Appointment Reminders
Fewer empty slots.
A reminder only works if it is read, and if changing the booking is easier than not turning up.
The problem
A missed appointment costs the whole slot, and for most booking-based businesses that time cannot be resold at short notice. Reminders by email are rarely opened; SMS is read but dead-ended, so a customer who cannot make it has no easy way to say so and simply does not arrive. The gap is not that people forget — it is that cancelling is more effort than ghosting. A reminder someone can reply to turns a no-show into a reschedule.
How it works
Set it up once. Then leave it running.
-
Booking made
The confirmation goes out immediately with the date, time and location, so the details are in a thread they can find again.
-
Reminder before the day
A reminder lands far enough ahead that the slot can still be refilled if they cannot make it.
-
They confirm or move it
Confirming or rescheduling happens by replying. The reply reaches a person who can actually change the booking.

Make cancelling easy
It sounds backwards, but the fastest way to reduce no-shows is to make cancelling almost effortless. Most people who miss an appointment knew in advance; they just had no frictionless way to say so.
An invitation to reply with a better time converts a lost slot into a moved one.
Send it when it is still actionable
The timing question is not “when will they read it” but “when could we still fill the slot”. That usually means the day before, with a short same-day nudge as a second step.
Put the details in the thread
Because it lives in WhatsApp, the confirmation is still there on the day — address, time, and anything they need to bring. That alone removes a category of phone calls.

Frequently asked questions
How far in advance should the reminder go out?
Far enough ahead that you could still fill the slot if they cancel — for most businesses a day before, with an optional same-day nudge. A reminder sent an hour before prevents lateness but not the empty slot.
Can customers reschedule by replying?
Yes, and this is where most of the benefit comes from. The reply reaches a person in the shared inbox who can move the booking, which converts what would have been a no-show into a filled slot on another day.
Are reminders billed as marketing messages?
No. Appointment reminders are utility conversations under Meta's pricing, which is charged at a lower rate than marketing. The exact rate varies by country.
