# Parameter :: 10. `email::`
Controls whether the email address line appears in output. Source for `.credentials.status`: `emailAddress` field in live `~/.claude.json`. Source for `.accounts`: `emailAddress` field in saved `{name}.json` snapshot.
- **Default:** `1` (shown)
- **Constraints:** Accepted values: `0`, `1`, `false`, `true`
- **Purpose:** Allows suppression of the email line; shows `N/A` when the source file is absent or `emailAddress` is empty.
**Examples:**
```text
email::1 → Email: alice@acme.com (default; N/A when absent)
email::0 → line omitted
```
