What is an email domain?

An email domain is the portion of an email address that appears after the @ symbol.

For example: in "hello@yourcompany.co.uk" the email domain is yourcompany.co.uk.

With free email tools, that part of the address belongs to the provider — that's why you end up with addresses like @gmail.com or @outlook.com.

A custom email domain puts you in control. You pick the domain and create as many addresses on it as you like — think "name@yourcompany.com".

How to pick a great email domain

The best email domains are instantly recognizable, easy to spell, and simple to type. Your business name — or something closely tied to it — is usually the smart starting point.

Brief names stick in people's minds and are harder to mistype. Skip numbers, hyphens, and filler words unless they genuinely add value.

Go with a name that people can quickly link back to you or your business.

.com is a solid choice, and plenty of other extensions are out there too. If your top pick is already taken, a different ending might be the smarter move.
