What data do deliverability consultants look for in inbox diagnostics?

Deliverability consultants examine multiple data sources:

  • Authentication audit: SPF, DKIM, DMARC configuration and alignment.
  • Reputation data: Postmaster tools, SNDS, third-party reputation services.
  • Engagement analysis: Open, click, complaint rates over time and by segment.
  • Content review: Spam trigger analysis, URL reputation, template evaluation.
  • List quality assessment: Bounce rates, hygiene practices, acquisition sources.
  • Sending patterns: Volume consistency, warming history, infrastructure setup.
  • Provider-specific investigation: Deep dive into problem providers.

A thorough diagnosis examines the ship, cargo, crew, and voyage history before prescribing repairs.
