Cloudflare has launched its Email Service in public beta, providing developers with a complete email platform for building email-native agents. The service extends beyond traditional email usage, positioning email as a core interface for AI agents that need to communicate asynchronously with users, process information, and take action on their own timeline.

The new offering includes both Email Routing (previously available) and now Email Sending, which allows agents to send transactional emails directly from Workers using native bindings or through REST APIs with SDKs for TypeScript, Python, and Go. SPF, DKIM, and DMARC records are automatically configured, ensuring emails reach inboxes without being flagged as spam.

Unlike chatbots that respond immediately, Email Service enables true agents that can process information over time, maintain state across conversations, and follow up on their own schedule. The service integrates with the Agents SDK, provides secure reply routing, and works globally on Cloudflare's network, making it accessible regardless of where agents run.
