# List email template versions

`GET /v1/email-templates/{family}/{locale}/versions` · permission `email-templates:read`

Lists the versions of a slot, newest first, without their content. At most 51 are returned: the last 50 and the published one. The list is not paginated. The `ETag` header is the slot's newest version; a slot with no versions returns an empty list.

## Path parameters

| Parameter | Description |
|---|---|
| `family` | Email family, for example `verify_email` or `email_otp` (see [List email templates](list.md)). |
| `locale` | Locale tag, for example `en` or `de`. |

## Response

`200 OK` with `ETag: "3"`
