Today, we’re going to talk about something that may seem trivial, but believe me, it can change your life (professional, of course 😉): the SMS to confirm an appointment.

We’ve all been there: an overflowing calendar, a client who forgets their slot, and bam! an hour wasted. Frustrating, isn’t it? 😩 Well, it turns out that a well-thought-out notification can make all the difference. No more missed appointments that ruin your schedule and especially your revenue.

So, how do we go about writing THE perfect message? One that is both professional, friendly, and super effective? That’s what we’re going to see together. After this article, you will be the kings and queens of appointment confirmation via SMS! 👑

🤝 Why is SMS your best friend for confirming an appointment?

One might wonder: "Why bother with an SMS when an email will do the trick?". Excellent question! But the numbers speak for themselves. Hold on tight: the open rate for SMS reaches new heights, with an impressive score of 98%, compared to only 20% for emails. And that’s not all! The vast majority of SMS messages, about 95%, are read within three short minutes of being received. So, it’s safe to say that this is the most direct and instantaneous communication channel you can find.

Just imagine: you send a confirmation for an appointment and you are almost certain that your client will see it, and almost immediately. That’s pretty reassuring, isn’t it? No more crossing your fingers hoping your email doesn’t get lost in the spam abyss.

Personal anecdote:

I remember a hairdresser, let's call her Chloe, who was on the verge of a nervous breakdown due to missed appointments. She was wasting a lot of time and, of course, money. One day, she decided to try confirming appointments via SMS. At first, she was sceptical. And then, magic! ✨ Her no-show rate dropped dramatically. She told me it was like night and day. Her clients were thrilled with this handy little reminder, and she could finally organise her schedule calmly.

The benefits:

⏰ A phenomenal time saver:
No more endless reminder calls. A SMS to confirm an appointment can be sent in a few clicks, and you're done.
😎 A top-notch brand image:
Sending a confirmation SMS shows your clients that you are modern, organised, attentive, and that you care about them. It’s a small detail that makes a big difference and builds trust.
🧘‍♀️ Less stress, more business:
By reducing no-shows, you optimise your schedule, increase your efficiency, and ultimately improve the profitability of your business. It’s mathematical! In fact, some professionals estimate that this simple action can reduce the number of missed appointments by 75%, not bad, right?

You see, SMS marketing is not just a gimmick. It’s a powerful and incredibly effective tool for all professionals managing appointments, whether you're in beauty, health, real estate, or even automotive.

🧪 The secret ingredients of a perfect confirmation SMS

Now that you’re convinced of the usefulness of SMS to confirm an appointment, let’s get practical. How to write the ideal message? It’s a bit like a cooking recipe: you need the right ingredients, in the right proportions.

Clarity above all: keep it simple and direct

An SMS is short. Very short. Generally, you stick to 160 characters to ensure the message displays in full on all phones. So, no unnecessary chatter! Get straight to the point. Your client should understand the essentials at a glance.

Here are the essential details to include:

Your name or your business name:
This is fundamental, but it’s sometimes forgotten. The client needs to know who is writing to them.
The client's name:
Personalisation is key! A "Hello [First Name]" is much warmer and more engaging than a simple "Hello".
The date and time of the appointment:
This is the main information, so make sure it is clearly visible.
The location of the appointment (if necessary):
If you have multiple addresses or if it's a first appointment, please specify the location clearly.

Personalisation: the little touch that makes all the difference.

We've already talked about it, but I insist: personalise your messages! A professional SMS, for example an SMS that includes the client's name shows that you consider them as a person in their own right, not just a number in your database. It’s an excellent way to create a close and trusting relationship.

Type of personalisation	Example
Client's name	"Hello [First Name], your appointment is confirmed..."
Service details	"...for your transformation haircut on..."
Client's name	"...with Sophie on..."

The call to action: encourage a response.

To be 100% sure that your client has noted the appointment, it’s best to ask them to confirm their attendance. This is what we call a call to action.

A few simple and effective examples:

"Reply YES to confirm"
"If you are unable to attend, please let us know at [Phone Number]"
"To modify or cancel, click here: [Link]"

This simple phrase allows you to update your schedule in real time and avoid any unpleasant surprises.

🤖 The art of automation: how to schedule an SMS?

Sending confirmation SMS one by one is good. But when you have dozens of appointments per week, it can quickly become time-consuming. Fortunately, technology is here to save us! 🙏

Why automate? The superpowers of technology

Automation is simply the act of scheduling an SMS so that it sends itself, without you having to lift a finger (or almost). The benefits are enormous:

No more forgetfulness:
Once it's scheduled, you're all set. No more sticky notes on your screen reminding you to send confirmations.
Significant time savings:
The time you no longer spend sending SMS can be dedicated to your core business.
Consistent communication:
All your clients receive the same type of message, at the same time. It's professional and enhances your image.

How does it work? SMS platforms to the rescue

To automate your messages, the easiest way is to use an SMS platform. There are plenty available on the market, each with its own specifics. These platforms allow you to:

Create message templates:
You draft your SMS to confirm an appointment once and for all, and you can reuse it endlessly.
Import your contacts:
You can easily upload your client list to send bulk messages.
Schedule sending:
You choose the exact day and time your SMS should be sent. For example, you might decide to send a first confirmation right after the appointment is made, followed by a reminder 24 or 48 hours before.
Manage responses:
Some platforms offer the feature of 'automatic SMS response'. For instance, if a client replies 'YES', they can receive a thank you message.

Choosing a good SMS platform is crucial for a successful SMS marketing strategy. Take the time to compare offers and choose the one that best fits your needs and budget.

Did you know? On most Android smartphones, you can schedule an SMS directly from the 'Messages' app. It's a handy tip for occasional needs!

🕰️ The perfect timing: when to send your confirmation SMS?

We have the perfect message, we know how to automate it... but when should we send it? Timing is a crucial element of your SMS marketing strategy. A message sent at the wrong time risks being ignored or even bothering your client.

The right timing for maximum impact

There is no universal rule, as the ideal moment depends greatly on your industry and your clients. However, here are some points to consider:

The immediate confirmation:
Right after the appointment is made, send a first SMS to confirm that everything is in order. This immediately reassures the client and gives them a written record of their time slot.
The reminder 48 hours before:
A reminder two days before the appointment is an excellent practice. It gives the client time to organise and, if necessary, to reschedule the appointment without putting you in a difficult position.
The reminder on the day:
For those who are a bit forgetful (we all know a few!), a little reminder on the morning of the appointment can be a lifesaver.

Studies on consumer behaviour show that Tuesday and Thursday are often days when people are more receptive to marketing messages. Conversely, Monday morning (when everyone is busy) and Friday afternoon (when thoughts are already on the weekend) might be best avoided for non-urgent communications.

Absolutely avoid: timing blunders.

Sending a text too early in the morning or too late in the evening:
Respect your clients' sleep and privacy! 😴
Sending a message on Sunday evening:
This is generally not the best time to capture attention.
Harassing your clients:
One or two reminders is perfect. Five is starting to be too much!

The secret is to find the right balance. Don’t hesitate to test different time slots and analyse the results to see what works best for you.

Conclusion: The confirmation SMS, your new anti-stress ally!

And there you have it, we’ve covered everything! You now have all the tools to create the perfect SMS to confirm an appointment.

To summarise, here are the key points to remember:

SMS is a powerful marketing tool with unbeatable open and read rates.

To save time and increase efficiency, consider scheduling an SMS and using an SMS platform to automate your sends.
Timing is crucial: send your messages at the most opportune moments to maximise their impact.
