ok, so I set up a new clickbank site promoting my product. Basically I'm a woodworking guy, been selling woodworking plans for years on ebay. In that time on ebay, I have amassed a customer list of over 20,000 folks who have purchased from me. What I want to do is use one of those bulk mail services to send all my old customers an email saying, hey, here's my new product, since you were interested in this type of product before, perhaps you'd be interested in doing some affiliate marketing for this and we both make money.... something like that. So, my question is, if you have a list of people who have already purchased from you, is it wrong to send them out an email or two like that using a bulk emailer? Is it against clickbank's policy? I've put so much work into my site, I don't want to get blacklisted over a bulk email.
