on Gmail, you can also send from your forwarded addresses
I imagine that only works if you also host the address you forward to with Google? Otherwise I can’t see how Google can send email on behalf of a domain whose DNS servers it doesn’t control. If that were possible spam would be a lot worse than it is.

It only requires you to demonstrate you control the address.

Proton, on the other hand, only supports you owning the whole domain, as their only verification is through DNS TXT records.
