Case Study: Australian Labor Party achieves DMARC enforcement in 28 days and protects against email impersonation with Valimail

How the Australian Labor Party stops email impersonation attacks

The Australian Labor Party, which sends over a million emails a month through multiple third‑party bulk services, faced persistent email impersonation and domain abuse—especially during high‑visibility election seasons. Phishing simulations weren’t enough, and the party needed a scalable way to stop domain hijacking and protect its communications and reputation.

Valimail delivered visibility and automated email authentication (hosted DMARC and Instant SPF™) via a local managed service partner, enabling DMARC enforcement in 28 days. Today Valimail provides continuous reporting, ongoing monitoring and onboarding support, authenticates new services and “boutique” domains during campaign peaks, and has helped the ALP significantly reduce email fraud risk.
