# List Attachments

> GET /emails/:id/attachments — list the attachments on a sent email.

`GET /emails/:id/attachments`

List the attachments on an email your account has sent. Each entry returns the attachment metadata — `filename`, `size`, and MIME fields. SendPing does not retain the original file bytes for sent mail, so `download_url` and `expires_at` are **`null`** for sent-email attachments; binary retrieval is not guaranteed. (For received mail, attachment bytes are downloadable — see [List Received Attachments](https://www.sendping.co/docs/api/emails-received-list-attachments).)

> **Note:** This endpoint is **not** paginated. Every attachment on the email is returned in one `list` response, `has_more` is always `false`, and `limit` / `after` / `before` are ignored if you send them. (The received-mail sibling, [List Received Attachments](https://www.sendping.co/docs/api/emails-received-list-attachments), *is* paginated.)

## Path parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | Yes | The id of the sent email. |

## Response fields

Each item in `data` is an attachment object:

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | No | The attachment id. |
| `filename` | string | No | The file name. |
| `size` | number | null | No | The file size in bytes, or `null` when the attachment was sent by hosted `path` URL — the size is derived from stored base64 `content`, which a URL-sent attachment does not have. |
| `content_type` | string | No | The MIME type (e.g. `image/png`). |
| `content_disposition` | string | No | `inline` or `attachment`. |
| `content_id` | string | No | The Content-ID, for inline images referenced by `cid:`. |
| `download_url` | string | null | No | A signed URL to download the file bytes. Always `null` for sent-email attachments — the original bytes are not retained. |
| `expires_at` | string | null | No | ISO 8601 time at which `download_url` expires. Always `null` for sent-email attachments. |
