A Multi-Channel Strategy for OTP and Notifications: SMS + WhatsApp
Multi-channel does not mean sending every message through every channel. It means selecting a channel based on context and measuring the result.
An application can choose a primary channel based on message type, user preference or business rules. For critical messages, it can prepare a fallback when the primary channel fails or does not return the expected status within a defined time.
Avoid duplicate messages
Keep costs and customer experience under control by avoiding fallback too quickly. Record every sending attempt and use a correlation ID to connect one business event with multiple attempts.
Start simple and measure
Begin with a simple flow, measure delivery rate and delivery time, then adjust the rules using real data. API and webhook documentation provide the foundation for a maintainable implementation.
