Email Deliverability Audit — SPF/DKIM/DMARC Check

Email deliverability audit API for AI agents. Analyze any domain's email authentication: SPF record validation, DKIM selector check, DMARC policy analysis, MX record health, and composite deliverability score 0-100 with prioritized fix recommendations. Tools: email_audit_deliverability. Use this when auditing email infrastructure, diagnosing delivery issues, or checking domain reputation before sending campaigns. IMPORTANT: This checks the DOMAIN's setup — for individual email validation, use email_verify_address instead. Returns: {score, spf, dkim, dmarc, mx, recommendations[]}. No API key required — x402 micropayment $0.005/call on Base L2.
