SMS Text Messages for Appointment Reminders
SMS text reminders are the single most effective no-show prevention tool. One 1-hour SMS can prevent 40% of no-shows.
Effectiveness comparison:
- No reminders: 20% no-show rate
- Email reminders: 16% no-show (20% reduction)
- SMS reminders: 12% no-show (40% reduction)
- Email + SMS: 10% no-show (50% reduction)
ROI: One prevented $100+ appointment = 2 years of SMS costs
Optimal timing:
- Email 24h before: Courtesy reminder, gives time to reschedule
- SMS 1h before: Urgency + confirmation, 60% response rate
- SMS 30m before (optional): Last-minute check
This combination reduces no-shows most.
SMS effectiveness (why it works):
- Urgency: SMS feels important
- Visibility: Not buried like email
- Timing: 1-hour window is perfect
- Interactivity: Clients can respond
- Confirmation: Response = commitment
