Every guest who books through Booking.com goes into Booking.com’s database. Not yours.
When that guest is ready to travel again, Booking.com sends them a promotional email, shows them your property alongside five competitors, and charges you 20% commission when they click through and rebook. You paid to acquire them the first time. You pay again the second time. You pay every time, forever.
Your email list is the only place where that cycle stops. A guest in your Mailchimp audience is a guest you can reach for free, forever, with no intermediary taking a cut.
This guide covers what hotel email marketing actually does for independent properties, how to capture the OTA guests who are already slipping through your hands, and the math on what a well-managed email list is worth compared to what you’re currently paying Booking.com.
Why Your Email List Is Worth More Than Any OTA Listing
Here’s the repeat guest math that most hotel owners have never actually seen.
Returning guests are far more likely to rebook than first-time guests, and they tend to spend more per stay.
When a repeat guest books through Booking.com, you pay 20% commission. Again. As if they were a stranger you’d never met. The OTA doesn’t care that they stayed with you last June. They charge the same rate on every single transaction.
When a repeat guest books through your direct booking engine after receiving your email, you pay $0 in commission. That’s the entire difference.
Run the numbers for a 20-room boutique hotel. Say you capture 40 guests per month to your email list (a 30% capture rate from 130 monthly guests). After one year, that’s roughly 480 people. In year two, if 10% of your list books a return stay each month, that’s 48 potential rebookings per month. At a 20% conversion rate: roughly 10 direct bookings per month from email alone.
10 bookings x $175 ADR x 20% commission avoided = $350/month in commission recovered. Annual: $4,200/year that previously went to Booking.com.
And that number grows every month you add new guests to the list.

The Campaign Types That Actually Drive Hotel Bookings
Most hotel owners think “email marketing” means sending a monthly newsletter. It’s broader than that, and the campaigns that drive real revenue are almost entirely automated.
Welcome Email (Sent Immediately After Booking)
The moment a guest completes a reservation, a welcome email goes out automatically. Confirmation details, what to expect at check-in, and a first opportunity to upsell: room upgrade, early check-in, F&B package, a spa credit.
Transactional emails like booking confirmations have some of the highest open rates of any email type. Your guests are reading this email. Make it do more than confirm a booking number.
Pre-Arrival Email (7–10 Days Before Check-In)
This is the most underused campaign in hotel email marketing, and one of the most effective. Pre-arrival emails tend to earn higher click-through rates than most promotional campaigns you’ll ever send.
A good pre-arrival email covers: local recommendations, parking details, any property notes, and a time-sensitive upsell offer. “Add breakfast for two at $29/person, available until 48 hours before arrival.” Guests are in planning mode. They’re receptive.
This email also does something else: it starts building a direct relationship before the guest even arrives. They’re not just a Booking.com reservation number. They’re a guest who’s heard from you personally.
Post-Stay Email (3–5 Days After Checkout)
Three objectives: thank them, ask for a review, and give them a reason to rebook direct.
“Thank you for staying with us. If you have a moment, we’d love a Google review. It means everything to a small property. And when you’re ready to come back, book direct at our website for 10% off your next stay.”
That final line is the pivot from OTA guest to direct guest. One sentence. Automated. Sent to every checkout, every time.
Seasonal and Promotional Campaigns
Beyond the automated sequences, send 1-4 promotional emails per month. Upcoming holidays, local events, limited-availability packages, last-minute room offers. These campaigns keep your property visible between stays and drive incremental bookings from people who weren’t actively planning a trip.
Segment by past behavior: guests who stayed for a weekend vs. business travelers vs. couples have different offers that resonate. Pairing email with hotel social media keeps your brand visible to past guests across every channel between stays.
The OTA Guest Problem (And How to Solve It)
Here’s the question most hotel owners have but rarely ask out loud: Booking.com gives me a proxy email address for my guests. How do I get their real email?
You can’t get it from the booking record. But you can capture it before and after the stay through channels you control.
Five tactics that work for independent hotels:
-
Pre-arrival form. Send a pre-arrival form 7-10 days before check-in: dietary preferences, parking needs, any special requests. Ask for a direct email at the top: “We’ll use this to send your pre-arrival details.” Guests who fill it out give you a real address.
-
Check-in capture. Train front desk staff to ask: “May we add you to our guest newsletter? We send exclusive direct booking rates to our list.” Simple script, consistent execution, no pressure.
-
Wi-Fi registration. Require an email address for property Wi-Fi access. Keep the form minimal and the value clear: “Stay connected. Sign up for our guest Wi-Fi.”
-
Post-stay reply prompt. The Booking.com proxy address still receives email. Reply to it with: “Thank you for your stay. For your next visit, we’d love to offer you a direct booking rate. Add your email here to receive exclusive guest offers.” Some guests respond. Enough to matter.
-
Direct booking incentive on checkout. Leave a card in the room or include it with the bill: “Book direct next time and save 10%. Visit [yourhotel.com] or scan this QR code to sign up for our guest list.”
Using two or three of these tactics, you can steadily capture a meaningful share of all guests, including OTA arrivals.
What Hotel Email Marketing Costs vs. What It Returns
Email is one of the highest-returning marketing channels available to a hotel, and few other channels come close.
On the tool side, Mailchimp runs roughly $30-75/month, depending on list size.
Setting Up Hotel Email Marketing on Mailchimp
Mailchimp is the right starting point for most independent hotels. It’s well-documented, integrates with most booking systems and property management software, and the pricing scales with your list size rather than requiring a large upfront commitment.
The setup involves four steps:
1. Create your audience and import existing contacts. If you have any past guest emails from direct bookings, invoices, or check-in records, start there. Even a list of 50 past guests is a foundation.
2. Build three automated sequences before anything else. Welcome email (triggered by booking), pre-arrival email (triggered 7-10 days before arrival date), post-stay email (triggered 3-5 days after checkout). These three automations generate revenue passively once configured.
3. Segment from day one. Tag guests by source (direct vs. OTA), stay type (leisure vs. business), and visit frequency (first-time vs. repeat). These segments let you send relevant offers instead of generic blasts.
4. Schedule one monthly promotional campaign. Keeps the list warm, keeps your property front of mind, and gives former guests a reason to rebook before they have an active travel need.

The List OTAs Can’t Touch
Booking.com can change their algorithm. Expedia can increase commissions. OTA rankings can shift overnight and there’s nothing you can do about it.
Your email list is yours. It doesn’t belong to a platform. It doesn’t charge you per use. It doesn’t de-list you. It grows in value every month you add guests to it and every time you send a campaign that brings someone back.
A properly built hotel email marketing program is one of the few things in hospitality marketing that compounds over time instead of resetting every year. Your Google Ads spend resets to zero if you stop paying. Your social media following is rented from a platform. Your email list is owned infrastructure.
We’ve launched 50+ hospitality websites as part of Designodin’s track record of 200+ projects since 2016.
