DMARC Monitoring

Stop Domain
Spoofing Before
It Costs You.

Q: What is DMARC and why does it matter for email deliverability?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that tells receiving mail servers what to do with emails that fail SPF or DKIM checks. A properly enforced DMARC policy (p=reject) prevents domain spoofing and phishing, while also signaling strong sender trustworthiness to ISPs — directly improving inbox placement rates.

Q: What is the difference between p=none, p=quarantine, and p=reject?

p=none monitors without taking action — useful for discovery but provides no protection. p=quarantine sends failing emails to spam folders. p=reject is full enforcement — failing emails are outright rejected. InboxEagle guides you from none → reject safely, ensuring all legitimate sending sources are authorized before you tighten the policy.

Q: How does InboxEagle parse DMARC aggregate reports?

Major mailbox providers (Google, Microsoft, Yahoo, etc.) send XML aggregate reports to your rua address. InboxEagle automatically collects, parses, and visualizes these reports — no manual XML wrangling needed. You see pass/fail rates, top sending sources, and alignment status in a clean dashboard updated daily.

Q: How quickly do I get alerted when DMARC alignment fails?

InboxEagle checks alignment health continuously and fires alerts within 2 minutes of a spike in failures. Each alert includes the sending IP, the mail service, the failure reason, and recommended remediation steps.

Q: Does InboxEagle monitor DMARC for sub-domains too?

Yes. We monitor your apex domain and all active sub-domains. Spoofing attacks often target sub-domains that lack explicit DMARC policy, so full coverage is critical for complete brand protection.

Full DMARC visibility — from p=none discovery to p=reject enforcement. Know every source sending on your domain, catch alignment failures instantly, and build the ISP trust that lands emails in the primary inbox.

The Difference

Blind to DMARC vs. Fully Protected

A domain without DMARC enforcement is an open invitation to spoofing, phishing, and deliverability damage.

Without InboxEagle

Domain spoofing detected — no action taken

p=none policy never progressed
Spoofed emails reaching customers
Unknown unauthorized sending sources
No aggregate report parsing
Brand trust eroded silently

With InboxEagle

p=reject Active

Full policy progression from none → reject
All spoofing attempts blocked at delivery
Every sending source discovered and logged
Aggregate reports parsed and visualized daily
Instant alerts on alignment failures
