Audit and validate email DNS records (SPF, DKIM, DMARC, BIMI, MTA-STS, MX) for any domain. Detect email providers, count SPF DNS lookups, grade overall health A-F, and provide fix guidance. Use when the user says 'check email DNS', 'audit SPF/DKIM/DMARC', 'email deliverability check', 'detect email provider', 'fix email DNS', 'setup email records', or 'email health score'.
