Appointment reminders

Missed appointments mean lost revenue. Send appointment reminders to reduce no-shows and backfill cancellations on the communication channels your customers prefer: email, SMS, WhatsApp, or voice. 

How to build appointment reminders with Twilio

Integrate the channels your customers use with your existing tech stack.

Step 1
Use Twilio’s developer-friendly platform and APIs to integrate with your appointment system database or customer relationship management system.

Step 2
Create workflows
Write code or use our low-code Studio editor to create reminder workflows via email, SMS, WhatsApp, or voice.

Step 3
Schedule and send notifications
Schedule reminders to go out at a set time—like one week, two days, or one hour before the appointment.

Step 4
Confirm, reschedule, or backfill
Collect responses by email, text, WhatsApp, or voice to confirm. Then reschedule or backfill any last-minute cancellations.

Step 5
Update system
Log confirmations or changes in the customer’s record and inform employees.
