DMARC is Protecting Your Domain and Brand

Email authentication isn’t complete without full visibility and control over who is sending email on your behalf. DMARC adds this final layer of protection, helping secure your domain against phishing and abuse.

What Is DMARC (Domain-based Message Authentication, Reporting & Conformance)?

DMARC works together with SPF and DKIM to give domain owners full control over unauthenticated emails. It tells email providers what to do if a message fails authentication (reject, quarantine, or allow), and it provides reporting on who is sending email using your domain.

Why DMARC Matters

DMARC protects your domain from phishing, spoofing, and abuse. It gives you full visibility into your domain’s email traffic - helping you spot problems early and protect your customers.

Example of DMARC in Action

You add a DMARC policy to your DNS. If an incoming message fails SPF or DKIM, the policy tells inbox providers how to handle it - for example, to reject or quarantine the email.
