Case Study: Global Aviation Company achieves 99.68% DMARC pass rate and blocks 85,000+ phishing emails with Valimail

Lifting Off with Email Authentication Streamlining Security at Scale in Global Aviation

One of Europe’s largest airlines—serving 240 destinations and carrying 169 million passengers in 2023 with a target of 225 million by 2026—faced growing email-security and deliverability issues as rapid expansion created a complex email ecosystem. Inherent flaws in email protocols led to domain abuse, blacklisting, poor deliverability and increased phishing risk, while budgetary constraints made large infrastructure changes difficult.

By partnering with Valimail’s DMARC-as-a-service and coordinating IT and marketing to enable BIMI, the airline enforced DMARC on 37 domains in under six months. The solution improved domain visibility, enhanced inbox experience, blocked more than 85,000 phishing attempts and delivered an average DMARC pass rate of 99.68%.
