Verified Mark Certificates

Verified Mark Certificates enable your logo to be displayed next to your organization's name in the sender information of your e-mails*. The receiver can then easily identify an e-mail author thanks to an upstream authentication process. It's the e-mail equivalent of a checkmark on social media.


* Compliant e-mail applications: yahoo!, Fastmail, Gmail, iOS 16 and Mac OS Ventura, laposte.net webmail.
E-mail applications pending compliancy: Comcast, Seznam.cz.

How does it work?

VMC is part of the BIMI (Brand Indicator for Message identification) initiative whose goal is to guarantee an enhanced email experience for both businesses and consumers. The main purpose being the quick identification of an e-mail sender and the certainty the e-mail is legitimate.


DMARC compatibility

BIMI standard requires the domain to be DMARC compliant. DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication, policy and reporting protocol that allows organizations to protect their domain against unauthorized use — including spoofing and phishing..

This process can take weeks or months, depending on the size of your organization. So it’s best to get started right away. Voir la documentation à ce sujet.

A registered trademark

The logo displayed on the e-mail client is not chosen at random. It must be a registered as a trademark with one of these offices:

A clear link must be established between the sender organisation and its logo. Whitout that registration, which will be checked during the audit process, the certificate won't be issued.

Government Marks

Government agencies do use registered trademarks. Instead, they use government marks authorized and protected by government agencies.

VMC now authorizes the use of government marks registered in the Official Journal or in one of the following administrative directories in addition to the directories listed above.

The SVG format

Your logo must be available in SVG Portable/Secure (SVG-P/S) format.

Warning: you won't be able to obtain this format via a vector application. You'll have to do it in several phases: first create your logo in SVG Tiny 1.2 format then use a text editor to modify it 'manualy' to get a BIMI compliant version. You can follow this documentation to create you logo.
