Scan, diagnose, and fix domain DNS records, email authentication protocols, and deliverability issues using deterministic validation.

DNS Doctor provides an automated suite for auditing, diagnosing, and repairing domain DNS and email authentication protocols directly from AI agents. Powered by a deterministic engine rather than speculative LLM outputs, it strictly enforces RFC grammar and calculates the SPF 10-lookup limit to generate error-free records. From scanning SPF, DKIM, DMARC, and BIMI setups to tracking global multi-region DNS propagation and monitoring lookalike domains, DNS Doctor gives teams mathematically sound fixes to improve email deliverability and harden domain security.
