Our DMARC platform explained: Architecture & integrations
Sendmarc’s DMARC platform helps you secure your domain by simplifying DMARC setup, monitoring, and policy enforcement. Generate records, analyze reports, and stop spoofing with real-time insights, all while integrating with SSO and SIEM platforms for seamless user management and security.
Strengthen your email defenses and streamline authentication with Sendmarc’s Domain-based Message Authentication, Reporting, and Conformance (DMARC) platform.
Navigating the DMARC platform architecture
Understanding DMARC is essential before using a DMARC management platform. DMARC builds on two foundational email authentication protocols:
- Sender Policy Framework (SPF): SPF allows domain owners to specify which IP addresses are authorized to send emails on their behalf. This is done by publishing an SPF record in the DNS. When an email is received, the recipient’s email server checks the SPF record to verify that the sending IP address is authorized.
- DomainKeys Identified Mail (DKIM): DKIM adds a cryptographic signature to outgoing emails. This signature is verified by the recipient’s email server using a public key published in the DNS. This ensures the email content hasn’t been altered during transit.
DMARC ties these two protocols together by specifying how receiving email servers should handle messages that fail SPF or DKIM checks. It also provides a reporting mechanism that sends feedback to domain owners about email authentication results.
How our DMARC platform architecture works
Sendmarc’s DMARC platform automates and streamlines the entire DMARC process, offering:
- DNS record management: Our DMARC platform helps generate and publish DMARC, SPF, and DKIM records with step-by-step guidance, eliminating guesswork and reducing errors.
- Data collection and processing: Receiving email servers send DMARC aggregate and forensic reports in XML format. Our DMARC management platform automatically collects, reads, and analyzes these reports, transforming complex data into actionable insights.
- Policy enforcement: Based on the insights, users can confidently enforce DMARC policies ranging from monitoring (p=none) to strict rejection (p=reject).
- SPF optimization: SPF records can become overly complex, especially for organizations using multiple third-party services. Sendmarc’s DMARC platform includes SPF flattening capabilities that optimize SPF records, ensuring they stay within the DNS lookup limit, which enhances compliance and performance.
- Threat intelligence and alerts: Our DMARC platform continuously monitors suspicious activity, such as unauthorized senders or phishing attempts, and provides real-time alerts to enable rapid response.
- Compliance support: Our solution supports compliance with regulations such as the GDPR and PCI DSS by securing email channels and providing auditable reports.
This layered and automated architecture empowers businesses to maintain a secure, compliant, and efficient email environment.
DMARC platform integrations
A powerful DMARC platform must integrate seamlessly with existing IT infrastructure and security tools. Our DMARC platform offers a range of integrations to enhance usability and security:
Single Sign-On (SSO):
Managing user access securely is critical for companies of all sizes. Our DMARC platform supports SSO integration with popular Identity Providers (IdPs), including:
- Okta
- Google Workspace
- Microsoft 365/Entra
By enabling SSO, organizations can centralize user authentication, reduce password fatigue, and enhance security.
API integration:
For businesses with complex IT environments, our DMARC platform provides full API access that enables:
- Automation of critical tasks
- Integration with SIEM systems
This API-first approach ensures that our DMARC platform can be incorporated into broader cybersecurity and IT frameworks.
Support for email authentication standards:
Beyond DMARC, the platform supports related email standards and protocols, including:
- Brand Indicators for Message Identification (BIMI): Enables brand logos to appear in recipients’ inboxes, enhancing brand recognition and trust
- Mail Transfer Agent Strict Transport Security (MTA-STS): Ensures encrypted email transport between servers, protecting messages in transit
- Transport Layer Security Reporting (TLS-RPT): Provides reports on encrypted email delivery failures, improving visibility

Benefits of using a DMARC platform
Implementing and managing DMARC without a dedicated platform can be complex and resource-intensive. Here are the key benefits of using a DMARC management platform:
Comprehensive visibility and control
Our DMARC platform transforms complex reports into clear data. Organizations gain full visibility into who’s sending emails on their behalf and how their domain is being used, enabling informed decision-making.
Simplified compliance
Email security is a critical component of regulatory compliance frameworks such as PCI DSS. Our DMARC platform provides auditable reports and helps maintain compliance by securing email channels.
Operational efficiency
Automating record management, report analysis, and SPF optimization reduces manual workload and minimizes configuration errors. This allows IT teams to focus on strategic initiatives.
Centralized user management
SSO integration simplifies user access management and enhances security by enforcing business-wide authentication policies.
Brand protection and trust
By reducing the risk of domain spoofing and enabling BIMI, brand reputation is strengthened, and customers gain confidence in company communications.

DMARC platform FAQs
What is DMARC used for?
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is used to protect against impersonation attacks. DMARC specifies how receiving email servers should handle unauthenticated messages. DMARC helps prevent phishing, spoofing, and other email-based attacks.
Is DMARC really necessary?
Yes, DMARC is necessary. It is essential for securing an email domain, improving email deliverability, and complying with the requirements of major email providers such as Google, Yahoo, and Microsoft. Without DMARC, a domain remains vulnerable to abuse.
How do I know if my DMARC is working?
Your business can find out if DMARC is working by monitoring reports collected by a DMARC platform. These reports show which emails passed or failed Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) checks, identify unauthorized senders, and provide actionable insights based on findings.
Can you send emails without DMARC?
Yes, it’s technically possible to send emails without DMARC. But, sending emails without DMARC leaves a domain open to spoofing and phishing attacks. Plus, many email providers might mark emails as Spam or reject them outright if DMARC isn’t implemented.
What happens without DMARC?
Without DMARC, attackers can impersonate a domain, tricking recipients into trusting fraudulent emails. This can result in data breaches, financial loss, and reputational damage.
