Basic translations and when to use them
There are several straightforward ways to say I’ll keep you updated in Spanish. The most common verbs are mantener, avisar, informar, and mantener al tanto. Each choice slightly changes the tone and formality.
1. Mantendré informada/os / Mantendré informado
Mantendré informada or mantendré informado is a direct and slightly formal way to say I’ll keep you informed. Use it in professional emails, customer service, or when you want to sound dependable.
Examples:
Le mantendré informado sobre cualquier cambio.
Te mantendré informada si recibo noticias.
Usage notes: Use mantendré (future of mantener) to stress commitment. Change the adjective to informada, informadas, informado, or informados to match the gender and number of the person or people addressed.
2. Te aviso / Le aviso
Te aviso and le aviso are common, informal-to-neutral ways to say I’ll let you know or I’ll notify you. Te aviso is used with friends, family, or peers. Le aviso is more polite or neutral and often used with strangers, clients, or in customer service.
Examples:
Si hay novedades, te aviso.
Cuando tenga la información, le aviso.
Usage notes: Avisar focuses on giving notice. It is shorter and more casual than mantener informado.
3. Te mantendré al tanto
Te mantendré al tanto is a friendly, conversational alternative meaning I’ll keep you up to date. It sounds natural in both spoken and written Spanish, making it useful in many situations.
Examples:
No te preocupes, te mantendré al tanto de los avances.
Te mantendré al tanto cuando la reunión esté programada.
Usage notes: Use al tanto to emphasize staying up-to-date. This phrase is casual but still appropriate in many semi-formal contexts.
4. Te informaré
Te informaré is a bit more formal and emphasizes providing information rather than just a quick notice. It works well in professional emails, reports, and when you want to assert reliability.
Examples:
Te informaré de los resultados tan pronto como estén disponibles.
Les informaré a todos los participantes por correo electrónico.
Usage notes: Use informaré when the information is substantial or official. Change to le informaré or les informaré for polite or plural forms.
Less common but useful variations
These alternatives add nuance or are preferred in specific regions.
Te iré diciendo
Te iré diciendo literally means I will be telling you as things happen. It conveys an ongoing process and is very conversational.
Example:
Mientras avance el proyecto, te iré diciendo cómo va.
Usage notes: Great for informal settings where updates will come in stages.
Te mantendré informado/a periódicamente
Te mantendré informado periódicamente specifies that updates will occur periodically. Use this when you want to set expectations about update frequency.
Example:
Te mantendré informada periódicamente con un resumen cada semana.
Usage notes: Good for project management or ongoing tasks where regular updates are expected.
Te lo haré saber
Te lo haré saber is a casual way to say I’ll let you know. It is very common in spoken Spanish and slightly more colloquial.
Example:
Si cambia algo, te lo haré saber.
Usage notes: Use in friendly conversations; avoid in very formal written communication.
Formal vs informal: pronouns and politeness
Choosing the right pronoun and verb form is important. Spanish has informal and formal ways to address people, and you need to match that register.
Informal
Use te with friends, family, classmates, and colleagues you know well. Common phrases: Te aviso, Te mantendré al tanto, Te informaré.
Formal
Use le to show respect or distance with clients, elders, or strangers. Use les for plural formal. Phrases switch accordingly: Le avisaré, Le mantendré informado, Les informaré.
Examples showing register
Informal:
Te aviso cuando termine el informe.
Te mantendré al tanto.
Formal:
Le avisaré cuando tengamos la confirmación.
Le mantendré informado sobre los próximos pasos.
Short responses and quick phrases
Sometimes you need a very short response. These are quick, natural ways to promise an update.
Ok, te aviso — I’ll let you know.
Perfecto, te mantendré informado — Perfect, I’ll keep you informed.
De acuerdo, le aviso — All right, I’ll notify you (formal).
Usage notes: Combine short phrases with a timeline when possible, for example, De acuerdo, te aviso mañana por la tarde.
Adding timelines and specifics
To be more helpful and professional, add when you will update the person or how frequently updates will come.
Common timeline phrases
mañana — tomorrow
esta tarde — this afternoon
en una hora — in an hour
la próxima semana — next week
cada día / semanalmente / periódicamente — daily / weekly / periodically
Examples:
Te aviso mañana a primera hora.
Le mantendré informado la próxima semana.
Te iré diciendo el progreso cada viernes.
Usage notes: Specifying a timeline reduces ambiguity and builds trust, especially in business contexts.
