WhatsApp for boutique hotels on SiteMinder: what we learned from 62 templates

The Hotelminder advisory team spent two months writing WhatsApp threads for four boutique properties in Barcelona and Berlin. Sixty-two templates emerged. Nine we later deleted.

Editorial cover

The GuestJoy Concierge Expander that Hotelminder ships on the shortlist carries 62 message templates. That number is not a design choice — it is the residue of a two-month writing exercise the advisory team ran at four boutique properties in Barcelona and Berlin last spring. We wrote 71 templates, tested them in live pre-arrival threads for eight weeks, and deleted the nine that did not survive contact with real guests. These are the notes from that exercise.

The pre-arrival phase is where warmth is earned

Fourteen of the surviving templates cover the 72 hours before check-in. This is the phase most enterprise messaging tools flatten with generic "Dear guest" phrasing. Boutique properties earn or lose the guest's expectation in this window. Our best-performing template — a soft ask about arrival time, phrased as "so we can have a coffee ready if you want one" — landed a 78% reply rate across 340 threads. The generic version we tested first ("Please confirm your arrival time") landed 31%.

The phrasing detail that mattered: mention a specific small courtesy the property will do based on the reply. Not a promise the property cannot always keep — the coffee is easy — but a specific one. Guests reply to specific.

The nine we deleted

Two were upsell templates disguised as concierge messages. Guests read through them instantly, replied in a way that felt cold, and the entire thread went downhill. We do not send upsell messages on WhatsApp anymore — that channel is for concierge, upsell goes on email or the direct-booking widget where the phrasing is more honestly transactional.

Three were overly formal (the words "we would like to inform you" appeared in all three). Boutique guests treat those as spam even from a boutique property. Deleted.

Two were culturally miscalibrated — one asked a German guest about their "dietary restrictions" with an American phrasing that read as clinical; one asked a Spanish guest about pet fees in a tone that assumed the fees were negotiable when they were not. Rewrote both, deleted the originals.

The last two were duplicates of email templates. We had lifted them from the property's existing email flow assuming they would transfer. They did not. WhatsApp phrasing is shorter, warmer, and often more casual than email phrasing from the same property. We had to write the WhatsApp version from scratch.

The day-before-departure practical note

Nine templates cover the day before check-out. This is a category we did not initially plan to write templates for — we assumed the pre-arrival and in-stay phases were where the value lived. We were wrong. Guests at boutique properties consistently found the day-before note — breakfast timing, taxi window, luggage storage, weather for departure day — the most memorable message from their stay. Reply rate 42%, but reply sentiment (measured qualitatively by the advisor reading them) was warmer than any other template category.

Languages that matter

All 62 templates ship in English, French, Spanish, Italian, German and Dutch. Portuguese and Catalan are on the roadmap for later this year — enough boutique properties in Lisbon and Barcelona have asked for them. Translation is not machine translation; every language variant was drafted by a native speaker on the advisory team or a contracted editor, then reviewed by the property's concierge team before it went live.

Editorial note. Signed by Sofía Roig, Hotelminder advisory, Barcelona. The four properties were 26-, 34-, 41- and 52-room boutique hotels. Each property retains ownership of any custom template phrases their concierge team wrote — the Expander template library is a starting point, not a lock-in.

What we would tell a general manager on day one

Spend ninety minutes with your head concierge on the template library before you switch the Expander live. Delete the templates that do not fit your voice; adjust the ones that almost fit; leave the rest. Do not treat the library as a fixed asset. The templates are a floor, not a ceiling. If your property's voice is distinctly its own — and boutique hotels' voices should be — the templates will drift away from the defaults within a month. That drift is the point.
