Stop Client No‑Shows with Automated SMS Appointment Reminders

Etisia sends automatic SMS appointment reminders from your Google Calendar. After a one-time setup, you keep booking in Google Calendar as usual, with the client’s mobile number in the appointment. You don’t open Etisia each time you book.

Your clients get an ordinary text message: no app and no account. Etisia isn’t a booking system, so clients keep booking with you the way they do now.

Probably not, if your booking system already texts your clients. Etisia is for businesses that keep their appointments in Google Calendar, and for those still using pen and paper.

Still using pen and paper? Etisia is an easy first step. Keep your appointments in a free Google Calendar and write the client’s full name in each one, plus their mobile number the first time. That’s all Etisia needs, and your calendar gets tidier for it: every appointment shows who’s coming. The reminders go out in the background, so there’s nothing to open or send each day.

If your booking tool copies appointments into Google Calendar with the client’s mobile number in the event title, description or location, Etisia can send reminders from those events. Switch off the tool’s own text reminders, so clients don’t get two.

There is no direct connection to booking systems: Etisia only reads Google Calendar.

Sign up with email or Google, connect Google Calendar (tick both calendar permissions), pick your appointment calendar, and choose Default settings or set your own times and wording. Tick the box to say you have your clients’ permission, and you’re done.

Default settings send one reminder the day before, with recommended wording that names your business.

Then use Add test appointment: Etisia adds an appointment with your name and number to the calendar and texts you its reminder straight away, free.

Etisia works with free personal Google accounts and Google Workspace. You can connect calendars that account owns or can edit (“Make changes to events”). Read-only, holiday and subscribed calendars aren’t listed. If a Workspace admin blocks outside apps, use a personal account.

Only Google Calendar is supported: no Outlook or Apple Calendar.

Appointments in a different Google account? Disconnect Google in your profile and connect the other one. You don’t need a new Etisia account.

Type the client’s name and mobile number in the appointment title, for example “Sarah Jones (201) 555-0123 Haircut”. Etisia also looks in the description, the location and guests’ names.

You only type a number once: Etisia saves the client to your Contacts, so next time “Sarah Jones” is enough. A first name alone won’t match, and neither will two saved clients with the same name. You can also import contacts from your phone.

Two numbers in one event? Label the mobile one, for example “mobile: …”.

Etisia is available in 11 countries: the US, the UK, Australia, Ireland, Slovenia, Germany, Austria, Croatia, Spain, Poland, and Portugal. The app and texts are available in English, Slovenian, German, Croatian, Spanish, Polish and European Portuguese.

Reminders go to mobile numbers from your own country. For a client with a number from another Etisia country, write it with + and the country code: our team checks each appointment with such a number before its texts go out, so add these appointments in good time. Other countries can’t be texted, for example France or New Zealand.

Yes. Once a calendar is switched on, appointments already in it get their reminders automatically, with nothing to re-enter.

If a reminder’s time has already passed, it can still go a little late, and a day-before reminder still goes while the appointment is at least 12 hours away. Example: you finish setup at lunchtime. A client booked for 9 tomorrow morning gets the day-before reminder straight away; a client booked for 6 this evening doesn’t, but a 1-hour reminder would still go.

The booking message only goes to appointments added after you switch it on.

Yes. Etisia handles each repeat as its own appointment with its own reminders. Put the client’s number in the recurring event, and every visit in the series is covered.

To change just one visit, edit that occurrence rather than the whole series.

No. Reminders go only for appointments with a readable mobile number (or a saved client’s full name) in calendars you switch on. All-day events, out-of-office and focus-time blocks, invitations you declined and events without a title are skipped.

Etisia doesn’t judge whether an event is a client appointment, so a personal event with a number in it, such as your plumber’s, gets a reminder too. Keep private appointments in a calendar you don’t switch on.

You can pause a calendar or cancel one reminder in Etisia without deleting the appointment.

Yes. Etisia’s Starter plan covers one calendar, Pro three and Team as many as you need. Each calendar has its own reminder times and wording, so you can keep one per team member or service.

Team also adds staff accounts: you invite staff by email, they connect their own calendars and share the team’s SMS credits, and you can see and edit their calendars.

