Suppressions
Manage the suppression list that blocks emails to specific addresses.
SNDR does not send to suppressed addresses. Addresses are added automatically on hard bounces and one-click unsubscribes. You can also add them yourself (e.g. opt-outs collected elsewhere) or remove one that was added in error.
Removing a suppression for an address that hard-bounced or complained may harm your sender reputation. Only remove suppressions you are confident are safe.
