Sometimes in discussions with a friend, coworker, or client, we lack a quick response yet still wish to reassure the other party that they are not being overlooked. That’s where I’ll share with you. It’s a simple, direct commitment to follow up once you have the information, decision, or update they need.
This phrase functions as a verbal bookmark. It maintains the position in your discussion until you can provide more specifics. It’s courteous, trustworthy, and fosters trust, particularly in corporate environments where follow-through counts. Used wisely, it shows responsibility and attention. But like any promise, its power lies in fulfilling it, since the minute you say you will inform someone, you are also setting the expectation that you really will.
What Does “I Will Let You Know” Mean?
I will let you know that means you promise to share information, updates, or a decision with someone at a later time. People often use it when they are still unclear about something, events are unfolding, or they need time to double-check specifics. The phrase helps you to see that the discussion is ongoing rather than concluded once you have the required details. It gives confidence that you will follow up on the other people’s queries or issues that have been noted.
Is It Professional/Polite to Say “I Will Let You Know”?
Yes, if used correctly, I will let you know that it is often regarded as courteous and professional. It shows in formal contexts a dedication to keep the other person informed without offering either untimely or false information. In informal situations, it serves as a kind, comforting reply that maintains the flow of the conversation. Its professionalism, however, relies on follow-through; if you don’t subsequently contact the person, it might come off as indifferent or dishonest. Thank you for asking. I will let you know once I find out. Pair it with thanks or context to maintain politeness.
