SummaryAI, from the source post

This post announces the public beta of Cloudflare Email Service, specifically highlighting the graduation of Email Sending from private beta. It details the native Workers binding for sending emails directly from Workers, including code examples and mentions of the REST API and SDKs for other platforms. It emphasizes the automatic configuration of SPF, DKIM, and DMARC for improved deliverability. The post also details how Email Sending enhances the Agents SDK by enabling asynchronous replies and secure routing, providing code examples for an `onEmail` hook and agent state persistence. New tooling for agents is introduced: the Cloudflare MCP server, Wrangler CLI email commands, and a Cloudflare Email Service skill. Finally, the open-source Agentic Inbox reference application is presented as a demonstration of building full email clients with agent automations.
