Path to Google’s Blue Verification Checkmark through Email Authentication

"Discover the steps to earn Google’s blue verification checkmark by setting up email authentication with DMARC, SPF, DKIM, and BIMI, enhancing email trust and security."

In response to the need for email authentication to protect companies from spoofing and solve deliverability issues, Google has taken a significant step forward by introducing verified blue checkmarks for senders in Gmail. With the new update, users will see a blue checkmark icon next to the names of senders, the company announced on Wednesday.

The blue verification checkmark applies to companies that have adopted the entire set of email authentication protocols, including BIMI (Brand Indicators for Message Identification).

BIMI (Brand Indicators for Message Identification) mandates senders adhere to a comprehensive set of email protocols. These include strong authentication through DMARC (Domain-based Message Authentication, Reporting, and Conformance) enforcement, which is attainable through SPF (Sender Policy Framework) alignment and DKIM (DomainKeys Identified Mail) alignment. Additionally, senders must obtain a VMC (Verified Mark Certificate) by providing evidence of trademark ownership, emphasizing the importance of email authentication in today’s world.

Email authentication is a crucial component for securing your brand’s reputation.

Our prediction for the future:

As email clients like Gmail take steps to increase email authentication adoption, it’s likely that we’ll see a shift toward making authentication a must-have for all senders. Email clients will flag domain names that fail to implement authentication and do not adhere to DMARC (Domain-based Message Authentication, Reporting, and Conformance) standards—mirroring the approach observed previously with not having SSL in place (non-HTTPS in browsers).
