Not looking to spam random people. We have a database of about 2.2 million contacts we regularly send to. I am looking for someone that can guarantee inbox delivery, who uses feedback loops, has good ip sender reputation, can automatically break up emails to send from multiple places, can track opens, clicks, spam reports, unsubscribes, as well as validating emails before sending, removing bad emails, old emails, etc. etc. Looking for the real deal for a long term relationship, this is for a large corporate entity. We have not been properly monitoring bad emails, and removing them, and that kind of thing, and so because of the volume, it's hurt our sender reputation and we've had some issues with the list. Mainly, those who are expired customers who were not removed out of the system and have remained in there for a damn decade give or take!
