  • Budget planning: Estimate monthly appointment volume, calculate SMS needs, factor in no-show reduction savings - ROI typically positive.


Privacy and compliance

Key points

  • Be transparent: Clearly state SMS reminders will be sent, get implicit consent through booking form, provide opt-out mechanism.

  • Data protection: Store phone numbers securely, only use for appointment reminders, do not share with third parties, delete when no longer needed.

  • Compliance: GDPR (Europe) - get consent and allow opt-out, TCPA (USA) - respect do-not-call lists, local regulations and industry standards.
