I've been searching in clickbank for email submit offers, but can't seem to find any. Could someone help me? Cheers.
Yeah, ClickBank is a completely CPS based network. If you're looking for email/zip submits and other offers which the user doesn't actually have to whip out their credit card you need to check out CPA networks. I'd recommend NeverBlue and AzoogleAds both of which I'm a publisher (affiliate) on. However you'd better do your homework because getting into CPA networks is more then just filling out a form. You've got to do telephone interviews for of the legit networks (although I did get accepted to AzoogleAds without one).
