Polite Ways to Say ‘Let me know’
When you ask someone to keep you updated or share their decision, the phrase “Let me know” is direct and common. However, in professional or polite settings, it can sound a little too casual or even like a command.

For a formal email, you might say “I would appreciate your update at your earliest convenience.” For a colleague you work with daily, “Just keep me posted” works well. This guide gives you clear, ready-to-use alternatives for every situation, so you always sound respectful and professional.

The polite alternatives below soften the request by adding a respectful tone, showing patience, or expressing gratitude in advance.
Formal Alternatives for Emails
Use these when writing to a client, senior colleague, or in any official correspondence. They show respect and patience.
