💡 DMARC Guide
• Start with p=none: Monitor without affecting email delivery
• Review reports: Analyze aggregate and forensic reports regularly
• Gradual enforcement: Move to quarantine, then reject over time
• SPF and DKIM required: Ensure SPF and DKIM are properly configured
• Monitor delivery: Watch for false positives when tightening policies
• NEW: Use our API for automated DMARC monitoring and integration
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that prevents email spoofing and phishing attacks.
It builds on SPF and DKIM authentication mechanisms to provide domain owners with the ability to protect their domain from unauthorized use and gain visibility into their email ecosystem.
Key Benefits:
- • Prevents email spoofing and phishing
- • Provides email authentication reports
- • Improves email deliverability
- • Protects brand reputation
- • Enables gradual policy enforcement
DMARC Policy Options
p=none
Monitor mode - no action taken on failed emails. Perfect for initial implementation and monitoring legitimate email sources.
p=quarantine
Suspicious emails are quarantined (sent to spam folder). Intermediate policy for gradual enforcement while minimizing disruption.
p=reject
Failed emails are rejected entirely. Strictest policy providing maximum protection but requires careful implementation to avoid false positives.
Frequently Asked Questions
What is a DMARC record?
DMARC records are DNS TXT records published at _dmarc.yourdomain.com that specify your domain's email authentication policy and reporting preferences.
How often should I check DMARC records?
Check DMARC records whenever you modify email authentication settings, change email providers, or notice delivery issues. Regular monthly checks are recommended.
What if my domain has no DMARC record?
Domains without DMARC records are vulnerable to spoofing attacks. Consider implementing DMARC starting with p=none policy to gain visibility into your email ecosystem.
Can I use DMARC without SPF or DKIM?
DMARC requires either SPF or DKIM (preferably both) to function properly. Implement SPF and DKIM first, then add DMARC for comprehensive email authentication.
