How do I block a subscriber?

Blocking an email address prevents that address from subscribing to your list.

If you block a subscriber who is already subscribed to your list, the system will unsubscribe them from your list. If you delete that subscriber from your list, they will be prevented from signing back up to your list using that blocked email address.

Note: The system will unsubscribe the blocked email address approximately 60 minutes after the subscriber is blocked in your list.
