How to make money with exit traffic

Came across an interesting program this morning that makes you money when someone leaves your site. I've applied to the program but there is a 3 day review period when they check your site over to see if they think it is suitable. If I get any more information I'll post it here.

A good day yesterday for my own and affiliate sales. The fact is that when you write to people via an emailing list it nearly always generates some sort of activity whether that be AdSense clicks or affiliate sales or 2nd tier sign-ups.

2nd tier sign-ups are often rather disappointing though because 99% of people never really do any active promotion which means you'll never make any money off them.
