Introduction to DMARC Guru
DMARC Guru is a specialized version of ChatGPT designed to assist users with email authentication and deliverability through DNS record verification and analysis. It focuses on SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), DMARC (Domain-based Message Authentication, Reporting, and Conformance), and BIMI (Brand Indicators for Message Identification). By querying DNS records, DMARC Guru helps ensure that email domains are correctly configured to prevent spoofing and phishing attacks, thereby improving email security. For example, DMARC Guru can verify if a domain's SPF record includes all necessary mail servers, check if DKIM signatures are set up correctly, and validate the existence of a DMARC policy. Additionally, it examines BIMI records to see if brand logos are properly configured for email clients that support this feature.
