Announcing Cloudflare Email Service’s Private Beta Cloudflare has launched a private beta of its new Email Sending feature, integrated into the unified Cloudflare Email Service developer platform. This offering allows developers to send transactional emails directly from Cloudflare Workers with native bindings—no API keys needed. --- Overview Email is critical for modern applications (signups, notifications, invoices, AI workflows). Managing email infrastructure is complex and frustrating for developers. Cloudflare Email Service merges sending and routing into a single, developer-friendly platform. --- Key Features of Cloudflare Email Service Simple Email Sending from Workers Add an Email binding to your Worker. Call a simple send method to send emails. Example: User Experience Focused Email is a key communication channel for users (e.g., password resets, receipts, magic links). Deliverability and timely inbox arrival are crucial; delays and spam placement degrade trust. Cloudflare integrates with DNS to automatically configure SPF, DKIM, and DMARC records for domain verification. The service is globally distributed for low-latency email delivery. Developer Friendly No need to manage API keys or secrets; emails sent with zero risk of exposed credentials. Workers handle incoming mail processing, attachment storage in R2, and task queueing for async email workflows. Local emulation of email sending with wrangler enables easy testing. Production observability includes bounce rate and delivery event tracking with debuggable delivery status. Supports integration with existing email frameworks such as React Email. Example sending HTML email using React Email: --- Email Routing and Sending: Unified Solution Email Sending is complemented by Cloudflare’s existing Email Routing. Email Routing creates custom domain email addresses and uses Workers to process incoming emails programmatically. Use cases enabled by combining sending and routing: Parse, summarize, label incoming emails with Workers AI (security flags, bug detection, auto-responses). Automatic support ticket creation in JIRA, Linear, etc. Invoice processing and attachment storage in R2. Sample Email Routing handler: This allows closing the email loop fully within Cloudflare infrastructure. --- Pricing & Availability Email Sending requires a paid Workers subscription. Pricing will be based on the number of messages sent (final details forthcoming). Email Routing remains free with unchanged limits. The platform will notify users well before billing starts. --- What’s Next Cloudflare Email Service will be available in private beta starting November. Interested
