# List a user's email addresses

`GET /v1/users/{user_id}/emails` · permission `users:read`

Lists every email address of the user in one page: the primary address first, then by creation time. A user has at most 10 addresses (including the primary), so the list has no `limit`, `after`, `before` or `order`, and `list_metadata` is always `null` valued. `id` is the internal UUID of the email row, used by the other email endpoints.

## Request

| Parameter | In | Required | Description |
|---|---|---|---|
| `user_id` | path | yes | User id, prefixed `usr_`. |

The request takes no body (an empty body or `{}` is accepted).

## Response

`200 OK`. Without the `users:read_pii` permission the address is masked (`a***@e***.com`).

## Errors

Every error is an `application/problem+json` body with a stable `code`.

| HTTP | `code` | When |
|---|---|---|
| 404 | `not_found` | The user does not exist in this environment, is being deleted, or the id is malformed. |
| 401 | `unauthenticated` | The API key is missing, invalid or revoked. |
| 403 | `insufficient_permissions` | The key lacks the `users:read` permission. |
| 429 | `rate_limited` | The rate limit was exceeded; honor `Retry-After`. |
| 503 | `service_unavailable` | A dependency is temporarily unavailable; retry later. |
