# HolidayHero vs SendSquared

> SendSquared is a US hospitality CRM and marketing platform, strong on guest data, direct-booking campaigns and an enterprise voice stack with AI phone agents.
HolidayHero runs the whole stay instead: the guest app, arrival, upsells and operations between the booking and the review, on any PMS, with published pricing and EU data residency.

## Detail

SendSquared is a hospitality CRM and marketing platform, built to unify guest data across a portfolio and turn it into direct bookings through email, SMS, postcards and a call centre with AI voice agents. HolidayHero runs the whole stay. It covers the guest app, arrival, messaging, upsells, suppliers and operations that sit between the booking and the review, for hotels, groups, parks, hostels, aparthotels and rentals alike, beside whatever PMS you already use.

If you are weighing SendSquared against HolidayHero, you are choosing between a CRM that markets to guests and a platform that runs their stay. Here is the honest version.

### Credit where it's due

SendSquared is a serious piece of software in its lane. Its AI Voice agents resolve a large share of inbound calls autonomously, and behind them sits a full enterprise phone system with queues, IVR, recording and PMS data on screen when the phone rings. The guest data side is real too: a customer data platform with lifetime-value modelling, dynamic segments off live PMS data, revenue attribution back to campaigns, plus channels most guest-experience tools never touch, like physical postcards, a WiFi captive portal and owner acquisition. If your bottleneck is inbound call volume and direct-booking marketing, that is a credible stack.

### Why HolidayHero

The difference is scope. SendSquared is built to reach guests: email, SMS, WhatsApp, Airbnb, phone, postcards. HolidayHero is built to run what happens once they arrive, and it is built for every kind of operator, not just rental portfolios. Hotels, hotel groups, holiday parks, hostels, aparthotels and rentals all fit, on hotel PMSs like Mews, Clock PMS and RoomRaccoon as readily as rental ones. SendSquared is explicit that it is aimed at companies running 50 to 5,000+ units. If you are a 30-room boutique, or you want the stay itself managed rather than the mailing list, that focus is a ceiling.

The guest-facing layer runs deeper. HolidayHero's guest app carries your branding on your own domain, adapts stage by stage as the reservation progresses, and lets you create, sort and hide your own sections. Guests and operators build a shared in-app itinerary, guidebooks and amenities sit alongside local events pushed straight into the app, and everything auto-translates into the guest's language. SendSquared's guest surface is a browser guidebook: well built, branded, with conditional blocks and an itinerary planner, but no documented multi-language support, no local events calendar, and no documented own-domain option.

Arrival is where the gap is widest. HolidayHero handles online check-in with configurable fields, ID and passport capture with document types that adapt to the listing's country, guest registration filed automatically with the Spanish authorities through SES.Hospedajes (Italy and Dubai in progress), and a full smart-home layer: not just locks like Goki and Bold, but lighting, plugs with energy monitoring, thermostats and sensors, gated by reservation stage. SendSquared collects ID documents through the guidebook and logs the terms acceptance, which is genuinely useful, but its own pages document no authority filing and no lock or device integration at all.

Revenue works differently. HolidayHero sells upsells and local experiences from a real in-app catalogue with VAT by country, availability and images, routes guest inquiries directly to the supplier who fulfils them through a supplier portal with no front desk relaying in the middle, splits the commission automatically, and posts charges to the folio through supported PMSs. SendSquared's own pages describe pre-arrival upsell messaging, early check-in, add-ons and upgrades, but no in-app catalogue, no bookable experiences and no folio posting.

Then there is how you buy it, and where your data lives. HolidayHero publishes per-unit pricing from €6.50 per unit per month, you can start on a trial yourself, and onboarding is a one-time fee of €100 to €250. SendSquared is custom-quoted by unit or key, offers no free trial, and puts full implementation at six to eight weeks. On data, HolidayHero is EU-native with GDPR compliance and EU data residency. SendSquared's privacy policy is direct about the alternative: the company is based in the United States, and information from outside the US is transferred to, stored in and processed in the US under Standard Contractual Clauses. For a European operator that is a procurement conversation before it is a product one.

Finally, HolidayHero gives you two ways to build on it: a Headless Guest App, so the guest experience runs inside your own app or site with HolidayHero as the engine, and an integration API for system-to-system work such as wiring in your own message channels. SendSquared publishes webhooks, an MCP server and a CLI, but no public API reference.

### Capability by capability

Give SendSquared its due: on the messaging core the two are close. A unified inbox, WhatsApp, an AI agent answering guests autonomously, rule-gated scheduled messaging, event-driven automations, surveys and review routing, multi-property and multi-brand management are all strong on both sides, and SendSquared's voice channel goes somewhere HolidayHero does not publish at all. Where HolidayHero pulls ahead is everything wrapped around that core: online check-in, authority registration, smart-home access, custom domains, stage-based guest-app sections, auto-translation, local events, an upsell and experiences catalogue, folio posting, direct-to-supplier inquiries with automatic commission splits, a composite 0 to 100 guest engagement score, the headless guest app, the integration API, published self-serve pricing and EU data residency.

### Which fits you

If you run a large US rental portfolio and your problem is inbound calls and direct-booking marketing, SendSquared is a fine pick and genuinely good at it. If you run hotels, parks, hostels, aparthotels or a mixed portfolio, if you operate in Europe, or if you want the stay itself run end to end (arrival, guest app, suppliers, upsells and operations) on pricing you can read today, HolidayHero is the platform built for it.
