First trying searching forum topis. I have many posts concerning this subject. In the next patch I have added an email batch reminder for appointment notifications. I support fax RingCentral and etherFax. For SMS it’s RingCentral and Twilio. You can turn module in Manage Modules as this is a core module for our users. Only fees are RC or Twilio fees.
Also you’re welcome to add or fix module and I will be happy to help you get your mods in via a PR.
re: forgot a link Newly Improved Fax, SMS and Email Module
You can also send forms to patient to fill and send back for audit by user.
I look forward to any contribution/enhancements you come up with.
Good Luck
