Cultural Tip
In German the imperative can sound abrupt. Adding ‘Bitte’ softens it, and in professional or customer‑facing communication the formal ‘Sie’ form (Bestätigen Sie…) is preferred. Also, German speakers often double‑check contact data because it is tied to official documents and data‑privacy regulations.
