Heh, I didn't realize they sold those. I got some a couple years ago as a freebie, not sure it was worth the amount of sophos marketing crap I got for the next year or so after I gave them my contact info.
I have multiple legit emails for that exact reason. We had a competition to see who could get the most marketing rubbish at a university fair (this method meant I won, and also noticed an inverse correlation between academic prestige and marketing spending) and I never stopped.
