How do I block an entire domain?

Blocking an email domain prevents all email addresses at that domain from subscribing to your list.

Once you block an entire domain in your list, the system will unsubscribe all email addresses using that domain on your list. The system will also prevent any new subscribers using that blocked domain from signing up to your list.

Note: The system will unsubscribe all addresses using the blocked domain approximately 60 minutes after the domain is blocked in your list.
