# E25003 — PreferenceSenderScopeUnsupported

This channel does not support sender-scoped preferences.

- **HTTP status**: `422`
- **Type**: `validation_error`
- **Name**: `PreferenceSenderScopeUnsupported`

## What to do

Email preferences always cover the whole channel, so leave `sender_scope` out. Sender-scoped statements exist on SMS and WhatsApp, where an opt-out binds the sender it was made to.
