Peptalkr uses the Marketing Promotion preference from your patient's profile to determine whether they are subscribed to promotional SMS.
If the SMS checkbox is ticked, they will receive SMS. If it's unticked, they won't.
However, we do offer you the option to bypass the opted in for marketing checkbox if you need to send essential SMS that is not promotional.
If a patient wishes to unsubscribe from promotional text messages they need to inform you and you'll need to update their settings in Cliniko.
