1. Send us your list of "removes" (email addresses of people that have asked you to not mail to them, or undeliverables). We will incorporate this into our complete database of removes. This benefits the entire Internet community so that every mailer doesn't have to find out for themselves who doesn't want email! Send it to our mailbox and put REMOVES in the subject line. The required format is one address per line, ascii text, zipped if possible.
2. Send us a list of email addresses that you want "cleaned up". We will remove all of the bad addresses that match with our database and send you back a "clean" file. Send it to our mailbox with a subject line of CLEANUP. Use the same format as the remove file...one address per line. We can send you the list of emails that we removed from yours by special request.
That's all there is to it!
P.S. Some have asked why we don't just provide the remove database for download. The main reason is that there are unscrupulous emailers that, believe it or not, would use that list as a source for email addresses to send to. We have to do everything possible to make sure the removes are not mailed to anymore.
