Case Study: Reassurance that Says “This Email Is from AmiAmi” at a Glance — Oh-ami Inc. Achieves Both Security and Branding with BIMI/VMC

Oh-ami Inc. operates "AmiAmi," a leading retailer of figures, plastic models, and hobby goods across online and brick-and-mortar stores. While sending large volumes of transactional emails—such as order confirmations and shipping updates—alongside marketing communications and contest notifications, the company faced growing concerns over sophisticated spoofing and phishing attacks. To alleviate customer hesitation to open messages and address customer feedback requesting clearer sender identification, upgrading email trustworthiness became a priority.

Collaborating across legal, IT, design, and customer support departments, the company addressed both technical and brand-asset requirements. By leveraging DMARC report analysis and consulting services, they safely and gradually strengthened DMARC policies across multiple high-volume domains.

Concurrently, Oh-ami implemented BIMI and VMC to display its official logo directly in recipient inboxes. This initiative reduced customer inquiries regarding email authenticity and provided the agility needed to accelerate policy enforcement during sudden spikes in spoofed email traffic, delivering substantial benefits in both customer reassurance and domain security.
