The DMARC Lookup Tool by Smartlead is your first step towards securing your email outreach. This tool quickly analyzes your domain's DMARC records to identify potential vulnerabilities and misconfigurations that could affect your email deliverability and data security.
Smartlead’s DMARC Lookup Tool ensures your emails reach their target audience, protects against phishing, and boosts brand integrity.
Simply enter the domain name and press enter to get a free DMARC lookup.
DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is an email validation system that protects your domain from unauthorized use, commonly known as email spoofing.
By implementing DMARC, domain owners can specify how mail servers should handle unauthenticated emails sent from their domain. This ensures that only legitimate messages are delivered to recipients, preventing phishing and other malicious email attacks.
Why is a DMARC Check Tool Important?
A DMARC Check Tool helps domain owners verify if their DMARC record is set up correctly. This process is essential for:
- Preventing Phishing and Spoofing: DMARC helps protect your domain from being used in email fraud and phishing attacks.
- Enforcing Authentication Policies: It allows you to specify how email servers should treat unauthenticated messages from your domain.
- Improving Email Deliverability: A valid DMARC record enhances your email reputation, ensuring that legitimate emails are not marked as spam.
- Monitoring Email Traffic: DMARC provides detailed reports on email authentication, allowing you to monitor and adjust your policies accordingly.
How to Use the DMARC Check Tool?
- Enter a Domain Name: Type or paste the domain name you want to check in the input field.
- Click "Look Up": Hit the "Look Up" button to initiate the check.
- View Results: The tool will instantly display the status of the DMARC record for the entered domain. This includes any issues with the DMARC configuration and suggestions for improving email security.
Test Results: What You Will See
DMARC Record Found: If a valid DMARC record exists, you will see the authentication policy, such as “p=none,” “p=quarantine,” or “p=reject.”
DMARC Record Missing: If the domain does not have a DMARC record, the tool will prompt you to add one to enhance your email security.
Errors or Issues Detected: If there are issues in the configuration (e.g., misconfigurations or invalid syntax), the tool will highlight these problems and provide solutions for correction.

A DMARC record is a TXT record published in the DNS for your domain. A typical DMARC record looks something like this:
v=DMARC1; p=reject; rua=mailto:reports@example.com; ruf=mailto:forensic@example.com; fo=1; adkim=r; aspf=r; pct=100; sp=none; rf=afrf; ri=3600
Here’s a breakdown of what this includes:
• v=DMARC1 indicates the DMARC version.
• p=reject directs receiving servers on how to handle emails that fail DMARC checks (options include none, quarantine, or reject).
• rua=mailto:reports@example.com specifies where aggregate reports of DMARC failures should be sent.
• ruf=mailto:forensic@example.com is for sending forensic reports.
• fo=1 defines the conditions under which reports are generated.
• adkim=r and aspf=r set alignment modes for DKIM and SPF, respectively, to be relaxed or strict.
• pct=100 means applying the DMARC policy to 100% of failing emails.
• sp=none sets the policy for subdomains.
• rf=afrf defines the format of forensic reports.
• ri=3600 sets the interval for sending reports in seconds.
By customizing these values, domain owners can control how their email traffic is handled and monitored, enhancing their overall email security strategy.
DMARC Record Setup: Key Points to Consider
Policy Level: The DMARC policy determines how unauthenticated emails are treated. Common options include:
p=none: No action is taken; the report is only collected.
p=quarantine: Emails that fail DMARC checks are marked as spam or placed in the junk folder.
p=reject: Emails that fail DMARC checks are outright rejected.
Alignment: DMARC works by aligning SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records with the "From" address.
Reporting: DMARC allows you to receive reports that show how your emails are being authenticated across the internet. These reports provide insight into any vulnerabilities or potential abuse.
Regularly checking and updating your DMARC record is a critical part of maintaining secure email practices.

DKIM (DomainKeys Identified Mail) is an email authentication method that helps protect email senders and recipients from email spoofing and phishing attacks. DKIM allows you to attach a digital signature to email headers, verified via a public key in the sender’s DNS, to confirm authenticity. SPF (Sender Policy Framework) is an email authentication method used to prevent spammers from sending messages on behalf of your domain. It authorizes mail servers to send emails on behalf of your domain. It checks incoming emails against this authorization, blocking spoofing and improving email legitimacy.
DMARC ensures your emails are from a trusted source, boosting deliverability and the chances of landing in the inbox instead of the spam folder. It also protects your brand from phishing, maintains your reputation, and offers insights to optimize your email campaigns.
