BIMI Certificate Authority

Understanding BIMI Certificate Authorities

Brand Indicators for Message Identification (BIMI) is a powerful email authentication standard that allows businesses to display their brand logo in email inboxes, enhancing trust and recognition. A critical component of implementing BIMI is obtaining a certificate from a BIMI Certificate Authority, also known as a Mark Verifying Authority (MVA). At MxToolbox, we help you navigate this process to ensure your emails stand out as authentic and trustworthy.

What is a BIMI Certificate Authority?

A BIMI Certificate Authority, or Mark Verifying Authority (MVA), is a trusted third-party organization that verifies a domain’s ownership of a brand logo used in BIMI. The MVA issues a Verified Mark Certificate (VMC) or, in some cases, a Common Mark Certificate (CMC), which serves as proof that the domain owner has the legal rights to use the specified logo. This certificate is essential for ensuring that your brand’s logo is displayed securely in email clients like Gmail, Yahoo!, and Apple Mail.

Why is a BIMI Certificate Authority Important?

The role of a BIMI Certificate Authority is to prevent fraudulent use of brand logos in email communications. Without proper verification, spammers could misuse a company’s logo on fake domains to deceive recipients. By requiring a VMC or CMC, inbox providers ensure that only legitimate businesses can display their logos, protecting both the brand and email recipients from phishing and spoofing attacks.

- Enhanced Brand Trust: A VMC or CMC certifies that your logo is authentic, reassuring recipients that your emails are legitimate.
- Improved Email Deliverability: BIMI requires strict DMARC compliance, which, when paired with a verified certificate, boosts your sender reputation.
- Visual Brand Recognition: Displaying your logo in the inbox increases open rates and strengthens brand visibility.

How Does a BIMI Certificate Authority Work?

A BIMI Certificate Authority, such as DigiCert or Entrust, follows a rigorous vetting process similar to issuing Extended Validation Certificates (EVCs) for websites. The process includes:

1. Domain Verification: Confirming that you own the domain associated with the BIMI record.
2. Logo Ownership Validation: Verifying that you hold the rights to the logo, often requiring a registered trademark for a VMC.
3. Certificate Issuance: Issuing a VMC or CMC, which is then referenced in the “a” tag of your BIMI DNS record.
4. Integration with BIMI: Once the certificate is added to your BIMI record, inbox providers validate it alongside SPF, DKIM, and DMARC checks to display your logo.

Verified Mark Certificate (VMC) vs. Common Mark Certificate (CMC)

There are two types of certificates issued by BIMI Certificate Authorities:

- Verified Mark Certificate (VMC): Requires a registered trademark and is the standard for maximum trust. It is more expensive (typically $1000–$1500 per year per domain) but is widely supported by major inbox providers like Gmail.
- Common Mark Certificate (CMC): A newer, more accessible option that does not require a trademark, making it suitable for small and medium businesses. Google recently announced support for CMCs, broadening BIMI adoption.

While CMCs lower the barrier to entry, their pricing and availability are still being defined by vendors, so stay tuned for updates.
