Appointment Reminder sends automated SMS, email, and voice reminders to your clients based on your Google Calendar™ appointments. Add a phone number to any event and reminders go out on your schedule, with no manual effort.

Built for businesses, not personal use. If you run a practice, clinic, salon, or any appointment-based business, this add-on helps your clients show up by sending professional reminders before their appointment.

How it works: connect your Google Calendar™ , add your client's phone number to any event, and reminders are sent automatically by SMS, email, or voice at the times you choose. Clients can confirm, cancel, or reschedule by replying to the text, and their status is written back to your calendar.

Key features: automated SMS, email, and voice reminders; two-way messaging so clients confirm or cancel by reply; confirmation status synced to your calendar; custom templates with your business details; multiple reminder timings; multi-provider support; an online booking page for self-scheduling; and HIPAA-compliant workflows with a signed BAA available for healthcare practices.
