WhatsApp Template for Clinics: Appointment Reminder

WhatsApp appointment reminders reduce no-shows and improve communication with your patients. Here is a template you can copy and adapt, designed for clinics and doctor's offices.

• {{1}}: patient's name (e.g., Maria)
• {{2}}: clinic or specialty name (e.g., Clinica San Martin, dental office)
• {{3}}: appointment date (e.g., March 15)
• {{4}}: appointment time (e.g., 10:30)
• {{5}}: contact phone number to reschedule

1. 1Copy the template and replace the variables {{1}}, {{2}}, etc. with each patient's data.
2. 2In WhatsApp Business, go to Tools > Message Catalog and create a new message with this text (use the variables as custom fields).
3. 3If you use Wando, load the template in the panel and the AI will use it automatically when appropriate, always with your prior approval.

Message variants

This type of message is transactional (utility category in the official WhatsApp API). It does not require prior opt-in from the patient, but the template does need to be approved by Meta. Approval can take up to 48 hours, so load it in advance.

When to send this message (and when not to)

The ideal time is 24 to 48 hours before the appointment. At that distance, the patient still has room to reschedule, but the appointment is already fresh in their mind. Sending it a week before is forgotten; sending it two hours before creates anxiety and leaves no time to reorganize.

Do not send it if the appointment was confirmed the same day by phone or WhatsApp: the patient already knows, and the message is unnecessary. Also, do not use it for urgent or same-day appointments: in those cases, a reminder adds nothing and may be annoying.

If the patient has already rescheduled or canceled, do not send the reminder for the old appointment. This requires having your data synced with your calendar; if your system does not do it automatically, review the list before sending.

What to reply when the patient responds

The reminder does not end when it is sent: it starts when the patient responds. The three most common responses and how to handle them:

1. "Yes, I'll go": confirm and close the matter. No need to go back and forth.

2. "I can't": offer to reschedule right away. If you don't know the schedule, ask for the details and promise a quick response.

3. "I have a question": respond concretely and, if the question is clinical, refer to the appropriate person.

• Confirmation: "Perfect, {{1}}! We'll see you on {{2}} at {{3}} at {{4}}. If anything comes up, write to us here."
• Rescheduling: "No problem, {{1}}. Would you like us to find another time? Tell us which days work for you and we'll confirm here."
• Question: "Good question, {{1}}. I'll connect you with {{2}} who can answer better. Meanwhile, if you need anything else, let us know."

How to know if the message worked

The main metric is the no-show rate: compare unassisted appointments this month with last month. If it went down, the reminder is doing its job. You can also look at how many patients respond "I can't": that's a sign the message is being read and acted upon.

Another signal: how many reschedule. If a patient notifies and reschedules, it's not a lost no-show, it's a moved appointment. That counts as success, even if it's not an attendance.

In Wando, message and campaign statistics show you delivered, read, and responded. If you see many sent but few responded, the text may be failing: try the closest variant or change the sending time.

If the no-show rate doesn't change, check if the message reaches the correct phone. A patient who doesn't have WhatsApp on the registered number will never receive the reminder, no matter how good the template is.

Why Meta may reject the template and how to fix it

Meta approves utility templates if they are clear, transactional, and don't ask for anything unusual. The most common rejection reasons:

1. Disguised promotional content: if you include "Take advantage of 20% off your next visit!", Meta flags it as marketing and requires opt-in. Remove any promotional content from the text.

2. Poorly defined variables: if {{1}} is not explained or is used for different things in the same message, the reviewer doesn't understand and rejects it. Each variable must have a single meaning.

3. Text with errors or spam: all caps, repeated exclamation marks, or words in capital letters ("FREE") are red flags.

4. Lack of context: if it's not clear who sends the message and why, Meta rejects it. That's why the clinic's name must always appear in the text.

To fix it: adjust the text, remove anything unnecessary, redefine the variables, and re-upload. Approval can take up to 48 hours, so don't leave it until the last minute.

Message variants and when to use them

The base template is neutral: it works for most patients. But there are two variants that cover specific cases:

The formal variant (“Estimado/a {{1}}...”) is for patients who prefer a more distant treatment: older people, long treatments, or contexts where voseo doesn't feel comfortable. It also works if the clinic has an institutional tone, like a hospital or a specialist's office.

The friendly variant (“¡Hola {{1}}! 👋...”) is for clinics with a more familiar approach, like aesthetic or pediatric clinics, where the patient already feels at ease. It also works for young patients or for recurring appointments where there's already a bond.

Don't mix them: if the clinic is formal, the friendly variant can feel out of place, and vice versa. Choose one and keep it consistent across all reminders.

If you use Wando, the AI learns from your real responses and will suggest the variant that works best for each patient. You always have the final say.
