What Is DMARC—and Why It Matters to Email Marketers

“DMARC (Domain-based Message Authentication, Reporting & Conformance) is a critical layer of email authentication that protects your domain—and your clients’—from spoofing and phishing attacks. Without it, inbox providers may reject or flag your campaigns.”

The Cost of Ignoring DMARC

“No DMARC? You risk lower deliverability, lost revenue, and brand damage. Worse—your clients’ domains could be impersonated by attackers. That makes your platform look insecure and unreliable.”

New Deliverability Standards Require It

“Google and Yahoo now require DMARC for bulk senders. If your platform doesn’t enforce it—or at least support it—you’re putting every campaign at risk of getting flagged or bounced.”

DMARC Builds Trust with Clients and ISPs

“Clients trust you to protect their brand and reputation. DMARC shows inbox providers you’re legitimate and security-conscious. It’s no longer optional—it’s expected.”

Why Now?

“Security expectations are rising fast. DMARC is already required for many public sector domains, and it’s becoming a baseline requirement across industries. Platforms that lead on compliance will win clients—and trust—early.”
