Is Your Sending Reputation Good?
Your Sender Score determines if your emails hit the inbox or the spam folder. Enter your domain or IP to audit your DNS authentication and scan your IP against global Real-time Blackhole Lists (RBLs).
Real-Time RBL Blacklist Scanning & FCrDNS Verification
Definitively benchmark your deliverability and strictly secure your global inbox placement by instantly calculating your true Sender Score in real-time. Completely bypassing flawed estimations, we execute advanced MX auto-discovery and live DNS auditing to definitively verify your cryptographic authentication (SPF and DMARC) while rigorously performing Forward-Confirmed Reverse DNS (FCrDNS) checks for valid PTR hostnames. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our high-performance backend systematically scans your active sending IP against the world's most aggressive Real-time Blackhole Lists (RBLs like Spamhaus and Spamcop), generating a precise 0-100 reputation score alongside explicit, actionable diagnostics to flawlessly remediate routing issues and prevent permanent domain blacklisting.
