Heads up: Email marketing now has a "feature" where even if you unsubscribe, they still keep your email address and can use it to target you with marketing other places. (Also add you to new email lists - technically that's illegal but many do it anyway.)
If you don't already have a throwaway email for all your email subscriptions, now's the time to get one before too many marketers catch onto this new feature.
