What is an Email Domain?

Before going into custom domains, let’s define what an email domain is first.

An email address typically has a format like Let’s break down each part.

The email domain is located after the @ symbol. In this case, the domain is “mailfence”. The domain basically identifies to which server emails need to be routed. When somebody sends an email to an address, the email provider knows to route the email to Mailfence’s servers.

Right before the @ symbol, we have the username. This identifies the recipient of the email within those servers.

Finally, the “.com” section is called the Top Level Domain, or TLD. This could be .com, .org, or country-specific TLDs such as .be, and more.

What is a Custom Email Domain?

Now that we’ve identified what an email domain is, what is a custom email domain?

When you create an account with an email provider, you get their default email domain.

Want to create a Gmail account (we advise against it btw)? That will be “”. Want to create a Mailfence account? By default, that will be “” (even though we let you set your own email domain, more on that later 😉).

However, you have surely seen people using email addresses such as “”, or “”. That is precisely what a custom email domain is.

A custom email domain is basically your own personalized email domain. You are still using Gmail or Yahoo or Mailfence, but you are simply replacing their default domain with your own.

But how do you get your custom email domain? Where do you get it? Do you need to pay for it? Let’s answer all of these questions.

How Do I Get My Own Custom Email Domain?

A custom email domain must be bought to possess the right to use it. This means there are two steps you need to follow before being able to use a custom email domain:

  1. Step 1 – Registering a domain name
  2. Step 2 – Setting up that domain name for your email address

Let’s explore both these steps.

Step 1: Registering a domain name

Before you can create a custom email address, you’ll need to register a domain. This is the address that a visitor might type into their browser to access your website.

For example, let’s say your business is called Flying Donuts.

Your goal would then be to buy the domain “”. You can then use that domain for your custom email address (for example, “”).

To register a domain name you’ll need to:

  1. Find an ICANN-accredited domain name registrar (popular choices include GoDaddy and BlueHost)
  2. Search for an available domain name (meaning no one is already using it)
  3. Choose your domain name suffix (.com is the most popular choice, but there are also .net, .io, .co, etc.)
  4. Purchase your domain name (the price will depend on the registrar, but on average it will cost you around $10-15 per year to get a domain name. If your domain name is sought after (like one-word dictionary names), it will cost you more.
  5. Finally, add WHOIS privacy. WHOIS is a public “address book” of the Internet, which means that anyone can find out that you own a specific domain. If you don’t want that, check if either your domain registrar or the hosting provider has a domain protection plan.

Let’s come back to Flying Donuts. I’m going to check on GoDaddy if the domain name is still available:

Unfortunately, that domain name is no longer available 😔

However, if we go to, we are redirected to a page telling us the domain is actually for sale:

The only question now is do we want to spend USD 995 for this domain name. Otherwise, Bluehost shows us other TLDs for which this domain is available:

Once you’ve registered your domain, it’s time to set your custom email address.

Step 2: Using your domain for a custom email address

Once you’ve purchased your domain name, it’s time to link it to your email address.

Each email provider will have different steps that configure your custom email domain. Let’s look at a few.
