When it comes to e-mail submits here's the issue. In all honesty I'd say every email submit company I dealt with didn't really want search traffic. They bitch and moan as it doesn't back out for them like email traffic does.
A short lesson on email submits for those of you that think they're just paying for the email:
I highly suggest you go through the process on any offer you truly plan on promoting heavily. But in this case email submits make money not really by gathering emails rather by what's called a co-reg path. If you fill in an email submit the second page they want to gather your personal info, "to get the prize".
Then on the 3rd page you'll find a list of offers which people have to fill in so many to "get" the prize. Do they really get the prize if they fill out the offers. In most cases, yes. However I'm sure there's shady advertisers out there. Guess what though 98% of people never fill in enough offers. Some people fill in 1 or 2 and then never do more. And you guessed it that becomes the revenue.
If they do fill in enough to get the prize the advertiser makes more then the prize cost.
So with that said the advertiser the advertiser figures out how much your traffic is really worth and starts scrubbing until the make it profitable.
This is how email submits work which is why I honestly just don't like them. You can jump around from network to network or advertiser to advertiser. But honestly is that really a long term business model? If you wanted to make a couple bucks sure that's fine but if you're going to stay in this game a long time my guess is you're not going to mess with email submits that long unless you just can't monetize traffic in any other way. You'll always be chasing.
Email submits are a step above adsense in my opinion. You can throw crappy generic traffic at them and they might make you a few bucks here and there. But the better you get at targeting your traffic to your offer the more money your'e going to make.
Just my 3 cents.
P.S. this was all with regards to search. Email to email submits is a different story
