# Email sending

Advanced patterns and examples for sending emails with Cloudflare Email Service. Most examples use the [Workers binding](https://edgetunnel-b2h.pages.dev/email-service/api/send-emails/workers-api/); the same [EmailMessageBuilder](https://edgetunnel-b2h.pages.dev/email-service/api/send-emails/workers-api/#send-method) fields (`to`, `from`, `subject`, `html`, `text`, `cc`, `bcc`, `replyTo`, `attachments`, `headers`) apply to the [REST API](https://edgetunnel-b2h.pages.dev/email-service/api/send-emails/rest-api/) as JSON in your HTTP request body. The [Send email over SMTP](https://edgetunnel-b2h.pages.dev/email-service/examples/email-sending/smtp/) example covers sending over SMTP from several languages and clients.
