list management steps.
