I'm trying to move away from Google and replace my Gmail account. But reading about the different options, I'm realizing I don't really understand email at all - e.g. the difference between the client and the domain name, the different protocols, encryption.

Does anyone have articles or books to suggest as a "Basics of Email: 101"? Thank you!

In your case Google would be the host/provider of your Gmail e-mail service and gmail.com is the domain name of the Gmail e-mail service.

Having your own domain name would allow you to keep you e-mail address even when switching your e-mail host. Which means you would not have to bother with re-registering you new e-mail address for every service or newsletter again.

yourname@yourdomain.com would always be yours no matter which e-mail provider you choose, IF they support a personal domain.
