The verification feature builds upon the existing logo verification system that was introduced nearly two years ago. It allows Gmail users to hover over the checkmark to confirm that the specified domain is owned by the associated company.
The blue checkmark feature is based on the Brand Indicators for Message Identification (BIMI) technology, which was launched in July 2021. BIMI enables users to display a validated company logo instead of a generic Gmail avatar.
Currently, the blue checkmark is only available to domain owners who have implemented BIMI and is not accessible to regular @gmail.com account holders. However, BIMI support extends to all versions of Gmail, including both Workspace and personal accounts, as long as they meet the necessary criteria.
