Klaviyo email diagnostics

Audit campaign-domain dependencies, authentication alignment, HTML payload risk and sender inventory around Klaviyo.

How to investigate Klaviyo evidence

Marketing delivery combines domain authentication with campaign markup, tracking and unsubscribe behavior. Mailybox keeps those dimensions visible together so a campaign is not declared ready based on DNS alone.

Signals worth checking

  • SPF and sender fingerprints
  • DKIM signing identity
  • DMARC alignment
  • HTML source size and tracking
  • Unsubscribe and campaign structure

Diagnostic path

  1. Map the sender surface before changing shared DNS.
  2. Inspect campaign HTML after the marketing platform has added production markup when possible.
  3. Use a delivered header to verify the actual signing identity.
  4. Evaluate tracking, accessibility and clipping pressure together with sender readiness.
