Hey, We just launched a pay per lead program. The way we have set it up, is that a lead is generated everytime someone new enters a giveaway for Pearl Earrings. And the lead needs to click on a url in the email to validate the lead (and to check if they won the earrings). We have set the program to automatically generate a winner 1 in 50 times (it is random, not every 50th person to enter wins).

I pose my question to people that have run pay per lead programs before:
Anyway i can tweak this to maximize the lead program?
