Stop Domain
Spoofing Before
It Costs You.

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.

p=none asks receivers to take no action on failing mail, which is useful for discovery but provides no protection. p=quarantine asks receivers to treat failing mail as suspicious, usually by sending it to spam. p=reject asks receivers to refuse failing mail, though receivers still decide how to handle it. InboxEagle shows which policy your record publishes and alerts you when it changes, so a move between stages never goes unnoticed.

Yes, through DMARC Processing, a separate paid product that ingests and processes your DMARC aggregate (rua) reports at volume. It does not require an Email Deliverability subscription and is priced by monthly message volume. DMARC monitoring in Email Deliverability covers the DMARC DNS record itself.

InboxEagle checks your DMARC DNS record every 24 hours and alerts you on any change, so a policy edit, a changed reporting address or a deleted record is flagged within a day of the change.

Yes. DNS monitoring checks your SPF, DKIM and MX records every 24 hours and alerts on any change, alongside the DMARC record check. It does not measure SPF or DKIM alignment on individual sends.
