>I'm thinking of trying to stand up my own server on my own domain and see if I can get a good deliverability established. I've been doing that for decades. I had some deliverability issues back in the early aughts, but I haven't had issues for many years. Over the past decade or so, SPF/DKIM/DMARC and not running an open relay (not that I ever did that) has kept deliverability very good for me. That said, none of the IP addresses I've used are on consumer ISP ranges. That may have an impact too.
