Other Ways to Say "Please Let Me Know"
Useful alternatives to "Please let me know" include "Could you confirm...?", "I'd appreciate your thoughts on...", "Feel free to reach out if...", and "Let me know by Friday if that works." The best replacement depends on what you actually want: a decision, information, feedback, or simply an open door for questions.
"Please let me know" is a workhorse. It's polite and short, which is why it shows up in almost every email. The trouble is that it often hides the real request. "Please let me know about the meeting" could mean "Are you coming?", "Which time suits you?" or "Do you want to cancel?" Swapping in a sharper phrase saves everyone a round of back-and-forth.
Quick answer: Name the exact thing you need. For a decision: "Could you confirm by Wednesday?" For information: "Could you send me the final figures?" For feedback: "I'd welcome your thoughts." For an open offer: "Feel free to reach out with any questions." For casual chats: "Give me a shout."

What "let me know" is doing in your sentence
Grammatically, "let me know" is an imperative: let plus the object me plus the bare infinitive know. Adding "please" softens the command into a request. It can be followed by:
- a noun: "Let me know the details."
- an if/whether clause: "Let me know if you can make it."
- a wh- clause: "Let me know when you arrive / what you decide."
That flexibility is why it's everywhere. But each structure points to a different kind of request, and naming that request directly is clearer.
| What you really want | Vague version | Clearer version |
|---|---|---|
| A yes/no decision | "Please let me know about Friday." | "Can you make Friday at 2 p.m.?" |
| Specific information | "Let me know the numbers." | "Could you send the Q2 sales figures by noon?" |
| Feedback | "Let me know what you think." | "Does the second section answer the client's question?" |
| Notification | "Let me know when it's done." | "Could you ping me once the file's uploaded?" |
| Open offer of help | "Let me know if you need anything." | "If you'd like me to review the draft, I'm free Thursday." |

