Setting up SMS reminders
SMS beats email for appointment reminders — 98% open rate vs. 20%. Here's how we configure the two-step sequence that actually moves no-show rates.
Go to Settings → Notifications → Reminders. Enable both the 24-hour and 2-hour SMS templates. The 24-hour message should include a one-tap reschedule link — that single addition cut no-shows another 9% in our A/B tests.
SMS costs vary by country; most EU sends run €0.04–0.08 per message. A no-show costs you €70–200 in lost revenue. The math is not close.
Keep messages under 160 characters when possible so they arrive as a single segment. Long URLs get shortened automatically.
