Understanding and Setting Up a Custom Email Domain

A custom email domain means your email address uses your own website’s domain name, for example, jane@smithaccountants.co.uk, rather than a generic domain like Gmail.com. Using a custom domain makes your business look more professional and trustworthy to clients. This guide covers why small businesses seek custom email domains, a step-by-step setup process, common errors to avoid, and how HelloGrowthCRM can support your email management.

Why this comes up / what goes wrong

Many small business owners in the UK start with personal email accounts like Gmail or Outlook for their business communications. While these are easy and free, they often look unprofessional and can reduce customer confidence. For example, a client receiving a quote from jane.smith@gmail.com may question the legitimacy of the business.

Additionally, managing sales and customer communications across personal email accounts, WhatsApp, and spreadsheets can cause lost leads and slow responses. Business owners want a consistent, branded email address linked to their website domain to improve credibility and make follow-up easier.

Step-by-step

1. Choose and register your domain name: Pick a domain that matches your business name or brand, such as smithaccountants.co.uk. Use a UK domain registrar like 123 Reg or GoDaddy. Check availability and purchase the domain.

1. Select an email hosting provider: Many domain registrars offer email hosting, or you can choose dedicated services like Microsoft 365 or Google Workspace. (learn.microsoft.com) Confirm that the provider supports custom domain email addresses.

1. Set up DNS records: Log in to your domain registrar’s control panel and add MX (Mail Exchange) records as instructed by your email hosting provider. This directs emails to your hosting service.

1. Create your email accounts: Within your email hosting dashboard, create the email addresses you need, such as info@smithaccountants.co.uk or jane@smithaccountants.co.uk.

1. Configure your email client: Set up your email accounts on your preferred email clients or devices using the server settings provided.

1. Test sending and receiving: Send test emails to and from your new custom domain email to ensure everything works correctly.

1. Update your business contacts and marketing materials: Replace old email addresses with your new custom domain email on your website, business cards, and social media.

1. Consider integrating with CRM tools: Use platforms like HelloGrowthCRM to manage your emails, sequences, and customer follow-up efficiently.

Example (fictional figures)

Smith & Co Accountants, a small practice in Birmingham, decides to set up a custom email domain on 10/04/2026.

• Domain registration: £15 per year
• Email hosting (Microsoft 365 Business Basic): £4.50 per user per month
• They create 3 email accounts: info@smithaccountants.co.uk, jane@smithaccountants.co.uk, support@smithaccountants.co.uk

Annual hosting cost calculation: £4.50 × 3 users = £13.50 per month £13.50 × 12 months = £162 per year

Total first-year cost: £15 (domain) + £162 (hosting) = £177

This investment gives Smith & Co a professional email presence and improves client trust.

Common mistakes

• Using a domain name that is hard to spell or remember: Choose a simple, clear domain to avoid losing emails or customers.
• Skipping DNS setup or entering incorrect MX records: Follow instructions carefully to ensure emails route properly.
• Not testing email functionality before switching: Always test sending and receiving to avoid downtime.
• Continuing to use old email addresses publicly: Update all business materials to avoid confusion.
• Ignoring email management tools: Without a CRM or shared inbox, emails can get lost or delayed. Use tools like HelloGrowthCRM for better tracking.
• Not securing your email accounts: Use strong passwords and enable two-factor authentication where possible.
