Recommendations by service type

Managing SMS credits and costs
Key points
• Each SMS sent consumes credits from SMS provider.
• Cost varies: Domestic SMS cheaper, international more expensive, bulk rates may be available.
• Optimize usage: Appropriate reminder timing (not too many), only send to confirmed appointments, consider email for some reminders.
• 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.
Troubleshooting
Common issues and solutions
| Issue | Check | Solution |
|---|---|---|
| SMS not being sent | SMS credits, provider configuration, phone number format, reminder configured | Verify SMS settings, check credit balance, test with sample appointment |
| Customer did not receive SMS | Wrong phone number, incorrect format, blocked by carrier, phone turned off | Verify number in record, check SMS delivery logs, resend manually, ask customer to check spam |
| SMS sent at wrong time | Reminder timing configuration, timezone settings, appointment time correct | Review reminder settings, verify timezone configuration, adjust timing if needed |
| Too many SMS reminders | Number of reminders configured | Reduce to maximum 1-2 reminders, ask for customer feedback |
Advanced configuration
Key points
• Custom SMS templates: Settings → Technical → SMS Templates → find "Calendar Reminder" → customize message content → use variables for dynamic content (date, time...) → test thoroughly.
