It seems that blue verification checks are currently in style. To make Gmail safer and more secure, Google has released a new version. This upgrade will indicate verified senders in Gmail by adding a “blue checkmark” after the sender’s name.
Gmail will display a Blue Checkmark for verified senders
In 2020, Google made the first version of Brand Indicators for Message Identification (BIMI) support for Gmail available. With their official logo in place of the sender avatar, organisations and vendors can use BIMI’s core functionality to assert ownership of their respective businesses. This action was taken to combat spam emails and brand identity theft. In 2021, BIMI had another update that added even more robust security features. However, it appears that BIMI was unable to fully accomplish its goals.

Google is now ensuring that you are aware of the legitimacy of the communications in your inbox, taking BIMI one step further. In this new step, a blue checkmark will be added to Gmail after the sender’s name. This proves that the aforementioned sender is the true owner of the email in your inbox and that they have authenticated their identity with Google via BIMI.
Availability
As of right now, every verified sender will display a blue checkmark next to their official emblem whenever you receive a new email from a company or organisation. A floating pop-up letting you know that the sender owns the domain and the logo will show up if you linger over the checkmark.
For the vast majority of end users, you will soon be able to see this update. All users of personal Google accounts, Workspace subscribers, and legacy G Suite Basic and Business clients will have access to this new feature. The full rollout of this new blue checkmark update in Gmail has now begun.
To understand how to validate your company with BIMI, you can visit the official Google Workspace Admin blog if you are an admin.
Regarding the announcement, Google said,
Strong email authentication helps users and email security systems identify and stop spam, and also enables senders to leverage their brand trust. This increases confidence in email sources and gives readers an immersive experience, creating a better email ecosystem for everyone.
