LIVE DEMO
Choose a time, add a name and mobile number, and send a real test reminder before creating an account. The demo follows the same calendar-to-SMS flow that Etisia uses for eligible appointments.
SMS appointment reminders are automated text messages sent before scheduled appointments. Etisia creates them from appointments already in Google Calendar, helping clients remember without requiring the business to change how appointments are booked.
See it in action
Some clients call. Some send a text, WhatsApp message, or email. Others book while standing in front of you. Etisia does not force them through a new portal, so you can keep accepting appointments through the channels that already work for your business.
Add the appointment to Google Calendar as usual. Once the client details are available in the calendar event or a saved contact, Etisia handles the appointment reminder text. The appointment stays in the calendar your team already uses, while the repetitive reminder work runs in the background.
The booking can start anywhere. Etisia starts when the appointment reaches your calendar.
Etisia adds a reminder step after the appointment exists. You keep control of the schedule, choose the reminder settings once, and let each eligible calendar event move through the same clear process.
Learn how Etisia works with Google CalendarChoose the Google Calendar that contains your appointments and configure when reminders should be sent. You do not need to recreate upcoming appointments in a separate booking database.
Continue accepting bookings by phone, text, WhatsApp, email, walk-in, or in person. Add the client details to the calendar event or use a saved contact so Etisia can match the appointment to the right mobile number.
Etisia matches the client details, schedules the appointment reminder text, and sends it automatically at the configured time. You can check the reminder status without writing and sending every message yourself.
Clients receive a normal SMS. They do not need an app, Etisia account, or new booking portal.
The reminder arrives in the client’s existing SMS inbox. There is no app to download, account to create, or portal to learn. The message can include the appointment details and, when enabled by the business, a secure link for cancellation.
This is an outbound, one-way reminder. Clients do not confirm, cancel, reschedule, or start a conversation by replying. Need help with the wording? Browse appointment reminder text templates.
Each capability supports the same outcome: less repetitive reminder work for the business and a clear appointment reminder for the client. Etisia handles the mechanism while Google Calendar remains the source of the appointment.
Stop checking tomorrow’s appointments and sending the same message one by one. Choose when reminders should go out, and Etisia schedules the SMS automatically when an eligible appointment reaches Google Calendar.
Keep appointment reminder texts out of unsuitable hours. Etisia applies your configured quiet hours and the relevant time zone when it schedules reminders for eligible appointments.
Prepare reminders without maintaining a second appointment list. Etisia can match a mobile number from the calendar event or a saved contact connected to the appointment.
Check reminder status instead of guessing. Etisia helps you distinguish messages that are scheduled from those already sent and events that still need usable client details.
Make cancellation easier without an app or reply. When enabled, a secure link in the SMS lets the client cancel; Etisia then updates or removes the matching appointment and notifies the business.
Keep opt-outs separate from appointment actions. Supported keywords such as STOP opt the number out; they are not confirmations, cancellations, rescheduling requests, questions, or ordinary conversations.
Create a sample appointment and try the live reminder flow before signing up.
A client does not need to call or reply to the reminder to cancel. When a secure cancellation link is included, the cancellation can be handled through that link and reflected in the calendar where the business manages appointments. The link is optional and offers cancellation only; it does not turn the SMS into a two-way conversation or offer rescheduling by reply.
The client opens the secure cancellation link included in the appointment reminder text.
North Studio · Tomorrow, 10:00
The client cancels the appointment on the secure cancellation page, not by replying to the SMS.
Tomorrow · 10:00
Etisia updates or removes the matching Google Calendar appointment so the schedule reflects the cancellation.
The business is notified.
The business receives a cancellation notification and can handle the newly available time through its usual process.
Etisia begins after an appointment has already been booked. It does not ask every client to use the same booking page, and it does not replace the calendar your team already knows. The product has a focused job: turn eligible calendar appointments into automated SMS appointment reminders.
Etisia is a good fit for appointment-based businesses that already use Google Calendar and receive bookings through a mix of calls, messages, emails, walk-ins, and in-person conversations.
It is especially useful when the business wants automated appointment reminders without moving every client and employee into a full booking platform. The team keeps the schedule it knows, and clients keep using the booking channels they already choose.
These answers explain the reminder workflow, what clients receive, and where Etisia fits alongside Google Calendar.

Keep Google Calendar, keep the way clients already book, and let Etisia handle the reminder text.
