Amazon SES email diagnostics

Trace domain authorization, SPF dependencies, DKIM selectors and migration risks around Amazon SES sending.

How to investigate Amazon SES evidence

When SES is part of a sending path, the visible From domain, envelope identity, DKIM signing domain and public DNS can represent different layers. Mailybox focuses on those relationships rather than treating the provider name as a diagnosis.

Signals worth checking

  • SPF authorization references
  • DKIM selectors and delegation
  • Return-Path and visible From identity
  • DMARC alignment
  • Other sender services sharing the domain

Diagnostic path

  1. Verify a selector taken from a real message instead of guessing.
  2. Inspect alignment when the bounce names authentication despite SPF or DKIM passing individually.
  3. Map all sender services before modifying a shared SPF record.
  4. Simulate SPF changes before adding another include.

Questions this hub can answer

  • Is SES visible in this domain’s sender surface?
  • Does the DKIM selector resolve correctly?
  • Will adding SES exceed SPF dependency limits?
  • Does the authenticated identity align with the visible From domain?
