How to Send WhatsApp Reminders for Appointments Automatically

WhatsApp appointment reminders are the single most useful message a booking system sends, because the client actually reads WhatsApp. Typing them by hand each evening is how most creators do it, until they forget one. Viralyze sends the reminder automatically for every booking made through your link, using the number the client entered when they paid. This article covers what the reminder does, how it fits with confirmation and rescheduling, and how to set it up.

Do I need a WhatsApp Business account or chatbot for this?

No. Reminders are part of bookings in Viralyze and run without any WhatsApp setup on your side. You do not need to install anything, create templates, or manage a broadcast list.

This is separate from the WhatsApp chatbot on the Pro plan, which is coming soon and is meant to answer FAQs and book slots. Reminders are included in bookings on every plan, including Starter at ₹199 a month.

What does the client receive?

The client receives a booking confirmation and a reminder before the appointment on WhatsApp, alongside the confirmation page where they can add the session to their calendar, reschedule, or cancel if you allow it.

A nail artist in Chandigarh, for example, takes bookings for a "Gel extensions, 90 minutes, ₹1,800" service. Her clients get the reminder before the appointment, and the ones who cannot make it reschedule from the confirmation page instead of messaging her at 11 PM.

How do you set it up?

There is no reminder setup to speak of; you set up bookings and the reminders come with them.

1. Create your services with duration, price and format. 2. Connect Google Calendar and set buffers and days off. 3. Decide whether clients can cancel or reschedule themselves and until when. 4. Share the booking link in your bio and through your Auto-DMs.

From the first booking onward, confirmation and reminders go to the client's WhatsApp automatically.

Does the reminder reduce no-shows?

In our experience, yes, especially combined with upfront payment. The reminder catches the "forgot" cases, and the paid slot catches the "changed my mind" cases.

The reminder also lands before your cancellation cut-off for most sensible windows, so a client who sees it and cannot attend still has time to cancel or reschedule, which reopens the slot for someone else and triggers the automatic refund if you allow it.

Can the reminder include the Meet link or address?

For Google Meet sessions, the Meet link lives in the calendar invite the client receives, and the confirmation page links to the booking details. For in-person sessions, put the address in the service description so it appears with the booking details.

Keep the service description short and practical: where to come, what to bring, your cancellation rule. That text does more for attendance than any extra message would.

Frequently asked questions

**Can I send a custom reminder message?** Reminders are sent automatically with the booking details; use the service description for any instructions you want the client to see.

**What if the client gave the wrong number?** The reminder goes to the number entered at booking, so ask clients to double-check it; the confirmation page is also available to them from the booking.

**Do reminders go for free bookings too?** Yes. Any booking made on your link, paid or ₹0, gets confirmation and reminders.
