It is one of the most repeated questions in r/AirBnB and r/ShortTermRentals: “Can I just message my guests on WhatsApp instead of the app?” The short answer hosts give is yes, with one important condition. Here is the honest version, including the part about staying on the right side of Airbnb’s rules.
The short answer
Yes, you can message Airbnb guests on WhatsApp, once the reservation is confirmed. At that point Airbnb shares the guest’s phone number with you, and reaching them on WhatsApp for check-in details, directions, and support is completely normal. What you should not do is try to move the conversation off Airbnb before the booking exists, or push guests to pay or book outside the platform. Keep the booking and any payments on Airbnb, and use WhatsApp for the stay itself.
Why hosts want to in the first place
The reason is not complicated, and Reddit is blunt about it: guests do not reliably read the Airbnb app or their email. Hosts describe sending careful check-in instructions through the platform, then getting a call at the door because the guest never opened them. WhatsApp flips that. Messages are opened almost immediately, guests reply in a thread they already use all day, and the whole stay feels more personal. Fewer missed check-ins and fewer late-night “how do I get in” messages is the outcome hosts point to.
The rules worth respecting
To keep this clean and within Airbnb’s terms:
- Keep pre-booking conversation on Airbnb. Inquiries and negotiation stay on-platform.
- Never solicit off-platform payments or push guests to book direct to dodge fees. That is the line that gets accounts in trouble.
- Use WhatsApp for the guest experience, not to circumvent the platform. Welcome, directions, check-in, support, checkout.
Treated as a better delivery channel for a confirmed guest, WhatsApp is not a gray area. It is just where the message lands better.
How hosts make it automatic
The manual version is tedious: wait for the booking, dig out the phone number, save the contact, type a welcome. Hosts who do this at any scale automate it instead.
When your Airbnb booking syncs through a PMS (Smoobu, Lodgify, Guesty, Hostex), the guest’s phone number comes with it. Notify My Guest reads that number, fills in your template with the guest’s name and dates, and sends a WhatsApp welcome from your own number the moment the booking is confirmed. If a number is saved without a country code, it fixes it, and if a guest is not on WhatsApp, it tells you so you can reach them another way. For every message after the welcome, Mail2WhatsApp lets you send a WhatsApp from any platform that can send an email.
The bottom line
Can you message Airbnb guests on WhatsApp? Yes, once they are booked, and done right it is one of the highest-impact changes hosts make to their guest experience. Keep the booking on Airbnb, move the stay to WhatsApp, and automate the whole thing so it happens on every reservation without you lifting a finger.
