Cloudflare wires email into agents
Cloudflare shipped Email Service for Agents today. The pitch is simple — your agent should be able to send, receive, and act on email as naturally as it makes an HTTP call.
The new piece is Email Sending, now in public beta. Email Routing (the inbound side) has been free for years. Combined, you get bidirectional email on one platform. Agents can dispatch transactional mail via a Workers binding or REST API, and receive inbound mail routed to specific agent instances based on the address.
The Agents SDK side is where it gets interesting. A native onEmail hook. Your agent wakes up on inbound mail, does whatever orchestration, responds async. Cloudflare ships an open-source Agentic Inbox reference app with conversation threading and MCP server support — the blueprint for customer support agents, invoice processors, account verification flows. Email as an agent surface, not an integration.
SDKs for TypeScript, Python, Go. MCP server access so Claude Code, Cursor, and Copilot can drive it directly. Wrangler CLI for the bash-accessible path.
The bigger picture. Cloudflare has been quietly turning Workers into an agent runtime — Durable Objects as agent state, Browser Rendering, now Email. They're building the email-phone-web triangle every autonomous business agent needs to actually operate in the world. https://blog.cloudflare.com/email-for-agents/
