Automatic appointment SMS reminder The SMS sends itself. You focus on your work.
A client who forgets means an empty slot and an evening spent filling it. With Calendrio, every confirmed appointment triggers a reminder by email and, if you wish, by SMS, at the time you chose.

How do I send an SMS reminder before every appointment?
You need a calendar that knows the time of each appointment and the client's number, and sends the SMS for you. In Calendrio, you set the reminder timing once (2 days, the day before, 2 hours or 1 hour before); after that, every confirmed appointment gets its SMS, whether it was booked online or added by you. Reminder SMS are included every month in the Pro and Team plans, and email takes over if an SMS can't be sent.
What your client receives
Example of a reminder SMS
Reminder: your appt. with Atelier Lumière tomorrow at 2:30pm. Cancel or reschedule: calendrio.fr/cancel.php?token=…
Special characters are removed so the message fits in a single SMS.
- Short and clear: your business name, the day and the time. Nothing promotional.
- A link to let you know: the client can cancel online, according to your cancellation rules, and the time slot is freed up for someone else.
- An email as well: with the address, the video call link if there is one and a button to add the appointment to their calendar.
- Never without a reminder: if there is no phone number or the balance is empty, the email is sent instead.

Set up your reminders in 3 steps
- 1. Open Settings, then Business, and scroll down to the “Your clients' reminders” block.
- 2. Choose when the email goes out (the day before, 2 days, 2 hours or 1 hour before), then, under “By SMS, in addition”, when the SMS goes out.
- 3. Save. For a specific appointment, you can change its reminders in “Add appointment”: up to 3, from 15 minutes to 2 days before, or the same morning.
Good to know: an appointment awaiting your approval only gets its reminder once it is confirmed. Clients can choose when they receive their email reminder when booking, or later from their account.
When should the SMS be sent?
The day before suits most businesses: the client still has time to let you know, and you have time to offer the slot again. For a short session or one booked the same day, 1 or 2 hours before is enough. For a long service booked well in advance, combine an email 2 days before and an SMS the day before.

Frequently asked questions about SMS reminders
How do I send appointment reminder SMS automatically?
With Calendrio, open Settings, then Business, and the “Your clients' reminders” block. Under “By SMS, in addition”, choose the timing: 2 days before, the day before, 2 hours or 1 hour before. The SMS is then sent automatically for every confirmed appointment where the client left a mobile number. This option is included in the paid plans and during the trial.
How much does an appointment reminder SMS cost?
Reminder SMS are included every month: 50 with the Pro plan (€39 excl. VAT per month), 200 with the Team plan (€79 excl. VAT per month), 10 during the free trial. They don't roll over from one month to the next. Beyond that, each SMS costs €0.10 excl. VAT, taken from your account balance.
What happens if my SMS balance is empty?
The reminder is sent by email instead. The same applies if the client hasn't given a mobile number: they still get a reminder, by email.
What does the reminder SMS sent to the client contain?
A short message, written to fit in a single SMS: your business name, the day and time of the appointment, and a link to cancel online. The text is the same for all appointments; for a personalized message, you can write an SMS yourself from the Calendar & CRM.
Are SMS reminders available on the free plan?
No. On the free plan, your clients receive an email reminder the day before their appointment. SMS reminders, choosing the timing and multiple reminders are included in the paid plans and during the 1-month trial, no credit card required.
Can I send several reminders for the same appointment?
Yes, on the paid plans and during the trial. In the “Add appointment” window, under “Remind the client”, you can set up to 3 reminders, by email or SMS, from 15 minutes to 2 days before, or the same morning. For example: an email 2 days before, then an SMS 2 hours before.
Fewer forgotten appointments, without a second thought.
