:) Brings back memories of doing this in 2002 to blast out Student Government campaign messages to students on campus. Back then email servers were very forgiving. I just had a loop that generated all combinations of <phone-number@carrier-x> and send out an email from a campus IP address via sendmail. It was a very effective way to send notifications at almost zero cost.

I did this in college, but with personal contacts because I couldn't afford a data plan at the time or a smart phone. I'd carry my laptop around the mall or connect to random open wi-fis from hotels to email people's phones. All to save a few bucks.
