An address such as hello@yourcompany.com immediately tells the recipient which business or brand the message comes from. Instead of using an address provided by a free email service, you can use your own domain after the @ sign.
Setting up a custom-domain email address is easier than it may seem. You need a domain name and an email service that can send and receive messages for that domain. In many cases, email is included with web hosting, but you can also use a separate email provider.
In this guide, you will learn what you need, how the configuration works, which DNS records matter and how to create a professional email address for yourself, your company or your team.
What is an email address with your own domain?
A custom-domain email address uses a domain that you own instead of the domain of a free email service.
For example, if your business website is yourcompany.com, your email addresses could look like:
- hello@yourcompany.com
- sales@yourcompany.com
- support@yourcompany.com
- anna@yourcompany.com
The part after the @ symbol is your domain. Because you control that domain, you can decide which email accounts and aliases should exist within it.
This is particularly useful for companies, freelancers, online stores, agencies and organisations that want their email communication to be consistent with their website and brand.
What do you need to create an email address with your own domain?
Two elements are essential:
- A registered domain name – for example, yourcompany.com. It becomes the part of your email address after the @ symbol.
- An email service – the infrastructure responsible for receiving, storing and sending messages for your domain.
The email service can be part of a web hosting package or a separate service dedicated entirely to business email. You do not necessarily need to host a website in order to use email in your own domain.
Your domain and email service also do not have to be purchased from the same company. If they are provided by different companies, you simply configure the appropriate DNS records so that the domain knows which servers should handle your email.
Choose the right domain name
For a company, the simplest option is usually a domain that matches the business or brand name. A short and easy-to-spell domain also makes the email address easier to remember and reduces the risk of typing mistakes.
You can use a traditional extension such as .com or a country-code domain, but there are also many newer domain extensions associated with particular industries or activities.
Before registering a domain, check whether the name is easy to pronounce, easy to type and unlikely to be confused with another brand.
How to create an email address with your own domain
The exact interface depends on your domain and email provider, but the process usually follows the same pattern.
Register your domain
Start by choosing and registering your domain. The domain does not automatically create an email inbox. It simply gives you control over the internet address that will be used for your website, email and other services.
Choose an email service
Next, choose a service that supports email in your own domain. Check how much mailbox storage is included, how many accounts can be created, whether aliases and forwarding are available and which security features are supported.
It is also worth checking whether the provider supports standard protocols such as IMAP and SMTP. They make it possible to use your mailbox with different email applications.
Configure the MX records
MX records tell other mail servers where messages addressed to your domain should be delivered. Your email provider will give you the exact MX values that should be added to your DNS configuration.
If your domain and email are managed in the same control panel, these settings may be configured automatically. If you use different providers, you may need to enter them manually.
Create your mailbox
Once the domain is connected to the email service, create the mailbox you want to use. You normally choose the part before the @ symbol, set a password and, depending on the service, define the available storage quota.
For example:
- hello@yourcompany.com
- contact@yourcompany.com
- orders@yourcompany.com
- firstname@yourcompany.com
How should you name business email addresses?
For personal business communication, a simple address based on the employee’s name is usually the most convenient. Examples include john@yourcompany.com or john.smith@yourcompany.com.
It is also useful to create functional addresses that remain unchanged when employees change roles.
- hello@ or contact@ for general enquiries,
- sales@ for sales enquiries,
- support@ for customer support,
- billing@ for invoices and payments,
- orders@ for online store communication.
Aliases can also be useful. An alias is an additional email address that forwards messages to an existing mailbox, so you do not always need to create a separate inbox for every address.
Good practice: define one naming convention before creating accounts for a larger team. This prevents situations where some employees use firstname@domain.com while others use firstname.lastname@domain.com without a clear reason.
Configure SPF, DKIM and DMARC
Creating the mailbox is only part of the configuration. Modern email systems also rely on authentication mechanisms that help receiving servers determine whether a message was genuinely sent on behalf of your domain.
The three most important mechanisms are SPF, DKIM and DMARC.
