How do you set up a professional email address on your own domain?

Why an address on your own domain is worth it

Customers notice the email address on your quote, invoice and website. A free webmail address is not wrong, but an address on your own domain signals that the business is established and that the person writing is part of it. There are practical benefits too:

• It is portable. The address belongs to your domain, not to a mailbox provider. If you switch provider, you keep the address and simply point the domain to the new one.
• It scales. You can create addresses for staff, roles such as invoices@ or bookings@, and remove them when people leave, without losing the business's correspondence.
• It protects your name. With the right records in place, it is much harder for someone else to send email that appears to come from your business.

If you do not have a domain yet, start with our guide to choosing a domain name. Pick one you are happy to see on every email you send.

Your main options

Option	What you get	Worth knowing
Business email suite	Mailboxes plus calendar, contacts and often file storage, from one of the large office software providers	Usually billed per user per month; strong apps and spam filtering
Mailboxes from your web or domain host	Basic mailboxes included with or added to hosting	Often cheaper; quality of spam filtering and webmail varies
Dedicated email provider	Email-focused service, sometimes privacy-focused or European-based	Good middle ground; check data location and app support
Forwarding only	Messages to your domain forward to an existing inbox	Cheap, but replies often still come from the old address unless set up carefully

Prices and plan limits change, so compare each provider's current pricing page. For most small teams the choice comes down to which apps you already use, whether you need shared calendars, and where you want data stored. If you handle sensitive client information, check where the provider stores data and that it offers a data processing agreement under the GDPR.

Choosing your addresses

Decide on a simple scheme and stick to it:

• Personal addresses such as firstname@ for each person who deals with customers.
• Role addresses such as hello@, info@ or bookings@ for the website and printed material. These survive staff changes.
• Aliases rather than extra paid mailboxes for addresses that only need to reach an existing inbox, such as invoices@ landing with the person who handles accounts.

Avoid publishing personal addresses widely if you can use a role address instead. It keeps the business independent of any one person.

The records that make email work, in plain words

Email on your domain is controlled by a few records in your domain's DNS settings, which you edit at your domain registrar or wherever your DNS is hosted. Your email provider tells you exactly what to enter; your job is to understand what each one does, so you can spot problems.

MX records: where your mail is delivered

MX records tell the world which servers receive email for your domain. When you change email provider, these are the records you change. Get them wrong and incoming mail goes missing.

SPF: who may send for you

SPF is a single text record that lists the services allowed to send email using your domain. It usually looks something like v=spf1 include:yourprovider.example ~all. Every service that sends on your behalf needs to be included: your mailbox provider, your newsletter tool, your invoicing software and anything that sends website form notifications. A domain must have only one SPF record; adding a second one, a common mistake, breaks it.

DKIM: a signature on every message

DKIM adds a digital signature to each email you send, which receiving servers check against a public key published in your DNS. If the signature matches, they know the message really came from an authorised sender and was not altered on the way. Each sending service usually gives you its own DKIM record to add.

DMARC: what to do with failures

DMARC tells receiving servers what to do with email that claims to be from your domain but fails SPF and DKIM checks, and where to send reports. Start with a monitoring policy that only collects reports. Once you are sure all your genuine email passes, you can move to a policy that sends failures to spam or rejects them, which makes impersonating your business far harder.

Large mailbox providers increasingly expect senders to have these records in place and may filter or reject mail that lacks them, particularly for bulk sending. Their published sender guidelines describe current expectations.

Setting it up step by step

1. Choose your provider and create the mailboxes and aliases you need.
2. Follow the provider's instructions to verify that you own the domain, usually by adding a record to your DNS.
3. Add or change the MX records. Expect a short delay before changes take effect everywhere.
4. Add the SPF record, merging any existing senders into one record.
5. Add DKIM records for each service that sends email as your domain.
6. Add a DMARC record with a monitoring policy, then review the reports after a few weeks.
7. Send test emails to accounts at different providers and check they arrive in the inbox.
8. Set up the mail apps on your phone and computer, and turn on two-factor authentication for every mailbox.

Common mistakes to avoid

• Forgetting the services that send on your behalf, so invoices or form notifications land in spam.
• Two SPF records, or old entries for providers you no longer use.
• Changing MX records before mailboxes exist at the new provider, losing mail in between.
• Sending newsletters to large lists from a personal mailbox instead of a proper email marketing tool.
• Letting the domain lapse, which stops email and the website at the same moment.
• Weak mailbox passwords. Email is the key to resetting every other account, so protect it first; see our guide to website security basics.

Once your address is set up, use it everywhere: on your website, your listings and your invoices. When you build your site with us, it runs on your own domain, and enquiries from your contact forms are stored as client records in BonusFlow rather than relying only on a notification email reaching your inbox.
