Booking confirmations from a generic address look amateur. Your own domain builds trust and keeps your emails out of spam.
A guest books your holiday home and receives a booking confirmation from a generic Gmail address. The same guest then checks in at a hotel and receives a confirmation from the hotel reservations team at their own domain.
The functional content might be identical, but the signals are entirely different. One says individual with a property. The other says professional hospitality business. Guests notice, even when they do not consciously articulate it.
In an industry where guests increasingly compare holiday rentals to hotels in terms of experience expectations, professionalism in your communications matters more than it used to.
A custom email domain means sending email from an address at your own domain name — hello at yourbrand.co.uk or reservations at yourproperty.co.uk — rather than from a free email service.
This is different from having a website (you can have a custom email without a website, though you will usually want both), running your own email server (modern email uses cloud services like Mailgun or Google Workspace; you own the domain but a professional service sends the email), and buying expensive business email (a custom domain and professional email sending can cost less than £15 per year).
Beyond brand perception, custom email domains with proper technical configuration significantly improve email deliverability. Emails sent at high volume from free email services are frequently flagged as spam or promotional. Emails from a custom domain with SPF, DKIM, and DMARC records correctly configured are treated as legitimate business communications.
For a holiday rental host, deliverability matters on every single guest touchpoint: booking confirmations that guests need to find their access code, pre-arrival messages with check-in instructions, post-stay review requests, and re-engagement emails to past guests. If these go to spam, you are not just missing a marketing opportunity — you are creating operational problems that affect the quality of stays.
LetPilot integrates with Mailgun to provide professional email sending from your own domain. The setup process is straightforward.
Register a domain name if you do not already have one. In LetPilot settings, navigate to Email Domain and add your domain. LetPilot provisions a Mailgun sending domain and generates the required DNS records. Add the DNS records to your domain DNS settings — LetPilot provides step-by-step instructions appropriate for the most common domain registrars. LetPilot verifies the records and activates sending.
From this point, all guest emails sent through LetPilot arrive from your branded domain — booking confirmations, check-in guides, automated pre-arrival messages, and any manual messages you send to guests.
For domain choice: your property name (thelakeviewcottage.co.uk) works well for a single property or a small portfolio with strong brand around a specific property. Your management business name (lakeshoreproperties.co.uk) works better if you manage multiple properties under a consistent brand. Location-based domains can have SEO benefits if they match what guests search for, though they limit flexibility as you grow.
For address choice: hello at yourdomain.com is friendly and generic. reservations at yourdomain.com is professional and hospitality-focused. stay at yourdomain.com is memorable. Avoid using your personal name for transactional communications — it can create confusion when team members or business arrangements change.
These three DNS records are what make professional email deliverability work, and understanding what they do helps explain why they matter.
SPF (Sender Policy Framework) tells receiving mail servers which services are authorised to send email on behalf of your domain. Without it, emails from your domain are treated with suspicion by spam filters.
DKIM (DomainKeys Identified Mail) cryptographically signs your emails so receiving servers can verify they genuinely came from your sending provider. This is the strongest individual signal of email legitimacy to modern spam filters.
DMARC (Domain-based Message Authentication, Reporting and Conformance) tells receiving servers what to do with emails that fail SPF or DKIM checks, and gives you reporting on any attempts to send email impersonating your domain.
LetPilot Mailgun integration configures all three automatically. You add the DNS records LetPilot generates, and the authentication is handled for you. You do not need to understand the technical details in depth — you just need to add the records your domain registrar presents.
Once your email domain is set up, apply it consistently across all guest communications through LetPilot, your own personal emails to guests, any marketing emails to past guests, your Google Business Profile contact email, and your website contact information.
Consistency builds brand recognition and trust. A guest who receives an email from your branded domain, sees that same domain on your website, and can find it in your Google listing is experiencing a coherent, professional brand. This is the standard that professional holiday rental agencies achieve — and it is accessible to individual hosts at minimal cost.
A .co.uk domain costs around £5 to £10 per year. A .com domain is £10 to £15 per year. Mailgun email sending via LetPilot is included in your LetPilot subscription. The total cost is minimal compared to the professional impression it creates and the deliverability improvement it provides on every single booking you handle.
