Cloudflare Email Service
Transactional Email Sending and separate Email Routing. Workers bindings, REST credentials, destination restrictions, and incoming raw MIME have distinct contracts.
Start with the first guide, then choose a sending, receiving, or feedback task. Each walkthrough identifies permissions, operational checks, and the boundary between the service and MailKite. Refer to the official Cloudflare Email Service documentation for current platform requirements.
