I still use my old college gmail for a lot of stuff. Around twice a month I get some kind of email offer from someone through the system that's being emailed to the whole student body. A lot of times it's about textbook buy backs, renting, etc. Would it be possible for me to take advantage of this? Furthermore, I'm on an email list for job alerts for a govt organization I am a part of. The gentleman that is over all of this sends out email updates of job opportunities. Every email is viewable, and I can't help but think these 150 emails would be good leads for a lot of stuff. Is this the same as purchasing emails?
