Other than tracked and optimized Media Buys and PPC, there is absolutely NOTHING more golden than monetized email lists BUT only if the lists consist of individuals who legally and ethically opted-in (and most importantly) are interested to receive updates/daily or weekly news/ discounted offers etc. which all evolve around a certain niche (Golf, Arthritis, Mobile Marketing, etc.).
As for Clickbank, from our 11 years of experience, monetized and professionally "maintained" email lists can generate fantastic conversions with Clickbank offers but again, the offer must appeal to the target audience, the list must be legally constructed, and the offer must convert at a reasonable rate.
We have products which convert at 12.2%-15.1% for targeted email traffic.
Listen carefully, pishty, if your email lists are legal and consist of authentic subscribers who opted-in to join your lists, PM me right now.
Depending on the size and relevancy of your list audience, you can become a rich man in no time. I am not exaggerating or bragging. 11 years of personal experience talking.
PM me today if you're interested.
Mike.
