Verified Mark Certificates (VMC) checklist for 2026

Short answer

A complete Verified Mark Certificates (VMC) checklist has 5 setup items and 3 things to audit against. Work through setup in order, then schedule a quarterly review.

Setup checklist#

  • ☐ Confirm your logo is a registered trademark in an accepted jurisdiction (USPTO, EUIPO, UKIPO, JPO, and others).
  • ☐ Prepare the exact trademarked artwork as SVG Tiny PS.
  • ☐ Complete organization validation with the CA, including notarized identity verification.
  • ☐ Receive the PEM certificate, host it over HTTPS, and reference it in the a= tag of your BIMI record.
  • ☐ Calendar the renewal; VMCs are valid for one year.

Audit checklist#

  • ☐ Confirm you are not: submitting a logo that differs from the registered mark, even slightly.
  • ☐ Confirm you are not: letting the certificate expire, which silently removes the logo.
  • ☐ Confirm you are not: assuming a pending trademark application qualifies; it must be registered.

Ongoing monitoring#

  • ☐ Weekly: review provider dashboards (Postmaster Tools, SNDS) and bounce logs
  • ☐ Monthly: re-run the setup verification after any vendor or DNS change
  • ☐ Quarterly: full audit against this checklist

Frequently asked questions#

How much does a VMC cost?

Roughly $1,000 to $1,500 per year per logo, depending on the CA.
