# Add a sender

`POST /v1/email/senders`

## Request

- Base URL: `https://api.samva.dev`
- URL: `https://api.samva.dev/v1/email/senders`
- Auth: API key in header `x-api-key`

Creates a sender. A sender on a domain takes the domain's namespace, and a `namespaceId` that names another namespace is refused; a sender with no domain joins `namespaceId`, or its key's namespace. A namespace-scoped key cannot add a sender on a domain outside its namespace. The required Idempotency-Key replays the original sender for an identical request and conflicts when reused with different input.
