- Using casual phrases in formal emails: “Keep us posted” may sound too relaxed for highly formal correspondence.
- Choosing overly formal language: Phrases such as “please advise” can feel stiff in a friendly conversation.
- Repeating “let us know” too often: Repetition can make otherwise polished writing feel mechanical.
- Forgetting context: A request for feedback is different from a request for a status update, so choose language that reflects your goal.
- Sounding insincere: Warm phrases should match your actual intention. Avoid overly friendly wording when you simply need factual information.
