What Is an Email Domain and How to Register One?

An email domain, typically the part of an email address following the “@” symbol, denotes the organization or company owning the address. This article explores what email domains are and guides readers on how to register one.

While personal email domains like gmail.com or yahoo.com are common, companies use their branded domains, such as companyname.com, for professional communication, which helps to build recognition and trust.

  • Explore various web hosting services that provide email domain registration
  • Discover ways to secure a free email domain, a cost-effective option for your business

What Is an Email Domain Name?

An email domain name is the part of an email address that comes after the “@” symbol. It specifies the mail server that is responsible for receiving and delivering emails for that address.

For instance, in the email address “john.doe@example.com”:

“john.doe” is the local part or the username.

“example.com” is the email domain name.


Having a custom email domain often conveys a sense of professionalism and can help in branding, as it indicates that the entity has a dedicated domain and possibly a website associated with it.

Different Parts of an Email Domain Name

In understanding an email domain name, it’s vital to dissect its components: the symbols that separate them, the username that identifies you, and the top-level domain (TLD) that brings it all together.

In the following sections, we’ll delve deeper into these elements to demystify the intricacies of email domains.

Email Domain Symbol

The “@” symbol is the keystone of any email address, serving as a separator between the username and the email domain. This symbol signifies the user’s intention to send their message to a specific domain.

Username in an Email Address

The username in an email address comes before the “@” symbol and identifies the specific recipient. It’s often based on the user’s real name to maintain professionalism and avoid junk folders. Numbers, punctuation, and symbols should be used sparingly, with a focus on keeping professional and personal email accounts separate.

Top-Level Domain Name in an Email Address

The top-level domain name (TLD) follows the period in an email address (e.g., .com, .org). It specifies the type or category of the domain, such as commercial, organizational, or educational, and is essential for domain identification.

Email Domain Examples

Email addresses typically comprise two main parts: the username and the email domain. Let’s break down some examples:

  • First Name and Last Name: In an email like jsmith@yourbusiness.com, “jsmith” is the username, representing the individual using the email account, and “yourbusiness.com” is the email domain, signifying the organization or domain owner.

Example of email address:  jsmith@yourbusiness.com

  • Incorporating a Title: You might also come across emails like john.cpa@yourbusiness.com. In this case, “john.cpa” is the username, indicating both the person’s name and their title or profession, while “yourbusiness.com” remains the email domain.

Example of email address:  john.cpa@yourbusiness.com

Understanding these components helps you identify the sender or recipient of an email and the organization it’s associated with.

What Is a Custom Email Domain?

A custom email domain is a unique and branded domain name that a business or organization uses to create personalized email addresses.

Instead of relying on generic email providers’ domains, such as “@gmail.com” or “@yahoo.com,” a custom email domain enables companies to use email addresses like “user@yourdomain.com.”

This not only enhances professionalism but also strengthens brand identity, making your emails more recognizable and trustworthy.

What Is a Custom Email Domain Used for?

A custom email domain is primarily used to bolster a company’s brand identity and professionalism. It ensures that email addresses match the business’s website domain (e.g., user@yourdomain.com), enhancing trust and recognition.

Additionally, custom email domains allow businesses to maintain control, privacy, and security over their communication channels.

Benefits of Owning a Custom Email Domain

Your email domain helps you shape your online identity and professional reputation. Here, we explore the compelling benefits of owning a custom email domain, highlighting its crucial role in simplifying communication, enhancing credibility, asserting industry leadership, maintaining brand consistency, and enabling personalization.

  • Simplicity: A custom domain email address streamlines communication, making it straightforward for people to reach you. Your email address matches your brand’s domain, eliminating confusion.
  • Credibility: Businesses with custom email addresses appear more professional and reliable. It instills confidence in potential clients, customers, and partners.
  • Leadership: A custom email domain showcases your leadership within the industry. It reinforces your brand’s authority, enhancing your market presence.
  • Consistency: A unified brand image is maintained across your website and email communication. This consistency bolsters brand recognition and trust.
  • Personalization: Custom email domains offer the flexibility to create personalized email addresses, further enhancing your branding and client engagement.

