I have been a nightclub promoter for 15 years and have acquired quite a treasure trove of email addresses. About 300,000 to be exact and I?m looking for a solution to get around the various email services that don?t quite live up to what I need. What I?m trying to do is purge the entire list so that only valid emails are left. Then be able to email my customers when I want. I need a proxy server or regular server to handle all of this without being flagged as a spammer. My intention is not to spam but to let my clients know when there is a new party. Does anyone have an easy solution to this problem?
