Why a real message

Published DNS is not the campaign you send.

A domain checker cannot prove which DKIM signature arrived, whether unsubscribe headers were attached, what sender identity appears in the message, or which tracking the campaign carries.

  • Authentication and alignment on the delivered message
  • One-click and in-message unsubscribe evidence
  • Sender identity and postal-address indicators
  • Tracking and measurement risk
  • Applicability to your ESP, geographies and Gmail volume
