What Does “I Will Keep You Posted” Mean?
“I will keep you posted” means “I will continue to give you updates about a situation.”
The phrase is usually used when something is still happening or has not been decided yet.
For example:
I’m waiting for the manager’s decision. I will keep you posted.
This tells the other person that you do not have all the information yet, but you will share new information when it becomes available.
Grammar Explanation
“I will keep you posted” uses the future form “will” followed by the verb “keep.”
- I = subject
- will keep = future action
- you = person receiving the information
- posted = informed or updated
Here, “posted” does not mean putting something online. It means informed about the latest developments.
The phrase is an idiomatic expression, so its meaning cannot be understood only by looking at each word separately.
When to Use “I Will Keep You Posted”
“I will keep you posted” works in many situations. It is especially useful when you expect more information later.
At Work
You can use it when a project, meeting, decision, or problem is still in progress.
We are reviewing the proposal now. I will keep you posted on any changes.
In Emails
The phrase is common in professional emails because it sounds polite and cooperative.
We are waiting for confirmation from the supplier. I will keep you posted.
In Casual Conversations
You can also use it with friends and family.
I’m checking if I can get tickets. I’ll keep you posted.
In Spoken English
The phrase sounds natural when speaking. You can use the shorter form:
I’ll keep you posted.
The contraction “I’ll” makes the sentence sound more relaxed.
Is “I Will Keep You Posted” Professional and Polite?
Yes. “I will keep you posted” is generally professional, polite, and acceptable in business communication.
It works well with coworkers, managers, clients, customers, and business partners.
However, the phrase is somewhat conversational. If you are writing a very formal letter, legal document, or highly formal business communication, a more precise expression may be better.
For example:
Conversational professional:
I’ll keep you posted on the project.
More formal:
I will provide you with further updates as the project progresses.
Both sentences are polite, but the second sounds more formal.
Your choice should depend on the relationship, communication channel, and seriousness of the situation.

For Formal Emails

They sound less formal and more relaxed.
When You Need to Promise a Specific Action

I’ll let you know when I know more.
This avoids making a promise about a specific time.
Common Mistakes to Avoid
English learners sometimes use these expressions in ways that do not match the intended meaning.
Mistake 1: Using “Keep Me Posted” as a Formal Command
“Keep me posted” is polite in many situations, but it is conversational.
For a very formal context, consider:
Please keep me informed of any developments.
Mistake 2: Promising Updates You Cannot Provide
Do not say:
I’ll update you every day.
unless you really plan to do so.
A safer option is:
I’ll update you when I have more information.
Mistake 3: Confusing “Get Back to You” With Regular Updates
“I’ll get back to you” usually means you will contact someone again. It does not always promise several updates.
If you expect several updates, “I’ll keep you updated” is clearer.
Mistake 4: Using Very Formal Language With Friends
Saying:
I’ll keep you apprised of further developments.
to a close friend can sound unnatural.
A better choice is:
I’ll let you know what happens.
