Add Guest Sentiment at checkout (from Rezzy), to be used as a trigger for messaging. Here is my use case scenario:
I have a setup where a message I send to guests after check-out asks for their review, unless the guest had problems during their stay, in which case the message is not sent; when I know a guest had problems, in my ERP, I flag the booking (as "Guest Had Problems"), that setups the booking with a "Guest Had Problems" tag in OR via an API call, and that makes the OR message requesting the review not to be sent (using the Tag condition in the Trigger setup).
