There's always the changelog file, right? On the other hand, why not set up a web site with a form that allows your clients to set their own preferences? The form would simply request the user's email address and have a "yes/no" radiobox where the user to indicate whether or not he or she wants to be subscribed to your list. You can than take that data and process it occordingly.
