Traditionally, ESPs have been unable to use AWS for sending mail because AWS IPs have very bad histories of being used for spam (among other reasons). I believe most ESPs are running their own servers for email or using a managed hosting service of some kind that allows them to use private IPs/rent private IP ranges. However, AWS just announced a "bring your own IP" program that caters to ESPs. This lets you use your privately owned IPs on AWS infra:

This makes it much more viable to send mail from AWS, which in turn is much more scalable than managing a colo machine or paying a managed hosting service and probably a lot cheaper. I'd love to hear opinions on what negative effects anyone anticipates of using AWS + private IPs for their mail infrastructure.
