DMARC XML & TLS-RPT Report Analyzer

Decode aggregate DMARC XML reports (.xml, .gz) and SMTP TLS-RPT JSON reports to analyze sending IP compliance, SPF/DKIM alignment, and transport encryption failures.

Report Compliance Score

Average SPF/DKIM validation alignment success rate.

About DMARC & TLS-RPT Reports

DMARC Aggregate Reports (rua) are daily XML documents sent by mailbox providers (Google, Microsoft, Yahoo) detailing email authentication pass/fail rates for messages sent using your domain. TLS-RPT Reports (rua) are JSON reports outlining SMTP TLS encryption handshake successes and failures across inbound mail servers.

Why Analyze Email Reports?

Identify unauthorized third-party senders or spoofing attempts targeting your brand.
Audit SPF and DKIM alignment gaps across legitimate marketing platforms and transactional mailers.
Detect certificate expiration, untrusted CA chains, or expired STARTTLS ciphers affecting email delivery.

Relevant Standards

DMARC reporting is governed by RFC 7489, while SMTP TLS Reporting follows RFC 8460.
