Appointment reminders

Send Reminders That Actually Get Read.

Studies on SMS appointment reminders show a weighted average reduction in no-shows of about a third versus no reminder at all. TexMax sends them through a phone you already own.

Why it works

The Research Behind Why SMS Beats A Phone Call.

A systematic review of reminder studies found patient reminders improved attendance in 28 of 29 studies, with a weighted mean relative reduction in no-shows of 34% from baseline. Individual studies show the same pattern: one pediatric clinic trial cut no-shows from 38.1% to 23.5%, and a hospital study in India saw on-time arrival jump from 35.5% to 79.2% after adding SMS reminders. Text messaging has become the default method for exactly this reason: people read a text in seconds, and don't have to answer a call from an unknown number.

How it fits

Underneath The Booking System You Already Run.

Your booking software calls one API when it's time to remind someone. Nothing about how staff book appointments changes.

The API

One Template, Filled In Per Patient.

Save the reminder wording once with placeholders, then send it with each patient's real details. See the full API and gateway details.

Questions worth answering upfront.

Do I need special software to send appointment reminders by SMS?
No. Your booking system calls the TexMax API with the customer's number and the reminder text, and TexMax sends it through your paired Android phone. There's nothing new for staff to learn; the reminder just goes out automatically from your existing workflow.
Can customers reply to confirm or reschedule?
Yes. Replies are captured from the paired phone and delivered to your booking system through a webhook, so a customer texting back "YES" or "reschedule" can trigger whatever logic your application already handles for that.
Does TexMax replace my booking or scheduling software?
No. TexMax is the messaging layer underneath whatever you already use, whether that's a custom booking system, a CRM, or an off-the-shelf scheduling tool that can call a webhook or API. Nothing about your booking workflow needs to change.
How much does it cost to send appointment reminders through TexMax?
A flat €15 a month for one paired device, with no per-message fee, since reminders send through your own phone's existing SIM plan rather than a rented number billed per message.
