Why Mark Certificates?
Email Platforms
Get noticed in a crowded inbox
Mark Certificates — including Verified Mark Certificates (VMCs) and Certified Mark Certificates (CMCs) — let organisations display their official brand logo directly in customer inboxes.
The striking visual indicator serves as a major boost in brand recognition, email open rates and a reduction in phishing attacks. When your customers recognise your brand logo in their inboxes, they’ll immediately know that the email is being delivered from a reputable source.
They combine email authentication (DMARC) with brand validation, ensuring that your logo only appears on legitimate, secure messages.
In short: Mark Certificates give your emails instant recognition, credibility, and trust.
How Do Mark Certificates Work?
Mark Certificates are digital certificates that prove a company owns the rights to use its logo with email authentication. They are central to BIMI (Brand Indicators for Message Identification), which allows email clients to display a brand’s verified logo next to authenticated messages. This helps recipients quickly recognize legitimate emails while making phishing attempts easier to spot.
To obtain a Mark Certificate, an organization must undergo strict validation by a Certificate Authority (CA). The CA confirms that the logo is a registered trademark and that the organization has properly implemented DMARC with enforcement. Once issued, the certificate cryptographically binds the brand’s identity to its logo.
The result is both security and marketing value: customers gain visible assurance that an email is authentic, while brands benefit from improved trust and recognition in the inbox. Without a Mark Certificate, BIMI logos will not display, even if other authentication is in place.

Frequently Asked Questions
A Mark Certificate is a digital certificate that allows businesses to display their registered logo directly in the inbox next to outgoing emails. This visual branding increases recognition, builds trust, and helps reduce the risk of email spoofing or phishing attacks.
Verified Mark Certificate (VMC): Requires trademarked logos and organization verification. It’s the gold standard, ensuring your emails are authenticated and your brand is verified before logos are displayed.
Common Mark Certificate (CMC): A simpler option that allows you to display logos without requiring a registered trademark. It’s easier to obtain but provides a slightly lower level of assurance compared to VMC.
Mark Certificates improve your email deliverability, engagement, and brand recognition by making your logo visible right in the inbox. They also strengthen customer trust by confirming your emails are legitimate, reducing the chance that recipients mistake your messages for spam or phishing attempts.
DigiCert validates both your organization and your trademark. This includes confirming your business identity, domain ownership, and verifying that the logo you want to display is a legally registered trademark. Once validation is complete, your VMC is issued.
VMC: Yes, a registered trademark of your logo is required. This ensures only verified brand owners can display their logo.
CMC: No trademark is needed, making it easier for smaller businesses and startups to get started with branded emails.
CMC: Can often be issued quickly, sometimes within a day.
VMC: May take several days to a couple of weeks, depending on how fast you provide the required business and trademark documentation.
Mark Certificates work with email providers that support BIMI (Brand Indicators for Message Identification). Major providers like Gmail and Yahoo Mail already support it, with adoption continuing to grow across the industry.
After your certificate is issued, you’ll add a BIMI record (containing your logo information) to your domain’s DNS settings. Our team provides guidance to make setup simple, and DigiCert offers documentation to ensure a smooth process.
