Can you integrate both SMS and WhatsApp in the same system?

Yes. Twilio's Messaging API supports omnichannel delivery. We build a unified notification service that routes messages to SMS, WhatsApp, or email based on user preferences and channel availability.

How do you handle SMS delivery failures?

We implement delivery status callbacks, automatic fallback to alternative channels, retry logic for transient failures, and alerting for persistent delivery issues.

Is Twilio Verify better than building OTP from scratch?

For most projects, yes. Twilio Verify handles rate limiting, fraud detection, and multi-channel delivery out of the box, saving 20-30 hours of custom development and ongoing maintenance.
