What is online DMARC Generator?

The DMARC Record Generator is a powerful yet simple tool designed to help you create Domain-based Message Authentication, Reporting, and Conformance (DMARC) records for your domain. DMARC is an email authentication protocol that protects your domain from email spoofing, phishing attacks, and unauthorized email usage.

This tool automatically generates properly formatted DMARC records based on your selected security preferences. You can choose your policy level (none, quarantine, or reject), set the percentage of emails to apply the policy to, and configure email addresses for receiving aggregate and forensic reports. The generator ensures your DMARC record follows the correct syntax and can be immediately added to your domain's DNS settings.

How to use DMARC Generator?

Using the DMARC Record Generator is straightforward:

  1. Select Policy Level: Choose from three options - "None" for monitoring only, "Quarantine" to mark suspicious emails, or "Reject" to block unauthorized emails completely
  2. Set Percentage: Specify what percentage of your email traffic should be subject to the DMARC policy (default is 100%)
  3. Enter Aggregate Report Email: Provide an email address where you want to receive daily summary reports about email authentication results (rua)
  4. Enter Forensic Report Email: Optionally add an email address for detailed reports about specific authentication failures (ruf)
  5. Generate Record: Click the "Generate DMARC Record" button to create your custom record
  6. Add to DNS: Copy the generated record and add it as a TXT record for "_dmarc.yourdomain.com" in your domain's DNS settings

Frequently Asked Questions

Have questions about DMARC Generator? Find answers to the most common queries below.

A DMARC record is a DNS TXT record that tells email servers how to handle emails claiming to be from your domain. It works with SPF and DKIM to authenticate emails and prevent spoofing.
Always start with "none" to monitor your email traffic first. After reviewing reports and ensuring legitimate emails pass authentication, gradually move to "quarantine" and then "reject."
RUA (Aggregate Reports) provides daily summary statistics about all emails. RUF (Forensic Reports) sends detailed information about specific authentication failures, though many receivers don't send forensic reports due to privacy concerns.
Yes, DMARC relies on SPF and DKIM for authentication. Ensure at least one of these is properly configured before adding a DMARC record.
Start with 100% when using policy "none" for monitoring. When moving to "quarantine" or "reject," begin with a low percentage (10-25%) and gradually increase as you verify legitimate emails authenticate correctly.
After adding the DMARC record to your DNS, it typically takes 24-48 hours to propagate globally. You'll start receiving reports within a few days.
Yes, you can use the same email address for both aggregate and forensic reports, though they serve different purposes.
Add it as a TXT record in your domain's DNS settings with the hostname "_dmarc.yourdomain.com" (replace yourdomain.com with your actual domain name).
