Check Authenticated Received Chain (ARC)
Enter your domain and ARC selector to instantly validate the cryptographic keys used to seal your forwarded messages and mailing list distributions.
Real-Time Cryptographic Tag & DMARC Survival Diagnostics
Ensure your forwarded emails and mailing list distributions survive strict DMARC checks. We execute direct, encrypted DNS over HTTPS (DoH) queries to instantly validate your ARC-Seal cryptographic keys, parse exact v=, k=, and p= tags, and evaluate RSA or Ed25519 key strength. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend bypasses local caches to secure your message routing and preserve original authentication results perfectly.
