Cloudflare Email Service enters public beta

Native email bindings in Workers and Agents SDK enable bidirectional email workflows without secrets management or DKIM/SPF boilerplate.

Summary

Developers building email-native agents (support, invoice processing, verification flows) now have receive + send + state persistence in one platform, eliminating the need to stitch email through external services. SPF/DKIM/DMARC auto-configuration removes the compliance tax.

Why it matters

Implementation verdict

Replaces Sendgrid/Mailgun for transactional email in Workers; replaces custom email routing logic for agents. Requires Cloudflare account and domain verification. Ready now—public beta with Workers binding and REST API/SDKs (TypeScript, Python, Go). Best fit if you're already on Cloudflare or building Agents SDK workflows.
