Guests who booked through Booking.com the first time can book direct the next time. This is how to use email to own that relationship before the OTA does.
When a guest books through Booking.com, Booking.com owns the relationship. When they check in and give you their email, you do.
The OTA brings the guest the first time. Your job is to bring them back directly. Every OTA guest who re-books through your own channel is a guest you paid commission on once and will never have to again.
Email is the most cost-effective way to make that happen. It fits inside a broader hotel direct sales strategy as the follow-up layer, once your on-site conversion is working. No commission, no ad spend, no algorithm between you and the guest.
Building the list: the only rule that matters
You cannot email guests you do not have addresses for. The address collection moment is at check-in or in the pre-arrival email. Make it routine. "May we add you to our guest mailing list for exclusive direct offers?" is a simple ask that most guests accept.
For new enquiries and bookings that come through your own website, capture the email as part of the booking flow. These guests are already your direct audience.
Do not buy email lists. Do not scrape. Your hotel email list should only contain people who have stayed with you or actively opted in through your website.
The 3 emails every hotel needs
The post-stay follow-up (send 3 to 5 days after checkout). Thank the guest. Ask for a review. Include a note that they can book direct next time for a specific benefit. Short. Friendly. No hard sell.
The re-engagement email (send 60 to 90 days after checkout). This is where the direct booking offer lives. "You stayed with us in October. We would love to have you back. Book direct for your next visit and we will include breakfast." Reference the previous stay. Make the offer specific. Include a direct link to your booking engine.
The seasonal offer (2 to 4 times per year). Tied to your highest demand periods or your lowest occupancy windows. "We have a few rooms available for the long weekend in May. Book direct before Thursday for early check-in." Creates urgency without discounting your standard rate.
What makes hotel emails work
Personalization by stay type. A couple who stayed for a weekend anniversary trip and a business traveler who visited for a conference are different people with different reasons to return. If your PMS or booking system records stay purpose, segment your list and vary the offer accordingly.
Subject lines that do not sound like marketing. "Your next stay" outperforms "Exclusive offer inside." "We saved you a room" outperforms "Book now and save 10%." Write subject lines the way you would if you were emailing a guest you know.
One CTA per email. Every hotel email should have one thing it wants the guest to do. Click through to the booking engine. Not three options, not a link to your Instagram, not a newsletter signup. One action.
GDPR and consent
In the EEA, you need a legal basis to send marketing emails. The most practical basis for hotels is opt-in consent collected at check-in or booking. Keep a record of when and how each subscriber consented. Include an unsubscribe link in every email.
Transactional emails (booking confirmation, check-in instructions) do not require marketing consent. Stay emails require it.
Connecting email to your direct booking offer
The email drives the click. The hotel website closes the booking. Tracking your hotel website conversion rate before and after launching an email campaign shows you exactly how much of the lift comes from each channel. If the guest clicks through from your email and lands on a homepage with no direct booking offer visible, a significant percentage will go back to Booking.com to complete the reservation.
The email and the on-site offer need to work together. Read how to build a hotel direct booking offer that actually converts so the landing experience matches the email promise. The email says "book direct for free breakfast." The website shows the same offer in a widget when the guest lands. The booking engine references the offer. Consistent message from email to booking confirmation.
