What Does “I Will Keep You Posted” Mean?

The phrase “I will keep you posted” means you are promising to provide someone with ongoing updates or new information as a situation develops. It’s a commitment to stay in communication and make sure the other person isn’t left wondering what’s happening.

The word “posted” here comes from an older sense of the word think of a notice board or public posting where information is pinned for people to read. Over time, the idiom evolved to mean keeping someone regularly informed.

In short: When you say “I’ll keep you posted,” you’re saying:

• I haven’t forgotten about you
• I’ll share updates as they become available
• You can count on me to stay in touch

It works across personal, professional, and formal contexts, making it one of the most versatile communication phrases in everyday English.

When to Use “I Will Keep You Posted”

Knowing when to use this phrase is just as important as knowing what it means. Here are the most common situations where it fits naturally:

• During an ongoing project When the outcome isn’t final yet and you want to keep someone informed of progress
• After a meeting or call When next steps are still being worked out
• When waiting on third-party information Such as waiting for a vendor, doctor, or colleague to respond
• In job applications or interviews When results or decisions are still pending
• Personal situations Like telling a friend you’ll update them about travel plans, a health update, or event changes
