Common Mark Certificates (CMCs) allow companies to render their brand logo next to the “sender” field in email clients—visible even before the message is opened.

DigiCert’s Common Mark Certificate supports

• Prior Use
• Modified Registered Trademark

Marketers will be interested in the potential for:

• Increased open rates
• Improved brand recognition

Implementing all the requirements for CMCs also signals that your company is DMARC compliant, showing that you are protecting your domain against unauthorized use – including spoofing and phishing.

DigiCert can host your logo and certificate files. We will:

• Automatically push the latest version of the files to our hosted server, so you don’t need to make any changes when you renew or reissue your certificate.
• Match the PEM file (certificate) byte-for-byte to your logo SVG file.
• Provide the file locations and detail instructions on how to set up DNS record to point to the hosted files.
• You don’t need to find a place to host the logo and certificate files.
• You don’t need to involve other IT teams.
