Trademark Registration & Verified Mark Certificates for Gmail (BIMI)

Gmail Authenticated Brand Logos are part of a broader industry standard called BIMI – Brand Indicators for Message Identification. Under BIMI, participating email providers (including Gmail) can display a brand’s logo next to authenticated messages in the inbox. This gives recipients a clear visual indicator that the message is genuinely from your organization, not a spoofed or phishing email.

Gmail does not offer this as a separate “service” you apply for in an app store. Instead, Gmail reads public information about your domain—your authentication setup and your BIMI configuration—and decides whether to show your logo based on those signals and your sending reputation.

Why Trademark Registration Matters

BIMI is designed to prevent impostors from attaching a well-known logo to fraudulent emails. For Gmail and many other providers, that means your logo must be legally tied to you, typically through a registered trademark.

A registered trademark issued by the USPTO:

• Establishes your legal ownership of the logo
• Confirms that the logo is distinctive and associated with specific goods/services
• Forms the basis for the identity checks that must be completed before a Verified Mark Certificate is issued
• The federal trademark must have been actually used in the sale or advertising of the services.
• The federal trademark applicant must present certain facts in a verified written application to the USPTO, along with the appropriate filing fee.

For U.S. brands, this usually involves filing a trademark application with the United States Patent and Trademark Office (USPTO) for the logo you intend to use in email. Once the trademark is registered and in good standing, it can support your Verified Mark Certificate application.

What Is a Verified Mark Certificate (VMC)?

A Verified Mark Certificate (VMC) is a specialized digital certificate issued by a trusted certificate authority (CA). It is used in the BIMI ecosystem to prove that:

• Your logo is a registered trademark, and
• The organization sending the email is the same entity that owns that trademark.

In practical terms, a VMC is the bridge between:

• Your legal rights in the trademark (through the trademark office), and
• Your technical right to display the logo in supported inboxes (through BIMI and email authentication).

The VMC typically includes:

• The logo image that will appear in the inbox
• Details about the trademark registration (number, jurisdiction)
• Information identifying the organization and the issuing CA

For Gmail users, a VMC is what enables the trusted logo next to your email and, in eligible cases, the blue “verified” checkmark that signals a high level of authenticity to recipients.

How Do You Qualify for a VMC?

While each certificate authority has its own procedures, most follow a similar pattern. To qualify for a VMC, an organization generally must:

Own a registered trademark for the logo

• File and secure a registration with a recognized trademark office (for example, the USPTO in the United States).
• Ensure the registration is active and corresponds to the logo you intend to use.

Prove corporate identity and domain control

• The CA will verify your legal entity information (name, address, registration records).
• You must demonstrate control over the domain used in your From: address (e.g., yourbrand.com).

Have modern email authentication in place

• Your domain needs properly configured SPF, DKIM, and DMARC so that email providers can trust that messages really come from you and not from a third party.
• These checks are an essential foundation for BIMI, and CAs will generally confirm that your authentication posture is in line with BIMI expectations.

Once these conditions are met and the CA completes its review, it issues the VMC. That certificate is then used as part of your BIMI configuration so that services like Gmail can validate your logo.

Who Issues Verified Mark Certificates?

Verified Mark Certificates are issued by third-party certificate authorities—companies that specialize in validating digital identities and issuing certificates. In the BIMI context, they act as trusted intermediaries, confirming both your trademark rights and your organizational identity.

Well-known providers that issue or support VMCs (or related BIMI Mark Certificates) include, for example:

• DigiCert
• Entrust
• GlobalSign
• Other specialized certificate and email-security vendors that partner with these CAs

These providers typically coordinate directly with trademark offices such as the USPTO to verify that the trademark registration is valid and that it belongs to the organization requesting the certificate.

Because requirements and recognized trademark offices can vary by provider and jurisdiction, it’s wise to:

• Confirm which trademark offices a given CA recognizes
• Ensure your registration is with a supported office (e.g., USPTO for U.S. marks)
• Review the CA’s published guidelines before applying

How Gmail Uses VMCs and BIMI (High-Level View)

From a business and legal perspective, the flow looks like this:

• Your organization secures a trademark for its logo.
• You obtain a VMC from a participating certificate authority, which validates your trademark and organizational identity.
• Your technical team or email provider implements SPF, DKIM, and DMARC and then configures BIMI using your logo and the VMC.
• Gmail, when receiving messages from your domain, checks: (i) That the message passes SPF/DKIM, (ii) That DMARC is in place and aligned, and (iii) That a valid BIMI record and VMC support the logo

If those checks succeed and your overall sending reputation is sound, Gmail can display your authenticated brand logo (and, when applicable, the blue verification indicator) next to your messages. The result is a more visually trusted experience for your recipients.

Benefits for Brand Owners

For brand owners and trademark holders, investing in trademark registration + VMC + BIMI offers several advantages:

• Enhanced trust and credibility – A clearly displayed, verified logo reassures recipients that the message genuinely comes from your organization.
• Stronger brand recognition in the inbox – The logo appears right where users make open/delete decisions, reinforcing your brand identity and improving visibility.
• Better protection against impersonation – The combination of trademark rights, VMC validation, and strong email authentication makes it harder for attackers to pass themselves off as your brand.
• Support for email performance and reputation –  While results vary by sender, organizations that implement modern authentication and BIMI often see improvements in engagement and long-term sender reputation.
