Hey, Brenda! If you want a domain name email but not a site you might look into G Suite since you already use gmail.
Gmail for business - Get business email, storage and more
Gmail for business: secure business email, 30GB of storage, 24/7 support and more. Includes full G Suite - Google…
It was recommended to me when I started using Upwork, because they have the same email requirement, but I already have email through natedoesart.com so I didn’t need it.
If that doesn’t seem like a good fit you can just google “email hosting” and you should find something suitable for your needs.
Though if you think you might someday build a website you might just want to buy the domain with hosting because they usually come with email hosting anyway and they’re not really very expensive.
Does that make sense?
