AI Email Validation and Outbound Firewall
Validate email addresses, score outbound risk, and stop AI agents from sending risky cold email before it damages sender reputation.

AI agents can send hundreds of emails a day. New agents start restricted and earn trust over time. Define rules per industry, intent, or recipient type. High-risk sends trigger approval requests before delivery. Route outbound through one API from Apollo, Instantly, HubSpot, Salesforce, Gmail, or your own agents.
