How do you use customer audiences?

The list of people who already booked is for not paying them again for the same search, or for an offer the floor can actually give them. It is not for chasing the whole neighbourhood with a discount ad that does not exist. Export emails or phones from real bookings, with permission, and remove staff. If the list is twenty people, it is not an audience. The whole diary is uploaded and the ad asks them to “discover” the venue where they eat every Friday. It annoys them and does not fill a gap. The list loaded to exclude people who already come, and the acquisition ad outside that list. An offer to past customers only if there is a weekday gap and an end date.
