Email Beast is specifically designed to overcome any and all barriers and blocking mechanisms while sending large quantities of emails (including automatic IP address change, multiple simultaneous messages / subjects / senders, and state-of-the-art configuration capabilities). The result is that it easily reaches a speed of over 15,000 emails per hour and more (while sending direct, this is 2-3 times faster than what you are probably used to). Other features include being able to handle multiple dialers in rotation, multiple "threads" or simultaneous connections, 21 different online speed and progess statistics, sends direct or via an SMTP server or both, fast auto-recovery (4-5 seconds) after system crash or power failure, multiple sending 'rounds' to try and retry to send to each recipient address until successful, weekly time table to specify the exact times to send the emails. Because this product is the only one of its kind where there are configuration options specifically designed to overcome bulk email sending blocks such as blocks by IP, blocks by content, blocks by subject line etc.
