Free DMARC Record Generator Tool
Set a baseline DMARC policy to protect your domains. Generate properly formatted DMARC records that prevent email spoofing and improve authentication and deliverability.
Why DMARC Records Matter for Domain Protection
DMARC records provide the final layer of email authentication, telling receiving servers what to do with emails that fail SPF or DKIM checks. They protect your domain from spoofing, provide visibility into email authentication, and significantly improve deliverability.
- Prevent email spoofing by blocking unauthorized use of your domain
- Protect against phishing by ensuring only authenticated emails are delivered
- Improve deliverability by demonstrating commitment to email security
- Provide visibility through DMARC reports showing who sends from your domain
- Build trust with email providers who favor domains with DMARC policies
How DMARC Record Generation Works
Our DMARC record generator simplifies the process of creating DMARC records:
- Choose policy: Select your DMARC policy (none for monitoring, quarantine for spam folder, or reject for blocking)
- Set reporting: Specify an email address to receive DMARC aggregate and forensic reports
- Configure percentage: Set what percentage of emails the policy applies to (start with 100% for full coverage)
- Generate record: The tool creates the properly formatted DMARC record string
- Add to DNS: Copy the generated record and add it as a TXT record at _dmarc.yourdomain.com in your DNS
The generated DMARC record follows RFC 7489 standards and includes all necessary tags for proper email authentication and reporting.
