I am getting fed up 'unsubscribing' from the stuff I am getting.
Never, ever unsubscribe from the spam you get. Most of the time the "unsubscribe" button usually found on the bottom of the spam mail you've got is just there to confirm that your email is valid. Within a few days you should therefore see plenty more of those mails.
The only time I would use this feature is when I unsubscribe from a service that I know (and rembember) to have requested in the past.
