What is DMARC?
Email is a vital communication tool for individuals and businesses alike. But, it is also a major target for cybercriminals. DMARC – Domain-based Message Authentication, Reporting & Conformance – is an email authentication protocol that can protect your email domain from being used in email scams, phishing attacks, and email spoofing. It acts as an additional layer of security that prevents unauthorized access to your email account and safeguards your online identity.
How Does DMARC Work?
DMARC works by providing a way for email receivers (such as Gmail, Yahoo, and other email clients) to check if an email is legitimate or not. It stops spoofed emails from reaching the inbox of the target recipient. It authenticates the incoming email servers by comparing the email messages with the DMARC records published by the email domain owners. It detects any discrepancies found between the email message and the DMARC record. If the email fails the DMARC tests, it is rejected, quarantined, or sent to your spam folder.

When a DMARC policy is published, it instructs the email receiver to check the SPF and DKIM authentication records of the message. If those records are passed, the message is considered legitimate, and it is delivered to the recipient’s inbox. If either of those records fails, the email is marked as unauthenticated and can be either quarantined or rejected, according to the DMARC policy provided by the domain owner.
Why DMARC is Crucial for Email Security
DMARC’s greatest value is preventing domain spoofing or phishing attacks that could damage the reputation of your brand and business. A cyber criminal can easily impersonate your brand or company to send email scams to your clients, employees, and partners, using your domain name and email address. This can result in massive financial losses, loss of trust and market share. DMARC protects your domain, brand, and reputation by detecting and blocking fake emails that claim to be sent from your domain.
Additionally, DMARC provides valuable insights into your email ecosystem. DMARC reports will give you visibility into the source of email traffic that uses your domain name and the success rate of emails that pass DMARC authentication. This information is essential for authentication performance, route analysis, and mailbox provider reputation management.
