Sending it from your own domain isn’t hard, it’s self-hosting that domain which is hard. If you pay Microsoft or Google using your own domain works well.

I use smtp2go for sending, it's easy to setup your domain with them, and they are free for low volume (1000 emails/month) senders. Emails never get rejected, guess they know their game.

Co-incidentally, we (sqlitebrowser.org) switched most of our stuff to them over a year ago, and yeah they've been hassle free.

Currently using their lowest paid tier US$10/month, as that's 10k emails a month which is far more than we send. At least at this stage. ;)

Wish they'd occasionally look over the PR's submitted to their GitHub repo's though. ;)

It is, but OpenID didn't have this problem because requests were always initiated by the other party.
