Announcing Cloudflare Email Service’s private beta

This post announces the private beta of Cloudflare Email Sending, a new capability allowing transactional emails to be sent directly from Cloudflare Workers. It expands upon the existing Email Routing product to form the new Cloudflare Email Service. Key technical contributions include: a new `Email` binding for secure credential management within Workers, automatic DNS record configuration (SPF, DKIM, DMARC) for deliverability, global low-latency delivery, local emulation via `wrangler`, and observability features for bounce rates and delivery events. It also details integration with external services via REST APIs or SMTP, and support for rich HTML emails using frameworks like React Email. The post also reiterates the capabilities of Email Routing for processing incoming emails with Workers, including AI-powered classification and integration with other services.
