Missed appointments are the most expensive recurring problem a clinic has: the slot cannot be resold, the clinician is paid regardless, and the patient still needs treating later. A reminder text is the cheapest known fix, and it runs from the WordPress site you already have.
Start here: read this before you send anything
Healthcare messaging is regulated, and the rules are stricter than in any other sector on this site. Treat the following as non-negotiable.
- Never put clinical detail in a text. No diagnosis, no test results, no treatment names, no consultant specialism. A message visible on a lock screen is not a private channel.
- In the US, SMS involving protected health information falls under HIPAA. That means a Business Associate Agreement with your gateway provider and a documented assessment. Not every provider will sign one. Confirm before you build.
- In the UK and EU, the same data is special category data under GDPR and needs a lawful basis and a documented retention policy.
- Get consent to contact by SMS explicitly and record when it was given.
A safe reminder says who it is from, the date and time, and how to cancel. Nothing about why the patient is coming in.
The messages worth sending
- Appointment confirmation at the point of booking.
- Reminder 24 to 48 hours ahead, with a way to cancel or rebook. Making cancellation easy is the point: a cancelled slot can be refilled, a no-show cannot.
- Prescription or repeat collection ready.
- Recall reminders for routine check-ups, kept generic.
Setting it up
- Choose a gateway that meets your regulatory requirements, not just your budget. In the US that means one willing to sign a BAA.
- Capture the number and the SMS consent in your booking form.
- Template the reminder so no free-text clinical note can accidentally reach a message body.
- Test the cancellation path end to end before going live.
