In addition to sending messages to guests though Airbnb's or VRBO's messaging platform you can also send automated email or SMS messages to your cleaners or managers. This is often used to let the cleaners know that you just got a new booking or to remind them a day or two before they need to clean.

When creating a message rule, simply select the Send as an email or the Send as an SMS option and enter the email or phone number you would like to send the message to.
