@Julie6722 I provide an emergency email address and a phone number to my guests. BUT that email address is my business email as is the phone number. It is NOT my personal email or phone number. Guests are also advised as to the business hours when I can be reached, which is generally 8 am to 8 pm. I do read their emails and texts after hours but will only respond in the case of a dire emergency (and there have been a few).
I provide the email and phone number so that guests will reach out to me before trying to obtain help from AirBnB CS. If you are comfortable with the AirBnB messaging, tell your guests that that is how they can reach you.
