> Use your own domain to sign up for a paid email service, provided by a company that focuses on email.

Note you don't need to pay. just use zoho mail or any other free email that lets you bring your own domain. Switch email providers as needed without changing your domain

The trouble with paying is that if you forget to pay, you may lose email. (arguably this is also a problem with domains, generally you should pay some years in advance)