With the recommended wording, a US client gets: “Glow Studio: Hello, you have an appointment with us tomorrow, October 15, 2026 at 2:30 PM. Reply STOP to opt out.” Your business name and the STOP line are on every US text.

You can pick another template or write your own (up to 1,600 characters). Etisia fills in the date and time, and can add the appointment’s location. The client’s name isn’t included, which keeps texts discreet on a lock screen.

Each calendar has one wording; the preview shows the finished text before you save.

Every Etisia plan includes up to three sending times per calendar, for example the day before and two hours before. The booking message counts as one of the three.

Choose 15 minutes, 1, 2 or 6 hours, 1 or 2 days, 1 week, 10 days or 1 month before, or the morning of the appointment (about 8 am; for appointments before 10 am, about 8 pm the evening before).

Texts go out within about 15 minutes of the chosen time, quiet hours can move late-night ones, and each text uses SMS credits.

Yes, with the optional booking message. About two minutes after you add a new appointment with a start time, Etisia texts the client its date and time. The short wait gives you time to fix a typo. If the cancellation link is on, it’s included.

It only goes for appointments added after you switch it on, never for your existing calendar, and it can’t be scheduled for later, such as that evening. Quiet hours skip it at night.

Clients can’t confirm the appointment by replying to it.

No: Etisia’s quiet hours are on by default, so no reminder goes out between 10 pm and 7 am in the appointment’s time zone.

A reminder that would land in that window is brought forward to about 8 pm. Example: a 1-hour reminder for a 7 am appointment goes at about 8 pm the evening before.

A booking message due at night is skipped, not postponed, and a change notice waits until 7 am. You can switch quiet hours off for any calendar.

Yes. When you write your own wording in Etisia, add the appointment time plus a time offset, and the text shows a window instead of a single time.

Example: “Our technician will arrive tomorrow between 9:00 AM and 11:00 AM.” A two-hour offset turns the 9:00 AM start into 11:00 AM. The preview shows the result before you save.

Move the appointment in Google Calendar and every reminder that hasn’t gone yet moves with it, with the new date and time in the text. There’s nothing to redo.

Example: you move a Thursday 2 pm visit to Monday 10 am, so the day-before reminder now goes on Sunday at about 10 am. If the move makes a pending reminder too late (say Friday’s visit moves to later today), Etisia sends one change notice about two minutes after your last edit.

A reminder that has already gone isn’t sent again for the new date, so tell the client about the move yourself or send a group message.

Yes, if you turn on the optional cancellation link. It’s off by default and available on every plan. Reminders and the booking message then include “Cancel at https://eti.is/aB3dE9.”

Your client opens the link, sees the appointment date, enters the mobile number the text went to and confirms. Etisia deletes the appointment from Google Calendar, stops its remaining reminders and emails you. The link only cancels: to move a visit, clients contact you.

If you delete an appointment yourself, its pending reminders stop.

In the US, texts come from Etisia’s US phone number. Every text starts with your business name, so clients know it’s you (“Glow Studio: Hello, …”), and ends with “Reply STOP to opt out.”

Sending from your own mobile number or under a custom sender name isn’t available in the US. To see exactly what clients get, use Add test appointment and check the text on your own phone.

Texts are one-way, with one exception: clients can reply STOP to opt out. Nobody reads other replies, there’s no inbox in Etisia, and a reply doesn’t confirm, cancel or move the appointment.

So clients can reach you, put your phone number in the message text. To let them cancel without calling, turn on the cancellation link.

Not in the US. Automatic review requests are only available to accounts in Etisia’s other countries, so US plans don’t include them.

Everything else works the same in the US: reminders, the booking message, the cancellation link and group messages.

Yes. Pick a day in one calendar to text everyone booked that day, for example about a closure or running late, and add other numbers by hand if you need to. Each client gets their own SMS, not a group chat.

Etisia skips clients who opted out and texts each number once. Every text uses SMS credits, and the send is refused if you don’t have enough for everyone. You can send offers to existing clients too, but texts aimed at new customers are blocked.

Etisia’s free trial gives you 21 days of Pro, with no credit card, including up to three calendars. Staff accounts and extra SMS packs need a paid plan.

