BIMI stands for Brand Indicator for Message Identification. It’s a new approach that aims to prevent spoofing attempts but also increases the credibility of email senders. When fully implemented, hackers will have a very hard time trying to impersonate brands in emails, and maybe in a lot of other places too.
A BIMI record is a DNS TXT record indicating what a brand’s logo is. When properly certified and authenticated, brands will be able to display their logo next to each message in an inbox.

Learn about verified emails

When you see a blue checkmark next to emails in Gmail, it means that the sender has verified that they own the email address and brand logo.

To determine that an email is verified, Gmail uses the following:

BIMI (Brand Indicators for Message Identification): An open standard that allows email senders to use their brand logo in emails. BIMI helps give email recipients and email security systems increased confidence in the source of emails.
VMC (Verified Mark Certificate): A digital certificate issued by a certificate authority that verifies logo ownership.
DMARC (Domain-based Message Authentication, Reporting, and Conformance): A standard that helps email security systems filter and separate real messages from potentially spoofed ones.

Verified emails go through Gmail’s normal anti-abuse checks. If the emails pass, the sender’s verified brand logo is shown. To see which messages are validated through BIMI, DMARC, and VMC, look for the blue checkmark next to the sender’s name. The checkmark lets you know that the message is authenticated and authorized to show that logo.
