I am looking for a sponsor that buys email addresses - What is the best one?

If you refer to buying email addresses submitted by surfers on your sites, and not in bulk from you, then these are very good:
CECash
Freepassbucks
Wegcash

Thanks Cash -
Yes, I have about a hundred or so free sites and I collect quite a few emails for my own email marketing - I want to add one or two partner boxes.
I am not into bulk off-loading my emails - If I did that, I would probably make a quick profit, but lose in the long run.
My emails aren't for sale or trade - Simple as that!

EasyFun -

We pay up to a $1.50 per confirmed email:)

Looks good to me, TondaB.
Many thanks :thumbsup
