Case Study: Global AI Leader achieves DMARC Reject and stronger email security with Valimail

How an industry innovator in high-performance computing reaches DMARC enforcement

This global AI leader and premier supplier of specialized GPUs and chips — whose products power industries from gaming to automotive and mobile — needed to strengthen email security and scale safely across its operations. The company faced specific challenges with list servers and email authentication as it aimed to move to DMARC Reject without disrupting ongoing services.

Valimail provided a tailored, hands-on implementation: its Product Support team identified and resolved list-server issues, delivered dedicated onboarding, and integrated DMARC-as-a-service with minimal disruption. The result was a faster, lower-cost path to DMARC Reject, stronger email authentication, and a smooth transition that delivered clear price-to-value and ongoing customer confidence.
