Formal vs. informal 'you' and other Spanish quirks
Spanish distinguishes formal (usted) and informal (tú) "you", and it changes the verb endings. Machine translation usually picks one, so for important messages check whether the level of formality fits your relationship with the reader and adjust if needed.
Spanish also has gendered nouns and adjectives, and punctuation quirks like the opening ¡ and ¿. A translator handles these automatically, but a quick read-through helps you catch anything that should be more formal or more casual for your context.
Regional differences
Spanish varies between Spain and Latin America — and among Latin American countries — in vocabulary and some grammar (for example, vosotros in Spain vs. ustedes elsewhere). For most everyday translation the differences are minor and understood everywhere.
If you're writing for a specific audience, keep it simple and standard, which travels well across regions. For marketing or sensitive content aimed at one country, a native speaker can localize the nuances.
