Introduction

Meeting Verified Mark Certificate (VMC) requirements takes more than just signing up — it involves technical DNS preparation, trademark validation, and strict logo formatting before your verified logo can appear in customer inboxes. Specifically, businesses must satisfy standards set by certificate authorities (CAs) like DigiCert, covering everything from authentication records to SVG logo specs.

To ensure a smooth approval process, therefore, businesses should prepare their domain settings, logo assets, and authentication records well in advance. This article breaks down each key requirement so you know exactly what to expect before applying.

1. Domain Authentication Requirements

First and foremost, your domain must have proper email authentication protocols correctly configured in DNS:

• SPF (Sender Policy Framework):
  Specifies which servers are authorized to send email for your domain.

• DKIM (DomainKeys Identified Mail):
  Digitally signs your emails to confirm authenticity.

• DMARC (Domain-based Message Authentication, Reporting & Conformance):
  Must be set to either:

  • p=quarantine

  • p=reject
    ➝ A “none” policy does not qualify for VMC.

✅ All three records must be valid and correctly published in your DNS before you proceed.

2. BIMI DNS Record

Once your authentication records are in place, the next step is publishing a BIMI record to connect your logo to your domain. Without this record, even a correctly formatted logo will not display in supported inboxes.

Here is an example BIMI record:

• l= points to your logo file (SVG Tiny PS 1.2).

• a= points to your VMC certificate.

✅ As a result, both values must be publicly accessible and correctly formatted for the record to validate successfully.

3. Logo Requirements

In addition to DNS setup, your brand logo must meet strict technical guidelines before it qualifies for a Verified Mark Certificate. Specifically:

• File format: SVG Tiny PS 1.2 — other formats will be automatically rejected.

• Trademarked: The logo must already be registered as a trademark with an official authority.

• Design:

  • Square aspect ratio recommended

  • Transparent or solid background only

  • Avoid gradients or overly complex patterns because they may not render properly across all supported inbox providers.

✅ Tip: Logos that are not trademarked or not in the correct SVG format will be rejected immediately — so it’s worth verifying both before submission.

4. Trademark Requirement

That said, the trademark requirement is where many applicants get caught off guard. A VMC requires verified proof that your logo is a registered trademark — not just pending registration.

• Accepted documents include official trademark certificates from recognized national or international authorities.

• Furthermore, the logo on your trademark certificate must exactly match the logo you submit for VMC — even minor differences can cause rejection.

• Pending trademarks are generally not accepted, so plan your timeline accordingly.

Because of this requirement, only legitimate brand owners can display verified logos in customer inboxes — which is precisely what makes BIMI valuable as a trust signal.

5. Certificate Authority Validation: The Final VMC Requirement

Finally, when you submit your VMC application, DigiCert actively validates three key things:

• Your organization details through legal entity verification

• Your domain ownership via DNS checks

• Your trademarked logo against your submitted trademark certificate

According to DigiCert’s official VMC documentation, this thorough process prevents fraud and ensures that only verified businesses receive certificates. Consequently, applicants who skip any of the earlier steps will face delays or outright rejection at this stage.