Example emails and messages
Scheduling a meeting
Hi Ellen,
I'd like to set up a 30-minute call to go over the Portland site plans. Does Tuesday at 10 a.m. or Wednesday at 2 p.m. work better for you? If neither suits, send me a couple of times and I'll fit around you.
Thanks, Josh
Instead of "Please let me know your availability," Josh offers two options. Choosing is easier than generating.
Requesting information from a supplier
Dear Mr. Patel,
Could you confirm the delivery date for order #48213 to our Brisbane warehouse? We need the stock by 3 June for a launch event, so if there's any risk of delay, I'd appreciate a heads-up as soon as possible.
Kind regards, Claire Dawson
Offering support after onboarding
Hi Amira,
Welcome aboard! Your laptop and logins are all set up. Over the next week, feel free to reach out with any questions, however small. I'm usually at my desk from 8:30, and I'm on Teams all day.
Cheers, Kevin
Asking for feedback on a draft
Hi Rob,
I've attached a draft of the grant application. I'd especially welcome your thoughts on the budget section, as I'm not sure the staffing costs are justified clearly enough. Could you send any comments by Monday?
Thanks so much, Lucy
A quick text
Mia: Thinking of getting tickets for the Manchester gig in June. Shout if you want to come! Hollie: I'm in! Send me the link.
More example sentences
- "Could you let me know whether the venue has step-free access?"
- "Shall I send the invoice to you or to accounts?"
- "Please keep me posted on the inspection results."
- "If the times don't work, just suggest another slot."
- "Would you mind confirming the spelling of your surname?"
- "Give me a heads-up if the train's running late."
- "I'd appreciate your input on the hiring criteria."
- "Any thoughts on the new logo before we send it to print?"
- "Let me know once you've landed in Perth."
- "If you need anything else from me, I'm around until five."
Mistakes to avoid
- ❌ "Please let me know." (with no context at the end of a long email) ✅ "Could you confirm by Friday whether the budget is approved?"
- ❌ "Please advise." (alone, after a complaint) It can sound cold or passive-aggressive. ✅ "Could you advise on how we can fix this?"
- ❌ "Let me know if you have any questions or concerns or need anything else or want to discuss further." ✅ "Happy to discuss if anything's unclear."
- ❌ "Lmk asap" to a client. ✅ "Could you let me know by 3 p.m. today?"
- ❌ "Please revert back to me." (common in some international business English, but unclear to many US/UK/AU readers) ✅ "Please reply when you can." or "Could you get back to me?"
- ❌ "Let me know if this works for you?" (statement with a question mark) ✅ "Let me know if this works for you." or "Does this work for you?"
That last one is a common slip: "let me know" is an imperative, so the sentence is a statement and takes a period. If you prefer a question mark, rephrase as a question.
When "let me know" is still the right choice
Sharper isn't always better. "Please let me know" earns its place in a few situations:
- Genuinely open offers. "If you'd ever like a tour of the Adelaide site, let me know" has no deadline and no specific request, and that's the point.
- Writing upward. Pressing a senior executive for a decision "by 3 p.m." can feel pushy. "Let me know if you'd like me to prepare anything for the board" leaves the timing to them.
- Sensitive moments. After bad news, a gentle "Let me know if there's anything I can do" puts no pressure on the reader.
- When you already gave the details. If the paragraph above spells out the question and the date, a short "Let me know" at the end simply rounds things off.
The test is whether the reader knows exactly what to reply. If they do, the familiar phrase is fine.
Editing exercise: sharpen these requests
Rewrite each vague line so the reader knows what to send and when. Suggested answers follow.
- "Please let me know about the venue."
- "Let me know regarding the invoice."
- "Please let me know your thoughts."
- "Let me know on the travel."
Suggested rewrites:
- "Could you confirm by Monday whether the Leeds venue holds 80 people?"
- "Has invoice #2207 been paid, or should I resend it?"
- "Does the pricing table on page 2 look right to you?"
- "Would you prefer the 7 a.m. or the 9 a.m. flight to Melbourne?"
US vs UK vs Australia
"Please let me know" is standard in all three countries. The informal alternatives vary most.
- United States: "Let me know," "Keep me posted," and "Feel free to reach out" are extremely common in business. "Reach out" itself is very American and has spread widely, though some readers find it jargon-like.
- United Kingdom: "Give me a shout," "Drop me a line," and "Shall I...?" sound natural. "Do let me know" (with emphatic do) is a polite, distinctly British form: "Do let me know if you'd like a copy."
- Australia: "Give me a shout," "Let me know what you reckon," and "Flick me an email" are common casual forms. "Flick" in this sense (to send quickly) is particularly Australian.
Formal phrases ("Please advise," "Kindly confirm") are understood everywhere, but in all three countries they can sound bureaucratic when a plain question would do.
Memory trick: "Know what, by when?"
Every time you type "let me know," ask yourself "Know what, by when?" If you can answer both, rewrite the sentence to include them: "Let me know which date suits by Friday." If you can't answer them, the reader won't be able to either.

Related phrasing
Requests often come at the end of an email, right before your closing line. See other ways to say "Looking forward to hearing from you" for closing sentences, and other ways to say "As soon as possible" if your request is urgent. For follow-ups when nobody let you know, try other ways to say "Just checking in".
Ask for exactly what you need
"Please let me know" is polite, but politeness works best alongside clarity. When you name the exact information you need and the time you need it by, people can answer in one reply instead of three. Keep the friendly tone, drop the vagueness, and your requests will get faster, better answers.
Frequently asked questions
Is "Please let me know" professional?
Yes. It is polite, clear and widely used in business email. The main weakness is vagueness: "let me know" what, and by when? Adding the specific information and a deadline makes it more professional.
What is a more formal way to say "Please let me know"?
"Please advise," "I would appreciate it if you could inform me," and "Kindly confirm" are more formal options. Use them sparingly, as they can sound stiff or bureaucratic in friendly correspondence.
Is "Please advise" rude?
Not inherently, but it can read as curt or impatient when used on its own, especially after a problem. Softening it, as in "Could you advise on the best next step?", usually sounds friendlier.
Is it "let me know" or "let me know if" or "let me know whether"?
All work. "Let me know if you're coming" is common and natural. "Let me know whether you're coming" is slightly more formal and makes it clearer you want an answer either way.
How do I ask someone to let me know without sounding demanding?
Give a reason and a reasonable timeframe: "Could you let me know by Thursday? That gives me time to book the room." Explaining why you need the answer makes a request feel collaborative rather than bossy.
Should I use "kindly let me know"?
"Kindly" is common in Indian and some international business English. To many readers in the US, UK and Australia it can sound formal or slightly brusque. "Could you please let me know" is a safe neutral choice.
