Unfortunately NO SHOWS are inevitable, even when taking all the possible actions to prevent them. Therefore it could be desirable to send a patient, that didn't show up to his/her appointment, an email, and SMS to inform them.
The context of this email or SMS is up to the clinic.
Sending No-show email and SMS
When marking an appointment as a NO SHOW there will be an option presented to send an email, SMS, or both to the patient.
Customizing No-show email and SMS
To customise the context of this email and SMS open menu > Clinic settings > Email & SMS settings > Appointments.
Next, scroll down and find No-show under the Appointments header and click it.
Customize the text in the following pop-up and click save.
