1. I read a post where he said to do zip submits instead of email submits as the conversion rate is 4 times as high. Is this what I should do? 2. I'm kind of confused by the quality to expect from zip submitting with content locking. How can I get a bunch of zip submit conversions but then have people actually sign up for the offers eventually so I don't get banned? What strategies do you guys use when content locking to make sure the quality is high enough?
