What are Verified Mark Certificates?

Verified Mark Certificates (VMCs) are digital certificates that enable organizations to display their registered trademark logo in the avatar slot alongside outgoing emails.* 

Our VMCs adhere to the specifications of BIMI (Brand Indicators for Message Identification) and help your emails stand out and get noticed in a crowded inbox while protecting them against fraud through DMARC’s anti-spoofing technology. 

It’s simply the smartest way to send emails. 

* Displays on Gmail and other email service providers that support BIMI.
