Deliverability has never been an issue for me since (of course) I run my own mail server. But I doubt it's a serious issue when you take the little time it takes to set up DKIM etc.

I added the simplest and most basic of captchas and so far I got 0 spam. It’s been online for months at this point.
Sometimes a stupidly basic solution works incredibly well.

Fair enough, I assumed this would be an issue so I never explored the possibility of hosting my own mail server.
