Hello, I have forum with mailing list, I want to earn money selling mailing. Could you recommend any agencies which can help sell it? How much can I earn comparing it into adsense? Let's say if I receive $1 from adsense per click, so how much can i earn sending 1 e-mail?
you can't send it to users if you don't have their permission, about prices it depends from quality of forum and I don't think that theres agecies for it, you need to sell it individual.
I'd think doing ad-swap and promoting you own product will be more profitable. Can be wrong though, never sell an email list before.
