What caused your high bounce rate (AWS SES) ?

What caused your high bounce rate?

Our high bounce rate was primarily caused by two factors. First, our SMTP credentials were exposed, which led to unauthorized access and misuse of our AWS SES (Simple Email Service) account. Second, there was third-party abuse of SES, resulting in an increased bounce rate.

What changes have you made in your email-sending systems or processes?

To address these issues, we have implemented several changes in our email-sending systems and processes. Firstly, we have made broad security changes, including resetting and strengthening our SMTP credentials to prevent further unauthorized access. Secondly, we have configured a CloudWatch alarm to monitor and detect any suspicious activity related to our AWS SES usage. Additionally, we have enabled bounce and complaint notifications to promptly identify and address any delivery issues.

How do these changes ensure that the issue won't occur again in the future?

These changes are designed to enhance the security and monitoring of our email-sending systems. By resetting and strengthening our SMTP credentials, we have prevented unauthorized access and reduced the risk of similar incidents occurring in the future. The CloudWatch alarm helps us detect any suspicious activity, enabling us to respond swiftly and proactively. Enabling bounce and complaint notifications ensures that we receive immediate alerts and can take corrective actions to resolve any delivery issues promptly.

Overall, these measures not only prevent unauthorized access but also provide us with better visibility and control over our email delivery, minimizing the chances of similar high bounce rates in the future. We remain committed to maintaining a secure and reliable email-sending environment.