How to Register Your Own Email Domain Name

When it comes to registering your own email domain name, you have two primary avenues to explore. You can either set up a custom email domain with your hosting provider or establish a unique domain within Google Workspace.

Option 1: Create Your Own Email Domain with Your Hosting Provider

One way to secure your custom email domain is by working with your hosting provider. This option typically lets you link your email domain directly to your website’s hosting. In the following steps, we’ll guide you through the process of creating your custom email domain with your hosting provider.

1. Choose a Hosting/Domain Provider

Several hosting companies, such as Bluehost, Hostinger, and DreamHost, offer email hosting services bundled with custom domain registration. Similar to website hosting, these providers manage email hosting on servers.

When selecting a hosting or domain provider, evaluate the features included in their plans. Pay attention to factors like mailbox quantity and storage space per mailbox to ensure you won’t need to delete crucial messages.

2. Use an Email Domain Checker to Check for Domain Availability

To select an email domain name, align it with your company or website name. Utilize email domain checkers to ensure availability.

Here are some options:

WhatsMyDNS.net: Verify DNS records and domain availability globally.

These tools help you secure an email domain that matches your brand or website name.

3. Register an Available Email Domain

Completing your purchase by providing your payment details on the checkout page will register your selected email domain. Following payment, your hosting provider’s instructions will guide you in creating new email addresses.

With your custom email domain, you can build your email list, integrate it with your chosen email marketing platform, and send emails to subscribers interested in your products and services.

Option 2: Create a Custom Domain with Google Workspace

Google Workspace offers a straightforward solution. For just $7.80 per user per month, you can acquire custom email addresses like joe@yourcompany, signaling professionalism and reliability.

Google ensures 99.9% uptime and provides robust security, spam protection, and data backups to safeguard your business information.

  1. Sign Up for Google Workspace

When enrolling in Google Workspace, designate the domain you desire for your business email. If you don’t already own the domain, Google offers the option to purchase it, ensuring a seamless registration process.

  1. Set Up Your Account

As you set up your account, you’ll receive prompts to verify your domain. Enhance your account’s personalization by uploading your company logo, establishing custom email aliases (e.g., marketing@yourcompany), and configuring email addresses for additional users.

  1. Start Sending Emails

Start your email communication with Google Workspace, which offers a 14-day free trial. During this period, you can seamlessly send emails, conduct high-definition video conference calls, collaborate on document creation, and share files in the cloud. Should you wish to continue using Google Workspace after the free trial, you can set up billing at any time.

How To Choose an Email Domain Provider

Selecting the right email domain provider is crucial in a world where email communication continues to soar.

In 2023, the daily global email traffic is a staggering 347.3 billion emails, marking a 4.3% increase from the previous year. These numbers are projected to climb even higher in 2024, reaching 361.6 billion emails daily.

To put it in perspective, the average office worker sends about 40 emails daily. However, what’s even more astonishing is that the average person receives a whopping 121 business-related emails daily. Given the volume of emails exchanged, having a dependable email domain provider is imperative.

Below, we’ll tell you what to look for.

Customer Support

When selecting an email domain provider for your business, don’t overlook the importance of customer support. Robust features are valuable, but compliance with privacy and data management regulations is equally critical. It indicates the provider’s commitment to security and reliability rather than just empty marketing claims.

For instance, if your team handles sensitive health data, ensuring HIPAA compliance is paramount. Similarly, if your user base includes individuals in Europe, adhering to GDPR privacy laws is essential. Neglecting these regulatory requirements can lead to legal consequences and potential damage to your company’s reputation.

External compliance safeguards your operations, while robust customer support is an internal safety net. If issues arise with your email provider, you need the assurance that your concerns will be addressed promptly by responsive and knowledgeable support teams.

