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!


A domain is a url, like oaksprout.com. A provider is a server/computer that the domain points at. Many services sell both together at an upcharge, but a domain itself usually costs like ~$15 a year
If an IP address is a mailing address, imagine a domain as a way to pay the post office so people can just address it to oaksprout. You could have them forward your mail to your house, or you could send it to a PO box or business address, and change it whenever you want
The provider is like the mailbox in this metaphor… It receives the mail and holds it for you
That’s helpful, thanks
