Frequently Asked Questions (FAQ) for VMC certificates

VMC/BIMI certificates are supported by nearly 100% mail clients; it always depends on the client manufacturer (service).
The biggest supporter of displaying the logo in email is Google (co-author of BIMI); Gmail has supported VMC since its inception. VMC also operates in Yahoo and the certificates were recently adopted by Apple, too. On the other hand, only Microsoft does not support VMC (Outlook) and has not yet applied to accept it.

BIMI stands for Brand Indicators for Message Identification and is a specification that allows you to display a logo next to an authenticated email. It is an open specification that anyone can use without charge or restriction.

VMC (Verified Mark Certificate) is an acronym for a certificate that must be obtained to display your company's logo using BIMI technology.

BIMI can be set up by anyone for their own mail and for free, but no logo will ever appear in email clients as this requires VMC certification (the email service provider requires it, such as Google in Gmail). It is necessary to authenticate and regulate logo use in BIMI. Otherwise, anyone could set up any logo (such as a logo of a bank) and misuse it for phishing.

The VMC certificate is not installed in any way. After it is released, you will publish it (on the Internet) and set up a TXT record for the domain in question, which, among other things, contains the path to it. You can find more about deploying the VMC certificate in separate article.

The logo you want to display in BIMI for your messages must have a trademark. The trademark must be kept in one of the offices listed in the article What do I need to do to obtain a VMC certificate. You must have a trademark in place and DigiCert must find it in the database, otherwise the symbol/logo cannot be used.
