DMARC Compliance: Strengthen your Email Security
Reading Time: 8 min
DMARC compliance guarantees the authentication of email sent from your domain and measures against phishing and spoofing attacks. For an email to be DMARC compliant, it has to align with either SPF or DKIM authentication. This is important for ascertaining whether the message is genuinely authorized to be sent on behalf of your domain.
With DMARC, domain owners establish security policies to combat fraudulent emails. These policies instruct email receivers to reject, quarantine, or otherwise mark suspicious emails to help in mitigating cyber threats in the form of email spoofing and phishing attacks.

Why is DMARC Compliance Important?
A report issued by Deloitte for cybersecurity suggests that 91% of data breaches are caused by phishing attacks. Implementing DMARC compliance is key for organizations to:
- Prevent Domain Spoofing and Phishing- Protecting against domain imposters and unauthorized use of their emails
- Improve Email Deliverability- Makes sure their authenticated emails are delivered solidly into the inboxes of their recipients
- Meet Compliance Standards- Validates such regulations as PCI DSS v4 and designations from Google and Yahoo for 2024 email sender requirements
- Give a Lift to Brand Trust- Grants Google a blue tick for certified domains
- To Protect the Power- Lessening fraudulent emails for their employees, partners, and clients.
What is Email Authentication?
Email authentication is a security measure that validates the identity of a sender of an email to establish that he is at risk from phishing, spoofing, and fraud. With this, one can recognize reliable senders of email using SPF(Sender Policy framework), DKIM(DomainKeys Identified Mail), and DMARC(Domain-based Message Authentication, Reporting, and Conformance). The major role of authentication is improving the email deliverability as well as protecting the brands and creating improved cybersecurity by reducing the unauthorized impersonation of emails.
Key Benefits Of DMARC Compliance
- Protect your domain from spoofing and phishing
- DMARC-compliant emails minimize the risks of impersonation attacks. The Global Cyber Alliance estimates that businesses can save up to $302,000 every year by deploying DMARC.
- Boost Email Deliverability
- Providers such as Google and Yahoo flag emails that are compliant with DMARC, making it less likely for them to be caught in the spam filter.
- Meet Industry Standards
- PCI DSS v4 requires compliance before March 2025 to legislate against any fraudulence that comes with online transactions.
- Google and Yahoo Email authentication- Necessary for bulk senders commencing February 2024.
- BIMI and Verified Checkmarks- Provides trust from a blue checkmark in Gmail.
