WhatsApp No-Shows: How Reminders Reduce Them

01 · Glossary

What no-shows actually cost

The empty chair is the most expensive product in a service business.

• The slot's revenue is lost, not delayed
• Staff and materials were scheduled around it
• Late cancellations are almost as costly
• For merchants, no-show couriers and wasted dispatch slots compound

The reminder flow

Timing is the whole game.

• Send the first reminder 24–48 hours before
• Ask for a reply: confirm, reschedule, or cancel
• Confirmations lock the booking; reschedules fill the slot
• A same-day nudge catches the forgetful 10%

Cost and compliance

Reminders are cheap and compliant.

• Reminders about an existing appointment are utility messages
• US rate: $0.004 per conversation
• Customer replies inside 24 hours are free
• No opt-in needed for the specific appointment
