What's a good conversion rate on a simple 1 field email submit?



Well considering that at a 103.45% conversion rate you'd only be breaking even, you gotta aim for 105.34% and higher. If you are converting BETWEEN those two numbers you do risk getting canned by the advertiser for fraud traffic. So watch out broski.
 
depends on traffic source for sure. i would say about 25-40% is decent. Conversion rate is shit, its all about epc. Get a epc of about .40-.50 and you can make it work again dependent on traffic source.
 
I have noticed with most of our email submit offers that a good conversion rate tends to be in an around 40%

Anything less than 25% we usually don t keep on board too long
 
In early 2008 I was getting 80% conversion on a prepop zip submit. I was doing something like, "See if you can get this offer in your area...".

Lasted a few months before it got pulled.
