17+ Other Ways to Say “I Will Keep You Posted” (Formal, Informal & Professional Alternatives)

Last updated: November 1, 2026

“I will keep you posted” is one of the most overused lines in English emails, texts, and workplace chats. It’s not wrong — it’s just tired. If you type it in every single message, your writing starts to sound like a template instead of a person.

This guide gives you 17+ other ways to say “I will keep you posted,” sorted by tone: formal, professional, and casual. You’ll also learn the grammar behind the phrase, the mistakes people make with it, and how to pick the version that actually fits your reader.

I’ve edited hundreds of client emails and student drafts over the years, and this exact phrase comes up constantly — usually repeated three or four times in the same thread. A little variety fixes that fast.

What Does “I Will Keep You Posted” Mean

“I will keep you posted” means you’re promising to give someone updates as new information becomes available. It’s a commitment to ongoing communication, not a one-time answer.

Grammatically, “keep someone posted” is a verb phrase built from the verb “keep,” an object (“you”), and the past participle “posted,” used as an adjective here. The structure follows the same pattern as “keep someone informed” or “keep someone updated.”

The phrase comes from the old practice of pinning notices to a post in a public square so people could stay informed. That’s also why “keep you post” — without the -ed — is grammatically incorrect. “Posted” is doing the job of an adjective, describing the state of being informed, so the ending can’t be dropped.

I see students drop that final “-ed” all the time in speech, and it slips into writing too. It’s a small error, but it’s noticeable to a native reader.

Why You Might Need an Alternative

You need an alternative to “I will keep you posted” whenever the phrase feels repetitive, too casual for the setting, or too vague to reassure the reader. Tone and specificity matter more than most writers realize.

A few common reasons to switch it up:

• You’ve already used it earlier in the same email thread.
• The setting is formal (legal, academic, executive communication).
• You want to sound more specific, like promising a deadline instead of a vague future update.
• You’re writing for a global audience where idioms like “posted” can confuse non-native readers.

Formal Alternatives

Formal alternatives to “I will keep you posted” work best in client emails, academic writing, legal correspondence, and messages to senior leadership. They sound precise and professional without losing warmth.

I Will Keep You Apprised

“Apprised” is a slightly formal verb meaning informed. This version is common in legal, financial, and corporate writing where precision matters.

Example: “I will keep you apprised of any changes to the shipping timeline.”

I Will Keep You Informed

This is the plainest, safest formal swap. It says exactly what it means with no idiom to interpret, which makes it a smart choice for non-native English speakers.

Example: “We will keep you informed as the investigation progresses.”

I Will Notify You As Soon As Possible

Use this when the update is a single, specific event rather than an ongoing stream of information — like a decision, an approval, or a result.

Example: “I will notify you as soon as the contract is signed.”

I Will Provide Regular Progress Updates

This phrase works well for long-term projects where the reader expects check-ins on a schedule, not just a one-off message.

Example: “I will provide regular progress updates throughout the renovation.”

I Will Update You Accordingly

“Accordingly” adds a sense of responsiveness — the update will match whatever happens next. It reads as measured and professional.

Example: “Once the board reviews the proposal, I will update you accordingly.”

Rest Assured, I Will Follow Up

This version reassures an anxious or high-stakes reader before promising the update itself. It’s useful in customer service and client-facing writing.

Example: “Rest assured, I will follow up the moment we hear back from the vendor.”

Professional and Workplace Alternatives

Professional alternatives sit between formal and casual — they’re the go-to phrases for coworkers, managers, and daily business communication. They sound confident without being stiff.

I’ll Keep You in the Loop

This is the most common professional substitute, and for good reason: it’s friendly, clear, and instantly understood in any English-speaking office.

Example: “I’ll keep you in the loop as we finalize the budget numbers.”

I’ll Touch Base With You

“Touch base” implies a brief, informal check-in rather than a detailed report. It’s ideal for quick status updates between colleagues.

Example: “I’ll touch base with you after the client call this afternoon.”

I’ll Circle Back With You

Popular in corporate settings, this phrase signals that you’ll return to a topic once you have more information, often after a meeting or a pending decision.

Example: “Let me circle back with you once I’ve confirmed the numbers with finance.”

I’ll Follow Up Once I Know More

Straightforward and honest. This works especially well when you genuinely don’t have a timeline yet and don’t want to overpromise.

Example: “I’ll follow up once I know more from the engineering team.”

I’ll Send You an Update by [Day or Time]

Instead of a vague promise, this version commits to a specific deadline. In my editing work, I always push clients toward this option — it builds more trust than an open-ended “I’ll keep you posted.”

Example: “I’ll send you an update by Thursday morning.”

I’ll Report Back With Findings

Use this when you’re actively researching or investigating something and plan to share results once you’re done.

Example: “I’ll report back with findings after I speak with the supplier.”

Informal and Casual Alternatives

Casual alternatives to “I will keep you posted” fit texts, group chats, and conversations with friends or close colleagues. They sound relaxed instead of scripted.

I’ll Let You Know

Simple, direct, and appropriate almost everywhere — including many professional contexts. It’s the safest casual option.

Example: “I’ll let you know as soon as I hear back.”

I’ll Fill You In

This phrase suggests you’ll give a fuller explanation later, not just a quick fact. It works well when there’s a story or backstory involved.

Example: “I’ll fill you in once I get out of this meeting.”

I’ll Give You the Scoop

Playful and conversational, this one is great for social contexts or workplace friendships. Skip it for clients or formal emails.

Example: “I’ll give you the scoop after the interview, I promise.”

I’ll Update You Later

Plain and easy, with no idiom to trip up non-native speakers, but still relaxed in tone.

Example: “I’ll update you later tonight once I’ve talked to my landlord.”

I’ll Give You a Heads-Up

This version implies advance warning, often before something happens rather than after. It’s common in scheduling and planning conversations.

Example: “I’ll give you a heads-up if the meeting time changes.”

I’ll Keep in Touch

A softer, broader promise of continued communication rather than a specific update. Best for personal relationships and ongoing contact.

Example: “I’ll keep in touch while I’m traveling for work.”

Common Mistakes to Avoid

The most common mistake with this phrase is writing “keep you post” instead of “keep you posted,” dropping the required past-participle ending. This changes the grammar of the sentence and reads as an error to native speakers.

Other mistakes I see often in student essays and business emails:

• Wrong preposition: “keep you posted for” instead of “keep you posted on” or “keep you posted about.”
• Mixed tenses: “I will kept you posted” — the modal “will” always takes the base form, so it should be “I will keep you posted.”
• Overuse in one message: repeating the exact phrase two or three times in a single email, which reads as lazy rather than reassuring.
• Treating it as a guarantee: using “I’ll keep you posted” without any real plan to follow up, which damages trust faster than saying nothing at all.

How to Choose the Right Alternative

Choose your alternative based on three things: your relationship with the reader, how formal the setting is, and whether you can commit to a specific timeline. A quick gut check before you hit send saves a lot of awkward tone mismatches.

Ask yourself:

• Is this a client, a boss, a coworker, or a friend?
• Does the situation call for precision (a deadline) or reassurance (ongoing contact)?
• Have I already used a similar phrase earlier in this conversation?

If you’re unsure, “I’ll keep you in the loop” or “I’ll let you know” are safe defaults that work in nearly any context.

We Will Keep You Updated Once We Receive an Update From the Team
