Email Sender Verification Seal

The signature image is only one part of verification

The sender domain must continue to publish a valid SPF record, the selected DKIM key and a DMARC policy. VerifySeal automatically rechecks these records according to the administrator schedule. For High Security messages, DKIM must cover the final Message-ID, VEM header and completed body.

  • SPF authorizes sending services
  • DKIM verifies the signed message domain
  • DMARC publishes the domain policy
Testing checklist

Confirm the installation is working

01

Visible

The complete 300 × 106 seal is visible in a received HTML message and is not cropped.

02

Clickable

The image opens the live VerifySeal sender certificate rather than an unlinked copied image.

03

Correct sender

The signature is assigned to the exact verified From address, not another identity or shared mailbox.

04

External test

A message received outside the organization retains the image, hyperlink and passing authentication results.

Platform notes
  • Email clients block JavaScript. Always use the Basic linked image and remember that some recipients also block remote images until they choose to display them.
