📘 What Is DMARC?
DMARC (Domain-based Message Authentication, Reporting and Conformance) protects your domain from email spoofing and phishing attacks.
It works together with SPF and DKIM to ensure only authorized servers can send emails for your domain.
🛠️ How to Use This Tool
Step 1: Enter your domain name.
Step 2: Select a DMARC enforcement policy — none, quarantine, or reject.
Step 3: Add your aggregate (rua) and forensics (ruf) emails.
Step 4: Set percentage (usually 100).
Step 5: Click Generate DMARC Record to get your fully-formatted DMARC TXT record.
Step 6: Copy the record and paste it in your DNS under:
_dmarc.yourdomain.com
Tip: Reports will help you monitor who is using your domain to send emails.
