HOW IT WORKS
This tool performs real-time DNS lookups on your domain to verify four critical email authentication records: SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), DMARC (Domain-based Message Authentication), and MX (Mail Exchange) records. Each check is scored independently, and common configuration issues are flagged with specific remediation advice.
