AI-Native Integration
Machine-readable JSON with risk scores, status codes, and reason fields β designed for automated processing.
When AI handles outreach, nobody watches the bounce rate. Verification has to be a pipeline layer, not a step someone remembers to run.
AI extracts emails without checking if they exist. 20-40% go to dead addresses. Every bad email wastes compute and burns sender reputation.
When AI runs outreach autonomously, nobody notices the bounce rate climbing until the domain is flagged by ISPs.
From MCP Server integration to spam trap detection, every feature works in autonomous workflows without human intervention.
Enterprise-grade email verification infrastructure designed for speed and reliability.
Whether you're building AI pipelines, validating SaaS signups, or cleaning marketing lists
