What to do with email lists

First off, This forum is awesome! I have built up around 20 websites on several niches and starting to have money coming in.

I read a post to put an opt-in signup on the pages and have implimented in on most my product pages. I have around 3000 collected with their Full name, email, zip, and which niche they came from.

My question is, What is the best way to make money off this list?


Thanks!

A) Send emails in your list containing your affiliate link.

B) Sell it.

A is recommended.

Both good thanks.

What about using the information to sign up for offers? Good idea? / Bad idea?

I got a huge e-mail list on the members download area if you want to use that.

I would try to sell the list...
