Cultural Tip
In French, the imperative with attached pronouns (e.g., "tiens‑nous") is common in informal but courteous requests. It’s perfectly acceptable in professional emails when you have an established rapport. Avoid overly formal alternatives like "Veuillez nous tenir informés" unless you’re addressing a very formal audience.
