How many no-shows WhatsApp appointment reminders save you, and what they should say

Diana runs a massage and facial spa in Chetumal. Until September, she sent the appointment reminders on WhatsApp herself. At night, after closing the spa, she’d copy down the next day’s appointments from her notebook and text each client from her phone. On nights she left the treatment room late, she’d forget, and the next day someone wouldn’t show up.

In September, twelve appointments fell through. Seven of those clients wrote to her afterward, apologetic: they’d forgotten, or thought it was a different day. Three told her something had come up and they hadn’t known how to cancel without feeling bad about it. Two never answered. That count told her exactly what her message needed to do: remind the seven, and give the three an easy way to let her know.

What is an appointment reminder on WhatsApp?

An appointment reminder on WhatsApp is the message your client gets before her appointment, telling her what she’s booked, when, and where, and asking if she’s still coming. The confirmation is a separate message: it arrives the moment she books, with two buttons, “Reschedule” and “Cancel appointment.”

In Proyecta both are turned on automatically as soon as your page has a booking calendar, and they go out by email and WhatsApp, at no cost. The WhatsApp message goes out under your spa’s name from Proyecta’s notification line, and starts going out once you publish your page. It reaches every client who left her WhatsApp number when booking, and also the ones you enter under New appointment with their phone number. Below her details, your page lets her know that’s where her confirmation and reminder will arrive.

How many no-shows does a reminder save you?

It saves you the ones caused by forgetting, and thanks to the buttons, many of the ones who didn’t feel comfortable texting turn into a timely heads-up instead. The client who simply doesn’t want to come anymore won’t be stopped by any message.

In Diana’s September, that meant seven no-shows a reminder would have prevented, three that could become a timely heads-up, and two with no fix. Your numbers will be different, which is why it’s worth counting them yourself before trusting a percentage. If almost all your no-shows come from forgetting, a reminder is the first thing you need. If almost all of them come from clients who never answer, what helps is asking for a deposit.

What should the message say so your client actually shows up?

Five things: who it’s from, what service she booked, the day and time, where it is, and a question she can answer with one tap. Miss any of them, and your client has to message you to ask, and many won’t.

This is how the reminder for her facial reached Alondra, one of Diana’s clients:

Hi Alondra, we’re writing on behalf of Spa Diana to remind you of your appointment: Deep Facial, on Friday, November 6, 5:00 p.m.

We look forward to seeing you at spa’s street and number. Directions: map link

Will you be able to make it? Confirm it with the button, or reply to us here if you need to change it.

Below it, there are three buttons: “I’ll be there,” “Reschedule,” and “Cancel appointment.”

That text is fixed, because WhatsApp only lets a business message first using pre-approved templates. You can see it under View message, under “How your client receives it,” with sample data filled in. What does depend on you is the data that fills it in:

1. The service name appears exactly as you have it set up in your calendar. “Deep Facial” is clear; “Sak Nikté Ritual” forces her to ask what that was.
2. The address comes from Schedule, Locations, on the “Your location” card. If that only says “Chetumal,” the reminder goes out without the “Directions” line.

The reminder email carries the same information, with the address linked to the map and a button that says “Yes, I’ll be there.”

How far ahead should it arrive?

One day ahead works for almost everything, and that’s how it comes by default: “24 hours before.” It gives your client time to work it into her day, and if she can’t make it, it gives you time to offer that slot to someone else.

You can also send it 1, 2, 4, 12, or 48 hours ahead. And three rules apply on their own. No reminder goes out before 8 a.m., in your business’s local time. If your client books with less lead time than your reminder window, that reminder simply doesn’t go out, since she just got the confirmation. And two reminders never arrive less than an hour apart.

The second rule changed Diana’s plan. Many of her clients book at night for the next day, and the 24-hour reminder would never reach them. She turned on the Second reminder, set to “2 hours before,” which goes out with the same text.

What happens when your client taps a button or replies?

If she taps “I’ll be there,” her appointment gets marked in your calendar: in the list it says “Client confirmed,” and on the calendar it carries a small icon with that label. If she confirms from the email with “Yes, I’ll be there,” it’s marked the same way.

If she taps “Reschedule” or “Cancel appointment,” or if she writes in the chat, your business’s assistant replies to her in that same conversation. It repeats back which appointment it’s about, waits for her yes, and then moves or cancels it, and you get the notification.

That’s where the three who didn’t know how to let her know come in, because typing “I can’t make it anymore” takes effort, and tapping a button barely does. In the first week, one client canceled her Saturday 11 a.m. massage on Friday at 6 p.m. Diana messaged another client who always asks for a Saturday slot, and the opening got filled.

Where do I turn it on, turn it off, or change the timing?

In your dashboard, under Marketing, Automations. You can also get there from the Schedule: under Settings there’s “Automatic messages to your clients,” with a Go to Automations button.

In the “About their appointments” group you’ll find Appointment confirmation, Reminder, and Second reminder. For both reminders you choose the “When?” setting, and for all three you have the Also by WhatsApp toggle, in case you want any of them to go out by email only. The same screen sums it up at the top: “All of them go by email. The confirmation and the reminders also go by WhatsApp. All at no cost.”

How do I set this up for my spa?

Describe your business to Proyecta in your own words. Something like: “a page for my massage and facial spa in Chetumal, with 60- and 90-minute relaxing massage, deep-tissue massage, deep facial and facial cleansing, each with its price and duration, online booking, my location’s address with a map, and a WhatsApp button.”

Once your page is published and the calendar is taking bookings, the confirmation and the reminder go out on their own.

And this week, to every client who misses an appointment, send just this: “Did it slip your mind, or did something come up?” With a month of answers, you’ll know how many of your no-shows a reminder can fix. Get started at proyecta.dev.
