While each OTA platform - Airbnb, Vrbo, and Booking.com - share similar rules and standards, they have their own regulations regarding specific language that can be used in messaging. If your messaging rules contain information, words, or phrases that we know to possibly be in breach of their rules, we'll display a message like this:

The message states which platform may reject the message and the term that may cause it (in brackets). In the example above, Vrbo may reject the message due to the mention of Airbnb.

While this doesn't guarantee that your message will be blocked, we suggest reviewing your message and removing any potentially offending content.

Some terms may be censored, while others may cause your message to be rejected entirely. Below is a list of terms that we are aware of that could cause your message to be rejected:

To be able to send website links in your messages to Booking.com guests, you must first “whitelist” those links with Booking.com.

Any links that have not been whitelisted on your Booking.com account will cause the message to be blocked by the platform.

You can read all about how to whitelist links on Booking.com, here.

Platforms don't allow sharing personal information before a reservation is accepted. You should be fine for messages after the reservation is accepted, such as your Check-in instructions.

Phone numbers may be able to be sent if separated by periods i.e. 123.456.7890, but we recommend following platform rules to avoid penalties.

This breaches most platforms' policies and can result in your account being suspended. While certain phrasing can bypass their filters and be delivered, consider if this is worth the risk!
