We will inform you

You generally use this phrase when there is a delay between a process and its result. Think of it as a bridge. You’ve done the interview, or you’ve sent the support ticket, and now you’re in the "waiting room" of life. To use it correctly, you often pair it with a specific topic using the word of. For example: We will inform you of our decision. You can also use it with a time frame to make it feel less like you're being "ghosted" by a corporation. Adding by Friday or as soon as possible makes the phrase feel a lot warmer. It’s like putting a nice rug in an office; it softens the hard edges of the business talk. Just remember, it usually requires an object (the person being informed) and the information being shared. If you just say We will inform, people will look at you like you forgot the rest of your sentence!

This phrase lives in the land of blazers, spreadsheets, and LinkedIn posts. It is strictly formal or high-neutral. You would never use this while playing a video game with friends or ordering a late-night kebab. If you told your best friend, I will inform you of my arrival at the pub, they would probably check if you’d been replaced by an AI bot. It is designed for situations where there is a professional distance. It’s perfect for customer service bots, HR departments, and government officials. However, in the modern world of Slack and WhatsApp, even businesses are moving toward I’ll let you know, which is the casual cousin of we will inform you. Think of inform as the expensive champagne and let you know as the reliable craft beer. Both get the job done, but one is much fancier.

You’ll see this everywhere once you start looking. When you sign up for a beta test of a new app, the confirmation screen might say, We will inform you when your account is ready. If a flight is delayed, the overhead speakers might crackle with, We will inform you of the new boarding time shortly. Even in the world of Netflix or Disney+, if a show you want to watch isn't out yet, you might get a notification saying they will inform you upon its release. It’s the standard language of the "Wait and See" club. It shows up in legal letters, university acceptance emails (the scary ones!), and even in those automated "out of office" replies that we all love to send before a holiday. It’s the ultimate "to-be-continued" cliffhanger of the professional world.

Use this phrase when you want to sound like a professional who has everything under control. It is great for job interviewers who want to be polite but firm about the timeline. It’s also perfect for customer support agents who need to investigate a bug. If a user complains that their app is crashing, saying We will inform you once the fix is deployed sounds much more competent than We’ll tell you when it’s fixed. It builds trust. Use it when you are speaking on behalf of a group or a company—the we gives it a collective authority. It’s also useful when you want to stop someone from calling you every five minutes. It’s a polite way of saying, "Don't call us, we'll call you."

Avoid this phrase in any situation that requires warmth, intimacy, or immediate action. If your partner asks what time you’ll be home for dinner, saying I will inform you of my ETA is a great way to end up eating dinner alone on the sofa. It is also too heavy for small, trivial updates. You don't need to "inform" someone that you've finished a cup of coffee. Furthermore, don't use it if you are actually talking to just one person and want to sound friendly; I’ll let you know is much better for building a personal connection. Using inform can sometimes make you sound like a bureaucrat from a 1950s movie, so use it sparingly if you want to be seen as a modern, approachable human being.

The most classic error is adding an extra word where it doesn't belong. Many people try to say ✗ We will inform to you. In English, you inform *someone*, you don't inform *to* someone. It’s a direct action! Another mistake is forgetting the subject matter. ✗ We will inform you tomorrow is okay, but it's much better to say ✓ We will inform you of the status tomorrow. Also, watch out for the "robot effect." If you use this phrase five times in one email, you’ll sound like an automated spam filter. Mix it up! Don't be the person who writes like a legal contract when you're just trying to schedule a quick meeting. English is flexible—don't let your formal phrases turn into a straightjacket.

If we will inform you feels a bit too stiff, you have options. The most common is We’ll let you know. This is the bread and butter of casual business English. For something a bit more "tech-savvy" or modern, you might hear We’ll keep you posted or We’ll keep you in the loop. These variations imply a continuous flow of information rather than just one final update. In very formal British English, you might even hear We shall keep you advised, which is basically the "monocle and top hat" version of the phrase. If you’re texting a friend, just use I'll hit you up (very slangy) or I’ll message you. Each variation changes the "vibe" while keeping the meaning the same.

Does this phrase mean I got the job? Not necessarily. It just means they will tell you the result, whether it's a "yes" or a "no." It’s a promise of communication, not a promise of success. Is shall better than will? In the 1800s, maybe! Today, will is the standard. Using shall makes you sound like a character in a period drama. Can I use it in a text message? Only if you are being funny or if you are talking to a client you’ve never met. Otherwise, it’s a bit too formal for a thumb-typed message. What if I forget to inform them? Then you’ve broken a professional promise! This phrase creates an expectation, so make sure you actually follow up. It’s better to say nothing than to promise an update you can't deliver.
