A professional email address uses your business domain, such as hello@yourbusiness.co.uk or accounts@yourbusiness.com, instead of a general personal address.
It gives customers a clear way to recognise your business and makes it easier to organise messages as your business grows. But using your domain for email involves more than choosing an address. You also need to decide where messages will be stored, connect your domain to an email provider and protect the setup with the right security controls.
This guide explains the main choices in plain English.
What is a domain email address?
A domain email address is an address that uses the domain name belonging to your business. For example:
hello@oakstreetbakes.co.ukbookings@northshorefitness.comaccounts@greenfieldrepairs.co.uk
The part after the @ symbol is your domain. The part before it identifies a person, team or purpose.
This is different from using an address provided by a general email service. A personal address may still work well for private communication, but a domain-based address is usually more suitable for customer enquiries, invoices, bookings and website contact forms.
A custom domain does not guarantee that every message will be delivered or prevent phishing. It is one part of a professional setup, alongside a suitable email provider, accurate DNS configuration and good account security.
Choose between a mailbox, forwarding and aliases
Before changing any settings, decide what you actually need. The terms can sound similar, but they describe different things.
A full mailbox
A mailbox is a complete email account. It stores messages and normally lets you send and receive email through a webmail service, desktop application or phone app.
For example, sam@yourbusiness.com could be a mailbox used by the business owner. It would have its own password, inbox, sent items and account settings.
A full mailbox is usually the right choice when you need to:
- Send replies from your domain address
- Keep a history of conversations
- Use email on several devices
- Give a staff member their own login
- Manage calendars, contacts or other provider features
Email forwarding
Forwarding sends messages received at one address to another inbox. For example, messages sent to hello@yourbusiness.com might be forwarded to an existing personal or work inbox.
Forwarding can be a simple and low-cost way to receive enquiries, especially for a sole trader or a new business. However, forwarding alone may not give you a proper mailbox, and sending replies from the domain address can require additional configuration. Some forwarding services also have limitations around filtering, storage and message handling.
Check exactly what a forwarding service supports before relying on it for important business communication.
An alias
An alias is an additional address that points to an existing mailbox rather than creating a separate inbox. For example, bookings@yourbusiness.com and hello@yourbusiness.com might both deliver to the same mailbox.
Aliases are useful when one person or team handles several types of enquiry. They can make your business look organised without creating unnecessary accounts and subscriptions.
An alias is not always a separate login. If several people need access, a shared mailbox or separate user accounts may be more appropriate, depending on your provider and working arrangements.
Choose practical addresses
Start with the addresses customers are most likely to use. Common examples include:
hello@for general enquiriesinfo@for general informationbookings@for appointments or reservationssales@for product or service enquiriesaccounts@for invoices and finance matterssupport@for customer assistance
You do not need a separate mailbox for every address. If the same person handles all enquiries, aliases or forwarding may be enough. Create separate mailboxes when different people need their own access, when messages need to be kept separate or when a team needs a shared working process.
It is also sensible to create a personal address for each staff member who needs to send and receive business email. Avoid sharing one password between several people where possible.
Website hosting and email hosting are different
Your website and your email can use the same domain while being provided by different services.
Website hosting stores the files and systems needed to display your website. Email hosting stores mailboxes and handles sending and receiving messages. A domain registrar may provide one, both or neither, depending on the package.
This means moving your website does not necessarily mean moving your email. Likewise, changing your email provider does not automatically require moving your website.
Before buying a service or changing providers, check:
- Whether email hosting is included
- How many mailboxes or users are included
- Whether forwarding and aliases are supported
- How much mailbox storage is available
- Whether multifactor authentication is available
- How support handles setup and account recovery
Do not assume that a website hosting plan includes a complete email service. Confirm what is included and where your existing mail is currently stored.
A safe setup process
The exact screens differ between providers, but the overall process is usually similar.
1. Choose an email provider
Choose a provider that fits the way you work. Consider the number of users, the devices you use, storage needs, shared addresses and the level of support available.
If you already have important email, check whether the provider can help transfer old messages. Keep access to the old mailbox during a planned transition wherever possible. It gives you time to find missing messages, update devices and correct problems before closing anything.
2. Add your domain to the provider
The provider will normally ask you to confirm that you control the domain. This may involve adding a temporary DNS record or following another verification step.
DNS, or the Domain Name System, is the part of your domain setup that tells the internet where services such as your website and email should go.
3. Add the required DNS records
Your provider will give you records to add to your domain’s DNS settings. These may include mail delivery records and authentication records.
Changing DNS records can affect email, your website or other services, so make changes carefully. Do not copy generic records from an unrelated guide. Use the provider’s current instructions, and ask for help if you are unsure which records are already in use.
4. Create mailboxes and aliases
Set up the main user accounts, shared addresses and aliases you decided on earlier. Use clear names and document who has access to each address.
5. Test sending and receiving
Send test messages to and from an external address. Check that replies come from the intended address and that messages arrive in the right mailbox or folder.
Also test your website contact forms after changing email settings. A form can appear to submit successfully while notifications are sent to an old or incorrect address. Check the form’s recipient address, reply-to behaviour and any automated confirmation messages.
Finally, test the setup on the phones, tablets and computers your team uses.
SPF, DKIM and DMARC in plain English
Email providers use several DNS-based checks to help identify messages that are allowed to use your domain. Three common terms are SPF, DKIM and DMARC.
- SPF lists the services that are permitted to send email for your domain.
- DKIM adds a digital signature to outgoing messages so the receiving service can check that the message was authorised and has not been changed in transit.
- DMARC gives receiving services instructions for handling messages that appear not to pass these checks. It can also provide reports about activity involving your domain.
Together, these settings can help receiving services distinguish legitimate messages from some unauthorised ones. They are not a guarantee against spoofing, phishing or delivery problems, and they do not replace sensible security practices.
Follow your email provider’s instructions carefully. The correct records depend on which services send email for your domain, including website forms, newsletters, customer management systems or invoicing tools. Adding a record without understanding what it does can interfere with legitimate sending.
Protect your email accounts
Business email often contains customer details, invoices, contracts and access links. Protect it as carefully as you would other business systems.
Use a unique, strong password for every mailbox or user account. Enable multifactor authentication, which requires an additional verification step beyond the password, wherever the provider supports it.
Keep recovery email addresses and phone numbers up to date, but make sure they are controlled by the business rather than belonging only to one person. Review account access regularly, especially when someone joins or leaves the business. Remove or suspend access promptly when a staff member leaves, and check shared mailboxes, forwarding rules and connected devices.
Be cautious with unexpected requests to change bank details, passwords or payment instructions. A familiar-looking sender address is not proof that a message is genuine.
Checklist before switching providers
Before cancelling an old service or changing important DNS settings, check that you have:
- Chosen the right mailbox, forwarding and alias arrangement
- Confirmed what your email provider includes
- Recorded your existing addresses and forwarding rules
- Kept access to the old mailbox during the transition
- Backed up or transferred important messages where appropriate
- Added the provider’s required DNS records carefully
- Tested incoming and outgoing email from an external account
- Tested website contact forms and automated notifications
- Updated phones, computers and email applications
- Enabled multifactor authentication
- Reviewed recovery details and staff access
A little planning can prevent missed enquiries and confusing downtime.