Here are key factors to consider:

  • Evaluate the quality of customer support, including accessibility to real people
  • Check if the provider offers options that align with HIPAA and GDPR compliance requirements

Cost Effectiveness

The cost-effectiveness of a custom email domain can vary significantly, with monthly user license fees ranging from $0 to $18 or more.

Pricing depends on various factors such as storage capacity, attachment size limits, and additional features like security and analytics offered by your selected email hosting service. It’s crucial to find a provider that aligns with your budget and requirements.

Capabilities and Compatibilities

When evaluating an email domain provider for your business, consider the capabilities and compatibilities it offers to ensure smooth integration into your team’s workflow. Employees often have varying levels of tech-savviness, so opting for a user-friendly provider is crucial.

Look for the following:

  • User interface: An intuitive interface eases adoption and onboarding.
  • Desktop apps: Check compatibility with existing desktop clients (e.g., Outlook, Apple Mail).
  • Mobile apps: Ensure mobility for agile and remote teams.
  • Integration with IMAP/SMTP: Compatibility with clients like Outlook or Thunderbird.

Additionally, assess these key points:

  • Support for the number of email users you need
  • User-friendly interface
  • Availability on employees’ devices
  • Cross-platform and email client compatibility
  • Email sending limitations


When choosing an email domain provider, consider their coverage.

Ensure the provider offers services that align with your geographical and global needs. Coverage encompasses factors like regional data centers, accessibility in various countries, and support for remote teams. Make sure the provider’s reach matches your business’s geographical footprint.

Provider Reputation

Look for reviews, customer testimonials, and feedback on the provider’s services. Explore how long the provider has been in the industry and whether they have a track record of reliable and secure services. A reputable provider is more likely to deliver the quality and security your business requires.

Final Word

For example, if your email is “johndoe@yourcompany.com,” the email domain is “yourcompany.com.” It’s the unique identifier that shows the origin of your email address, whether it’s a personal or business domain.

Do I need a domain for an email address?

Yes, you need a domain to create a custom email address. The domain is the unique part that comes after the “@” symbol in an email address, like “@yourcompany.com.” It indicates the source of your email, whether for personal or business use. Registering a domain is crucial for branding and professionalism, allowing you to have personalized email addresses connected to your website or organization.

What is an email domain for Outlook?

An email domain for Outlook typically refers to the domain name used in email addresses associated with Microsoft Outlook. It helps users establish credibility by using a custom domain that matches their organization or brand.

For instance, “yourname@yourcompany.com.” This personalized email address enhances professionalism and trustworthiness when communicating through Outlook, which is essential for personal and business use.

How do you create your own email domain for free?

To create an email domain of your own for free, use a free domain provider that offers email hosting. Register a domain with a free provider, ensuring it matches the same domain you intend to use for your email addresses.

Many hosting companies, like Zoho, offer free email hosting services when you purchase or use their free domains, allowing you to create custom email addresses without additional cost.

How can you configure an email on a different host from the website?

To configure email on a different host from the website, first access your domain’s DNS settings. Modify the MX (Mail Exchange) records to point to your email host’s servers instead of your web host’s. Ensure your email host provides you with the necessary server and port information, and set up your email client or software with these details. This way, email functions separately from your website hosting.

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

A domain name is the web address that identifies a website, like “example.com.” An email domain, on the other hand, refers to the part of an email address that comes after the “@” symbol, specifying the domain used for email communication. While a domain name is primarily used for a website’s online identity, an email domain is exclusively for managing email addresses associated with that domain.

Several web hosting providers offer free email domain services with their hosting plans. Some popular options include Bluehost, HostGator, and Hostinger. These providers allow you to create custom email addresses using your domain name as part of their hosting packages. While these email services are often included, it’s important to review the features, limitations, and associated costs before choosing a hosting provider.

Can I create multiple email addresses with my email domain name provider?
