PHP Mailer Pro
PHP INBOX Mass mailer is a super light-weight system that runs on its own hosting account that uses timed intervals to keep you away from those annoying "sending" screens, or blacklist issues from shared IP's.
Once you've uploaded or paste your list and configured your e-mail message - Click send and have no worries that your e-mail will be sent and land in the recipients inbox. PHP Mass/Bulk Emailer Pro even updates itself with the latest patches when one becomes available!
We've seen those "other mailers" ... You have to leave your browser open and on that page for a solid less than 3 minutes to finish a simple 1,000 e-mail list! If your server or your internet connection has a "hiccup", your campaign is ruined!
