Setting up a professional custom email address such as hello@yourbrand.co.uk gives your UK e-commerce business a credible appearance and helps separate business communication from personal accounts. It reinforces your brand name every time you send or receive messages.
This guide explains the main options, how to configure DNS records, improve email deliverability, maintain consistent branding and connect everything smoothly with a Shopify store. The steps are designed for early-stage founders who want practical results without unnecessary complexity.
Choosing the right email provider
Most UK founders begin with one of three routes: a dedicated email hosting service, a Google Workspace account, or Microsoft 365. Each has different strengths for e-commerce sellers.
Google Workspace provides a familiar interface, 30 GB of storage per user on the entry plan and easy integration with other Google tools. Microsoft 365 offers Outlook, calendar sharing and desktop apps that some sellers prefer. Dedicated providers such as Zoho Mail, MXRoute or Proton Business give lower-cost options with strong privacy features.
Compare current storage, number of email addresses allowed and spam filtering before choosing. Many services include a free trial period so you can test deliverability with your customer base. Select a provider that can grow with your order volume and team size.
Registering and verifying your domain
Before creating email addresses you must own the domain name. If you have not already registered your .co.uk or .com through a registrar such as 123-Reg, GoDaddy or Namecheap, complete this first. Choose a registrar that offers easy DNS management.
After purchase, verify domain ownership with the email provider. This usually involves adding a TXT record or clicking a verification link sent to the administrative contact. Verification normally takes a few minutes but can occasionally require 24 hours to propagate.
Keep registrar login details secure. You will return to this account to edit DNS records in the next stage.
Configuring DNS records for email
Email routing depends on correct DNS settings. The most important record is the MX record, which tells the internet which server should receive mail for your domain.
Log into your domain registrar and locate the DNS management section. Delete any existing MX records that point to the wrong provider. Add the new MX records supplied by your chosen email service. Common values include priority numbers such as 1, 5 or 10; lower numbers are tried first.
Additional records improve reliability. Add an SPF record (TXT type) to authorise sending servers and reduce spoofing. A DKIM record allows cryptographic signing of outgoing messages. DMARC records tell receiving servers what to do with mail that fails SPF or DKIM checks. Start with a basic SPF record listing your provider and your web server if you send transactional mail from Shopify. Update these records whenever you change providers.
Propagation usually completes within one to four hours but can take up to 48 hours in rare cases. Use online DNS lookup tools to confirm the new records are live before sending test emails.
Improving email deliverability
Even with perfect DNS records, emails can land in spam folders. Deliverability depends on sender reputation, content and recipient behaviour.
Warm up a new domain gradually. Begin by sending a small number of emails to known contacts and monitor bounce rates. Increase volume slowly over several weeks. Avoid sudden large mailings that trigger spam filters.
Use a consistent from-name that matches your brand. Keep subject lines clear and relevant to the order or enquiry. Provide an obvious unsubscribe link in marketing messages to comply with UK regulations.
Monitor reputation through free tools such as Google Postmaster Tools or Microsoft SNDS. Check bounce and complaint rates inside your email provider dashboard. If rates rise, investigate content, remove inactive addresses and consider using a dedicated transactional email service for order confirmations.
Separate marketing and transactional email streams where possible. Many Shopify users route order notifications through the platform’s own SMTP settings or a specialist service while using their custom domain for general correspondence.
Branding your email addresses and signatures
Consistent branding builds trust. Create addresses that reflect roles or departments: orders@yourbrand.co.uk, hello@yourbrand.co.uk, accounts@yourbrand.co.uk. Avoid generic names that may become confusing if team members change.
Set up professional email signatures that include your full name, job title, business telephone number, website address and a small logo if the provider allows. Add links to your latest product collection or shipping policy when relevant.
Use the same colour scheme and fonts that appear on your Shopify store. This visual consistency reassures customers that they are dealing with the same legitimate business across all touchpoints.
Consider adding a short legal disclaimer at the bottom of external emails if you discuss contracts or pricing, but keep it concise. Review signatures every six months to ensure contact details remain current.
Integrating custom email with Shopify
Shopify allows you to send transactional emails from your own domain rather than the default @shopify.com addresses. In your Shopify admin, go to Settings then Notifications. Under the Email section you can configure a custom SMTP server or use the built-in sender domain feature.
For full branding, add your domain in the Sender email address field and follow Shopify’s verification steps. This usually requires adding a CNAME record supplied by Shopify to your DNS settings. Once verified, order confirmations, shipping notifications and abandoned cart emails appear to come from your brand.
If you prefer more control, configure SMTP details from your email provider directly in Shopify. Enter the hostname, port (commonly 587), username and password. Test the connection with a sample order notification. Some sellers route only transactional mail through Shopify and keep general enquiries in their main inbox.
Check that the from address matches your verified domain to avoid authentication warnings. Review the design of Shopify email templates so they match the style of your website. Small changes to colours, fonts and logo placement create a seamless experience.
Maintaining and scaling your email setup
Schedule regular checks of DNS records, especially after changing hosting or website platforms. Renew your domain and email service subscriptions before they expire to prevent delivery failures.
As your e-commerce business grows, add team inboxes or shared addresses using distribution groups or aliases. Most providers allow simple forwarding rules that direct mail to the right person without exposing multiple addresses externally.
Back up important messages periodically. Consider archiving older correspondence to keep your active inbox manageable. If you move to a larger team, evaluate whether a more advanced business email plan better suits your needs.

Frequently asked questions
How long does it take for custom email DNS changes to take effect?
DNS changes for MX, SPF and other records typically propagate within one to four hours. In some cases it can take up to 48 hours for all internet providers to update their caches. Use online lookup tools to confirm records are live before sending important emails.
Can I use my custom domain with Shopify transactional emails?
Yes. Shopify allows you to verify and use your own domain for order confirmations and notifications. This is done through the Notifications settings by adding a CNAME record and completing domain verification. It removes the default Shopify branding from customer emails.
What is the difference between Google Workspace and dedicated email hosting?
Google Workspace offers familiar Gmail with calendar and document tools but at a monthly cost per user. Dedicated providers often provide lower prices, more storage options or stronger privacy features. Choose based on the tools you already use and the volume of email your e-commerce brand expects to send.
Do I need DKIM and DMARC records for my e-commerce emails?
SPF is the minimum requirement to improve deliverability. Adding DKIM signs your messages cryptographically and DMARC tells receivers how to handle failures. Most professional setups include all three to reduce the chance of legitimate emails landing in spam folders.
Should I separate marketing emails from order confirmation emails?
Separating the two streams is recommended. Transactional emails such as order receipts benefit from high deliverability and should come from your verified domain. Marketing campaigns can be sent through specialist platforms that handle subscriber lists and compliance more easily.
