I have a food recipe site, and as most of you know, they are nearly impossible to moneytize properly. Thats why I need to have a pop up which will only close after the visitor have given their email. Could anyone help me out, which plugin could make this possible for me? Right now I only get around 10 emails a day without the lock, I want to this split test this feature. Its really only a win-win situation. It makes only around 2 usd - 4 usd a day with AdSense, so I can make much more if I can email farm all the visitors.
