Tone marks and clarity
Vietnamese uses tone marks (dấu) that change a word's meaning entirely, and the translator produces them correctly, so you don't need to add them yourself. A quick read-through helps confirm the result reads naturally.
Vietnamese also has forms of address that vary by age and relationship. Machine translation makes a reasonable choice, but for personal messages keep the context in mind.
Getting accurate results
Write complete, clearly punctuated sentences — they translate far better than fragments. Avoid slang and idioms, which rarely carry over.
For longer content, translate paragraph by paragraph, and do a round-trip check on important passages to confirm the meaning held.
