Quick Question: When someone requests to be removed from our email list, I understand that we should not email them again. However, if their email address is inadvertently re-uploaded via a different list, could this lead to violations of CAN-SPAM laws? To avoid this, should we add every email address that requests “remove me from your list” or “unsubscribe” directly to a blacklist, ensuring they don’t receive further communications, regardless of any subsequent uploads?
