You don't have to self-host email (which is a pain) with a custom domain. Most of the providers will let you point your domain's email at their servers, with a few DNS entries. The major (IMO) benefit of that is that your email address is decoupled from your email provider, so changing providers in the future doesn't require you to tell all your contacts.
Thank you! This helps, and while it doesn't solve the issue of the @ being recognizable, it does solve a lot of issues.
You would need to register your domain with someone who offers privacy from Whois lookups (they all should). Your contact information will be discoverable with a subpoena. A mail relay like Duck or Firefox would be an additional layer of anonymity but idk how they will respond to law enforcement
