Thank you for explaining how this works. Mine is a personal vanity domain with a non .com TLD. But I have the SPF and DKIM setup and I use a well known Google workspace alternative, which I have used for almost a decade now. So ideally I should have checked all the necessary boxes. I hope, I have stumbled into a couple of services that have some poor email verification implementation and my domain has not been blacklisted by some email protection company or something serious like that.
