I think you should post the email addresses in a new thread here at GFY.
Or, send a primary email to them asking if they'd like free porn and what kind of free porn would they like, then you'll be able to categorise your emails and target them more effectively when you are ready to advertise shit in there. Plus you'll get rid of those who don't want emails (you can always sell those email addresses later).
P.S. Employ me, I'm a minority.
