How Etisia works

Type your client’s name and phone number in a Google Calendar event. Etisia adds (SMS ready ✅) to the title and texts your client at the time you chose.

Made for businesses in Ireland: reminders go to your clients’ Irish mobile numbers, so a +44 number from Northern Ireland isn’t texted.

For every appointment

Setup in Etisia takes under a minute. After that, this is the whole routine. It happens in Google Calendar, on your computer or on your phone.

  1. Click a free slot

    Open Google Calendar and click the time of the appointment, the way you already do. Your appointments stay in your own calendar.

  2. Type the name and number in the title

    For example, Aoife Byrne 085 123 456•. The number alone is enough for the text to go out. Add the client’s first and last name too, and Etisia saves them as a contact in Etisia. A number in the description or location works as well.

  3. Save, and Etisia adds (SMS ready ✅)

    Etisia reads the new event and adds (SMS ready ✅) to the end of the title. That means it found the number and the reminder is scheduled. If it finds a client name but no number, the title says (SMS: no number) instead.

  4. Your client gets the text

    At the reminder time you chose, for example 1 day before, your client gets this:

    Hello, you have an appointment with us tomorrow, October 11, 2026 at 14:00. Best regards, Beauty Studio

    In Ireland, texts come from a sender name rather than a mobile number, so clients can’t text back. A client who needs to change something rings you, or uses the cancel link if you’ve switched it on.

    If you turn on the cancel link, the text also includes “Cancel at https://eti.is/ie1f4d.” Your client opens the link, enters their number and cancels. The appointment disappears from your calendar and you get an email.

  5. The title changes to (SMS sent ✅)

    Once the reminder has gone out, the title says (SMS sent ✅), so one look at your week shows who has been reminded. Next time Aoife Byrne books, typing “Aoife Byrne” is enough: Etisia finds the number in your Etisia contacts.

  6. After the appointment, your client gets a review request Pro

    Switch on review requests and Etisia sends one more text, with a link, after an appointment that got a reminder. By default it goes about 90 minutes after the scheduled end in the calendar, around 16:30 for this one, and not at night. It reads:

    Hey, thanks for visiting! Can you take 10 seconds to rate us? It would mean a lot: https://eti.is/r/K7QM2X

    By default Etisia asks the same client at most once every 90 days, and you can change that. Clients can’t reply to the text. On the review page they can opt out, and then they get no more texts from you, reminders included.

  7. Your client picks stars and taps the Google button

    The link opens a short page with stars. However many they pick, the same two buttons come next: “Leave a Google review” or private feedback to you. In Etisia you see who tapped the Google button; the review itself is written on Google.

What the brackets mean

Etisia writes a status in brackets at the end of each event title, so your calendar shows what happened without opening anything.

On track

Aoife Byrne (SMS ready ✅)
Etisia found a number. The reminder is scheduled.
Aoife Byrne (SMS sent ✅)
A reminder has gone out. (A text sent by “Immediately” changes the title only when that’s your only reminder time.)

Needs a look

Aoife Byrne (SMS: no number)
Etisia found a client name but no number, in the event or in your Etisia contacts. Add the number and the status changes to (SMS ready ✅).
Aoife Byrne (SMS missed ❌)
The reminder time and its allowed delay passed before the text could go out, for example because the appointment was added too late.
Aoife Byrne (SMS Error)
Etisia couldn’t send to this number, for example because it isn’t a valid phone number. Check the number in the event.

Not sent

Team meeting (no SMS)
Nothing to text: no number and no client name. Normal for a lunch break or a team meeting.
Aoife Byrne (SMS Opt-Out ⚠️)
This client opted out with the opt-out link Etisia can send, or you marked them as opted out in Etisia. No text goes out.

Some events get no status until you fix them: two numbers with nothing to show which one is the client’s, or a name and a number that belong to different contacts. Statuses appear for appointments in the next 90 days, in your account’s language, and you can turn them off.

When the text goes out

You choose up to three reminder times, on every plan. The default is 1 day before. For an appointment tomorrow at 14:00, that looks like this:

  1. Reminder time Today, 14:00
  2. Still sent if added by 20:00 As long as the appointment is at least 12 hours away
  3. Quiet hours 22:00 – 07:00
  4. Appointment Tomorrow, 14:00

Add an appointment after its reminder time and the text still goes out right away, as long as the allowed delay hasn’t run out. “1 day before” gets extra room: a booking added between 07:00 and 20:00, at least 12 hours before the appointment, still gets its text. After that, Etisia skips it, so nobody gets a reminder that comes too late. If no other reminder is left, the title shows (SMS missed ❌).

Quiet hours are on unless you turn them off: Etisia doesn’t text clients between 22:00 and 07:00 in the appointment’s time zone. A reminder that would land then is moved earlier, to about 20:00. An “Immediately” text that falls in quiet hours is skipped instead.

Each text goes out within about 15 minutes of its reminder time (within 5 minutes for “15 minutes before”).

Reminder times you can choose, and how late a text can still go out
Reminder time Allowed delay
1 month before 2 days
10 days before 1 day
1 week before 12 hours
2 days before 6 hours
1 day before default Added later? Still sent between 07:00 and 20:00 if the appointment is at least 12 hours away 3 hours
Smart Morning About 08:00 on the day, or about 20:00 the evening before for appointments before 10:00 1 hour
6 hours before 2 hours
2 hours before 1 hour
1 hour before 30 minutes
15 minutes before 10 minutes
Immediately About 2 minutes after you add a new appointment, outside quiet hours 30 minutes

Common questions

What exactly do I type in the event title?
The client’s phone number, for example 085 123 456•. Add their first and last name too (Aoife Byrne 085 123 456•) and Etisia saves them as a contact in Etisia. After that, the full name alone is enough. A first name on its own won’t find the contact.
When does Etisia send the reminder?
Up to three reminder times, anywhere from 1 month to 15 minutes before the appointment, or right after you add it. New accounts start with 1 day before. Unless you turn quiet hours off, a reminder due between 22:00 and 07:00 goes out earlier, at about 20:00.
What if I add an appointment at the last minute?
Add “Immediately” as one of your reminder times: every new appointment with a number then gets a text about 2 minutes after you save it, outside quiet hours. Without it, a booking added after its reminder time still gets the text while the allowed delay lasts; with “1 day before”, also until 20:00 for appointments at least 12 hours away. Otherwise the title shows (SMS missed ❌).
Do I have to do anything in Etisia for each appointment?
No. You add appointments in Google Calendar as usual. Etisia reads them and sends the reminders.
What does the text say?
The date and time of the appointment and your business name. It never includes the client’s name. You pick the wording during setup, and you can turn on the cancel link.
Can clients answer the text?
No. Etisia has no inbox for answers. A client who needs to change or cancel calls you, or uses the cancel link if you turn it on.
Does Etisia change my appointments?
It adds the status after your own title and doesn’t create or move appointments. If it finds a client name but can’t use the number at the end of the title, it removes that number when it writes (SMS: no number). The one other change is the optional cancel link: a cancellation through it deletes the event, and Etisia sends you an email.
Do my clients need an app?
No. They get a normal text message on their phone.
Can I change the reminder times or the text later?
Yes. Everything you chose during setup can be changed in your Etisia dashboard, and you can turn reminders off at any time.
What does Etisia cost in Ireland?
Starter costs €20/mo billed yearly (tax excl) after the 21-day free trial, and no card is needed to start. See prices for Ireland
