What Does “I Will Let You Know” Mean?
The phrase “I will let you know” means you’ll give someone an answer or update later. It’s often used when you don’t have all the details yet. Instead of saying “yes” or “no” right away, you promise to reply after checking. It’s a polite way to keep the conversation open.

When to Use “I Will Let You Know”

You can also use it in casual talks—like when a friend asks if you’re coming to dinner. This phrase works well when you want to check your schedule or think first. It gives space to both people. Use it when you don’t want to rush but still want to reply soon. It keeps things kind and clear.
