DigiCert Common Mark Certificate

What is a Common Mark Certificate (CMC)?

A Common Mark Certificate (CMC) displays logos that your organization regularly uses but has not officially registered as trademarks. It allows logos to be shown in email clients like Gmail, enhancing your organization's visibility.

Why implement CMC?

1. Easier access: CMC is easier to obtain for most customers who do not have a registered trademark.
2. Show more logos: It allows for displaying multiple logos beyond those with trademarks.
3. Increased visibility: CMC helps improve brand recognition, making it easier for customers to identify your organization in their inbox.
4. Enhanced trust: Displaying a familiar logo can increase trust in your email communications.

What is required to implement CMC?

1. An active DMARC policy with 100% reject or quarantine.
2. A square (round) SVG-P/S vector file of the logo.
3. Documentation from archive.org showing the logo has been used for at least a year.
4. A CMC DNS record pointing to the logo.
