Are there any general guidelines for what to charge someone to email an opt-in list? I have over 2,200 opt-in Forex subscribers and as I haven't emailed them for a while I would be interested in selling someone the chance to send a Forex related email to these people. This is not selling the email addresses, I am only looking at offering someone the chance to provide me with a Forex email I can send to my list with their links in it. So, what would be a fair price? Thanks
