Just spoken to a very helpful Sam, we are interested in sending a recall style SMS to invite patients in for an appointment approx 2 weeks in advance of their appointment that we would have booked for them. Not something that seems to be an option at the moment. Any help or ideas would be much appreciated.
This can be done using the appointment reminder system. I would also recommend that you set up a custom appointment type to book these appointments. That way when reminding patients about filling and denture appointments they are not going to get the same message that these exams booked without patients confirming are going to get.
I have recorded a short video of me going through the steps. If you have any questions please let me know.
