What it does
The specific capability behind this listing, and where to get it.
Secure email infrastructure for AI agents. Every inbound message is verified, sanitized, and screened for prompt injection before your agent reads it — hidden HTML, zero-width characters, and decode-then-apply payloads are stripped or fail closed — then delivered as typed JSON. Outbound send is idempotent, with optional human approval on consequential replies.
