Say “Por favor, avísame” for a friendly tone, or “Por favor, hágamelo saber” for a formal tone.
You see “please let me know” often: texts, emails, group chats, school notes, and work messages. In Spanish, there isn’t one single line that fits each setting. A short phrase can feel right with a friend, but the same words can feel pushy with a teacher or a client.
This article gives you a small set of Spanish options, shows when each one fits, and helps you avoid awkward tone. You’ll get ready-to-send templates, plus a few tiny grammar tricks that make your message sound natural.
What “Please Let Me Know” Means In Real Messages
In English, “please let me know” can do a few jobs at once. Sometimes it’s a simple request for information. Sometimes it’s a gentle nudge for a decision. Sometimes it’s a way to close a message without sounding cold.
Spanish usually makes that job clearer. You choose a verb that matches the action you want: “tell me,” “let me know,” “inform me,” or “update me.” Then you pick the level of formality: tú (informal) or usted (formal).
How To Say ‘Please Let Me Know’ In Spanish For Texts And Email
If you want one safe, common option for friends or classmates, use “Por favor, avísame.” It’s short, friendly, and works in most casual chats.
If you’re writing to a professor, a customer, a landlord, or someone you treat with extra respect, use “Por favor, hágamelo saber.” It sounds polite and a bit more distant, which is what you want in formal writing.
These two phrases are a solid base. After that, you can swap the verb depending on what you’re asking for.
Friendly Tone: “Por favor, avísame”
Avísame comes from avisar (to let someone know, to notify). It’s direct without sounding harsh. In a chat, it often feels like “Shoot me a message when you know.”
Try it when the action is simple: confirming a time, sharing a file, or telling you when they’re free.
Formal Tone: “Por favor, hágamelo saber”
Hágamelo saber is built from hacer (to make/do) plus saber (to know). Word-for-word, it’s like “make it known to me,” but the real meaning is “please inform me.”
It’s common in emails and letters. It can sound stiff in a group chat, so save it for formal contexts.
When You Want The Person To “Tell You”
Sometimes “let me know” is just “tell me.” In that case, “Por favor, dime” (informal) or “Por favor, dígame” (formal) can fit. These are clear and short.
Use dime when the answer is quick. Use dígame with someone you call usted.
When You Want An Update Or A Decision
For updates, Spanish often uses “Cuéntame” (tell me, fill me in) or “Avísame cuando sepas” (let me know when you know). For a decision, try “Avísame qué decides” (let me know what you decide).
These lines feel warm and human. They fit well at the end of a message that asks for a reply.
Small Grammar Tweaks That Change The Tone
A few tiny words can soften your request. Adding “cuando puedas” (when you can) makes your message less demanding. Adding “si puedes” (if you can) does the same.
Another softener is “me gustaría saber” (I’d like to know). It’s gentle and works in formal or semi-formal writing.
Pick The Right Spanish Phrase By Situation
Choosing a phrase is easier when you decide two things first: who you’re writing to and what you want them to do. Are you asking for a detail, an update, or a decision? Are you talking to a friend, or someone you call usted?
The table below gives you a menu of solid options with the tone and best use in plain terms. Mix and match as needed.
If you are unsure, start casual, then add respect with structure: greeting, one request, and one clear “let me know” line. In formal messages, add one reason the person should reply, like timing or a deadline, so the request feels fair. In casual chat, fewer words often sound kinder. If it feels sharp when you read it out loud, add cuando puedas.
| Spanish Phrase | Best Fit | Notes On Tone And Use |
|---|---|---|
| Por favor, avísame. | Friends, classmates, casual chat | Short and friendly; works as a closing line. |
| Por favor, avísame cuando sepas. | Waiting on news or a date | Adds “when you know,” so it feels patient. |
| Por favor, hágamelo saber. | Formal email, teachers, clients | Polite and distant; better in writing than chat. |
| Por favor, dígame. | Direct question in formal tone | Clear request; pair it with the exact detail you want. |
| Por favor, dime. | Quick question with someone you call tú | Simple and direct; soften with “cuando puedas.” |
| Cuéntame cuando tengas un momento. | Asking for a fuller update | Warm tone; invites a longer reply. |
| Me gustaría saber si… | Polite request that leads into a question | Gentle opener; works well in school or work email. |
| Cuando puedas, avísame. | Polite nudge without pressure | Feels flexible; good when timing is not urgent. |
Common Mistakes That Make The Tone Weird
Spanish learners often translate word-for-word and end up sounding sharp. Here are a few traps that come up a lot, plus simple fixes.
Using Formal Words With A Casual Person
Hágamelo saber can sound stiff with close friends. If you’re chatting with someone you call tú, switch to avísame, dime, or cuéntame.
Skipping “Por favor” When The Ask Is Big
In casual chat, you can drop por favor and still sound fine. In requests that ask for time, effort, or a decision, por favor helps keep the tone polite.
Sounding Like A Command By Accident
Imperatives like dime are normal in Spanish, but they can feel like an order when your message is short. Add a softener: cuando puedas, si puedes, or a friendly closing line.
Mixing Tú And Usted In One Message
Pick one style and stick with it. If you start with usted, keep the verb forms formal: dígame, avísame does not belong there. If you use tú, keep it consistent.

Simple Swap List: Choose The Verb That Matches Your Goal
If “let me know” feels fuzzy, pick a verb that matches what you want back. This keeps your message sharp and reduces back-and-forth.
| What You Want | Spanish That Fits | Best With |
|---|---|---|
| A short answer | Por favor, dime / Por favor, dígame | Direct questions |
| An update | Avísame cuando tengas noticias | Plans, delays, changes |
| A decision | Avísame qué decides | Choices and approvals |
| Confirmation | Avísame si está bien | Times, dates, details |
| More detail | Cuéntame cuando puedas | Longer replies |
| Formal notice | Por favor, hágamelo saber | Email and letters |
Small Notes On Region And Spelling
Most learners can use the phrases in this article across the Spanish-speaking world. You may hear local favorites. In parts of Mexico and Central America, avísame is common. In parts of the Southern Cone, people may type avisame without the accent in casual messages, but the standard spelling keeps the accent.
If you are writing to a group, you might hear avísenme (informal plural) or avíseme (formal singular). Those are useful once you feel steady with avísame and hágamelo saber.
Punctuation And Accent Marks That Matter
In Spanish, question marks come in pairs: ¿…? If your line is a question, use both. Accent marks can change meaning, so keep dime and dígame distinct. The accent in por qué (why) is different from porque (because). Small details like these make your message easier to read. If typing accents is hard on your phone, long-press the vowel; it takes a second and looks careful.
Mini Checklist Before You Hit Send
Run this short check and your Spanish will sound smoother right away.
- Pick tú or usted, then keep it consistent.
- If you’re nudging, add cuando puedas or si puedes.
- Match the verb to the reply you want: a detail, an update, or a decision.
- Keep the message short and clear. Spanish doesn’t need extra padding to sound polite.
