Not sure if this is the right place for this question, but I'll give it a shot cuz its an easy first step.

I've been getting duplicate emails this season for everything, and I believe it might be b/c I am registered under both my current email addy and a previous one that forwards to my current one. I need to unsubscribe from my former email, however I can no longer send emails through that account, and therefore I don't think I can simply send an email to the "unsubscribe" addy listed in the emails to get rid of the old subscription.

Is there another way I can have a subscription ended for an account I can no longer send emails from?
