What is Postfleet?

AI agents are getting email but raw inboxes are an attack surface: prompt injection, spam, malicious files. Postfleet is email infrastructure for agents. Every inbound message is verified, spam/virus-screened, and checked for prompt injection before your agent reads it, then delivered already parsed and comprehended. Outbound is idempotent with optional human approval. 6 MCP tools + a REST API. Would love your feedback!
