Email submit offer thats iframe friendly?

Hey guys, wondering if anyone can give some recommendations (i'll return with thanks). I'm looking for an email submit cpa offer that doesn't seem to mind getting submits from a sneaky iframe, I expect 0 complaints but they will be pretty much untargeted. Any offer is fine, doesn't matter (e.g. to adult, credit loans, etc). The submits won't know they are submitting their emails so it must be single opt-in. Am I just a noob? Tried 2 submits but neither were paying. Thanks in advance.
