Keep me posted is a phrase that means tell me the latest news as things develop. To use keep me posted in a sentence, name what you want updates about and keep the words in that fixed order: “Keep me posted about the delivery.”
Keep me posted at a glance
- Keep me posted is a fixed phrase made of keep, a pronoun and the participle posted.
- It means to keep someone informed as a situation changes.
- Only the pronoun varies: keep me, keep us, keep you, keep her posted.
- It belongs to email, messaging and conversation rather than formal reports.
- The commonest error is writing keep me posting or keep me post instead of posted.
What does keep me posted mean?
Keep me posted means keep me informed about something as it develops, and it promises an exchange of updates rather than one final report. The Cambridge entry for keep me posted treats it as a set expression for regular news, and the word posted here means informed rather than put in the mail. When the request is urgent, notify is sharper, and when it is routine, update does the same work.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Ask for ongoing news | Tell me each time something changes | Keep me posted about the repairs. |
| Promise to update | I will report back as things move | I’ll keep you posted on the results. |
| Request a single key fact | Let me know the moment it happens | Keep me posted the minute they call. |
One honest limitation matters. Keep me posted asks for information but does not say how often, so a busy reader can take it as vague. Where a deadline is involved, a plain request such as please send the figures by Friday is clearer, and the phrase works best for news that genuinely unfolds over time.
How do you use keep me posted in a sentence?
The phrase is nearly fixed, and only the pronoun between keep and posted moves. That slot takes me, us, you, him or her, and posted never changes to post or posting. It works as a direct instruction, as in keep me posted, and as a promise, as in I will keep you posted, with on or about introducing the subject.
The register is friendly and forward-looking, which is why it fills so many work emails. Choose inform when the tone should be more formal, and keep the phrase for colleagues, clients and friends who expect a running commentary.
| Pattern | Example | What it signals |
|---|---|---|
| keep me posted | Keep me posted about the timetable. | The standard instruction, warm and open-ended. |
| keep + pronoun + posted | Please keep us posted on the delivery. | Only the pronoun changes; posted stays fixed. |
| I’ll keep you posted | I’ll keep you posted after the meeting. | A promise to report back, not a request. |
| keep me posted + on / about | Keep me posted on any change. | On or about names the subject of the updates. |
| kept me posted | She kept me posted throughout the move. | Past tense for a stream of updates already given. |
Keep me posted in a sentence: examples across contexts
The phrase keeps one meaning wherever it appears, but the subject of the updates changes with the setting. The nine sentences below move from a family chat to a project board, and each keeps keep and posted in place while the pronoun and the topic change.
| Context | Example sentence | Why this works |
|---|---|---|
| Family conversation | Keep me posted about your train times, and I’ll meet you. | A warm request tied to a practical plan. |
| Workplace email | Please keep me posted on the client’s decision. | The polite form that suits a professional thread. |
| Team stand-up | Keep us posted if the build fails again. | Directs updates to a whole group. |
| Customer service | I’ll keep you posted once the part arrives. | A promise that reassures without overpromising. |
| Job search | They promised to keep me posted after the interview. | Reported speech, common in career writing. |
| Medical note | The clinic agreed to keep her posted on the test results. | Shifts the pronoun to a third person. |
| Volunteer group | Keep us posted about the fundraising total. | Fits an informal, collective audience. |
| Landlord email | Keep me posted on the plumber’s visit. | Keeps a routine domestic exchange courteous. |
| Project board | We kept the sponsor posted at every stage. | Past tense for a record of steady updates. |
Two small habits make the phrase sound natural. First, follow it with on or about so the reader knows what to report, because keep me posted on the budget says far more than the bare phrase. Second, match the pronoun to the audience, using us for a group and you when you are the one promising to report back. A written request can also soften the instruction with please, and a reply such as thanks for keeping me posted quietly acknowledges the updates without promising anything further.
Keep me posted vs keep me informed
Keep me posted and keep me informed mean almost the same thing, but keep me posted is warmer and more conversational, while keep me informed is the formal version that suits official writing.
| Attribute | keep me posted | keep me informed |
|---|---|---|
| Tone | Friendly and spoken | Neutral and formal |
| Implied rhythm | Updates as things happen | Updates when appropriate |
| Typical setting | Email, chat, conversation | Reports, contracts, policy |
| Fixed word | posted never changes | informed never changes |
| Formal synonym | Keep me in the loop | Apprise me of developments |
Verdict: choose keep me posted for everyday and business email, and keep me informed when the writing must stay formal; a very formal equivalent is apprise.
Word forms and grammar of keep me posted
The phrase is fixed except for the pronoun, so the useful variations are few and easy to learn. The participle posted is doing the work of an adjective, and keep here means cause to remain, which is why the pronoun sits between the two words.
| Form | Part of speech | Example |
|---|---|---|
| keep me posted | phrase, base form | Keep me posted about the schedule. |
| keep us posted | phrase, collective | Keep us posted on the decision. |
| keep you posted | phrase, promise | I’ll keep you posted. |
| kept me posted | phrase, past tense | He kept me posted all week. |
| keeping me posted | phrase, continuous | Thanks for keeping me posted. |
| kept posted | phrase, passive | We were kept posted by text. |
What may not vary is the participle: posted never becomes post or posting. The phrase can also open a message as a short imperative, which is why it survives so well in subject lines and chat, where the topic is already clear and only the reminder needs saying. Where a related but lighter goodbye is wanted, keep in touch fits, though it asks for friendship rather than news.

Frequently asked questions about keep me posted
Is keep me posted formal?
It is semi-formal and very common in workplace email, sitting comfortably between a casual text and a stiff report. Most colleagues read it as friendly and professional at once, but a legal contract or a policy document would usually prefer keep me informed instead.
What does posted mean in keep me posted?
Here posted means informed or up to date, not sent by mail. The image comes from posting a notice so everyone can see the latest news, and the phrase has kept that sense of circulating updates, which is why it pairs so naturally with the word about.
What is the difference between keep me posted and keep in touch?
Keep me posted asks for news about a specific situation, while keep in touch asks to preserve a relationship with no particular topic. You keep me posted about a house sale; you keep in touch with an old friend, and the first request ends when the situation resolves.
Should I write posted on or posted about?
Both are correct, and the choice depends on the noun. Use on for topics, decisions and events, as in keep me posted on the decision, and about when the update is general news, as in keep me posted about the trip. Neither is more formal than the other.
