Choosing between Hapi Guest by Hapi and Digital Marketing (rezStream) hinges on what your hotel prioritizes—system integration or guest engagement through email marketing. Both aim to enhance your property’s performance but approach this from different angles: Hapi centralizes guest data and simplifies complex integrations, while rezStream focuses on building relationships through targeted email campaigns. Your decision should align with your hotel’s core needs—are you looking for a unified tech backbone or a direct line to your guests?
Hapi’s strength is in connecting your disparate systems into a single profile, reducing costs and streamlining operations. rezStream, on the other hand, excels at nurturing guest loyalty through sophisticated email marketing and content strategies. Do you need a robust platform for tech infrastructure, or is improving direct guest communication your main focus?
Hapi Guest and rezStream serve fundamentally different purposes, which influences their suitability for your hotel. Hapi is best suited if your team struggles with integrating multiple property management and operational systems, especially if you operate a branded or independent hotel with complex tech stacks. It consolidates data from PMS, CRM, POS, and other systems, making guest insights more accessible and actionable.
rezStream excels if your hotel heavily relies on direct marketing and email campaigns to drive occupancy and guest loyalty. Its tools are tailored to craft engaging email content, segment audiences, and automate campaigns, which can significantly impact your revenue.
However, rezStream’s review base is limited, with no recent feedback, meaning its performance and support might be less predictable. Conversely, Hapi’s recent reviews are overwhelmingly positive, with high ratings across support, ease of use, and value. Are you looking to unify your systems or to deepen your guest relationships?
If your hotel needs a reliable, extensive integration platform to connect your PMS, CRM, POS, and other operational systems, go with Hapi. Its 66 verified partners and extensive feature set—like guest profiles, data warehouses, segmentation, and automation—make it ideal for hotels seeking operational efficiency and data control.
If your primary goal is to boost engagement and revenue through personalized email marketing campaigns, rezStream is the superior choice. Its focus on email marketing, with a dedicated team and content strategy, has helped clients increase occupancy from 55% to 85%, according to reviews. For hotels that prioritize direct communication and guest loyalty, rezStream offers specialized tools.
In summary, choose Hapi if system integration and data management are your pain points. Opt for rezStream if your main objective is to enhance guest relationships and increase revenue through targeted email campaigns.
Hapi receives a high ease-of-use rating of 4.64/5, supported by onboarding reviews that praise its quick deployment and knowledgeable support team. Its interface is designed for technical teams comfortable with complex integrations, and many users note that its setup is straightforward given the scope of its integrations.
rezStream is rated even slightly higher at 4.8/5, with user reviews emphasizing its intuitive platform and dedicated support. Users highlight how simple it is to craft campaigns, segment audiences, and manage marketing efforts, with a seamless onboarding process.

Hapi offers a rich feature set, including 30 unique functionalities like data migration, guest profiles, automation, segmentation, GDPR/CCPA compliance, and an open API for custom integrations. These features allow hotels to create a centralized, flexible platform for managing guest data and operations.
rezStream, despite offering no additional features beyond email marketing, provides critical tools tailored specifically for guest engagement.

Edge: rezStream.
Hapi boasts 66 verified partners, including major PMS, CRM, and POS systems, making it a highly adaptable middleware solution. Its extensive integrations—covering systems like 4SUITES, Juyo Analytics, WebRezPro, and HotelIQ—enable comprehensive data management across your property.
rezStream has only 6 verified partners, mainly focused on reservations, booking, and loyalty systems like Cloudbeds and Stash Rewards. Its integrations are limited but sufficient if your hotel’s primary focus is on email marketing rather than operational system connectivity.
Edge: Hapi.
Hapi’s recent reviews are overwhelmingly positive, with an overall rating of 4.8/5 and a NPS score of 9.58/10. Hoteliers in diverse segments, especially branded and independent hotels, rate it highly for its ease of use, support, and value.
rezStream’s limited review data makes it difficult to gauge current satisfaction. The available feedback is positive, emphasizing its role in revenue growth, but the absence of recent reviews indicates less current user insight.
Edge: Hapi.
Hapi charges a flat monthly fee of $1,400, with no implementation or trial fees, making it straightforward for hotels to budget. Pricing includes comprehensive data integration and management features.
rezStream’s pricing is not publicly listed, which suggests it may vary based on the scope of services and integrations. Most hotels pay a monthly fee for their email marketing and related services, but specific costs are determined through direct consultation.

Not ideal if:
Hapi Guest and rezStream cater to different hotel needs. Hapi is a robust, comprehensive system designed to unify operational data, improve efficiency, and enable sophisticated segmentation. rezStream specializes in nurturing guest relationships through compelling email marketing and content strategies.
Choose Hapi if your hotel’s challenge is system complexity and data silos. Its extensive integrations and features suit larger, more complex properties seeking operational harmony.
Opt for rezStream if your focus is on direct marketing and guest loyalty. Its dedicated email tools and strategic support help smaller to mid-sized hotels increase revenue through targeted communication.
In conclusion, the right choice depends on your hotel’s core priorities: infrastructure and data management or guest engagement and marketing. Both products are valuable, but Hapi’s larger review base and recent positive feedback make it the more reliable, proven option right now.
