How it works
Send.
Confirm. Adjust.
Drag, wire, deploy. Each step is reversible — every save creates a versioned snapshot.
Configure the cadence
24h reminder, 1h reminder, day-of voice call — pick the combination per workflow. Templated body + channel.
Send via right channel
SMS for quick confirms. Voice for high-value or high-risk appointments. WhatsApp where it's the dominant channel.
Handle responses two-way
'Confirmed' → mark + skip subsequent reminders. 'Reschedule' → trigger booking flow. 'Cancel' → free the slot + offer to rebook later.
