I want to buy some mail traffic per click
 

I'll pay you per click for mail traffic.

$.10 per click.

word of friendly advice:
make sure you know the people sending the clicks or you'll get fucked harder than a hot virgin on prom night...

What do you mean exactly.. 10 cents a click from mailings? Getting the CLICKS from mailings is always the trick. (usually really nice signup ratios, but the mailed out to actual human being clicking is very low.)

You'll probably need to offer a bit more.
