"Advanced Unsubscribe™" is small and free utility software which is designed to help you with your email list management. Many times you get removal requests with an email address which is slightly different from the one in your list. If you use the usual tools for removal (unsubscribe), these addresses will not be removed and therefore this is a source of ongoing upset for your subscribers and ongoing headache for you!
This smart utility allows you to define a list of domain aliases: these are domain names which have more than one possible name, while all lead to the same subscriber inbox. When you use this utility you can be sure all possible domain alternatives have been considered, and that those removal requests have actually been unsubscribed.
