Cultural Tip
In Brazil, asking permission with *posso* is considered polite but still informal. In a very formal written request you might prefer *seria possível utilizar o Express Mail?* or *poderia usar o Express Mail?*. Also note that brand names like Express Mail stay unchanged, but you still need the article *o* because Portuguese treats them as masculine nouns.
