My Suggestion for Affiliate Marketing: Never use Email Submits
After being pissed around by 3 companies (and about 2-3k) in regards to email submit offers I have the following advice:
Never use email submit offers unless you want to risk not being paid.
Most affiliate networks will tell you "Our email submits are converting high and we will pay out for them no matter what"
And thats just a load of crap and a few months down the line and them saying "No we won't be paying out your leads because of some excuse" I'm sure you will be annoyed as I was.
If you want to risk not being paid go ahead :)
