No app, no account. - **Where the number comes from:** The event title or description, or a saved contact when the event has the client's first and last name. - **What the client can do:** Cancel with the optional link. Texts are one-way; in the US, replying STOP opts out. - **What it costs:** $12/mo billed yearly on Starter, after 21 days free. Up to 60 free SMS as you set up, and no card to start. - **How to start:** Sign up here and connect your Google Calendar once. Then set it and forget it: you book as usual, and the reminders go out on their own. ## How the Google Calendar SMS integration works 1. **Connect Google Calendar** - Sign in with Google and pick the calendar your appointments are in. Etisia only uses the calendar you select. 2. **Add the client's number to the event** - Type it in the event title or description. Include their first and last name so Etisia can save the contact. Next time, their first and last name is enough. [How to add a client phone number](https://www.etisia.com/google-calendar/add-client-phone-number) 3. **Etisia texts the client at the time you choose** - Pick when it goes out, from a month to 15 minutes before; the day before is the default. Up to 3 reminder times on every plan ([reminder timing](https://www.etisia.com/google-calendar/set-reminder-timing)). The event title shows “SMS ready ✅”, then “SMS sent ✅”. No number on an event? The title says so. Step-by-step screenshots are in the [setup guide](https://www.etisia.com/google-calendar/how-to-add-sms-reminders). ## What your client receives: an ordinary text message Your business name, the day and the time, from a US phone number. This is the text Mia gets the day before her appointment. > Beauty Studio: Hello, you have an appointment with us tomorrow, October 8, 2026 at 03:30 PM. Reply STOP to opt out. - **Nothing to install.** No app, no account and no calendar invite for the client. - **A cancel link, if you switch it on.** The text then ends with “Cancel at https://eti.is/…”. The client taps the link, types their phone number and taps Cancel. The appointment comes off your Google Calendar and you get an email. - **One-way.** Clients can't confirm, reschedule or chat by replying. If plans change, they use the cancel link or call you. - **STOP opts out.** In the US, texts come from a phone number, and clients can reply STOP to stop your texts. - **Your wording.** Pick a ready-made text or write your own. The day and time fill in automatically, and the location if you want it. ## Works with any Google Calendar appointment that has a number A phone call, a text, a walk-in, or a booking another tool writes into Google Calendar: once the appointment is in the calendar you connected, with the client's number or the full name of a saved contact, Etisia can remind them. Calendars you own or can edit both work. ### Etisia finds the number in - the event title - the description, location or guest list - a saved contact, by first and last name ### No text goes out when - Etisia cannot find the client’s number (the event title says so) - it's an all-day event - the event is in a calendar you didn't connect - you delete the event before the reminder time - your plan's SMS for the month are used up ## What SMS reminders cost: $12/mo billed yearly, and 21 days free to start Try Etisia free for 21 days, with no card.

Not as texts to your clients. Google Calendar's free reminders are emails and app alerts for you. Etisia has no free plan, but you can try it free for 21 days with no card; after that, Starter is $12/mo billed yearly. ### Can I send SMS reminders to my clients from Google Calendar? Yes, with a service like Etisia. Add the client's number to the event, and Etisia texts them at the time you choose. ### Does Etisia send reminders to me or to my clients? To your clients, at the number on the event. For reminders to yourself, Google Calendar's own notifications are enough. ### Where does Etisia find my client's phone number? In the event title or description; Etisia also checks the location and guest list. When an event has a number and a full name, Etisia saves the contact, so next time the first and last name is enough. You don't invite the client to the event. If there's no number, nothing is sent and the title says so. ### Can clients confirm or reschedule by replying to the text? No. The texts are one-way. With the cancel link on, the client taps it, types their phone number and taps Cancel. To move an appointment, they contact you as usual. In the US, replying STOP opts them out of your texts. ### How much do SMS reminders for Google Calendar cost? Starter is $15/mo billed monthly for 100 SMS, or $12/mo billed yearly. Pro is $27/mo billed monthly for 250 SMS and 3 Google Calendars. You add a card only when you choose a plan, and you can cancel anytime. ### Do I need a scheduling app to send text reminders? No. If your appointments are already in Google Calendar, Etisia texts from them. It isn't a booking system, so clients keep booking the way they do now. ### Does it work with Google Workspace calendars? Yes. Sign in with the Google account that owns the calendar with your appointments, or can edit it. Etisia is also on the Google Workspace Marketplace, and admins can check the details on our [page for administrators](https://www.etisia.com/google-calendar/for-administrators).
