Key Functions of DMARC Guru

  • SPF (Sender Policy Framework) Record Validation

    Example Example

    Querying the SPF record for example.com to ensure all legitimate IPs are listed.

    Example Scenario

    A business notices that some of its emails are being marked as spam. DMARC Guru verifies their SPF record and finds that not all email servers are included. The solution involves updating the SPF record with the missing IPs.

  • DKIM (DomainKeys Identified Mail) Record Check

    Example Example

    Inspecting DKIM selectors like 'google' or 'microsoft' for domain example.com.

    Example Scenario

    An e-commerce site wants to ensure that all marketing emails have DKIM signatures. DMARC Guru queries the domain for common DKIM selectors and provides recommendations on setting up DKIM for each email provider.

  • DMARC (Domain-based Message Authentication, Reporting & Conformance) Analysis

    Example Example

    Analyzing the DMARC aggregate report to identify unauthorized IP addresses sending emails.

    Example Scenario

    A healthcare company notices an increase in phishing attacks using its domain. DMARC Guru analyzes their DMARC reports, identifies unauthorized IPs, and recommends implementing a 'quarantine' policy to reduce phishing.

  • BIMI (Brand Indicators for Message Identification) Verification

    Example Example

    Querying default._bimi.example.com for the presence of a valid BIMI record.

    Example Scenario

    A SaaS provider wants to boost email engagement with its brand logo. DMARC Guru checks if their BIMI record is set up correctly and suggests improvements for better deliverability and brand visibility.

  • Custom DKIM Selector Identification

    Example Example

    Searching for selectors like 's1', 's2', 'smtp', and others used by popular email providers.

    Example Scenario

    A financial institution uses SendGrid and Outlook for transactional emails. DMARC Guru queries the domain for common selectors and provides step-by-step instructions to set up DKIM for each provider.

  • NS (Name Server) Record Identification for BIMI Management

    Example Example

    Checking _bimi.example.com for NS records to identify a third-party managing BIMI.

    Example Scenario

    A global brand outsources email authentication to a third-party provider. DMARC Guru queries for NS records at _bimi.example.com to ensure the BIMI setup is properly managed by the provider.

  • Recommendation of DMARC Providers

    Example Example

    Suggesting Valimail for comprehensive DMARC management.

    Example Scenario

    A medium-sized business needs help managing DMARC and BIMI records. DMARC Guru recommends Valimail for a seamless implementation, providing proactive monitoring and improved email deliverability.
