Are you familiar with DNS? When you browse to example.com, your computer does a DNS request for example.com, and looks for an A record denoting the server to contact. You've probably fiddled with these when setting up your domain for the first time. Email is similar, but makes use of MX records instead of A records. When you send mail to [email protected], the computer does a DNS request for example.com, and looks for an MX record denoting the mail server to contact. Same shape of thing. So, regardless of what email service you pick: First you'll create an account on the email provider's website and tell them about your domain. Next, your email provider will ask you to prove the domain belongs to you. In Google's case, they come up with a randomly-generated TXT record and ask you to associate it with your domain. So you'll log into your domain registrar and add that record. Finally, your email provider will show you a few MX records, which you'll associate with your domain in the same way. More or less of this might be automated, depending on your domain registrar and mail provider, but at the end of the day it always works like this. If your registrar "offers email service", all they do is run a mail server and configure MX records that point at it. Both Google and Microsoft sell single-person-sized email and office services under the name of "new business email" or "small business email", those might be some good search terms if you're looking for mail providers.
