Benefits
Why whatsapp reminders with Twilio and SchedulingKit makes a difference.
Higher engagement than SMS
WhatsApp messages have a 99% open rate and 40% response rate. Clients interact with reminders rather than ignoring them.
Interactive confirm/reschedule buttons
Clients tap 'Confirm' or 'Reschedule' directly in WhatsApp. No phone calls, no logging into a portal.
Rich media support
Attach location pins, preparation documents, or images to reminder messages. Send a map pin so clients know exactly where to go.

WhatsApp Reminders in Practice
A real-world look at how Twilio whatsapp reminders works with SchedulingKit.
A travel agency with 15 agents books 300 client consultations per month, with 60% of clients located internationally. Email reminders had a 22% open rate and SMS delivery was unreliable to numbers in Southeast Asia and South America. They switch to WhatsApp reminders via Twilio.
When a client in Jakarta books a trip planning session for Friday at 9 AM EST, they receive a WhatsApp reminder 48 hours before: the message includes the appointment date and time converted to their local timezone (Friday 8 PM WIB), the agent's name and photo, a Google Maps link to the virtual meeting room, and two buttons: "Confirm" and "Need to Reschedule." The 24-hour reminder adds a preparation checklist: passport details, travel dates, and budget range.
After switching to WhatsApp, the agency tracks engagement across channels. WhatsApp reminders achieve a 97% delivery rate (vs. 78% for international SMS) and a 52% confirmation button tap rate. No-show rates for international clients drop from 28% to 9%, recovering an estimated 57 appointments per month that would have been no-shows.
The agency also uses WhatsApp's document sharing feature to attach a pre-consultation questionnaire as a PDF. Clients who complete the questionnaire before the call convert to booked trips at 45%, compared to 28% for unprepared clients. The WhatsApp delivery of the questionnaire increased pre-call completion rates from 30% to 71%.
