Hotel Booking Nulled Event-Driven Emails This extension allows you to create common event-driven emails/notifications, such as key pick-up instructions or house rules, before and after arrival/departure. Upsell services or offer property upgrade options by sending relevant pre-arrival emails. Ask for property reviews to get social proof in a certain number of days after check-out. Send any other type of automated relevant emails to drive ancillary revenue. Less work for a manager, a receptionist or a housekeeper.
