From the developer:
1and1Mail can be used to send newsletters to multiple e-mail accounts. While sending e-mails, it can change your IP address automatically through various proxy servers so that your e-mail accounts are not blacklisted. It can also change e-mail contents and headers to personalize each mail. Random time lags or random sending frequency feature can mimic manual sending.
