Google offers free email domains, but it also allows you to create unique email domains for an additional fee. Of course, it’s not the only platform that has this function.

Why Do You Need a Unique Email Domain?

No matter what platform you use to create a unique email domain, its benefits will be more or less the same:

1. The emails will go to the spam folder less often. If your email address has a unique email domain, you can set up authentication methods Authentication methods help protect
your email domain from
phishing, spam attacks, and
other cyber threats. The essential
and most popular authentication
methods are SPF, DKIM,
and DMARC.
. Emails from such email addresses are generally more secure and probably will be considered reliable.
2. You can send email newsletters to many subscribers. Free domain names like may be blocked for mass mailing. That’s why you need a unique email domain for such purposes.
3. Your emails will stand out in the subscriber’s inbox. That’s because unique email domains usually include a surname, a name of a company, a brand, or a service.
4. Your mail can be corporate. A unique email domain allows you to connect your team members to the domain and make separate email addresses for each of them.
5. There will be no ads. Paid domains don’t place advertisements, so ad banners won’t distract you.

How to Create and Set Up a Domain Email

This algorithm will come in handy if you set up your email domain on paid hosting or some mail service. 

The process consists of 5 steps.

5 main steps of creating email domains.

Step 1. Create a domain

At this step, you should choose an email domain from a variety of available ones. If the domain is not taken, you can use it to create a domain email.

Step 2. Add MX records

A record that shows what mail server will be responsible for accepting emails.  

Step 3. Add an SPF record

This record specifies the mail servers that can send you emails. Such emails won’t go to the spam folder.

Step 4. Add a DKIM record

This record serves as proof that the email was sent by a real person, and not by a spammer or a bot. 

Step 5. Add team members

At this step, you can add your colleagues to the email account. Each of them will get their login and password. 

What Names Can Your Email Domain Have?

The domain name depends on what is important for your company. For example, you want users to remember your email address and search for it online very fast. Or you want crawlers to rank the name of your address high enough to be at the top of search results. 

A domain name can:

  • duplicate the company’s or the brand’s name;
  • align with the company’s activities and the topics of the website;
  • duplicate your first and second names;
  • be an abbreviation (if the company’s name is too long);
  • contain a keyword.

If you’re choosing an email domain for your business, don’t forget about the legal rights to your domain name. 

For example, you need your domain name to match the company’s name. And then you find out that the name has already been taken. In this case, you can challenge the right to this name with the help of your certificate of incorporation. The most important thing here is that the certificate of incorporation should be issued before the domain name registration. 

Summing Up

Acquiring your own email domain is important if you need an email address with a unique domain name. Such an address will come in handy for mass mailing or when you want your emails to avoid getting greylisted or marked as spam. 

You can create a unique email domain on various mail services for a certain fee. You can also pay for hosting and create your email domain there.

After creating an email domain, you should set it up. Mail servers usually give you some tips about this process. If they don’t, here’s what you should do: set up MX, SPF, and DKIM records and add users.
