Reverse pointer is pretty easy with some hosting (Linode) and painful with others, but that's pretty basic knowledge. Same with managing IP reputation. Heck, mail gun helps warm up IPs for you (but if you're not email marketing it's ridiculous to maintain that).
What really gobbles my bobble is BIMI. Even without the paid-for certificate ($1500 is absurd), you can set it up to show your logo, and works on some providers (like yahoo). But careful, you have BIMI without the cert set up? Gmail spam-cans it.
Same with pgp, if you include your signature a lot of providers will immediately increase it's spam rating, usually high enough to land in spam (+7 pts usually), even though I doubt any spammer or scammer is inviting you to encrypted chats.
Email is broken because we all signed up for Gmail and didn't know better at the time.
