How to set up email at your own domain

Set up email at your own domain: pick a host (Google Workspace or Microsoft 365), add your domain, create addresses, then add the DNS records.

Quick answer

Setting up email at your own domain means buying or pointing a domain, signing up with an email host like Google Workspace or Microsoft 365, creating addresses such as you@yourbusiness.com, and adding a few DNS records to route and authenticate your mail. Most setups are live within a day.

The phrase “set up your own DNS records” is enough to make most business owners close the tab, which is a shame, because the job behind it is genuinely a one-afternoon, one-time task. Get it right once and every email you send from then on carries your own name instead of Google’s. Here’s the whole thing in plain English.

To set up email at your own domain, sign up with an email host like Google Workspace or Microsoft 365, add your domain and prove you own it, create your addresses, then add the host’s SPF, DKIM and DMARC records to your domain’s DNS. Most setups are live within a day, and a branded address like you@yourbusiness.com looks far more credible than a free Gmail.

What you need before you start

Just two things:

A domain name, the bit after the @ (yourbusiness.com). Got a website? You almost certainly own one. If not, buy one first (what a domain name is).
Access to your DNS settings, usually at your domain registrar or hosting control panel. You’ll paste a few records here.

Domain vs hosting vs email

Three separate things. Your domain is the address, your web hosting runs the website, and your email host runs the mailboxes. They can all be with different companies, they just have to point at each other via DNS.

Choose your email host

For most small businesses it’s two options:

	Google Workspace	Microsoft 365
Best for	Gmail fans, simple needs	Office / Outlook users
Webmail	Gmail interface	Outlook interface
Apps included	Docs, Sheets, Drive	Word, Excel, Teams
Entry price	~£5/user/month	~£5/user/month

Both are reliable, both give you a real mailbox (not just forwarding), and both handle deliverability well. Pick whichever interface your team already knows. Deeper breakdown in Google Workspace vs Microsoft 365.

Skip the free hosting mailbox

Avoid relying on the free mailbox bundled with cheap web hosting. Storage is tiny, spam filtering is weak, and deliverability is often poor, which means your invoices and quotes land in customers’ junk folders.

Set it up, step by step

Start a business plan at Google Workspace or Microsoft 365. During sign-up it asks for your domain name, enter the one you own.

Verify you own the domain

The host gives you a verification record (usually a TXT record). Add it to your DNS to prove the domain's yours. This stops anyone else claiming your email.

Create your addresses

Set up the mailboxes you need, you@, hello@, accounts@. Each named mailbox is one paid user; shared aliases are usually free.

Add the MX records

MX records tell the world where your domain's mail should be delivered. Replace any old MX records with the ones your host provides, or incoming email won't arrive.

Add SPF, DKIM and DMARC

These three prove your mail is genuine and keep it out of spam. Your host supplies the exact values, paste them into DNS.

Send a test email

Email yourself and an outside address, then reply back. Both directions land in the inbox? You're live.

Don’t skip authentication

The single biggest reason domain email fails is missing authentication. SPF, DKIM and DMARC are three DNS records that let receiving servers confirm the mail genuinely came from you. Without them, your messages get flagged, or spoofed by scammers:

SPF, lists which servers are allowed to send for your domain.
DKIM, adds a tamper-proof signature to every message.
DMARC, tells servers what to do if a message fails the first two checks.

Set all three

A mailbox without SPF, DKIM and DMARC is a shop with no lock on the door. Full explanation in SPF, DKIM and DMARC explained.

Move off your free Gmail cleanly

Running the business from a personal Gmail or Hotmail? Migrate properly: set up the new domain mailbox first, import old mail, update your signature and reply-to, then tell customers your new address. Forward the old account to the new one for a few months to catch stragglers. The why is in stop using Gmail for business.

We set all of this up for clients as part of a managed plan, branded mailboxes, correct DNS, and SPF/DKIM/DMARC configured so mail actually reaches inboxes. If you’d rather not touch DNS yourself, see what’s covered on the pricing page or get in touch.

Key takeaway

Email at your own domain is four moves: pick a host, add and verify your domain, create your addresses, add the DNS records (MX plus SPF, DKIM, DMARC). Authentication is the part most people skip, and the part that decides whether your email lands in the inbox or the spam folder.

Once it’s live, send a test both directions, then update your website, social profiles and invoices to the new address. From there, every message you send reinforces your brand instead of someone else’s.

Frequently asked questions

Do I need a new domain to get email at my own domain?

No. If you already own a domain for your website, you can add email to it. You sign up with an email host, prove you own the domain, then add the host's DNS records. No domain yet? Buy one first, usually around £10 to £20 a year.

Can I just forward my domain email to my normal Gmail?

Forwarding works for receiving, but it's a poor long-term setup. Replies still go out from your personal Gmail address, which looks unprofessional, and forwarded mail often fails authentication and lands in spam. A proper mailbox with Google Workspace or Microsoft 365 lets you send AND receive as you@yourbusiness.com cleanly.

How much does it cost?

Expect roughly £5 to £6 per user per month for Google Workspace or Microsoft 365 on their entry plans, billed monthly or annually. No per-email charge. Some web hosts bundle a basic mailbox free, but the dedicated providers are far more reliable for deliverability and storage.

Why do my domain emails go to spam?

Usually because your SPF, DKIM and DMARC records are missing or wrong, so receiving servers can't confirm the mail really came from you. Set all three correctly, warm the address up by sending normally for a few weeks, and avoid spammy subject lines and link-heavy first sends.
