General Use Cases


1. Automated Domain Management

  • Use Case: The API enables businesses to automate the addition, updating, and retrieval of domain records, making it ideal for managing multiple domains.

  • Outcome: Automation reduces human error, boosts efficiency, and ensures consistent domain configurations across the organization.

2. Proactive Security Enhancements

  • Use Case: The API helps businesses identify weak or non-compliant DMARC policies, allowing them to guide customers in strengthening their email security.

  • Outcome: Reduced risks of phishing and spoofing attacks, ensuring a secure and trustworthy communication environment.

Detailed Business Use Cases


1. Domain Management and Automation

Automating Domain Management for Multi-Domain Enterprises

  • Use Case: The DMARC Configuration API facilitates seamless domain management by automating domain record updates and additions.

  • Outcome: Reduced operational overhead, improved efficiency, and accelerated compliance with email security standards.

Centralized Management of Domain Records for MSPs

  • Use Case: Managed Service Providers (MSPs) use the API to centrally manage DMARC records and email authentication configurations for multiple customer domains. Bulk updates streamline management.

  • Outcome: Enhanced operational efficiency, improved compliance, and simplified management across customer accounts.

2. Proactive Security and Compliance

Identifying Non-Compliant Domains

  • Use Case: The API identifies domains with weak or non-existent DMARC policies (e.g., set to "None"), enabling partners or customers to take proactive steps.

  • Outcome: Reduced risk of phishing, spoofing, and other email-based threats, with strengthened email authentication practices.

Configuring DMARC Policies for New Domains

  • Use Case: The API allows businesses to programmatically update DMARC policies during onboarding, adjusting them from "None" to "Quarantine" or "Reject."

  • Outcome: Seamless domain onboarding, improved email security, and uninterrupted email operations.

Tracking Enforcement Status for Compliance Reporting

  • Use Case: Businesses track the enforcement status of all domains in a customer’s account using the API, generating compliance reports for regulators, auditors, or internal stakeholders.

  • Outcome: Transparency, accountability, and adherence to contractual obligations and regulatory compliance standards.

Domain Prioritization for Security Improvements

  • Use Case: The API retrieves domain sending statuses (e.g., "Active" vs. "Blocked") and last report dates, enabling businesses to prioritize security improvements for actively used domains.

  • Outcome: Enhanced security by focusing efforts on high-impact domains, improving email deliverability, and reducing vulnerabilities.

3. Error Detection and Monitoring

Enabling Smart Alerts for Configuration Errors

  • Use Case: Integrating the API with monitoring tools enables businesses to detect and alert customers about configuration issues, such as missing or misconfigured DMARC, SPF, or DKIM records.

  • Outcome: Faster resolution of issues, reduced risk of email delivery failures, and improved customer satisfaction.

Visualizing Netblock Coverage

  • Use Case: The API provides netblock (IP range) data associated with each domain, allowing businesses to visualize and ensure that SPF records include all legitimate email sources.

  • Outcome: Reduced chances of legitimate emails being flagged as spam due to incomplete SPF configurations.

4. Security Strategies and Sender Integrations

Managing Sender Integrations Programmatically

  • Use Case: The API simplifies linking third-party email services (e.g., SendGrid, Mailgun) to a customer’s domain. Programmatic sender connections reduce friction during integration.

  • Outcome: Faster onboarding processes, smoother customer transitions, and improved sender authentication.

Empowering Tiered Security for Customer Accounts

  • Use Case: Businesses implement a tiered security strategy by progressively transitioning domains to stricter DMARC policies, starting with less restrictive settings.

  • Outcome: Adopting best practices for stronger email security without disrupting normal operations.


The DMARC Configuration API is an invaluable tool for businesses looking to strengthen email security, simplify domain management, and improve compliance. By leveraging automation, proactive monitoring, and strategic security measures, businesses can protect their email infrastructure, reduce the risk of email-based threats, and provide a seamless experience for their customers.
