## Your UK clients get text reminders from your Google Calendar

Put your client's mobile number in their Google Calendar booking and Etisia sends them a text before they arrive. Nothing else changes about how people book with you.

## A text reminder service that works from your Google Calendar

Etisia is a text reminder service for UK businesses that adds SMS reminders for Google Calendar: once a booking holds the client's mobile number, Etisia texts them ahead of the appointment. The text is for your client, not for you, and it's one-way, so they can't reply to it. Adding a cancel link is up to you. The trial runs for 21 days without a card, then Starter costs £16/mo ex VAT, billed yearly.

### In brief

- **The recipient:** Your client, as a normal text on their own phone. There's no app to download and nothing to sign up for.
- **Finding the number:** Etisia picks it out of the event: title, description, location or guests. Once a client is saved, their full name alone is enough.
- **Replies and cancelling:** Clients can't reply; the reminder is one-way. Turn on the cancel link and they can cancel online instead.
- **What you pay:** £16/mo ex VAT, billed yearly on Starter after the 21-day trial, and no card details are needed up front.
- **Getting started:** Make an account here, then connect Google Calendar once. Then carry on booking as normal; the reminders send themselves.

## Three steps to text reminders from your Google Calendar

1. **Link the Google Calendar you take bookings in** - Log in with Google and tick the calendar your appointments go in. It can be your own or one you've been allowed to edit; Etisia ignores the rest.
2. **Give the booking the client's mobile number** - Write it into the booking's title or description, beside their first and last name. Etisia saves the pair as a contact; after that, the full name is enough. [More on adding numbers](https://www.etisia.com/google-calendar/add-client-phone-number)
3. **A text goes out before they arrive** - Unless you change it, the text is sent the day before. Every plan lets you set up to 3 reminder times, anything from 15 minutes to a month beforehand ([choosing reminder times](https://www.etisia.com/google-calendar/set-reminder-timing)). Quiet hours come switched on, so no texts go out overnight (22:00 to 07:00); one due then is brought forward to about 20:00. In the event title you'll see “(SMS ready ✅)” and, once it has gone, “(SMS sent ✅)”.

## What lands on your client's mobile

They get the day, the time on a 24-hour clock and your sign-off, usually your business name. Below is the standard wording for a 15:30 appointment tomorrow, cancel link off.

> Hello, you have an appointment with us tomorrow, October 8, 2026 at 15:30. Best regards, Bramley Skin Clinic

- **An ordinary text.** It sits with their other messages, so there's no app or account for them to bother with.
- **Cancelling is up to you.** Turn it on and the text ends with “Cancel at” and a short link. Your client opens it, types in the number the reminder came to and taps the cancel button. The booking then leaves your Google Calendar and Etisia emails you.
- **No texting back.** UK reminders are sent under a sender name, not from a mobile number, so there's nothing to reply to. Clients who need to rearrange ring you.
- **Change the wording if you like.** Stick with the default, pick a different ready-made reminder or write your own wording. Day and time are added for you.

## It doesn't matter how the booking was made

Whether a client rings, messages, walks in or books through a tool that writes into Google Calendar, Etisia treats the booking the same. A Google Calendar appointment in a connected calendar, carrying the client's mobile or a saved contact's full name, gets its reminder. It suits sole traders and small teams, from mobile hairdressers to driving instructors.

### The number can be in

- the booking's title
- the description, the location or the guest list
- a saved contact with the same full name

### No reminder is sent if

- Etisia can't find a usable number (the title says so)
- the number is from outside the UK
- it's marked as an all-day event
- the calendar it's in isn't connected
- it's deleted before the send time
- your plan has no texts left for the month

## What you'll pay in the UK once the trial ends

The first 21 days are free and need no card, and no payment is taken unless you subscribe. Up to 60 free SMS land in your account while you complete the setup steps. After that, Starter is £16/mo ex VAT, billed yearly and Pro is £28/mo ex VAT, billed yearly.

|  | Starter | Pro |
| --- | --- | --- |
| /month (Billed yearly) ex VAT | £16 | £28 |
| Monthly ex VAT | £19 | £33 |
| Yearly ex VAT | £190 | £330 |
| Google Calendars | 1 | 3 |

You can stop your plan at any time. More calendars or a bigger team? [All UK plans](https://www.etisia.com/gb/pricing).

All prices are in pounds sterling, for businesses based in the UK.

## Other ways to send clients a reminder

Google Calendar has no way to text a client, so people tend to use one of these. Booking software may already send reminders, so check its settings first.

|  | Texting each client yourself | Online booking software | Etisia |
| --- | --- | --- | --- |
| Where bookings are kept | Wherever you keep them now | Inside the booking software | Your own Google Calendar |
| Getting started | Nothing, but every text is sent by hand | Clients and staff switch to new software | Connect your calendar once |
| Replies | Straight to your own phone | Depends on the software | One-way; cancelling by link if you allow it |
| Paying | Your time and your phone bill | A monthly fee, often for many extra features | From £16/mo ex VAT, billed yearly |

## Common questions from UK businesses

### Won't Google Calendar send my clients a text on its own?

No. Its reminders are for you, as pop-ups and emails, and Google switched off its SMS notifications on 7 January 2019. [What Google's built-in reminders can do](https://www.etisia.com/google-calendar/can-google-calendar-send-text-reminders)

### Can I try it before I pay?

Yes: you get 21 days and aren't asked for a card. Then choose a paid plan or stop; there's no free tier.

### Does it work with UK mobile numbers?

Yes. A UK account texts UK numbers, typed into the event title or description as you'd normally write them. A number with another country's dialling code isn't texted.

### Will my clients be able to reply to the text?

No, it's one-way, with no number to reply to. If the cancel link is on, they can cancel by typing in their mobile number; to change the time, they contact you.

### I've moved a booking in Google Calendar. Does the reminder follow it?

Yes, if it hasn't been sent yet. Delete the booking and nothing goes out, because Etisia checks it again just before sending.

### How much is it after the trial, and is VAT included?

No, every price here is ex VAT. Starter is £19/mo ex VAT, billed monthly, or £190 ex VAT if you pay yearly. Pro is £33/mo ex VAT, billed monthly, for up to 3 calendars. No card is asked for until you subscribe.

### Do clients have to download anything?

No. The reminder is a standard SMS that any mobile can receive, with no app and no sign-up.

### Which Google Calendars can I connect?

Any calendar your Google account owns or is allowed to edit, Google Workspace calendars included. Ones you can only view won't connect. Starter takes one calendar and Pro up to 3.
