Google announced the removal in an official Google Workspace Updates post: Google Calendar SMS notifications to be removed January 7, 2019.
Google's current Calendar Help documentation describes reminders through phone, computer, browser, and email notifications, not native SMS reminders. See Google Calendar notification settings for the current notification options.
Before January 2019 - Google Calendar had an SMS notification option. It was part of Google Calendar's own notification system - a reminder sent to you through your Google account settings, not a client-reminder workflow for appointment businesses.
January 7, 2019 - Google removed SMS notifications from Google Calendar. Google said that people who had been receiving SMS notifications would instead get in-app/browser/mobile notifications and email notifications.
Since 2019 - Google Calendar still has notifications, but the current supported notification types are delivered on your phone, in your web browser, or by email. Google also says notification settings are personal to your account and do not determine notifications for other people who have access to the calendar.
| Notification type | Who receives it | Format | Sends client SMS? |
|---|---|---|---|
| Email reminder | Your own Google account | No | |
| Push / phone notification | Your own Google account | App / device notification | No |
| Browser / desktop notification | Your own Google account | Browser or desktop alert | No |
| Client SMS from Google Calendar | Your client | SMS | Yes, with a tool like Etisia |
No, Google Calendar cannot send native SMS or text reminders today. It can remind you, but client SMS needs a connected service that reads the appointment, finds the phone number, and sends the message outside Google Calendar.
| Service / path | Google Calendar integration | Best fit | Tradeoff |
|---|---|---|---|
| Google Calendar native notifications | Built into Calendar, but no native SMS channel | Personal app, browser, desktop, and email reminders | Does not text clients |
| Etisia | Connects to Google Calendar and sends client SMS reminders from events | Appointment businesses that want Google Calendar to stay the source of truth | Focused on SMS reminder workflows rather than replacing your booking software |
| Zapier + Twilio | Can connect Calendar triggers to SMS sending with custom setup | Technical teams that want flexible automation | More moving parts, plus template, opt-out, and reporting responsibility |
| Scheduling suites | Often sync bookings back to Google Calendar | Teams willing to move more scheduling into another platform | May not cover manual calls, walk-ins, or every existing calendar event |
For most Google Calendar-first appointment businesses, the practical replacement is a service that reads the calendar directly and sends SMS reminders without moving the team into a new scheduling system.
Use Google Calendar for the appointment and Etisia for the SMS reminder layer. The setup below keeps the calendar workflow intact while adding client-facing texts.
Sign in with Google, connect your Google Calendar, and turn the reminder workflow on. The whole replacement path is meant to feel faster than the old Google SMS setup ever did.
The calendar stays the source of truth. Etisia adds the reminder layer on top in one quick setup.
If the client is new, put the phone number directly into the Google Calendar event title. If the client already exists, Etisia can also work from the saved contact instead.
This is the fast path for one-off bookings and new clients.
For returning clients, save the contact once and future Google Calendar events can be matched by name. That means less typing, cleaner event titles, and a setup that gets easier over time.
Once the contact exists, you can keep using Google Calendar naturally without re-entering the number every time.
