Case Study: Hotel Email Send Time Optimization as a Revenue Lever

Overview

This case study focuses on hotel email send time optimization, using guest behavior and performance data to determine when email timing influences engagement and booking outcomes. HMA Intelligent Marketing partnered with a luxury California resort to understand whether email send timing influenced engagement and revenue performance. Creative, offers, and segmentation were already actively optimized. Send timing, however, followed generalized industry guidance rather than guest behavior specific to the property.

HMA analyzed more than 1.6 million email sends across the resort’s full email program to determine how timing aligned with guest intent and where performance could improve without increasing send volume.

Scope of Analysis

The analysis covered campaigns sent between Q4 2024 and Q4 2025 across the resort’s primary email programs:

• Leisure and limited-time offers driving room revenue and direct bookings

• Food and beverage and spa campaigns focused on on-property spend

• Newsletters and brand nurture content

• On-the-books extensions, early arrival messaging, and booking recovery emails

In total, the dataset included more than 1.68 million sends and over 333,000 opens.

Analytical Approach

The goal was to isolate timing as a performance variable. To do this, HMA:

• Calculated weighted open rate by day and campaign type using total opens divided by total sends

• Calculated weighted click-to-open rate using total clicks divided by total opens

• Segmented results by campaign category and guest intent

• Removed outliers to avoid skew from single high-performing sends

• Benchmarked results against travel and hospitality email performance standards

This method surfaced repeatable timing patterns tied to guest behavior rather than one-off campaign success.

Hotel Email Send Time Optimization Across Campaign Types

Leisure and Limited-Time Offers

Midweek timing consistently outperformed other days for stay-focused campaigns. Wednesday produced the highest weighted open rate at 22.83% and the strongest click-to-open rate at 16.75%. Tuesday followed closely. Thursday underperformed across both metrics.

The data showed guests were more receptive to booking-related messages midweek, when planning behavior peaked.

Food and Beverage and Local Campaigns

Food and beverage and spa campaigns followed a shorter decision window. Tuesday generated the highest open rates. Wednesday delivered the strongest post-open engagement, with click-to-open rates exceeding 12%. Highly targeted segments regularly achieved open rates above 30%.

These campaigns benefited from timing aligned to near-term intent rather than long-range planning.

Newsletters and Brand Content

Newsletters performed best on Sundays. Open rates reached 20.26%, with click-to-open rates at 6.31%. Engagement patterns reflected browsing behavior rather than purchase intent, reinforcing the role of newsletters as brand touchpoints rather than conversion drivers.

On-the-Books and Triggered Programs

Triggered programs performed best when tied directly to guest behavior instead of fixed weekdays. Stay extension emails averaged 35.8% opens. Booking recovery emails achieved 37.8% opens, 5% clicks, and an 8.1% conversion rate.

Timing reinforced intent rather than competing with it.

Strategic Outcome

HMA translated these insights into a send timing framework now used to guide the resort’s email calendar. Timing is aligned to campaign purpose and guest behavior, improving engagement without increasing send frequency or altering promotional cadence.

Business Impact

By shifting from generalized benchmarks to a behavior-driven timing strategy, the resort improved engagement across all campaign categories and met or exceeded hospitality benchmarks, particularly for click-to-open performance.

Conclusion

This case study demonstrates how aligning email send timing with guest intent improves performance when supported by clean guest data and disciplined analysis. While the results reflect a single luxury resort, the framework is designed to scale across hotel brands, independent properties, and management groups.

For hotels evaluating email marketing performance, booking recovery, or CRM optimization, send timing remains a practical lever with measurable revenue impact when grounded in guest behavior rather than assumptions.

Explore Send Time Optimization for Your Property

Every hotel’s guest behavior is different. The timing patterns uncovered in this case study reflect one property’s data, but the analytical framework is designed to surface timing opportunities specific to your guests, your campaigns, and your booking windows.

HMA applies the same send time optimization approach across hotel email marketing programs, automated journeys, and booking recovery lifecycles to identify when guests are most likely to engage and convert, without increasing send volume or list fatigue.

If you want to understand how send timing is performing within your own email ecosystem, HMA can analyze your data and build a property-specific timing framework tied to guest intent and revenue outcomes.
