What is a DMARC Report?
DMARC aggregate reports are XML files sent by email receivers (like Gmail, Microsoft, Yahoo) to domain owners. They contain data about emails claiming to be from your domain, including whether they passed SPF and DKIM authentication.
Why Decode DMARC Reports?
Verify Email Sources
See which IP addresses are sending email on behalf of your domain and whether they're authorized.
Monitor Authentication
Track SPF and DKIM pass rates to ensure your legitimate email is properly authenticated.
Detect Spoofing
Identify unauthorized senders attempting to impersonate your domain.
Want Automated DMARC Monitoring?
Manually decoding reports is tedious. DMARCTrust automatically collects, parses, and analyzes your DMARC reports daily.
