attendance with notifications

What research says about text reminders and no-shows.
Text reminders have evidence behind them in healthcare settings. That does not guarantee the same outcome in every service business, but it gives a useful reason to test a consistent reminder process.

What a service business can learn from this
The safest takeaway is operational: reminders can be worth testing when missed appointments are a recurring problem. Measure your own baseline and compare it with your results after introducing a consistent process.
Confirm the booking
Make the appointment date, time and rescheduling path clear when the booking is created.
Use a consistent reminder point
Choose a reminder schedule that fits your customers instead of relying on staff memory.
Track the result
Compare booked appointments, cancellations and no-shows before and after the reminder routine.
Source and methodology
Original source: BMJ Open — Using digital notifications to improve attendance in clinic. The 2016 systematic review included 26 articles; 21 studies were included in its primary meta-analysis comparing electronic text notifications with no notifications.
This evidence comes from healthcare settings and should not be treated as direct proof of the same effect in salons, trades or other service businesses. VARELIOX uses it to support testing a reminder process, not to promise a particular reduction in no-shows.
