# List Threads

::::callout{intent="warning"}
Inboxes are currently in private beta and only available to a limited
number of users. The response shape might change before GA.

[Get early access](https://resend.com/help?type=report\&message=I+would+like+early+access+to+Inboxes.\&priority=low) if you're interested in testing this feature.

Once you have access, upgrade your Resend SDK to use the new methods:

:::code-group
```bash Node.js
npm install resend@6.28.1-preview-inboxes.2
```

```bash CLI
npm install -g resend-cli@2.22.0-preview-inboxes.2
```

A thread is a conversation within an inbox, made up of one or more messages.

## Path Parameters

The Inbox ID.

## Query Parameters

- `folder` (string) — The folder to list: `inbox`, `archive`, `spam`, `sent`, or `trash`.

- `query` (string) — Case-insensitive substring matched against the thread subject and its label names. Max length is `256` characters.

- `label` (string\[]) — Label IDs to filter by.

- `limit` (number) — Number of threads to return. Default is `20`, maximum is `100`, minimum is `1`.

- `after` (string) — The ID of the last thread on the current page. Returns the next, older page.

- `before` (string) — The ID of the first thread on the current page. Returns the previous, newer page.

## Folders

Every thread sits in exactly one folder within its inbox.

| Folder    | Meaning                                                      |
| --------- | ------------------------------------------------------------ |
| `inbox`   | The default. The thread holds at least one received message. |
| `archive` | The thread was archived.                                     |
| `spam`    | The thread was marked as spam.                               |
| `trash`   | The thread is scheduled for deletion in 30 days.             |
| `sent`    | Threads whose messages are all outbound.                     |

You can move a thread to `inbox`, `archive`, `spam`, or `trash`. `sent` is
assigned automatically.
