  1. You might see the acronym written as “LMK,” “Lmk,” or “lmk,” but all spellings mean the same thing. “Lmk” (or “Let me know”) means you’re asking for information while knowing it might not be available right away—but you’re hoping for an answer soon. [1] For example:
    • Wanna grab drinks after work tomorrow? Lmk! 🍻”
    • What do you want me to bring to the party? 🎉 Lmk!”

  1. “Lmk” doesn’t necessarily demand an immediate response. Lmk is typically used to ask a question that someone might not know the answer to yet—so by sending it, you’re just asking them to reply whenever they can tell you what you want to know. [2]
    • “Lmk when you can meet up this week—I wanna hear all about your trip!”
    • Can you share the notes from today’s class with me? Lmk!! 🙏🥺”
  2. You can also use “Lmk” to ask about a decision that someone hasn’t made yet. It’s a casual way to ask them to get in touch once they have an answer for you (without putting pressure on them to make the decision too fast). [3]
    • “Hey, just curious if you decided where you want to eat tonight? 🍝 Lmk!”
    • “Lmk if you’d have any interest in seeing a movie this weekend. I’m buying! 😁”

How to Respond to Lmk

  1. When someone sends you “Lmk,” be polite and respond even if you don’t have a definite answer yet. Simply reassure them that you’re going to answer their question soon and leave it at that (or talk about something else if you want to).
    • Them: “Hey, are you free on Friday? Lmk! 😊”
    • You: “Idk what my work schedule is yet, but I’ll text you when I do!”
  2. Once you have an answer or have made a decision, send a quick reply. That way, they’ll get the information they need (and they’ll know you’re not ghosting them or forgetting about their message).
    • You: “Hey, looks like I’m free on Friday after all. What do you wanna do??”
    • Them: “Yay! Let’s hit up the bookstore and get ice cream! 🍨”

When can you use Lmk?

  1. Since “Lmk” is considered a casual abbreviation, there’s absolutely nothing wrong with using it among friends! This is true whether you’re sending Lmk over text, in an online game chat, or via a messaging app.
  2. “Lmk” is a casual term, but still more formal than acronyms like “Omg” or “Ikr.” So, use your best judgment in the workplace. If you’re sending a casual message to a colleague, Lmk might be appropriate—but in academic writing or formal requests to a boss, it isn't. [4]
    • Is your workplace culture pretty casual? Do other coworkers use acronyms? If so, you could likely use Lmk.
    • Ask yourself if your coworkers will understand what you’re saying. If not, just write the full phrase!
    • Need to use a full phrase instead of an acronym? Try similar phrases such as:
      • Please reply soon
      • Keep me posted
      • Keep me updated
      • Please get back to me
      • Please contact me
      • Notify me
