Email on your own domain: why it matters and how to set it up properly
You have a website on your own domain, but you write to clients from a Gmail or Yahoo address. It works, of course. But for a business it is one of those small things that costs more than it seems: in trust, in control and, often, in emails that never arrive.
Why an address on your domain matters
Trust. [email protected] immediately says who you are and matches the website. A generic address, especially an informal one, raises a doubt: is this really the business, or someone pretending to be it?
Control. The address is tied to your domain, which you own. You can change email provider without changing the address, and if a colleague leaves, their mailbox stays with the business rather than in a personal account.
Delivery. With the right records (covered below), receiving mail servers can verify that the email really comes from you. That is what separates a trusted email from one that lands in spam.
Order. You can have addresses by role, such as info@, invoices@, support@, even if they all arrive in the same mailbox.
Privacy and GDPR. If you handle client data by email, you need a provider that offers a data processing agreement (DPA). Business email services provide one; with a personal account it is far less clear.
What you need
- A domain, which you probably already have for the website.
- A business email provider. The most common choices are Google Workspace, Microsoft 365 and Zoho Mail. Some hosting plans include mailboxes. There are free or low-cost plans for small businesses: compare the limits (storage, number of mailboxes, access from Outlook or the phone app).
- Access to your domain’s DNS settings: at your registrar (where you bought the domain) or at a service like Cloudflare, if your DNS is managed there.
The four DNS records to set
Your provider gives you the exact values. What matters is knowing what each one does.
MX: where mail arrives. These tell the world which server receives email for your domain. Without correct MX records, mail does not arrive at all.
SPF: who may send for you. A TXT record listing the servers allowed to send email on behalf of your domain. Careful: there must be only one. Two separate SPF records are a common mistake and break the check.
DKIM: the signature. Your provider signs every email with a key; you publish the public key in DNS so it can be verified. It often has to be switched on in the provider’s admin panel as well as published in DNS: check that it shows as active.
DMARC: what to do with impersonators. It tells receiving servers how to treat email that fails the checks. It’s usually introduced in steps: first only observing, then, once all your own email passes the checks, asking servers to set suspicious messages aside. Moving too fast can send your own email to spam, so it’s worth doing carefully.
Test before you tell your clients
- Send a real email (with a real subject and text, not “test”) to a service such as mail-tester.com: it gives you a score and tells you what is missing.
- Send an email to your own Gmail or Outlook account and check it does not land in spam.
- Set the sender name (for example your business name) and a signature with your name, website and contact details.
If you land in spam at first
That is normal for a domain that has never sent email: the filters do not know it yet. If the technical checks pass:
- ask the people who receive it to mark it “Not spam” and add you to their contacts;
- send real email to real people who reply: it is the strongest signal;
- avoid bulk sending in the first weeks.
Reputation builds over a few weeks of normal use.
A mistake to avoid when you change DNS
If you move your DNS management (for example when you change hosting or move to Cloudflare), copy all the email records across before switching nameservers: MX, SPF, DKIM and DMARC. If one is missing, mail can stop arriving or start landing in spam, and it is often noticed days later.
In short
An address on your own domain, four DNS records set up properly and a few weeks of normal sending: about an hour of work that makes your business look more serious and gets your emails where they need to go.
