Selling $50 Ad in monthly newsletter to around 35000 and growing registered members.

I have around 35000 and gradually growing members on 4 different websites and i am thinking of starting sending them monthly newsletters. I never sent email newsletters before and now that i have built a list i have only one short announcement to make. So this is an opportunity for you to put your big text ad as one of the offers in the email. You will get a copy of newsletter and also the reports, but i cannot give you all the email IDs because of privacy policy that websites has. PM me if you are interested. This charge will basically go to the email server and newsletter service cost.