You also earn up to 60 free SMS as you finish setup steps, such as connecting Google and sending your first reminder. It’s a one-time allowance, not monthly.

When the trial ends, nothing is charged and nothing renews: reminders stop until you choose a plan. Choose one earlier and you keep the free SMS you’ve earned.

Starter is $15 a month for one calendar and 100 SMS credits. Pro is $27 a month for three calendars and 250 credits. Team is $99 a month for unlimited calendars, staff accounts and 1,000 credits.

Paying yearly, Starter is $144 a year, about $12 a month, and yearly plans still get their credits every month. Prices exclude tax.

Every plan has up to three reminder times per calendar, your own wording, quiet hours, the cancellation link and group messages. Compare all plans.

In Etisia, one credit pays for one SMS of up to 160 characters. Longer texts are split into parts (segments) of one credit each, and emoji or some accented letters make each part shorter. The preview shows the count before you save.

US texts always include your business name and the STOP line, so with the cancellation link a reminder can take 2 credits.

100 credits cover about 100 appointments with one reminder, or about 50 with two. For around 120 texts a month, choose Pro, or add an extra 50-SMS pack to Starter when you need it.

Etisia stops sending and emails you, after warning you when credits run low. Your appointments stay in Google Calendar untouched.

On a paid plan, buy an extra pack of 50 SMS on the Subscription page, or switch on automatic top-up: it buys a pack when 10 or fewer credits are left, up to the 1–3 packs a month you allow.

Once credits are back, reminders still within their short catch-up window go out; older ones aren’t sent later. Plan credits reset each month and don’t roll over, while extra packs carry over.

Yes. The account owner changes plans in Etisia’s Subscription section; changes apply straight away and are prorated. You can’t move to a smaller plan while you use more calendars than it includes or have used more credits this month than it allows. Leaving Team removes staff accounts.

A cancellation takes effect at the end of the period you’ve paid for, and you can undo it until then.

You can request a refund within 14 days of a subscription start or renewal, no questions asked: email [email protected].

Look at the appointment in Google Calendar: Etisia adds “(SMS ready ✅)” to the title when a reminder is scheduled and “(SMS sent ✅)” once it has gone. You can switch these labels off.

Your SMS history in Etisia shows every text as Sent, Delivered, Not sent, Failed, Cancelled or Waiting, with a plain reason for anything not sent. Sent means handed to the mobile network; Delivered means the network reported delivery. Neither tells you whether your client read it or will come.

First, check that the appointment is in the Google account and calendar you connected. It’s the most common reason.

“(SMS missed ❌)” in the title means it was too late for your reminder time, usually after a short-notice booking, or the number isn’t a mobile. For short-notice bookings, add a closer reminder time or the booking message.

Other reasons: the client opted out, credits ran out, the calendar is paused or the Google connection expired (Etisia emails you to reconnect). SMS history shows the reason, and the help pages explain each one.

Yes, and your business is responsible for having it, not Etisia. During setup you tick a box to say you have your clients’ permission.

The simplest way: when a client books, tell them you’ll text a reminder, and keep reminders separate from promotions. In Etisia Contacts you can record how each client agreed, for example by phone booking, in person or from your own records, and add a note.

Every US text ends with “Reply STOP to opt out.”, so clients can reply STOP. If a client asks you in person or by phone, mark them as opted out in Etisia Contacts.

Clients marked as opted out get no further texts from your business. Opting out doesn’t cancel an appointment, so only change the booking if they ask.

Etisia reads only the calendars you set up and never changes times, descriptions or guests. You connect through Google’s own permission screen, which covers all your calendars, and Etisia never asks for your Google password.

It writes to your calendar only to add status labels, delete appointments clients cancel by link and add the setup test appointment. An AI service helps find client names in your events, and Etisia saves those clients (name and number) to your Contacts to send your texts.

Read our privacy policy. You can disconnect Google or delete your account at any time.

Yes. Use Etisia’s support chat on the website or in the app, email [email protected], or write to us on the contact page. The help pages walk through most setup questions step by step.

Tell us which calendar and appointment you’re checking and what you expected, and we can look at your setup with you. You never need to share your Google password.
