"not trying to shill SES specifically"

i didn't assume that. obviously you can only talk about the one that you are using, and while the general setup applies to other such services, i can now file SES as an option that works. and with that price point i am probably going to be to lazy to look for alternatives. (although i should check if the email service i am already paying can do that too without requiring me to send all emails through them)
