What does this DMARC checker analyze?
Run a complete DMARC lookup and get a clear diagnosis of your DNS record, policy configuration, and deliverability impact.
DMARC record lookup
Retrieve the DMARC TXT record currently published in your DNS.
DMARC policy validation
Analyze your policy (none, quarantine, reject) and enforcement level.
SPF & DKIM alignment
Check if your domain passes DMARC alignment requirements.
Reporting configuration
Verify rua and ruf tags for aggregate and forensic reports.
DMARC errors and warnings
Detect missing records, invalid syntax, and weak configurations.
Deliverability impact
How DMARC affects authentication, domain protection, and inbox placement.
DMARC Record Examples
Here are common DMARC policies used across different email setups.
Monitoring policy
v=DMARC1; p=none; rua=mailto:dmarc@example.com
Quarantine policy
v=DMARC1; p=quarantine; pct=100; rua=mailto:dmarc@example.com
Strict reject policy
v=DMARC1; p=reject; rua=mailto:dmarc@example.com
With subdomain policy
v=DMARC1; p=quarantine; sp=reject
Partial enforcement
v=DMARC1; p=quarantine; pct=50
Full enforcement setup
v=DMARC1; p=reject; rua=mailto:dmarc@example.com
How DMARC Works and Why It Matters
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a DNS TXT record that defines how receiving servers should handle emails that fail authentication.
When an email is received, SPF and DKIM are checked, and their alignment with your domain is verified. Based on your DMARC policy, the message is accepted, sent to spam, or rejected.
A valid DMARC record improves authentication, prevents spoofing, and gives visibility into your email ecosystem. It is a critical layer of email deliverability and security.
DMARC records start with:

Common DMARC Errors This Tool Detects
No DMARC record found
Your domain has no DMARC protection.
Policy set to none
Monitoring only, no enforcement applied.
Invalid DMARC syntax
Errors in tags or formatting.
Missing reporting configuration
No visibility into authentication results.
SPF or DKIM misalignment
DMARC fails even if SPF or DKIM pass individually.
Weak enforcement policy
Low protection against spoofing and abuse.

Free DMARC Checker to Validate Your DMARC Record
Use this DMARC checker to perform a DMARC lookup, validate your Domain-based Message Authentication, Reporting and Conformance record, and detect configuration issues affecting email deliverability and domain security.
DMARC builds on SPF and DKIM to define how receiving servers should handle unauthorized emails sent from your domain. If your DMARC record is missing, misconfigured, or too permissive, your domain becomes vulnerable to spoofing, phishing, and deliverability issues.
This tool helps you check DMARC syntax, validate policy enforcement, and ensure your domain is properly protected and trusted by mailbox providers.
