WhatsApp with chatlyn Spa Resort Geinberg, WhatsApp campaigns vs typical email
The booking confirmation opens the conversation
Your PMS tells chatlyn when a guest books, arrives and leaves. chatlyn sends the right WhatsApp at each moment, in the guest’s language, with their name, dates and room already filled in.
Five moments cover the stay: booking, arrival, check-in, check-out and after the stay. A cancellation stops the remaining messages for that booking.
Offers for the right guests, not the whole list
Every guest record holds the stay from your PMS and every conversation. Build a segment in a few clicks and it keeps itself current: arriving this week, in-house tonight, birthdays, your loyalty tiers.
Send one approved template to the whole segment with Send WhatsApp. Guests who opted in get an offer that fits them, which is what keeps open rates high and your number in good standing.
One scan, a whole concierge
A QR code on the room card or at the pool opens WhatsApp with your concierge menu. Guests tap through spa times, dinner or excursions, and your team only confirms.
Menus use photos, buttons and lists of up to ten options. No app to download, and you see how far guests get, step by step, and which links they open.
The AI and your team, on one WhatsApp number
The WhatsApp Business app was never built for a team. On chatlyn everyone works the same number from the browser or the mobile app, with conversations assigned to the right person and notes for the next shift.
The AI answers first whenever you want it to, from your own knowledge, and hands over when a person is needed. Two-way translation lets your team read in their language and reply in the guest’s.
WhatsApp that keeps your number in good standing
chatlyn connects your hotel to the WhatsApp Business API through 360dialog, a Meta-approved provider, so you never work in a second tool.
Meta decides what reaches a guest: template categories, the 24-hour window, daily limits and quality ratings. chatlyn checks every template before it goes to Meta, shows the window on every conversation and reads your quality rating live, with every failed send explained.
Official WhatsApp, GDPR compliant
chatlyn is a Meta Business Partner and runs on the official WhatsApp Business API, not the consumer app and not grey-market tools. Your guests’ data stays protected under European rules.
- Official Business API Connected through 360dialog, a Meta-approved provider, with Meta’s business verification.
- Hosted in Frankfurt The chatlyn platform runs in the EU, GDPR compliant, with a data processing agreement under Art. 28.
- Encrypted and masked Data is encrypted at rest with AES-256, and personal data is masked before any AI sees it.
- Opt-in only Offers go only to guests who agreed to hear from you, which also keeps your number in good standing.
30 butlers, one WhatsApp number
Every suite at The St. Regis Le Morne comes with a butler, and guests wanted to reach theirs on WhatsApp. With chatlyn the whole butler team works one number: a QR code in the suite opens the chat, the conversation goes to the right butler, and every reply after the welcome is written by a person.
“This is the first hotel where we genuinely used the WhatsApp service every day, because every small idea or request was handled instantly and with care.” Guest review, TrustpilotRead the St. Regis story
Upsells happen in conversations, not newsletters
A newsletter is a message nobody is expected to answer. On WhatsApp the guest replies, asks about the spa or a table for tonight, gets an answer on the spot and books. See what those conversations are worth across your hotels.
€162 per room, across 120 rooms
WhatsApp conversation95% open it. Guests reply, ask and book. An estimate, not a promise. It assumes 2.5-night stays and that 5% of guests who read an offer book it, which is the conservative case: on WhatsApp they can also ask first. Open rates come from Spa Resort Geinberg, a chatlyn customer: 95% on WhatsApp against about 20% for email.

Questions about WhatsApp for hotels.
It means using WhatsApp as a guest channel: booking confirmations, pre-arrival information, offers and in-stay requests on the app guests already use, answered by your team and the AI. With chatlyn it runs on the WhatsApp Business API, connected to your PMS so each message fits the guest’s stay.
Yes, and chatlyn sets it up with you. chatlyn connects through 360dialog, a Meta-approved provider, so you never work in a second tool. You need a Meta business portfolio, your business details for Meta’s verification and a phone number for the property.
Yes, once it is removed from the WhatsApp app. After connecting, the number runs only through chatlyn: your whole team uses it there, in the browser or the mobile app, and it no longer works in the WhatsApp app itself.
Meta charges for WhatsApp messages by message type and the guest’s country. We pass Meta’s cost through, with our service charge, on your monthly chatlyn invoice, and we show you the current rates in the call.
After a guest writes to you, you can reply freely for 24 hours. Outside that window a conversation can only start with a template Meta has approved. chatlyn shows the window on every conversation and offers your templates when it closes, and a guest reply opens it again.
Yes, to guests who agreed to hear from you, with a Marketing template. Meta limits how many marketing messages each person receives per day across all businesses, so we recommend about one offer per guest every one to two weeks, sent to a segment rather than the whole list.
Meta rates the quality of every business number, and guests reporting messages as spam lowers it. What keeps a number in good standing is what chatlyn is built around: guests who opted in, offers sent to segments, marketing kept out of booking messages and the quality rating in view. We set this up with you during onboarding.
chatlyn connects to PMS systems including Oracle OPERA Cloud, Mews, Apaleo, Protel, Guestline and Clock. Booking data flows one way, from your PMS into chatlyn, so nothing in your PMS is changed. Tell us your PMS in the call and we will show you how the connection works for it.
Yes. The AI answers from your hotel’s own knowledge, in the guest’s language, and hands over to your team whenever a person is needed. It never makes or changes a booking itself: requests go to your team to confirm.
Yes. The chatlyn platform is hosted in Frankfurt, and properties with stricter requirements can opt into EU-only AI processing. Data from your PMS flows one way into chatlyn, and marketing messages only go to guests who agreed to receive them.
