Automatically text appointment reminders from Google Calendar. Clients confirm or cancel by SMS. Plans from $19/mo, free trial included.
SMS Reminder is a Google Calendar integration that automatically texts clients before their scheduled appointments to reduce no-shows. Clients can confirm or cancel directly from the text or a linked page, and businesses can also let clients self-book appointments that sync straight into Google Calendar. Reminder timing is customizable (24 hours, 2 hours, or a custom interval before the event), and the service supports multiple calendars and users depending on plan, with SMS coverage in 100+ countries.
The product reports 786K+ installs from the Google Workspace Marketplace, 2,000+ businesses using the service, and over 5 million reminders sent. It targets appointment-based businesses (salons, clinics, consultants, and similar) that already run their scheduling through Google Calendar and want to cut down on missed bookings without adopting a full scheduling platform.
No permanent free plan. SMS Reminder offers a free trial covering up to 25 reminders; after that a paid plan starting at $19/mo is required.
