Appointment reminder messages for WhatsApp: 14 templates for the day before, the morning of, confirm-or-reschedule, and clinics, salons, workshops and tutors
Most no-shows are not rudeness; they are forgetting. A short reminder the day before, with the time, the place and a way to reschedule, removes most of them. Here are the messages, timed, with versions for the businesses that book the most appointments.
Quick answer
Send one reminder 24 hours before with the service, time, address and a one-line reschedule option, and for high-value or long appointments a second brief one two hours before. Include your late or cancellation policy in a clause, not a paragraph. A confirm-or-reschedule line ("Reply 1 to confirm, 2 to move") turns a reminder into a commitment. ReplyKit sends the 24-hour reminder automatically for every booking the agent or you make, and the agent handles the replies, including moving the slot.
Timing
Research on appointment reminders, including the Cochrane review of mobile messaging reminders in healthcare, finds that a reminder improves attendance compared with none, and that timing a day ahead works well because it leaves time to reschedule. A second reminder two hours before helps for long or prepared appointments. Three reminders annoy. The wider approach is in reducing no-shows with reminders.

Sending them automatically
In ReplyKit every booking, whether the agent made it or you added it in the dashboard, gets the 24-hour reminder sent automatically on the number the customer used, with your policy line if you set one. Replies come back to the agent: "can I move it to Thursday" is answered with real open slots and the booking moves; "what should I bring" is answered from your knowledge. The reschedule handling is in rescheduling and cancellations, and the confirmation wording in the confirmation templates. Reminders are system messages and do not count against your reply allowance.
Frequently asked questions
When should I send an appointment reminder?
24 hours before, with the time, address and a reschedule option. A second short one two hours before for long or prepared appointments.
Should the reminder include my cancellation policy?
Yes, as one clause: "changes with less than 24 hours' notice forfeit the deposit." Not a paragraph.
Does a confirm-or-reschedule line help?
Yes. Asking for a reply turns a reminder into a commitment and surfaces reschedules early enough to refill the slot.
Can an AI agent send reminders?
ReplyKit sends the 24-hour reminder automatically for every booking and the agent handles the replies, including moving the appointment.
Do reminders count as AI replies?
No. They are system messages and are free.
