We don't guess. We verify. See how our engineering-first approach outperforms standard industry verifiers, especially on high-risk domains.
*Data based on a sample of 1M randomly selected B2B email addresses tested against top 3 competitors. "Standard Verifiers" often return "Unknown" for Catch-All domains (0% resolution).
We utilize a proprietary "Deep-SMTP" handshake. Instead of simply checking if the server connects (Helo), we proceed to the RCPT TO stage and analyze the specific time-to-first-byte (TTFB) and packet response headers.
For Catch-All domains, we employ a behavioral analysis algorithm that sends non-intrusive signals to determine if a human is actively monitoring the inbox, without triggering spam filters.
Every quarter, we commission a third-party audit where we take a verified list of active B2B leads (confirmed via manual outreach) and run them through our system.
"Our latest audit (Q3 2024) showed a 98.2% accuracy rate, with false positives remaining under 0.5%."
