Choosing between Hapi Guest by Hapi and Mail Relay by Inxmail hinges on your hotel’s core needs—whether you prioritize a unified CRM and integration platform or advanced email marketing capabilities. Hapi Guest addresses the challenge of connecting disparate hotel systems, creating a complete guest picture that enhances personalization. Mail Relay focuses solely on streamlining large-scale email campaigns, vital for boosting engagement but lacking broader CRM functionalities. Both solve communication issues but cater to different operational priorities.
If your team is looking for a robust, all-in-one hospitality CRM that simplifies integrations and enriches guest data, Hapi Guest is the clear choice. Conversely, if your hotel’s primary goal is to optimize email outreach and automate campaign management, Mail Relay might suit your needs better. But which one provides the most value and reliability for your specific hotel operation?
Hapi Guest’s 60 reviews and high recent review activity overwhelmingly favor it as the more proven and trusted solution. It boasts an impressive 4.8/5 overall rating, a 4.83/5 customer support score, and a 9.58/5 NPS, reflecting deep user satisfaction. In contrast, Mail Relay has no recent reviews or ratings, indicating limited market presence and uncertain ongoing support.
For hoteliers seeking a comprehensive CRM and integration platform with proven performance, Hapi Guest’s extensive review base and high satisfaction scores make it the recommended choice. Mail Relay’s strengths are in email marketing, but without recent reviews or verified customer feedback, confidence in its long-term value is limited.
Hapi Guest and Mail Relay are designed to improve communication and guest management but target different hotel needs. Hapi Guest excels at integrating multiple operational systems, creating a unified guest profile, and supporting targeted marketing efforts. It simplifies complex data flows across PMS, CRM, POS, and other hotel systems, enabling personalized guest interactions.
Mail Relay, however, is specialized in email marketing—sending bulk campaigns, automating responses, and analyzing engagement metrics—without deep system integration features. While Mail Relay can boost outreach, it lacks the broad operational focus that Hapi provides.
The core divergence lies in scope: Hapi is a CRM platform that manages guest data and operational connectivity, while Mail Relay is solely an email marketing tool. Are you aiming to improve overall guest engagement through system integration, or just enhance your email campaigns? This fundamental difference guides the choice.
If your hotel needs a centralized platform to consolidate guest data from multiple sources, automate personalized campaigns, and view guest interactions in one place, Hapi Guest is the superior choice. It’s especially suited for hotels in need of a complete CRM solution that can connect with existing property management, POS, and other operational systems.
If your team’s focus is on executing large-volume email campaigns, improving outreach efficiency, and tracking engagement metrics, then Mail Relay offers specialized features. However, with no recent reviews or verified customer feedback, its reliability and ongoing support remain uncertain.
For hotels with a broader operational challenge—unifying guest data, automating marketing, and improving guest experiences—Hapi is the recommended path. For those purely seeking email outreach, Mail Relay can be considered, but only if confidence in its current market standing is established.
Hapi Guest scores a 4.64/5 for ease of use, with users praising its intuitive interface and straightforward onboarding process. Reviewers highlight that “deployment is quick,” and “support is responsive,” making staff adoption generally smooth. Its well-designed dashboards and automation tools reduce the learning curve, helping your team start realizing benefits swiftly.
Mail Relay, with no recent reviews or detailed user feedback, offers an unclear picture of usability. Given the absence of recent data, we cannot confidently assess its interface or onboarding experience.
Edge: Hapi Guest.
Hapi Guest offers a suite of 30 exclusive features, including data migration, guest profiles, segmentation, A/B testing, email templates, transactional templates, GDPR and CCPA compliance, and a centralized data warehouse. These capabilities enable deep personalization, sophisticated automation, and comprehensive guest management.
Mail Relay lacks publicly available feature details or comparable functionalities, suggesting it is primarily a campaign management tool without extensive integration or personalization features. Its primary strength appears to be in bulk email sending and basic analytics.
Edge: Hapi Guest.
Hapi’s support score of 4.83/5 is backed by 60 recent reviews, with customers describing the team as “knowledgeable,” “responsive,” and “a true partner.” Many users report that support during onboarding and ongoing troubleshooting exceeds expectations, making the implementation process less stressful.
Inxmail, which owns Mail Relay, has no recent verified reviews or detailed support ratings. Without current user feedback, it’s impossible to judge the quality or responsiveness of their support team.
Edge: Hapi Guest.
Hapi Guest integrates with 66 verified partners, including major hotel software like Suites, Juyo Analytics, Uniguest, WebRezPro, and Event Temple. This extensive network ensures your hotel can connect virtually all operational systems, from PMS to point-of-sale platforms.
Mail Relay offers no publicly listed integrations or verified partner connections, limiting its ability to synchronize with your existing hotel systems. Without integration support, it may require manual data handling or custom development.
Edge: Hapi Guest.
Hapi Guest enjoys a 4.8/5 overall rating with 60 reviews, most in the last six months. Hotels of all sizes, from independents to large brands, rate it highly for ease of use, support, and overall value. Its recent reviews suggest ongoing user satisfaction.
Mail Relay has no recent reviews or ratings, making it impossible to determine how hotels perceive its performance or support quality presently.
Edge: Hapi Guest.
Hapi Guest costs $1,400 per month with no mention of implementation or ongoing charges. It offers a straightforward subscription model without freemium options or per-room fees.
Mail Relay’s pricing details are not publicly available, and no trial options are listed. This lack of transparency makes it difficult to compare value or determine if it fits your budget.
Not ideal if you prefer a simple email marketing tool without broader operational needs. Smaller hotels with minimal system complexity might find it more than they require.
Not ideal if your hotel requires deep integration across multiple operational systems or a comprehensive guest CRM platform. Hotels seeking to unify guest data and automate personalized interactions should look elsewhere.
Hapi Guest and Mail Relay serve different core hotel needs. Hapi Guest is a full-fledged CRM and integration platform that consolidates guest information, automates personalized marketing, and connects with numerous hotel systems. Mail Relay is a dedicated email marketing tool optimized for bulk outreach and engagement tracking but lacks system integration capabilities.
Choose Hapi Guest if your hotel aims to unify guest data, streamline operations, and deliver tailored experiences. It’s ideal for properties seeking a scalable, reliable platform with proven reviews, high satisfaction, and extensive integrations.
Opt for Mail Relay only if your primary goal is high-volume email campaigns without the need for operational or guest data integration. Its utility is limited for hotels looking to develop a holistic marketing and guest management strategy. However, due to the lack of recent reviews and verified customer feedback, confidence in Mail Relay’s current support and feature set is questionable.

How customer-centric is this organization?

| Reach, Staying Power & Resources |
|
How extensive is this company's reach and resourcing?
