Please Advise vs. Please Let Me Know – Which is Correct?
While both phrases are grammatically correct, “please let me know” is generally the more versatile, polite, and widely accepted choice in modern communication for requesting information or an update. “Please advise” often sounds formal, dated, or even abrupt, and is best reserved for specific contexts where expert guidance or instructions are explicitly sought.
Please Advise or Please Let Me Know – Which is Correct?
Both “please advise” and “please let me know” are grammatically valid phrases used to request information. However, their connotations, formality, and common usage differ significantly in contemporary English. The core distinction lies in their tone and the implied nature of the requested response.
“Please advise” is an older, more formal business idiom. It often carries an implication of seeking expert counsel, instructions, or a professional opinion, rather than just a simple piece of information. In modern usage, it can sometimes be perceived as curt, demanding, or overly stiff, especially if not softened with additional polite phrasing. Its formality can make it seem dated in many everyday professional exchanges.
“Please let me know,” on the other hand, is a universally polite, clear, and direct way to ask for any kind of information, an update, or a decision. It’s highly adaptable across various contexts, from casual to formal, without carrying the same dated or demanding undertones as “please advise.” It focuses simply on the act of being informed.
The Best Trick to Remember the Difference
Think of it this way: “Advise” sounds like “advisory board” – it’s formal, often associated with seeking expert counsel or a strategic recommendation. If you’re not specifically looking for formal guidance, it might be too strong. “Let me know” is like saying “let’s talk” – it’s open, collaborative, and simply asks for a piece of information to be shared. If you want to maintain a modern, approachable tone, “let me know” is almost always the better choice.
| Phrase | Part of Speech | Meaning | Example |
|---|---|---|---|
| Please advise | Verb phrase | Request for formal information, guidance, or instructions (often dated/formal) | “Regarding the legal implications, please advise on the appropriate course of action.” |
| Please let me know | Verb phrase | Polite request for any information, update, or decision (common, versatile) | “Please let me know if you are available for a meeting next Tuesday.” |
How to Use Please Advise
The phrase “please advise” is typically used in highly formal, official, or technical correspondence where a specific type of information, instruction, or expert opinion is required. Its tone is direct and can sometimes be perceived as demanding if not softened. It implies that the recipient possesses specific knowledge or authority to provide guidance.
Use “please advise” when:
- You are seeking formal instructions or a decision.

Etymology of the phrase Please Advise
