# How do you use SMS for appointment reminders?

> SMS appointment reminders cut no-shows by delivering a timely, high-open-rate reminder with the date, time and location, plus a reply-to-confirm or reply-to-reschedule option using two-way SMS. Because SMS needs no app and is read within minutes, it reaches patients and customers that email and app notifications miss — which is why clinics, healthcare providers, salons and service businesses rely on it. See /products/two-way-sms.

## Why SMS works for reminders

SMS lands on every phone with no app or login, and industry studies consistently report SMS open rates far above email, with most messages read within minutes. That immediacy is exactly what a time-bound reminder needs.

## Make it two-way

Let recipients reply C to confirm or R to reschedule; route the responses back into your booking system with two-way SMS and webhooks. A confirm/reschedule loop reduces both no-shows and the staff time spent on reminder calls. See /products/two-way-sms and /answers/what-is-mo-vs-mt.

## Timing and cadence

A common pattern is one reminder 24–48 hours ahead (enough time to rebook the slot) and an optional same-day nudge. Respect quiet hours and the recipient's timezone.

## Consent and healthcare compliance

Collect opt-in at booking, keep reminders strictly transactional, and in healthcare avoid clinical detail in the message body. See /answers/hipaa-for-messaging and /answers/gdpr-for-messaging.
