[Cloudflare Workers](https://workers.cloudflare.com) allow you to run serverless code globally. Since standard TCP sockets can be limited in edge environments, routing emails through the Reloop HTTP API is the recommended approach.

## Step 1: Bind Secret in Wrangler

To add your Reloop API key to your Cloudflare Worker environment securely, run the following command in your terminal:

```bash
wrangler secret put RELOOP_API_KEY
```

When prompted, input your Reloop API key starting with `rl_`.

## Step 2: Send Email via Fetch in Cloudflare Workers

Send emails with a standard POST request inside your Worker:

```typescript
export default {
  async fetch(request, env) {
    const response = await fetch('https://api.reloop.sh/v1/emails', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${env.RELOOP_API_KEY}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        from: 'alerts@yourdomain.com',
        to: 'user@example.com',
        subject: 'Edge Alert',
        html: '<p>Sent from the edge via Reloop!</p>',
      }),
    });

    return response;
  }
};
```
