I work for a company that heavily relies on email marketing to make money and we're running into a problem. We are trying to spin up a new email server and are finding it difficult to find a hosting company that doesn't explicitly disallow any form of mass mailing, legitimate or otherwise! Our lists are all opt-in, so the legitimacy issues aren't a problem, and we comply 100% with CAN-SPAM laws, but that doesn't seem to matter to hosting companies. Does anyone else have experience in this market? Can anyone suggest hosting companies that either support ESPs or are at least mass-mailing friendly? I've done lookups on most of the big players in the field and it seems that all of them are hosting their own equipment, which is currently cost prohibitive for us.
