Messaging & Targeting Blog



This article provides a comprehensive guide to building resilient SMS delivery using AWS End User Messaging, focusing on strategies to ensure reliable message transmission across different potential points of failure.

  • SMS delivery is complex, with multiple potential disruption points including carrier availability, network issues, and device conditions
  • Three levels of SMS resiliency are recommended:
    • Originator-level: Using multiple origination numbers per country
    • Account-level: Having secondary accounts with shared resources
    • Region-level: Configuring originators in multiple AWS Regions
  • Best practices include:
  • Using phone pools with multiple origination identities
  • Implementing dedicated originators for each country
  • Centralizing delivery receipt data
  • Utilizing message feedback features

The goal is to create a robust messaging architecture that can withstand SMS delivery challenges while minimizing disruption to communications.
