Our e-mail database is updated continuously in order to insure maximum deliverability. Each week, new e-mail addresses are added to our database and are checked in order to prevent duplication and ensure their validity. We remove any e-mails that match those in our most current 'Unsubscribe List'. The end result is a highly deliverable e-mail list which minimizes unsubscribe requests which allow your business to get the most out of the e-mails sent!
