The domain gives you the address after the @ sign; the host provides inboxes and routes messages. Follow these six steps to set it up without confusing email with a website or changing DNS blindly.
1. Choose or use a domain you control
Choose a domain that represents your business and check whether it is available through a domain registrar. If you already own a domain, you can use it; domain registration and email hosting do not have to come from the same company.

Before proceeding, find out where the domain’s DNS is managed. That is where you will add the verification and mail-routing records requested by your email provider. Registering a domain and setting up email does not, by itself, create a website.

2. Choose an email host
Google Workspace and Microsoft 365 both support email addresses on a custom domain. Choose based on the tools your business already uses and the accounts it needs, rather than assuming one service is best for everyone.
- Google Workspace: consider it if your team already relies on Gmail and Google’s collaboration tools.
- Microsoft 365: consider it if your team already uses Outlook and Microsoft’s collaboration tools.
- For either service: check current plan details, the number of individual mailboxes you need, included features, and whether your domain registrar supports automatic DNS connection or you will need to add records yourself.
Prices, trial terms, provider interfaces, and supported registrar integrations can change. Confirm them on the provider’s current signup and setup pages before choosing.
3. Add and verify your domain
Enter your domain in the provider’s email or admin setup. The provider must confirm that you control it before it can be used for the service. A common method is adding a unique TXT record supplied by the provider to your domain’s DNS.
Google’s setup instructions describe adding a verification code at the domain host. Microsoft documents DNS-based verification and, in some circumstances, verification using a website file. Microsoft’s Domain Connect flow can add records automatically when used with a supported registrar. Follow the method shown in your own admin setup; do not substitute a verification value from another domain or account.

4. Create individual mailboxes and shared addresses
Create a mailbox for each person who needs an individual sign-in, such as [email protected]. Then decide how to handle role-based addresses such as sales@ or support@. Depending on the provider, these may be configured as aliases or groups rather than separate user mailboxes.
Google says aliases are included without counting as users on the offering described in its setup guidance. Plan terms can change, so confirm how aliases, groups, and user accounts are treated on the plan you select.
5. Route incoming mail with DNS
Add the mail records requested by your provider at the authoritative DNS host—the service that currently manages your domain’s DNS. MX records tell other mail systems where to deliver incoming messages. The provider may also request other records for email or related services. Use the exact values displayed in the provider’s current setup wizard, not generic values copied from an old guide.
If the domain already receives email, plan the change before replacing its MX records. Microsoft advises creating users and mailboxes before adding an MX record when setting up its service. Incorrect DNS records can cause email and service outages, as Microsoft warns in its custom-domain setup guidance. Keep track of existing records and follow the provider’s sequence so you do not redirect mail before the destination inboxes are ready.
6. Configure authentication and test delivery
Use your provider’s instructions to configure SPF and DKIM, then publish a DMARC policy appropriate to the business. These email-authentication settings use DNS records and must account for the systems that send mail using your domain. Google recommends SPF and also recommends DKIM and DMARC.
Best Value
Do not tighten a DMARC policy until you understand which services send mail for your domain; a policy that does not account for a legitimate sender can affect delivery. After setup, test the system:
- Send a message from each new mailbox to an external email account.
- Reply from that external account and confirm the reply arrives in the correct inbox.
- Test role-based addresses and confirm aliases or groups reach the intended people.
- Check that expected messages arrive and that outbound test messages are not rejected or treated as suspicious by the recipient.
What the setup gives you—and what it does not
A custom-domain address gives your business email on a domain it controls, with a hosted service handling mailboxes and delivery. It does not automatically provide a website, and getting an address alone does not establish a complete business identity. Keep domain ownership, email hosting, mailbox setup, and any website as separate decisions even when one company offers more than one of them.
