We’ve improved delivery tracking for emails sent through the AWS SES integration. Courier now captures and surfaces more detailed delivery events from SES, giving you better insight into what’s happening after messages are sent. This makes it easier to monitor email performance, diagnose delivery issues, and confidently rely on SES as part of your notification stack.
