What is a DMARC Record?
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that enables domain owners to manage and monitor their email traffic. DMARC records act as a digital signature for your domain, ensuring that the emails you send are legitimate and not tampered by third parties.
Why are DMARC Records Important?
- Email Security: DMARC prevents email phishing attacks, which can impersonate your domain and trick your recipients into revealing sensitive information or install malware on their devices.
- Brand Protection: A strong DMARC policy ensures that your domain's reputation is protected and that your customers can trust the legitimacy of emails from your company.
- Email Deliverability: ISPs use DMARC records as a metric for evaluating the authenticity of your emails. Having a proper DMARC record increases the chances that your emails will land in your recipients' inboxes.

If your domain doesn't have a DMARC record, it leaves you vulnerable to several risks:
- Email Spoofing: Cybercriminals can use your domain to send phishing emails, making your organization an unwitting accomplice in cyber attacks.
- Brand Reputation Damage: Your domain's reputation will suffer as more spoofed emails and phishing attacks are detected, leading to a decrease in email deliverability and trust among your customers.
- Loss of Sensitive Data: Without DMARC protection, your employees and customers are more likely to fall for email scams, leading to a loss of sensitive information and potential financial damages.
Setting up a DMARC Record
Creating and implementing a DMARC record for your domain is a crucial step in securing your email communications. Follow these steps to set up a DMARC record:
- Verify Email Authentication Mechanisms: Ensure that your domain is using Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate your emails.
- Create Your DMARC Record: Generate a DMARC record by specifying your policy, email addresses for aggregate and failure reports, and desired policy actions for unauthenticated emails.
- Add the DMARC Record to Your DNS: Publish the generated DMARC record to your domain's DNS as a TXT record.
- Monitor and Analyze Reports: Review the aggregate and failure reports regularly to analyze your email traffic, authentication status, and identify potential threats.
- Adjust Your DMARC Policy: Based on the insights gained from the reports, adjust your DMARC policy to further strengthen your email security.
DMARC Record Missing Example:
Let's say your company, Example Inc., is using the domain example.com. First, your IT team would verify that SPF and DKIM authentication mechanisms are in place. Then they will create a DMARC record like this:
v=DMARC1; p=reject; rua=mailto:reports@example.com; ruf=mailto:forensic@example.com; fo=1
This DMARC record specifies that unauthenticated emails should be rejected, aggregate reports should be sent to reports@example.com, and failure reports should be sent to forensic@example.com. Once this DMARC record is published in the DNS as a TXT record, Example Inc. can then begin receiving and analyzing reports to improve their email security.
Email security is a top priority in today's digital landscape. Don't neglect your domain's DMARC record setup and leave your organization vulnerable to email spoofing and phishing attacks!
