The problem with self hosted email is that your domain becomes a unique (or near-unique with a few domains) tracking reference.

Only if the entity on the other end understands this though, right? Which they probably don’t.

Otherwise everyone @example.com is the same person.

It's worth a lot of money for the ad-tech (consumer tracking) industry to understand.

If a domain only occurs once in a user database, it's likely to be a personal domain. A data broker that sees the same domain in a few different datasets (once in each) can be quite confident that the domain is an individual's.

They cannot know if it’s a small domain like a business, or a personal catchall. It works fine.
