I want to give away a prize and have people fill out an incentivized offer in order to be eligible to win the prize. I am going to use a drawing to decide who wins the prize. Is there any way to gather the email addresses of all of the people that sign up for the drawing? This way, when the drawing is held, I can email the winner and get their information and mail them their prize. If there is a better way to do this than some kind of a CPA gateway, that would be cool, it was the best idea I could think of. Any help is greatly appreciated.
