Reduce missed appointments with WhatsApp
Blastak operating procedure to reduce no-shows using confirmations, reminders, and post-visit follow-up.
Prerequisites
- Use the Solo, Pro, or Premium plan for post-visit messaging and the 2h reminder.
- Have at least one active service in Blastak.
- Have defined opening hours and business timezone.
- Have a WhatsApp contact number configured in settings.
Steps
- Confirmation mode is instant by default; focus on reminders and post-visit follow-up.
- Keep the 24h reminder enabled; from Solo onward, also keep the 2h reminder and post-visit follow-up enabled. Only enable 30m if your business justifies it.
- Make sure client messages always include the business name and the manage link.
- Track the confirmation rate and no-show share weekly in the dashboard.
Expected outcome
Clients confirm earlier, no-shows decrease, and the calendar stays reliable without constant manual follow-ups.
Troubleshooting
- If confirmations drop, check WhatsApp template status and fallback rates in the health metrics.
- If clients miss reminders, re-check the business timezone and the quality of phone numbers entered.
