Cultural Tip
In Spain you would normally use the informal 'tú' form 'necesitas' with friends or colleagues you know well. In many Latin American countries the same form is used, but in formal business emails you might switch to the polite 'usted' and say '¿Qué detalles necesita?'. Also, Spaniards often prefer 'detalles' when talking about event planning, while Latin Americans may lean toward 'información' or 'datos' in technical contexts.
