@Raine-and-Emberlie0 Well, no one is required to use scheduled and auto-reply messages. You could send more personal messages to guests, it depends on whether you want to spend the time to do that. I usually exchange a message or two with guests at the time they book, and we have often established a nice rapport like that. (Altho I'm a home-share host, so don't have faceless interaction with guests myself, which is why I've had my listing closed to bookings since last March, due to Covid).
Leaving a personalized card or note in the listing welcoming the guests, along with some chocolates or something like that. I.e. something that feels like you made a personal effort to be welcoming.
You seem like very experienced hosts, with 7 listings, and almost 1000 reviews, so I'm not sure what else I could suggest that you wouldn't already have thought of.
Do you check in with guests after they arrive to make sure they've settled in okay?
