Though I've since updated that to include a .txt file as the body vs. typing it out in the email. But that's easy enough.
I might have added TXT records to satisfy DKIM etc., I don't remember. There are guides on the Amazon site; I'm a bit of a dummy when it comes to this so if I worked it out it must have been obvious enough.
Tyvm! If you have pointers to find the guides that'd be appreciate just for the sake of seeing if they're a good option. I'll look either way. Ty for the help
