curl -X POST https://api.zeabur.com/api/v1/zsend/emails \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <api-key>" \
  -d '{
    "from": "sender@example.com",
    "to": ["recipient@example.com"],
    "subject": "Hello from Zeabur Email",
    "html": "<h1>Hello!</h1><p>This is a test email.</p>",
    "text": "Hello! This is a test email."
  }'

from: Must use a verified domain (e.g., noreply@example.com)
to: Array of recipient email addresses
subject: Email subject line
html: HTML body (optional if text is provided)
text: Plain text body (optional if html is provided)

The API key must have send_only or all permission. If no key exists, create one first (see API Key Management above).
