Executive Summary
A leading news publication company faced a critical business disruption when their AWS Simple Email Service (SES) was suspended due to high bounce rates, preventing them from reaching over half a million customers. Our team at TechED Venture Limited successfully restored the SES service and implemented a comprehensive email deliverability solution that not only resolved the immediate crisis but also established a robust, fault-tolerant email infrastructure for sustained business operations.

Root Cause Analysis
- Email bounce rate of 15% - significantly exceeding AWS SES acceptable limits (typically <5%)
- Poor email list hygiene with numerous invalid email addresses
- Lack of monitoring and alerting for email deliverability metrics
