Polite Ways to Say ‘Let me know’

When you want someone to keep you updated or share their decision, the phrase “Let me know” is direct but can sometimes sound a little casual or even demanding. In professional emails, polite conversations, or formal writing, you need alternatives that show respect, patience, and consideration. This guide gives you the best polite ways to say “Let me know,” with practical examples for emails, workplace chats, and everyday conversations.

Quick Answer: The Best Polite Alternatives

If you need a polite replacement right now, use these:

• Please keep me informed. – Best for formal emails and updates.
• I would appreciate your update. – Polite and respectful for requests.
• Feel free to share your thoughts. – Friendly and open for feedback.
• Kindly advise. – Common in professional correspondence.
• I look forward to hearing from you. – Warm and professional closing.

Why “Let me know” Can Sound Rude

The phrase “Let me know” is an imperative. It gives a direct command. While it is perfectly fine with friends or in casual chats, in formal writing or with people you do not know well, it can feel abrupt or demanding. For example, saying “Let me know if you need anything” to a manager might sound less caring than “Please feel free to reach out if you need any assistance.” The key is to soften the request by adding polite words like “please,” “kindly,” or by rephrasing the sentence to show respect for the other person’s time.
