cloudflare-email-service

Send transactional emails from Cloudflare Workers by configuring a send_email binding in wrangler and invoking env.EMAIL.send within your Worker handler to dispatch messages directly through the Cloudflare Email Service.

Route inbound emails to a Worker handler by configuring email routing rules, enabling your Worker to parse incoming messages, execute custom logic, and manage forwarding or replying to the original sender.

Set up SPF, DKIM, and DMARC for Cloudflare email deliverability by completing the domain onboarding process, which configures the necessary DNS records to authenticate outbound transactional emails and manage suppression lists.

The Cloudflare Email Service works with the Agents SDK and a REST API, allowing external applications to trigger transactional email sending and integrate routing workflows without needing direct Worker bindings.

Trigger a password reset email using Cloudflare Email Service by binding the send_email service in your wrangler configuration and calling the send method with the target recipient and message payload during your user sign-up workflow.

Limitations when routing inbound emails through Cloudflare Workers include managing domain onboarding prerequisites, ensuring correct SPF, DKIM, and DMARC configurations, and handling parsing logic within the Worker execution limits.
