- Industry-wide enforcement jumped 10 points in 2025 and more than 75% of domains have valid DMARC records, showing strong adoption progress
- More than 40% of domains still aren’t enforcing DMARC, leaving room for spoofing and fraud
The State of DMARC in 2026: Healthcare works to close inbox exposure gap
Provider emails are trusted by default, which is exactly what attackers count on.
Healthcare isn’t just another high-volume email environment. It’s personal and crucial, with patients relying on email for lab results, billing notices, appointment reminders, and insurance updates. Patients aren’t second-guessing provider messages, and that’s exactly why attackers target this industry.
Our 2026 report shows that healthcare organizations understand the risk. Enforcement rates are strong, adoption is widespread, and more organizations are moving in the right direction.
But here’s the reality: Even a small gap creates an opening. If your domain isn’t at enforcement, attackers can still send convincing messages that look like they came from you. And in healthcare, patients are more likely to trust those messages and get taken advantage of.
That’s what raises the stakes here. DMARC enforcement is about protecting the communication patients rely on to manage and sustain their health.
Security is just one more way you can safeguard your patients.
