Formal Emails in Vietnamese: 4 Traps That Reveal You're Not a Native

I've read hundreds of Vietnamese business emails written by learners, and the same four mistakes show up again and again. They're not grammar mistakes — the grammar is usually fine. They're register mistakes: the sentence is correct but the politeness level is off, and a Vietnamese reader notices it in the first line. The good news? Four fixes and your email goes from "clearly a foreigner" to "safe to send to a partner." Let's go through them with real phrases: Kính gửi, Trân trọng, Xin vui lòng, and Kính thư.

Trap 1: The greeting is too casual

In English, "Dear Mr. Minh" and "Hi Minh" are both acceptable openers depending on the relationship. In Vietnamese, Kính gửi ("respectfully sent to") is the standard formal opener, and Chào is what you say to a friend or a colleague you chat with daily. Using Chào ông Minh in a first business email reads like you're already buddies — or worse, like you didn't bother.

Trap 2: You pick the wrong address term

English has one "you." Vietnamese has a whole shelf of address words, and they encode age, gender, and relationship. This is the trap that reveals a non-native fastest, because the wrong word isn't rude — it's just weird, like calling your boss "kiddo."

If you don't know the person's age, Quý ông / Quý bà or the company name is the safe route. Guessing em for a 50-year-old director is the classic disaster.

Trap 3: The request sounds like a command

English business writing loves the bare imperative: "Please send the quote." Translated word-for-word, Gửi báo giá cho tôi sounds like an order from a boss to a subordinate. The polite fix is Xin vui lòng ("please kindly") or a softening frame like Rất mong ("we would very much hope").
