An email domain refers to a specific company or organization in which a collection of email addresses exists in “,” with the username being unique to each employee or member of said organization.

For example, if an individual wished to send an email from their Hotmail account to a friend who also used Hotmail, they would type in “” behind their friend’s name in the “To:” field and then click “Send.” This is due to being that person’s email address provided by their respective internet service provider [ISP].

In most cases, when sending an email, clicking on your recipient’s ISP directly will automatically fill it into the “To:” field of your email.

A person can also send emails from their “” or “” addresses to contacts with the same respective ISP, which is more common than sending a web address where both sender and recipient are Hotmail users.

These are just three of the most famous examples of different organizations that have become recognized for providing free email services. However, there are many more companies today that offer email services in addition to paid hosting solutions.

What is the domain of my email address?

There are several common types of email addresses, like:

“”, or “”. The part after @ symbol is the domain name. Your actual email address consists of two parts: 1) your username (the part before @), and 2) the domain name (the part after it).

For example, if someone’s email address were, his username would be ‘john’ and would be his domain name; if someone’s email address were, her username would be ‘jane’ and would be her domain name; etc.

In general, the username is one word, and the email domain name is several words. For example, would have a username of “your user name” and a domain name of “” However, there are some cases where this isn’t true; for example, if someone had an email address like this:, his/her username would be firstname_lastname (because he/she can’t use spaces in their email address). His/her email domain name would be (note that generally, no two domains will end with the same top-level extension). Generally, the only part of an email address that you need to worry about or change is the part after the @ symbol.

What is the difference between a domain and an email address?

A domain is an address used in all your email, for example, It also may be referred to as a “sub-address” or “email account.”

Domain names are typically purchased from an internet service provider (ISP), but it’s also possible to buy them from other companies that sell domain registration services.

The process varies depending on whether you want to use the domain with your existing ISP or get a new one. Most ISPs will provide instructions for transferring your domain name to another provider if you wish to change providers.

If you transfer your domain, make sure to retain any contact information associated with it because this data will not be transferred along with the rest of the site.

For example, your name, Joe Smith, may not be available for registration as a domain name because it may already exist or is reserved for some other use. If the desired domain isn’t public, you can either pick another one or ask if your desired name can be secured so that nobody else can use it.

It’s important to know that reserving an internet address does not guarantee that you will eventually get to use it as your domain name. Domain names must still be registered and paid for before they become active.

How can I create a free email domain?

All the steps to create a domain are simple enough to bypass or ignore many details quickly.

  1. Research all the companies offering registration services, select reputable, show reasonable pricing, have no hidden fees, and accept credit cards.
  2. Fill out an online form with your desired name, address, email address, and contact information for your domain’s registrar so you can administer it later if necessary.
  3. Use this company’s username and password to access your account after you have registered it so you can change settings, collect emails from contacts who will receive email notifications about updates or transfers; etc.;
  4. Watch as your registration completes and your new domain is added to your account. You should see an option to change the nameservers, which allows you to designate where and how other sites on the web can link up with yours.

What are the types of email domain names?

Email domain names are of four types, namely:

  1. Personal email address – These addresses are for personal use only.
  2. Corporate email address – Companies or organizations use this to send business emails to their employees or customers.
  3. Classified email address – The classified domains specify the type of mail that one receives in his mailbox.
  4. Free email address – These domains are free, and they help people save some money when it comes to using an email service provider (ESP).

Can I create my custom email domain?

You can try to create your custom email domain. If you don’t mind, it takes some time. But there are a few limitations you need to consider first. I will try to cover all this in this article.

Because our platform is built using cloud services like AWS S3 and Route 53, we do not have complete control over the DNS settings of this service.

Therefore, creating sub-domain namespaces with custom domains might require additional access that must be gotten separately from Amazon or Route 53 before successfully mapping it to our account.

This means it would take us longer than anticipated to get things ready for you because either Amazon or Route 53 requires additional verification for your request (they want more information about you).

Since the platform is built using cloud services, some sub-domain names might be reserved by AWS or Route 53. These are reserved for our use only.

Therefore, you will not create a record with these sub-domains because there isn’t one available since we already take it up. For example, if you try to make, this would have been created, but there will be no a records associated with it because it points to nowhere since we are using this namespace ourselves.

Although creating CNAME records is supported for your custom domains, this doesn’t mean everything can work out of the box just like that without any problems.

Some providers support CNAME Flattening, which includes Cloudflare, for example. In this case, when using a CNAME record to point your custom domain to cloud flare, the DNS query that is being sent over from Cloudflare back to our platform would have been asking our CDN endpoint with a specific pattern in it like

Because we do not own any domains ending with xxxxxx. We do not know what xxxxxxx means either (this might be an older service we did not add yet).

We need to find out what’s the proper response here before sending one over. For this reason, you will end up waiting until we can get that sorted out first before you are able to use your custom domain.


Email domain names are of four types. These email domains can be classified as personal, corporate, and free email addresses. Creating a custom domain is an option but you need to consider some limitations before proceeding with the process.
