What is a DMARC Record?
DMARC is an email authentication protocol that helps protect your domain from email spoofing, phishing attacks, and other malicious email attacks. With DMARC, domain owners can specify the email authentication methods they use and inform receiving email servers how to handle emails that fail these checks.

Without DMARC, your business is at risk of becoming a target for email phishing scams, which can lead to financial loss, reputation damage, and potential legal implications. DMARC aids in:
- Protecting your brand and reputation from email spoofing
- Improving email deliverability by reducing the chance of legitimate emails being marked as spam
- Providing valuable insights into your email traffic, which can help identify potential security threats
How to Check DMARC Record
To check your DMARC record, follow these simple steps:
- Choose a DMARC record lookup tool: Several online tools are available to help you check your DMARC records, such as MXToolbox, DMARC Analyzer, and Global Cyber Alliance.
- Enter your domain: Input your domain name into the selected DMARC record lookup tool and initiate the search.
- Analyze the results: The tool will provide you with the DMARC record information for your domain. Ensure that the record is present, correctly formatted, and includes at least the v=DMARC1 tag and the p policy tag (e.g., p=none, p=quarantine, or p=reject).
- Review your policy: Ensure your policy aligns with your organization's email security requirements and best practices. For example, consider whether you want to enforce a strict policy (reject) or a more lenient policy (quarantine) for unauthenticated emails.
- Monitor and adjust: Regularly review your DMARC record, including the policy and other tags, and adjust it as necessary in response to new threats or changes in your organization's email practices.
