Better: “Thanks for letting me know” when someone gives you an update.
Why: Different phrases show different reactions, such as appreciation, interest, or agreement.
2. Using “nice to know” in a formal report
Mistake: “Nice to know that sales increased.”
Better: “It is useful to know that sales increased.”
Why: “Nice to know” is casual and may sound too relaxed in formal writing.
