EasyDMARC Domain Scanner is a free, web-based tool that performs a health check on a given domain by analyzing its email authentication records. Users enter a domain name and the tool scans and returns the status of the following DNS-based records: - **SPF (Sender Policy Framework):** Detects presence, configuration issues, and provides instructions for validation and correction. - **DKIM (DomainKeys Identified Mail):** Checks DKIM selectors, identifies issues, and provides implementation guidance. - **DMARC (Domain-based Message Authentication, Reporting & Conformance):** Looks up and evaluates DMARC record status, flags misconfigurations, and offers remediation steps. - **BIMI (Brand Indicators for Message Identification):** Verifies BIMI record presence and configuration, including logo and VMC certificate requirements. The scanner identifies "Empty Record" conditions where a protocol is not yet implemented, and provides step-by-step remediation instructions for each missing or misconfigured record type. Results are used to assess domain security posture, email deliverability health, and compliance with email authentication standards. The tool is positioned as a diagnostic starting point, with guidance directing users toward EasyDMARC's broader platform for ongoing DMARC reporting, SPF generation, DKIM key generation, and BIMI logo conversion.
