What Does “I Will Keep You Posted” Mean?
“I will keep you posted” means that you will give someone updates as new information becomes available. It tells the other person that you intend to stay in contact and let them know about important changes, progress, decisions, or developments. The phrase is commonly understood as a friendly promise to keep someone informed. It can be used when you do not have all the information yet but expect to know more later. For example, if a manager is waiting for a decision, saying “I will keep you posted” means the manager will share relevant news when there is an update. The expression is usually neutral, polite, and conversational.
Common Situations Where “I Will Keep You Posted” Is Used
“I will keep you posted” works in many everyday and professional situations. You might use it in a work email when a project is still developing, in a text message when you are waiting for plans to be confirmed, or in customer communication when you need more information before giving a final answer. It can also fit personal conversations when someone wants to know what happens next.
The phrase is especially useful when the situation is ongoing or uncertain. However, you may want an alternative when you need a more formal business tone, a warmer personal tone, or a more direct promise about when the next update will come.
Is It Professional or Polite to Say “I Will Keep You Posted”?
Yes. “I will keep you posted” is generally polite, friendly, and professional enough for many workplace situations. It sounds natural in emails, conversations with colleagues, project discussions, and customer communication. However, it has a somewhat conversational and informal feel, so a more formal phrase may be preferable in highly formal correspondence.
The expression is not overly emotional or overly direct. It simply communicates that you will provide updates. Depending on the relationship, alternatives such as “I will keep you informed” may sound more formal, while “I’ll let you know” may sound more casual and personal.
Advantages and Disadvantages of Saying “I Will Keep You Posted”
Advantages
The phrase is clear, familiar, and flexible. It tells someone that you plan to provide updates without making the sentence unnecessarily long. It works well when the timing of the next update is not yet known. And it also has a friendly tone that makes it suitable for both workplace conversations and everyday communication.
Disadvantages
The main limitation is that “I will keep you posted” can sound somewhat routine or conversational. In a very formal document, a more precise phrase may fit better. It also does not tell the reader when they should expect an update. If timing matters, a more specific expression can communicate your intention more clearly.
