Business email address: a UK small business guide

Why use a business email address on your own domain?

An address on your domain helps customers connect a message with your business. The name after the @ matches your website, quotation and van. It also lets you keep the same public address if you change email providers later, provided you keep control of the domain.

A free personal inbox can work while you test an idea. Once you put an address on invoices or signs, a domain-based address is easier to keep consistent. It does not prove a sender is honest, and a familiar-looking address can still be forged. Authentication and account security matter too.

If you are setting up the website alongside your email, our managed website service covers the build and ongoing care. Our website design service explains the build itself. Check email requirements with us separately before choosing your mailbox provider.

What do you need before you create the address?

You need a domain registered to you or your company, access to its domain name system (DNS) settings, and an email service. DNS is the set of records that tells other systems where your website and email live. Your website and mailbox can use different providers.

Check who controls the domain before paying for anything. Keep the renewal details and recovery access under the business's control. Our guide to domain name costs and renewals explains the registration side.

Choose addresses people can spell over the phone. For a sole trader, a named inbox plus a hello address may be enough. An alias sends mail to an existing mailbox; it usually has no separate login or storage. A mailbox is an account someone signs into. Ask how your provider charges for each before ordering several.

Which email option suits a small UK business?

Start with how your team already works. A mailbox from your domain or hosting company suits straightforward email. Google Workspace suits people who want Gmail and shared Google documents. Microsoft 365 suits a team that uses Outlook and Microsoft tools. Check the exact plan, because desktop applications are not included in every subscription.

• Domain-host mailbox: compare storage, spam filtering, support, backups and renewal charges. You may already have mailbox capacity in your hosting package.
• Google Workspace: gives you custom-domain email in Gmail with collaboration tools. Each person who needs a separate account normally needs a user subscription.
• Microsoft 365: Business Basic includes professional email and web and mobile apps. Check whether you need the version with Teams and whether desktop Office apps are part of the plan you select.

Decide who needs a private mailbox and who needs access to a shared address such as accounts. Avoid giving several people the same password. Ask the provider how shared mailbox access works on its plan.

How much does a business email address cost in the UK?

Compare the ongoing charge, billing commitment and VAT before introductory discounts. The examples below were checked on 29 October 2026. Domain renewals and any migration work can be separate costs. Prices and promotions can change, so confirm the final terms before ordering.

The Ionos email hosting page showed an email package at £1 a month for 12 months excluding VAT, alongside a standard £2.50 monthly price. It listed five email accounts with 2 gigabytes (GB) each and a free domain. Check the domain's renewal terms as well as the mailbox offer.

The Google Workspace pricing page lists Starter with custom business email and 30 gigabytes (GB) pooled storage per person. From a UK-hosted read, Starter was £5.90 per user per month with a one-year commitment, billed monthly. Check the tax treatment and the flexible monthly price before buying.

The Microsoft 365 Business Basic page showed £5.40 per user per month, paid yearly, excluding VAT, for the version with Teams. Its monthly subscription was £6.48 per user. The annual subscription renews automatically.

For example, two Business Basic users on the annual option cost £10.80 a month equivalent before VAT: two times £5.40. That is £129.60 for a year before VAT, paid yearly. This is an illustration using the quoted price, not a quote for migrating an existing business.

How do you set up the mailbox on your domain?

Choose the provider first, then follow its domain-verification and mail-routing instructions. Create the mailboxes and arrange any old-mail migration before changing the records that receive new messages. A planned change gives you time to test both incoming mail and replies.

1. Confirm the domain is yours and save a copy of the current DNS records.
2. Create the required mailboxes and aliases with your chosen provider.
3. Verify the domain using the exact record the provider supplies.
4. Plan how old messages, contacts and calendars will move.
5. Change the mail exchange (MX) records to the provider's supplied values. MX records tell senders where to send mail.
6. Set up sender authentication, then test incoming mail and replies using an unrelated inbox.
7. Update your website contact details, signatures and devices after testing.

Leave the old service available while you check the migration. DNS changes can take time to reach other systems. Changing MX records does not copy old messages and does not move the website. Keep the old records and an agreed recovery plan in case you need to reverse the routing change.

What do the sender authentication records actually do?

These records help receiving systems check whether mail is authorised to use your domain. These controls identify authorised senders, verify message signatures and publish your policy for mail that fails checks. They reduce spoofing risks; they cannot guarantee inbox delivery.

Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM) and Domain-based Message Authentication, Reporting and Conformance (DMARC) are the full names. The National Cyber Security Centre's email security and anti-spoofing guidance explains how the controls work together. Its implementation sequence starts with monitoring, then moves towards marking and rejecting spoofed messages after legitimate senders have been checked.

• SPF: include every authorised sending service in a single SPF record. That may include your mailbox provider and a service sending your website's messages.
• DKIM: publish the key records your provider supplies and enable signing. A DNS record alone does not switch on signing in every service.
• DMARC: begin with reporting while you identify legitimate sources. A policy of none monitors; it does not ask receivers to reject failing messages. Tighten the policy after checking the reports.

Use the values from your provider rather than copying another company's records. Ask whoever maintains your website to check its enquiry forms before a stricter policy goes on. Forms and invoicing tools can be legitimate senders too.

How do you keep the new email account safe?

Turn on multi-factor authentication, use a unique password and keep recovery details current. Give each person their own login. Sender records protect the domain against some impersonation; they do not stop someone signing into a stolen account or registering a similar-looking domain.

Test a website enquiry all the way through to the right inbox, including the reply. Keep a record of who manages mailboxes, DNS and renewals. When someone leaves, remove their access and arrange who receives future business messages.

Does a Buzzozo managed website include business email?

Our current website plans and inclusions list the website build, green UK hosting, Secure Sockets Layer (SSL), security, monitoring and daily backups. They also list small changes on request within an allowance and a domain in your name. Business email appears under services to ask about, so confirm the mailbox provision and cost with us.

The Website plan is from £149 a month for the first 100 businesses, locked for life. After the first 100, it is from £299 a month. It is monthly, with no contract, and you can cancel any time. The plans page also lists an AI-search-ready build; email hosting is a separate question to settle.

If the website needs doing as well, start with a free 14-day trial, no card needed. Tell us whether you already have a domain and working email so the build keeps your existing contact arrangements in view.
