Common ways to say I’ll check and let you know
There are several natural options in Spanish. Each one fits different contexts: formal, informal, quick replies, or written messages. Below are the most common phrases and how to use them.
1. Lo comprobaré y te aviso
Lo comprobaré y te aviso literally means I will check it and let you know. It is neutral and appropriate for many situations, from office emails to casual conversations. Use it when you want to sound responsible and clear.
Example: Estoy viendo si hay disponibilidad.
Lo comprobaré y te aviso.
Usage note: Use te for informal you. For formal or plural, change the pronoun to le or les as needed.
2. Lo voy a revisar y te digo
Lo voy a revisar y te digo means I’m going to review it and I’ll tell you. This phrase is slightly more conversational and common in spoken Spanish. It implies you’ll take a moment to look and then report back.
Example: Dame unos minutos.
Lo voy a revisar y te digo.
Usage note: This works well in team settings or customer service when you want to sound proactive and friendly.
3. Permíteme verificar y te informo
Permíteme verificar y te informo is more formal and polite. Use it in formal emails, with clients, or in situations requiring professional tone.
Example: Gracias por la paciencia.
Permíteme verificar y te informo lo antes posible.
Usage note: Informo sounds slightly more official than aviso or digo.
4. Lo investigo y te cuento
Lo investigo y te cuento suggests you’ll look into something that may require research. It is informal and friendly, often used when the issue needs more than a quick check.
Example: No estoy seguro del proceso.
Lo investigo y te cuento mañana.
Usage note: Use this when the task may take longer; it sets the expectation of follow-up.
5. Te lo confirmo luego
Te lo confirmo luego is a succinct, casual way to say I’ll confirm later. It works in quick chats or text messages when you want to promise a follow-up without formality.
Example: ¿Hay reunión hoy a las 3?
Te lo confirmo luego.
Usage note: Avoid in very formal emails; prefer le confirmo más tarde for formal contexts.
Formal vs informal variations
Choosing the right pronoun and verb form is important to match the level of formality. Here are the main adjustments.
Informal singular
Use te and the tú verb forms. Examples include Te aviso, Te digo, and Te lo confirmo.
Example: Si puedo asistir,
te aviso.
Formal singular
Use le and usted verb forms. Examples: Le confirmaré, Permítame verificar y le informo.
Example: Gracias por su mensaje.
Permítame verificar y le informo.
Plural
For addressing multiple people, use les and ustedes verb forms. Examples: Les avisaré, Les confirmo.
Example: Revisaré los horarios y
les aviso mañana.
Common short replies for texts and chat
In informal messaging you often want quick, natural replies. Here are compact options and how they sound in everyday chat.
Short, informal
Te aviso, Te digo, and Lo veo y te digo are quick responses that mean you’ll check and reply. Use them in WhatsApp, SMS, and Slack.
Example: ¿Compraste las entradas?
Te aviso.
Short, formal
Le confirmo or Lo confirmaré suit professional chat or email threads. They keep the tone polite and concise.
Example: ¿Puede confirmar el monto?
Le confirmo a la brevedad.
Polite softeners and timeframes
Adding softeners or time expectations makes your message clearer and more courteous. Common words include ahora, en un momento, más tarde, a la brevedad, and mañana.
Examples with timeframes
Ahora mismo lo compruebo y
te aviso en unos minutos.
Lo verificaré y
te informo a la brevedad.
Lo investigo y
te cuento mañana por la mañana.
Using polite softeners
Preface with gracias por esperar or con gusto to sound courteous. Examples:
Gracias por su paciencia,
permítame verificar y le informo.
Con gusto lo veo ahora y
te digo en seguida.
Useful verbs and subtle differences

Revisar

Tips to sound natural and polite
Follow these quick tips to use these phrases like a native speaker.
1. Match formality: Use te for friends and colleagues, le for formal situations, and les for plural.
2. Add a timeframe: People appreciate knowing when you’ll reply. Use phrases like en un momento, más tarde, or a la brevedad.
3. Use softeners: Words like por favor, gracias por esperar, and con gusto make your message friendlier.
4. Be concise in chat: Short phrases are fine in text messages, but in email include a polite opening and closing.
Common mistakes to avoid
Beginners make a few predictable errors. Watch out for these so your message is clear and natural.
Using the wrong pronoun
Don’t mix formal and informal pronouns. Saying te in a formal email to a client can be seen as disrespectful. Match pronoun to relationship.
Overusing literal translations
Avoid literal translations like I’ll check translates as Voy a checar in some regions, which is acceptable informally but sounds anglicized. Prefer revisar, comprobar, or verificar in more contexts.
Not giving a timeframe
Simply saying you’ll check without saying when can leave people waiting. Add a short timeframe to set expectations.
Quick reference list

Lo comprobaré y te aviso — neutral, good for many contexts.
Lo voy a revisar y te digo — conversational, common in speech.
