Sending email

POST /emails accepts a JSON body (and optional Idempotency-Key).

Minimal example

{
  "from": "evre <hi@mail.evre.email>",
  "to": ["user@example.com"],
  "subject": "Hello",
  "html": "<p>Hi</p>",
  "text": "Hi"
}

Field	Notes
`to` / `cc` / `bcc` / `replyTo`	String or array of addresses
`html` / `text`	At least one body is required
`tags`	`[{ "name", "value" }]` — indexed on the message
`routeId`	Optional route (defaults to project’s default transactional route)
`scheduledAt`	ISO time — see Scheduling
`attachments`	Base64 content — see Attachments

from must use a verified domain for the project (or mock provider allowlist in local/demo).
