We have the same setup. What we do is to send an e-mail every two weeks before the rebill, with a reminder that it's about to happen, and that if they want to cancel, they need to take care of it before <%= rebill_date %>.
Even with that reminder, we still get occasional e-mails from people who didn't see the e-mail, don't have access to that e-mail address anymore, or, for whatever reason, didn't unsubscribe in time. We just refund the charge and delete their subscription.
For what it's worth, we also get e-mails from users who comment on how much they love the app, how they use it all the time, and how happy they are to sign on for another year.
If you want me to get into the details of our code, let me know.
