Appointment reminder
An appointment reminder is an automatically sent message that reminds customers of their booked appointment in good time. Sent via WhatsApp, it achieves an open rate of over 90% – and measurably reduces no-shows.
hellomateo fully automates appointment reminders: Time, content, and follow-up messages are configured once and then sent without any manual effort.

A appointment reminder via WhatsApp is one of the most effective measures for reducing appointment cancellations. Studies show that automatic reminders can reduce the no-show rate by up to 50% – a huge economic advantage, especially for deadline-driven industries.
When should the appointment reminder be sent?
The optimal strategy involves a multi-stage reminder: 24-48 hours before the appointment and again 1-2 hours before. hellomateo allows you to configure multiple reminder levels with individual texts and time intervals.
