How to improve email sender reputation with Amazon SES Email Validation
Amazon SES Email Validation helps protect sender reputation by shifting from reactive to proactive bounce management Amazon SES Email Validation enables organizations to protect sender reputation by detecting problematic email addresses before they cause bounces. The feature offers two approaches: the Email Validation API for real-time checks during registration and Auto Validation for automatic pre-send verification. High bounce rates (over 5%) trigger warnings from mailbox providers like Gmail and Outlook, while rates exceeding 10% can result in throttling or blocking. The solution provides confidence verdicts (HIGH, MEDIUM, LOW) to help organizations decide which addresses to accept, integrating with existing workflows and CloudWatch metrics for ongoing list health monitoring.
