These are called email submits and many of the popular networks offer them. Most of the time the network provides you with a landing page and you direct your traffic to it. Everytime someone submits a valid email address you get money. Lot's of diffrent email submit offers out there. The key to sucess with them is finding one that targets your traffic. For example if you have a blog that's about keeping a budget a coupon email submit would probally work rather well with your traffic.
