Custom Domain Email
What a custom domain email address is
Custom domain email is an address that uses a domain you own, such as [email protected], rather than a shared domain belonging to a free webmail service. The mail is handled by a host you choose, and the address stays yours if that host changes.
A free address ties your identity to the company that runs the service. If you switch providers, your address changes too, and everyone who writes to you must be told. With a custom domain, the address belongs to the domain, and the domain can point to any mail host you pick.
Why businesses choose their own domain
- Trust. Recipients recognise your domain, so your messages are easier to tell apart from lookalike messages sent by others.
- Control. You decide who gets an account, how it is set up and when it is removed. Aliases and shared addresses can be added as the team changes.
- Portability. You can move to a new mail host by updating the mail settings in your domain's DNS. The addresses, and the contacts who use them, stay the same.
- Consistency. Staff addresses, contact forms and invoices all share one domain, which looks professional and is easy to remember.
What a custom domain requires
A custom domain needs three things. First, you must own the domain name through a registrar, which is a separate step from email. Second, you must control its DNS settings, because the mail records there tell other servers where to deliver mail for your domain. Third, you need a mail host that accepts mail for the domain and gives you the records to publish.
Without correct mail records, messages sent to your addresses may bounce or never arrive. The basics of how email services are provided are explained in the guide to email hosting.
A freelancer who changes mail hosts
A freelancer starts with a free webmail address and later moves to an address on their own domain, when clients begin to rely on invoices and project emails. Years later, they switch to a different mail host. Because the address belongs to the domain, clients keep writing to the same address. Only the mail settings in DNS change, and the freelancer's contacts never need updating.
Frequently asked questions
Do I need a custom domain email address?
Not always. A personal or hobby account can work well with a free address. A custom domain matters most for businesses and professionals, and for anyone who wants an address that stays the same if their mail provider changes.
Can I keep my domain email if I change providers?
Usually, yes. Your address is tied to the domain, not to the provider. You move the mailboxes and update the domain's mail records, and the addresses carry on working. Old messages normally need to be migrated separately.
