What are the limitations of Amazon SES regarding Microsoft SNDS access and is there a workaround?

Summary

Amazon SES's primary limitation is the lack of direct access to Microsoft's SNDS. While frustrating, this is due to Amazon's policy to prevent data leaks. To compensate, SES provides SNDS-related data through CloudWatch metrics and encourages using alternative methods to maintain deliverability. These include closely monitoring SES metrics (bounce/complaint rates), setting up SNS notifications, implementing feedback loops with ISPs, leveraging third-party tools, and ensuring proper SPF, DKIM, and DMARC setup. Ultimately, a proactive approach to reputation management and deliverability is crucial.

Key findings

  • No Direct SNDS Access: Amazon SES does not provide direct access to Microsoft SNDS due to its security policy.
  • CloudWatch Data: Amazon SES provides SNDS-related data, such as complaint and bounce rates, through CloudWatch metrics.
  • Alternative Monitoring: Monitoring SES reputation metrics, setting up SNS notifications, and using third-party tools are viable alternatives to direct SNDS access.
  • Feedback Loops: Setting up feedback loops (FBLs) with major ISPs, including Microsoft, helps in identifying and removing problematic recipients.
  • Sender Authentication: Proper configuration of SPF, DKIM, and DMARC is essential for improving email deliverability.
  • Reputation Focus: Maintaining a clean sending reputation is critical for deliverability to Microsoft domains.

Key considerations

  • Monitor SES Metrics: Regularly monitor bounce and complaint rates within the SES dashboard and CloudWatch.
  • Implement FBLs: Establish feedback loops with major ISPs to proactively address complaints.
  • Use Third-Party Tools: Consider using third-party tools for more detailed deliverability reporting and analysis.
  • Authenticate Email: Ensure SPF, DKIM, and DMARC are correctly configured for your sending domain.
  • Reputation Management: Actively manage sender reputation by promptly addressing complaints and removing problematic recipients. Take reputation seriously.
  • Adapt to Policy: Accept that Amazon's policy regarding SNDS is unlikely to change, and focus on utilizing available alternatives.
