Safeguard your brand and make email authenticity visible with Sectigo Mark Certificates
Email remains a critical digital communication channel for organizations seeking to connect and engage with customers. However, it is also a primary target for cybercriminals, with phishing attacks continuing to be the most prevalent form of cybercrime. The widespread use of email for business and personal interactions makes it an attractive avenue for attackers aiming to compromise sensitive information, impersonate trusted brands, or defraud recipients. Strengthening email authenticity in every inbox is essential for protecting both your brand reputation and your customers.
Sectigo Verified Mark Certificates (VMCs) and Common Mark Certificates (CMCs) help your email messages stand out by displaying your organization’s verified logo next to your emails in inboxes that support BIMI (Brand Indicators for Message Identification). BIMI is an email authentication standard that creates a structured method for linking authenticated emails with a brand’s validated visual identity.

Understanding Verified Mark Certificates (VMC) and Common Mark Certificates (CMC)
Verified Mark Certificates (VMC)
A Verified Mark Certificate is a digital certificate that confirms an organization owns the trademark rights to a specific logo. These high-trust certificates enable the Gmail blue checkmark, providing a clear signal of email authenticity. Companies use VMCs to help establish instant trust, improve email performance, and reduce the risk of impersonation attacks.
Common Mark Certificates (CMC)
Common Mark Certificates do not require registered trademarks, but do require a logo that’s been in public use for 12+ months. This is a faster, more affordable option for getting your logo displayed in email inboxes.
Manage Mark Certificates Seamlessly in SCM
Sectigo’s market-leading Certificate Lifecycle Management platform, Sectigo Certificate Manager (SCM) lets you request, issue, and manage VMCs and CMCs alongside other digital certificates. A simple wizard captures logos and validation information, while centralized lifecycle management ensures you:
- Track and renew all Mark Certificates in one place
- Consolidate multi-domain or multi-brand management
- Streamline issuance, validation, and deployment
- Maintain full operational visibility across your certificate ecosystem
