I not A newbie who just know CPA in 1-2 days. My current CPA now have a lot email/zip offer and also allowed incentive. I think Email/zip types not convert very well maybe because advertiser scrubing too much. I need a solid network and I heard EWA is one of the best and have plenty of offer not just email/zip types. My traffic is not blackhat traffic so anyone with EWA can send me PM so I can tell you my experiance and traffic source. I wish I could get in there.
