Twilio integration enhancements
We've significantly improved how NeetoCal handles SMS delivery through Twilio, making it more reliable for businesses that send messages to clients across different regions.
Support for Twilio Messaging Service
Until now, NeetoCal supported only a single Twilio phone number as the sender. The integration flow has been redesigned to also support Twilio Messaging Services, allowing you to configure multiple sender numbers across regions.
Twilio automatically picks the right "From" number based on the recipient's location, so SMS delivery works smoothly even when your clients are spread across countries.
Region-aware SMS delivery
NeetoCal now uses the appropriate Twilio delivery API based on what you've configured — phone number or Messaging Service. This ensures messages are routed correctly and reduces failures caused by region-specific restrictions.
Email notifications for SMS delivery errors
You'll now receive email notifications for the two most common SMS delivery failures:
Error 21612 — when a message can't be delivered because the "From" number isn't supported in the recipient's region.
Error 21704 — when there's an issue with the configured Messaging Service.
This helps you catch and fix delivery issues faster, rather than finding out from clients that they never received a reminder.
