I am looking to get Autoresponding software, that would login to Gmail and Hotmail accounts through Web interface, and respond (reply) to received emails, coded.
Software has to be able to process large Size Email Lists (thousands). Email templates used for responding should be easily customizable and have token support. Possibility to assign different reply to different emails group.
Email addresses to which already sent have to be stored into database, to avoid repeat recipients.
Has to have Proxy support.
