Spam Filter Predictor & Evaluator
Find out why your emails might be hitting the spam folder. We evaluate your domain URL against URIBLs, check your mail server IPs against DNSBLs, and audit your email authentication signals.
Real-Time URIBL, DNSBL & Authentication Diagnostics
Predict and resolve spam filter triggers in real-time. We automatically resolve your MX endpoints to underlying IPv4 addresses and execute concurrent, encrypted DNS over HTTPS (DoH) queries to audit your domain against strict URIBLs (Spamhaus DBL, SURBL) and global DNSBLs. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend evaluates your authentication signals to calculate a precise safety score, ensuring your outbound messages reach the inbox securely.