SPF
SPF specifies which servers are authorised to send email on behalf of your domain. If you use several services to send messages – for example, your mailbox provider and a newsletter platform – all legitimate senders need to be taken into account in your SPF configuration.
DKIM
DKIM adds a cryptographic signature to outgoing messages. Receiving servers can verify this signature against a public key stored in your domain’s DNS records.
DMARC
DMARC builds on SPF and DKIM and lets the domain owner define how receiving systems should handle messages that fail authentication. DMARC reports can also help you identify legitimate and unauthorised services sending email using your domain.
Google currently requires senders delivering email to Gmail accounts to use SPF or DKIM. Senders delivering around 5,000 or more messages per day to personal Gmail accounts are subject to additional requirements, including SPF, DKIM and DMARC. Google also recommends configuring all three authentication mechanisms even for smaller senders.
You can find the current requirements in the Gmail Email Sender Guidelines.
Authentication does not guarantee that every email will reach the inbox, because deliverability depends on several factors. However, correct SPF, DKIM and DMARC configuration is now a fundamental part of managing a professional email domain.
Important: do not copy SPF, DKIM or DMARC records from random examples. The correct values depend on the services that actually send email on behalf of your domain.
How can you use your custom-domain email?
You are not limited to your provider’s webmail interface. Depending on the service, you can usually connect the mailbox to desktop and mobile email applications.
Common options include:
- webmail in a browser,
- desktop email applications,
- mobile email applications,
- business collaboration suites,
- CRM and customer support systems.
IMAP is commonly used to synchronise incoming messages and folders across several devices. SMTP is used to send outgoing messages. Your provider should supply the correct server names, ports and security settings.
If you want to migrate from an existing mailbox, check whether your new provider offers IMAP migration or another import method. Before changing MX records, make sure that the new mailboxes already exist. This reduces the risk of messages being delivered to the wrong server during the transition.
Why use an email address with your own domain?
A custom email domain keeps your communication consistent with the rest of your online presence. If customers visit yourcompany.com and receive a message from support@yourcompany.com, the relationship between the website and the sender is easy to understand.
It also gives you more organisational flexibility. As your company grows, you can create addresses for employees, teams and functions without changing the domain used by the organisation.
- Consistent branding – your company name remains visible in every email address.
- Clear identification – recipients can connect the sender with your website or organisation.
- Better account management – you can create, disable and redirect company addresses as your team changes.
- Functional addresses – departments can use addresses such as sales@, support@ or billing@.
- Control over authentication – you can configure SPF, DKIM and DMARC for your own domain.
- Independence from individual employees – company communication does not have to depend on private email accounts.
For a small business, even one mailbox can be enough at the beginning. As the organisation grows, the same domain can support a larger structure of employee accounts, aliases and departmental addresses.
FAQ – Email addresses with your own domain
You need a registered domain and an email service capable of receiving and sending messages for that domain. The email service may be included with web hosting or provided separately.
No. A domain can be used for email even if you do not have a website. You still need an email service and the correct DNS configuration.
No. You can register the domain with one provider and use email from another. You then need to configure the DNS records specified by your email provider.
An MX record tells other mail servers which servers should receive email for your domain. The correct values are provided by your email service.
They are strongly recommended. SPF and DKIM help authenticate outgoing email, while DMARC provides additional policy and reporting mechanisms. Large-volume senders may also be required to use all three by major mailbox providers.
Usually yes. If your provider supports standard protocols such as IMAP and SMTP, you can connect the mailbox to compatible desktop and mobile email applications.
Custom-domain email – summary
To create an address such as hello@yourcompany.com, start with a domain and choose an email service that supports it. Connect the service through DNS, create the required mailboxes and make sure email authentication is configured correctly.
A well-configured custom-domain email gives your company a consistent identity and provides a flexible foundation for communication as your business grows. Remember that the setup should include not only the mailbox itself but also MX records and modern authentication mechanisms such as SPF, DKIM and DMARC.
If you are building your company’s online presence, choose infrastructure that lets you manage your domain, website and business communication in a way that can grow with your organisation.
