What people say
"I now use Postal Server for all my SaaS, which is self-hosted via docker, and has all those those features. The good thing is your maintain the IP reputation yourself and your not paying exorbitant prices when sending large volumes of transactional emails (really it's just the cost of the server you install it on)."
