Prevent emails from being sent to blocked addresses.
An Email Suppression List contains recipient email addresses that should not receive future email campaigns. Suppression helps protect your sender reputation by preventing emails from being sent to recipients who have unsubscribed, previously bounced, or should no longer receive marketing communications.
SPRL automatically excludes suppressed email addresses from future campaigns, helping improve deliverability and reduce unnecessary email processing.
A suppression list is a collection of email addresses that are intentionally excluded from email campaigns. Instead of deleting these recipients permanently, they are retained on the suppression list to ensure they are not contacted again unless appropriate.
| Reason | Description |
|---|---|
| Unsubscribed | The recipient chose to stop receiving marketing emails. |
| Delivery Failure | Previous delivery attempts were unsuccessful. |
| Invalid Email Address | The email address is no longer valid or cannot receive email. |
| List Hygiene | Recipients intentionally excluded to maintain a clean mailing list. |
Before an email campaign is processed, SPRL compares the selected Recipient Group against the suppression list.
If a recipient appears on the suppression list, that email address is skipped and no email is sent to that recipient.
Navigate to Dashboard → Recipient → Unsubscribers to review recipients who have opted out of marketing emails.
Review this list periodically to understand recipient preferences and maintain healthy mailing lists.
