Secure Your Domain: How To Create
A DMARC Record In Minutes


Email is a vital communication tool, but it’s also a common target for cyberattacks like phishing and spoofing. Protecting your domain from unauthorized use is crucial for maintaining trust and safeguarding sensitive information. One of the most effective ways to achieve this is by implementing a DMARC (Domain-based Message Authentication, Reporting, and Conformance) record. In this guide, you’ll learn how to quickly create a DMARC record to strengthen your email security and protect your brand reputation.


What is DMARC, and Why is it Important?


DMARC is a protocol that leverages SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify the authenticity of emails originating from your domain. Its primary purpose is to help avert:

  • Spoofing: When malicious individuals dispatch fraudulent emails that appear to originate from your domain.

  • Phishing attacks: Exploiting your domain to obtain confidential data.

  • Reputation damage: Unwanted emails damaging the reputation of your brand.

Establishing a DMARC record allows you to monitor your email activity and provides guidance to the mail servers of recipients on managing emails that are not authorized. Uncover details effortlessly with just one click.

Steps to Create a DMARC Record


1. Understand the Components of a DMARC Record

A DMARC record is fundamentally a TXT entry incorporated into your DNS configuration. Its main elements include:

  • Policy (p=): Determines the action to take on unauthorized emails

  • Aggregate Report (rua=): Email address to receive DMARC aggregate reports.

  • Forensic Report (ruf=): Email address to receive detailed reports of failed emails.

  • Alignment (aspf, adkim): Specifies how strictly SPF and DKIM must align.

2. Access Your Domain's DNS Settings

Access your domain registrar or DNS hosting service, like GoDaddy, Namecheap, or Cloudflare. Go to the section for managing DNS settings, where you can see and modify DNS records. Find the option to create a new TXT record; this is where you'll set up your DMARC configuration. Make sure you have the appropriate administrative permissions to implement these changes.


3. Generate Your DMARC Record

You have the option to manually set up a DMARC record or utilize online services for assistance. Below is an illustration of a simple DMARC record:

v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-reports@yourdomain.com; aspf=r; adkim=s; pct=100; sp=none

  • v=DMARC1: Version of DMARC.

  • p=quarantine: Sets the policy to quarantine unauthorized emails.

  • rua= and ruf=: Email addresses to receive reports.

  • aspf and adkim: Alignment mode (relaxed or strict).

4. Add the DMARC Record to Your DNS

  • In your DNS settings, create a TXT record.

  • Enter the following details: Host/Name, Type, Value

  • Save the changes.

5. Validate Your DMARC Record

After establishing your DMARC record, it's important to verify it with tools such as MXToolbox, DMARC Analyzer, or other comparable services. These resources will check that your record is configured accurately, devoid of syntax mistakes, and properly disseminated across DNS servers. Validation verifies that your email authentication policies are active. Conducting regular assessments is essential for upholding the security of your domain.


Monitoring and Optimizing Your DMARC Policy


  • Analyze DMARC Reports: Consistently evaluate both aggregate and forensic reports to monitor unauthorized email actions and pinpoint the origins of misuse.

  • Adjust Policy Gradually: Begin with a no-policy approach for tracking activities, then move to implementing quarantine measures, and ultimately proceed to rejection as your assurance in the setup increases.

  • Ensure Alignment: Ensure that your SPF and DKIM configurations are in harmony with DMARC to avoid legitimate emails being marked as spam.

  • Update Reporting Addresses: Ensure that the rua and ruf email addresses remain active and are regularly monitored to provide ongoing insights into email performance.

  • Engage IT and Security Teams: Collaborate with experts to fine-tune your policy, address vulnerabilities, and adapt to evolving email threats.
