# Update Inbox

> Update mutable fields on an inbox.

**CLI:**

```bash theme={null}
puffle email account update --id <id>
puffle email account update --id <id> --signature <signature>
```

## Overview

Update mutable fields on an inbox. Signature changes are synced to the sending backend first; if that sync fails, the DB is not updated and a 502 is returned so callers can retry without drift.

<Note>
  This operation shares the URL path `/api/email/accounts/{id}` with other verbs. See [the sibling page](/api-reference/senders/delete-email-account) for related operations on the same resource.
