A no-show is worse than a cancellation: the slot sits empty and nobody else could have taken it. It hurts most where every hour is booked, like physio clinics and tuition centres. A short, well-timed WhatsApp reminder is the simplest fix. Here are five messages you can copy today.
When to send reminders
- The evening before — the main reminder. Early enough to reschedule, late enough to remember.
- Two hours before — for longer or paid appointments, a short nudge.
- Right after booking — the confirmation, so the details are in writing from the start.
Five messages to copy
1. Booking confirmation
Hi Lakshmi, you're booked for a cleaning on Sat 31 Oct at 5:00 pm with Dr. Arun at Smile Care Dental. Reply here if you need to change it.
2. The evening-before reminder
Hi Lakshmi, a reminder of your cleaning tomorrow at 5:00 pm with Dr. Arun. Tap Confirm, or Reschedule if the time no longer works.
3. Two hours before
See you at 5:00 pm today, Lakshmi. Parking is free behind the clinic.
4. When they cancel
No problem, Lakshmi — your slot is cancelled. Would you like the next free time? Dr. Arun has Monday at 6:00 pm.
5. Filling the gap (to someone on your waitlist)
Hi Ravi, a 5:00 pm slot just opened today with Dr. Arun. Would you like it? Reply Yes and it's yours.
What makes a reminder work
- Use their name and the exact time. “Your appointment” is easy to ignore; “tomorrow at 5:00 pm” isn't.
- Give one-tap answers. Confirm and Reschedule buttons get replies; open questions get silence.
- Make rescheduling easy. A customer who can move the slot won't simply not turn up.
- Refill the slot. A cancellation is only a loss if the slot stays empty.
Doing it without doing it
Sending these by hand works for a few bookings a day and falls apart on a busy week. Anssay sends the confirmation, the evening reminder and the waitlist offer on its own, from your Anssay number, and reschedules when the customer taps the button. A customer can reply STOP anytime and won't get another. Reminders use WhatsApp credits, and every plan includes 500 a month.
