"I didn't get a notification" — why you shouldn't rely on app push to remind your guests

You know the scene. In the morning you check your calendar — the 10 o'clock appointment is there, everything's ready. It's ten past ten, and the chair is empty. You call the client, and she says: "Oh no, it completely slipped my mind — I didn't get any notification at all."

And the frustrating part is that, in a lot of cases, she's right. She really didn't get one. Not because your system is broken, but because you trusted the reminder to a channel the client quietly switched off — or never switched on in the first place.

In this article we'll walk through why an app's push notification isn't enough on its own, and why it's worth it for every salon to set up SMS reminders too — even if you're using an otherwise cutting-edge app.

Push notifications can be switched off silently — and often are

Push notifications are great: free, instant, and when they arrive, they work. The problem is with the "when they arrive" part.

For a client to receive a push notification at all, several conditions have to be true at the same time:

• They had to install the app. If your client booked with you from a simple link — the way most people do — then there's no app on their phone, so there's no push either.
• They had to allow notifications. On an iPhone this isn't automatic: the app asks separately, and a significant share of users simply decline. Industry measurements suggest that on iOS roughly half of people don't even enable push — the rate is better on Android, but it isn't 100% there either.
• The phone must not swallow it. Silent mode, "do not disturb," battery-saving background limits, a crowded notification bar that the client wipes away with one swipe in the morning — any of these is enough for your reminder to never reach their eyes.

So even in the best case, a push notification only reaches a narrowed audience, and even among them there's no guarantee they'll read it. And once a client opens their phone settings and turns notifications off, from then on they'll never get anything from you again — and you won't even know about it.

You can't turn off an SMS "by accident"

SMS is strong exactly where push is weak. It needs no app, no registration, no separate permission. It lands in the one inbox that practically everyone checks daily — and the phone number is already there, the one the client gave you when booking anyway.

The numbers back this up: while only a fraction of people open push notifications, almost everyone reads an SMS, usually within a few minutes. Not because SMS is "magic," but because there's no noise: you don't get fifty a day, so when one buzzes, the client looks.

In practice, this difference means the SMS reminder didn't just the client — it was actually in their hands.
