Secure your organization’s domain and build trust – start your DMARC compliance journey with Sendmarc today.
DMARC compliance refers to the process of implementing and maintaining the Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocol on a domain to authenticate outbound emails and guide receiving email servers on how to handle messages that fail authentication. DMARC builds on two foundational email authentication standards: Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM).
DMARC ties these two standards together by enabling domain owners to publish a DMARC record. This record instructs receiving servers on how to handle emails that fail SPF or DKIM checks and specifies where to send reports on email authentication activity.
Without DMARC, threat actors can spoof a domain and send fraudulent emails. This opens the door to phishing attacks, malware distribution, and significant damage to a brand’s reputation.
DMARC compliance helps businesses:
| Step | Description |
|---|---|
| SPF check | The receiving server verifies whether the sending IP is authorized in the domain’s SPF record |
| DKIM check | The receiving server verifies the DKIM signature to ensure the message’s integrity and authenticity |
| DMARC policy | Based on SPF and DKIM results, the receiver might apply the domain owner’s DMARC policy |
| Reporting | Authentication results are sent back to the domain owner through aggregate and forensic reports |
DMARC compliance provides multiple benefits that go beyond basic email security. These advantages support not only technical teams but also business operations, brand reputation, and regulatory requirements.
Many regulators require strong email security to meet their standards, such as the Payment Card Industry Data Security Standard (PCI DSS) v4.0 and the General Data Protection Regulation (GDPR). DMARC compliance helps support these requirements by securing emails and generating auditable reports.

Achieving DMARC compliance is a structured process that requires careful planning and ongoing management. The following steps outline how to implement DMARC successfully.
Start by publishing a DMARC record for your organization’s domain. This record includes:
p=), which can be:none: Monitoring onlyquarantine: Marks suspicious emails as Spamreject: Blocks unauthenticated emailsrua) and forensic (ruf) reportssp) and reporting percentages (pct)| Host | Type | Value |
|---|---|---|
| _dmarc.yourdomain.com | TXT | v=DMARC1; p=reject; rua=mailto:[email protected]; fo=1; |
Begin with a p=none policy to collect data without affecting email delivery. This allows your business to gain visibility into which messages are passing or failing authentication before enforcing stricter policies.
DMARC aggregate reports are XML files, which are generally sent daily by email providers. They include:
Manually reviewing these reports is difficult and time-consuming. Sendmarc automates the entire process – reading, visualizing, and analyzing DMARC data, so your company can easily identify misconfigurations, unauthorized senders, and authentication failures, as well as ensure DMARC compliance.
Once confident that all legitimate emails are properly authenticated:
This approach ensures the highest level of DMARC compliance and improves domain protection without disrupting business operations.
DMARC compliance is an ongoing responsibility. As your company adopts new tools and services, its email authentication configuration must evolve. Regularly reviewing DMARC reports ensures:
DMARC compliance isn’t just for security teams. It delivers value for:
DMARC compliance means that a domain has correctly implemented the Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocol. This includes publishing a valid DMARC record and enforcing a policy to prevent email spoofing and phishing.
Being DMARC compliant means that all outbound emails from a domain are authenticated using Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). It also means that the domain has a DMARC policy in place to guide email receivers on how to handle unauthenticated messages.
quarantine or reject for full enforcementTo know if an email is DMARC compliant, use Sendmarc’s DMARC record checker to verify that a domain has a valid DMARC record in place. The tool confirms whether a DMARC record is correctly published and provides immediate visibility into the current configuration.
If DMARC isn’t enabled on a domain, the domain becomes vulnerable to spoofing and phishing attacks. Without DMARC, receiving email servers don’t have guidance on how to handle unauthenticated emails, which increases the risk of fraud and brand damage.
