DMARC, short for Domain-based Message Authentication, Reporting, and Conformance, works by verifying the source of an email and determining the appropriate action. This security protocol ensures that only emails from legitimate sources are delivered.
Achieving DMARC compliance gives your company full visibility and control over all emails—both legitimate and potentially fraudulent—claiming to be from your organisation.
What is DMARC and How Does it Impact Businesses?
DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is a security protocol that verifies the source of an email and determines how it should be handled. By allowing only emails from authorised sources to be delivered, DMARC acts as a protective measure against phishing and other email-based attacks.
Achieving DMARC compliance provides your business with complete visibility and control over all emails—both legitimate and unauthorised—claiming to originate from your organisation.
Understanding DMARC’s Impact on Business Emails
Email remains the primary risk channel for businesses, with phishing emails responsible for 84% to 91% of security incidents. This makes phishing the leading cause of data breaches. To address this threat, the global security standard DMARC was established, ensuring that only verified emails reach recipients. However, businesses that do not meet DMARC requirements may face disruptions in email delivery, underscoring the importance of compliance for secure and reliable email communication.
To address the growing threat of email-based cyberattacks, a global security standard known as DMARC was established by leading FinTech companies, including AOL, Google, Microsoft, Yahoo, LinkedIn, JPMorgan Chase & Co., and PayPal.
DMARC leverages DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) to authenticate incoming emails, effectively reducing the risk of malicious messages reaching recipients.
In a further step to enhance security, Google and Yahoo mandated DKIM or SPF alignment for authentication starting in February 2024. This requirement significantly impacts non-compliant organizations, as their emails may be rejected or blocked.
Additionally, beginning in March 2025, DMARC compliance will become mandatory under PCI DSS v4.0. This requirement will apply to all organisations processing payments, necessitating the implementation of DMARC, SPF, and DKIM to protect against phishing attacks and reduce cyber risks.
To enhance email security and ensure DMARC compliance, Advantage offers Managed DMARC. Utilising advanced email threat technology, our solution meets the needs of modern businesses by implementing DMARC standards along with SPF and DKIM.

Managed DMARC ensures that your business email communications comply with the latest DMARC authentication standards, protecting your domain from impersonation.
In addition to safeguarding your brand, Managed DMARC enables your business to meet the requirements of PCI DSS v4 (Section 5.4), which mandates anti-phishing measures to protect cardholder data during payment transactions.
DMARC reporting provides insights into both legitimate and unauthorised uses of your email domains.
