SendGuard was built for teams running AI agents that send email — and who've seen what happens when those agents go wrong. One bad batch. A domain blacklisted. Months of reputation work, gone.
Unlike traditional email verification tools, SendGuard is an Outbound Firewall for AI Agents — it sits between your agents and your recipients, checking every send against your outbound policy before it leaves your server. Not just "can this email be delivered?" but "should this agent send this email, right now?"
Reputation damage is hard to undo. SendGuard catches risky sends before they happen, not after the bounce reports come in.
AI agents send at scale and speed that humans can't monitor. SendGuard is designed for autonomous outbound, not just manual campaigns.
Every decision includes reason codes explaining exactly why we scored it that way. No black boxes, no surprises.
You only pay for real results. Cache hits, syntax errors, and unknown checks are always free.
