# all_recipients_failed (/docs/reference/errors/all-recipients-failed)



`EmailAllRecipientsFailedError` has code `all_recipients_failed` and exposes ordered adapter `failures`.

`sendPersonalized` resolves partial success. This error appears only when `accepted` would be empty.

Fallback is considered only when every recipient failure for the current route is `not_sent`, unless the caller explicitly enabled continuation after unknown delivery.

Check recipient validation, native provider rejection details available through server-side causes, and adapter capability before retrying.
