Reservation filters segment guests by the booking rather than the person: when they arrive, how long they stay, what they paid, which rate plan they are on. These are the filters that let a message land at the right moment rather than just reaching the right people.
Every filter has an Exclude selected option that inverts it, and filters combine with AND. See Audiences.
Arrival and departure
Guest checks in. A check-in date. The dropdown offers Exact, Between, After, and Before, then you pick the date.
Guest checks out. The same, on the departure date.
Guest check-in weekdays and Guest check-out weekdays. Days of the week rather than dates. Select one or more. This is how you separate the weekend break from the Tuesday business stay, which usually want different messages.
Estimated time of arrival. A time range, defaulting to the full day. Useful for a late-arrival message about how to get in after the desk closes, or for warning early arrivals that the room may not be ready.
The stay itself
Number of nights. Exactly, At most, At least, Between, or Any number. A one-night stay and a two-week stay are different guests with different needs.
Number of guests. Two separate fields, adults and children, each defaulting to any number. Filtering on at least one child is how you find families for anything from a kids' menu to a quieter room.
Properties. Which property or building the reservation belongs to. Essential once you run more than one.
Reservation set. Whether the booking is part of a linked group of reservations, such as a wedding party or a block booking.
How and when it was booked
Days booked ahead. Lead time, with a Min and an optional Max. Someone who booked eleven months out and someone who booked last night are at completely different points in their planning, and a pre-arrival sequence written for one reads badly to the other.
Reservation booked at. The date the booking was made, with the same Exact, Between, After, Before options. Use it to catch everyone who booked in a specific window, such as during a promotion.
Rate plan. The rate attached to the booking, chosen from your available plans. Room-only guests are the obvious audience for a breakfast upsell.
Rate plan code. The internal code rather than the display name, for when you have many variants and need to be precise.
Money and companies
Reservation balance. What is still outstanding on the booking. This is per reservation, and is not the same as Total spend, which covers a guest's whole history and lives in Audience filters: guest and profile.
Reservation debtor is company. Whether the bill goes to a company rather than an individual.
Reservation linked to company. Broader: any company association at all, regardless of who is paying. A guest can be linked to their employer while paying personally, which the debtor filter would miss.
Forms
Reservation has submitted form. Whether anyone on the reservation has completed a chosen form. Leave Exclude selected off for those who have submitted, turn it on for those who have not, which is the useful direction: it gives you exactly the people to chase for a pre-arrival form.
The guest-level equivalent, which asks about one person rather than the booking, is Guest has submitted form.
What this does not do
A filter on a field your PMS does not send matches nobody. Rate plan codes, estimated arrival times, and child counts are the usual gaps. An empty audience is often a missing field rather than a missing guest.
Reservation balance is not total spend. One is outstanding on a single booking, the other is lifetime value. They are in different articles for that reason.
These filters do not check reachability or consent. Add Reachable first, every time.
Cancelled reservations still exist. If a cancellation should not receive your message, exclude it deliberately rather than assuming it has gone.
What to do next
To narrow further by who the guest is rather than what they booked, see Audience filters: guest and profile.
