Practical and clear responses make this small exchange less awkward and more useful. When someone says ‘keep me posted,’ they’re asking to be kept informed but not always telling you how — so a short, steady reply removes guesswork and sets expectations. Below are ready-to-use lines and tips to help you respond in a way that fits your time and the other person’s needs.

Why This Moment Matters

‘Keep me posted’ can sound casual, but it often carries an expectation: the person wants updates that matter to them. How you reply sets the tone for follow-up — a vague response can create missed information or unwanted interruptions, while a clear one saves time and reduces anxiety for both of you. This exchange also reveals relationship dynamics: a manager, friend, or family member may expect different levels of detail.

Short, Simple Things You Can Say

• ‘Will do — I’ll text you when I hear anything.’
• ‘Okay — I’ll send a quick update by email tomorrow.’
• ‘Sure — I’ll let you know right after the meeting.’
• ‘Got it. I’ll keep you in the loop.’
• ‘I will — do you prefer text or email?’
• ‘Thanks — I’ll give you a quick heads-up if anything changes.’

Longer Messages With More Warmth

• ‘Thanks for asking — I’ll update you as soon as there’s news and aim for a brief summary so it’s easy to scan.’
• ‘I appreciate your interest. I’ll send a short message after the decision is made and let you know any next steps.’
• ‘I’ll keep you posted. If anything urgent pops up before then I’ll call; otherwise expect a written update by Friday.’
• ‘I’ll let you know what I learn. If you want more or less detail, tell me and I’ll adjust the updates.’
• ‘Thanks — I’ll keep track of developments and send you a concise update once we have clear information.’

What to Avoid Saying

• Don’t promise specific timing you can’t keep (e.g., “I’ll update you in five minutes” unless you mean it).
• Avoid vague replies like “Okay” with no follow-up method — it leaves expectations unclear.
• Don’t overcommit to frequent check-ins if you don’t have the capacity; that leads to missed messages.
• Avoid dumping every small detail — too much noise can make the updates useless to the other person.
• Don’t assume their preferred channel; asking saves back-and-forth later.

Helpful Tips for Handling the Moment

• Ask one clarifying question: “Would you like short updates or only major changes?” — it takes one sentence and prevents confusion.
• State the method and timing when you reply: “I’ll email a daily summary” or “I’ll text if anything urgent happens.”
• Use concise subject lines or headers (e.g., “Project update: Key point”) so they can scan updates quickly.
• If multiple people are involved, decide whether updates go to the group or just to the individual who asked.
• Set a reminder for yourself to send the promised update so you don’t forget.
• If nothing has changed, send a short “no news yet” note at the agreed interval so they know you’re still monitoring.

A Note About This Particular Situation

People say ‘keep me posted’ with different levels of urgency and involvement in mind, so don’t assume they want constant contact. Clarifying once—about how often and by which channel—takes a moment and prevents more work later. Also consider the relationship: a boss may expect formal updates, while a friend probably prefers quick, casual texts.
