> Reliably scaling outbound mail is the easy bit - the hard part is the reputation management that managed mail services provides, and no specific deployment mechanism will solve that.

^this. if you want to send email its not hard....but if you want that mail to pass spam filters its a different problem altogether. hosted services like SES and mailgun will expose problems in how you are using emails (not handling bounces, not handling unsubscribes, etc) and in our case was very helpful.
