Cloudflare Launches Email Service to Compete with Amazon SES, Resend, and SendGrid
Cloudflare Email Service — Private Preview Overview
During Cloudflare’s recent Birthday Week, the company announced the private preview of its new Cloudflare Email Service.
This globally managed service enables developers to send and receive emails directly from Workers using native bindings — and without API keys.

Key Features
1. Transactional Email from Workers
- Send transactional emails directly from Workers.
- Automatic DNS configuration for SPF, DKIM, and DMARC — boosting deliverability.
- Route and parse incoming emails through Workers AI.
2. Deliverability Focus
> “We’re focusing on deliverability and time-to-inbox (...) We’re tightly integrating with DNS to automatically configure the necessary records so email providers can verify your sending domain and trust your emails.”
— Thomas Gauvin, Product Manager, & Celso Martinho, Senior Director of Engineering at Cloudflare.
3. Integration with Other Cloudflare Tools
- Process incoming mail via Workers.
- Store attachments in R2 (S3-compatible object storage).
- Enqueue tasks via Cloudflare Queues.
- Local testing with Wrangler email emulation.

Sample: Sending Email with Workers
export default {
async fetch(request, env, ctx) {
await env.SEND_EMAIL.send({
to: [{ email: "hello@example.com" }],
from: { email: "api-sender@your-domain.com", name: "Your App" },
subject: "Hello World",
text: "Hello World!"
});
return new Response(`Successfully sent email!`);
},
};---
AI-Powered Workflow Connection
As AI tools become more integrated into workflows, Cloudflare’s use of Workers AI for parsing incoming email fits into a broader ecosystem of automated content creation and delivery.
Example: AiToEarn官网
- Open-source platform for AI-generated content.
- Publish to multiple networks simultaneously.
- Built-in analytics and AI model rankings (核心应用, 模型排名).
- Useful for developers creating apps with automated communications, engagement, or large-scale content delivery.
