ICYMI: Disinformation and Malicious Email Report: Why DMARC Remains Pivotal

In case you missed it, I recently co-hosted a webinar diving into the findings of Valimail's 2025 Disinformation and Malicious Email Report, alongside Warren Duff from Valimail and security expert Chris Cravens. We unpacked the evolving threat landscape around phishing, spoofing, and domain impersonation—especially in light of AI-driven attack vectors—and why DMARC remains a very important line of defense against email impersonation for organizations of all sizes.

With updated sender requirements now in place from Microsoft (joining Google and Yahoo), there's never been a more urgent time for bulk senders to get serious about email authentication.

We also touched on DMARC adoption stats across a dozen industries, from retail and higher ed to financial services and government, and explored the staggering gap between implementation and enforcement. Just because a domain has a DMARC record doesn’t mean it's protected.

If you care about customer trust, brand reputation, or just keeping your email out of the spam folder, this session is for you. Check out the ungated full recording to hear practical insights, real-world stories (like that time Valimail stopped a 2.6 million-message phishing simulation in its tracks), and what steps you should be taking now.

I hope you find it interesting!
