How can I manage Feedback-ID headers when using Amazon SES to send emails, especially with Gmail's upcoming sender requirements?

Summary

When using Amazon SES to send emails and adhering to Gmail's upcoming sender requirements, direct manipulation of the Feedback-ID header is not possible as SES automatically adds it. The focus should shift to ensuring proper email authentication (SPF, DKIM, DMARC), maintaining a positive sender reputation, actively monitoring and addressing feedback loop (FBL) reports, segmenting email lists based on engagement, and maintaining consistent sending volumes. While a second DKIM signature has been suggested, its impact on Feedback-ID management is unclear. Documentation from Amazon Web Services, ietf.org, and Google Postmaster Tools provides context on SES's automatic assignment, the tracking purpose of the header, and using Postmaster Tools for monitoring.

Key findings

  • SES Feedback-ID: Amazon SES automatically adds the Feedback-ID header, and you cannot override it.
  • Authentication: Proper SPF, DKIM, and DMARC configuration is essential for trust and compliance with Gmail's requirements.
  • Sender Reputation: Maintaining a positive sender reputation is critical, including sending relevant content and avoiding spam traps.
  • List Management: Engaged email lists, proper bounce handling, and double opt-in processes improve deliverability.
  • Engagement Metrics: Monitoring open rates, click-through rates, and unsubscribe rates helps identify deliverability issues.
  • FBL Monitoring: Actively monitoring Feedback Loop reports is crucial.

Key considerations

  • Impact Assessment: Understand the expected impact of the SES-assigned Feedback-ID.
  • Second DKIM: Consider a second DKIM signature to possibly separate data in Google Postmaster Tools, though its benefit to Feedback-ID management is uncertain.
  • Consistent Sending: Maintain consistent sending volumes.
  • Dedicated IP: Consider a dedicated IP (with careful warming) for greater reputation control.
  • Content Quality: Ensure content quality to prevent spam filters and promote engagement.

Managing Feedback-ID headers with Amazon SES and Gmail's new requirements involves understanding that SES automatically assigns these headers and overriding them is generally not possible. Focus should shift to ensuring proper email authentication (SPF, DKIM, DMARC), maintaining a positive sender reputation through engaged lists and consistent sending habits, and monitoring engagement metrics to comply with Gmail's updated standards.

Key opinions

  • SES Feedback-ID Override: Directly overriding the Feedback-ID header assigned by Amazon SES is typically not feasible.
  • Authentication Importance: Properly configured SPF, DKIM, and DMARC records are crucial for establishing trust with mailbox providers and complying with Gmail's requirements.
  • Sender Reputation: Maintaining a positive sender reputation is essential. This includes sending relevant content, avoiding spam traps, and promptly processing unsubscribes.
  • List Management: A clean and engaged email list is vital for deliverability. Regularly remove inactive subscribers, suppress hard bounces, and use a double opt-in process.
  • Engagement Metrics: Monitoring engagement metrics like open rates, click-through rates, and unsubscribe rates is critical for identifying and addressing deliverability issues.

Key considerations

  • FBL Monitoring: Although you can't control the Feedback-ID, monitor feedback loop (FBL) reports and address flagged issues promptly.
  • Dedicated IP: Consider using a dedicated IP address to build and maintain your own sender reputation, especially if you send a high volume of emails consistently. However, ensure the IP address is warmed up correctly.
  • Consistent Sending: Maintain a consistent sending volume rather than sporadic bursts to establish a predictable sender profile.
  • Content Quality: Ensure your email content is relevant and engaging to avoid spam filters and encourage positive engagement from recipients.
  • Testing: Test your emails before sending them to your entire list to identify potential issues with spam filters or rendering problems.
