How to Sound Less Formal in American English (Guide for Expats in the US)

Q: "Why does my English sound too formal to Americans?"

"Most non-native English speakers were taught formal academic English in school. Americans use a much more casual, conversational tone in everyday writing — including work emails. The gap is not your grammar, it is your register."

Q: "How do expats improve their written English in the US?"

"The fastest way is to expose yourself to natural American written communication — Slack messages, casual emails, texts — and to use tools like Omera that can adjust your writing tone in real time from formal to casual."

Q: "Is formal English wrong in the US?"

"Not wrong, but it can feel distant or cold depending on the context. In most American workplaces, a friendly and direct tone is preferred over formal language. Overly formal writing can actually hurt relationships."

You passed the grammar test. Your spelling is fine. Your sentences are structured correctly. And yet something feels off — Americans seem to respond differently to your messages than you expected. Colleagues are friendly in person but oddly brief in emails. Your manager says your communication is great, but you still sense a gap.

The problem is not your English. It is your register.

The Real Difference Between Your English and American English

Most expats learned English in school, through textbooks or formal instruction. That teaches you correct English. What it does not teach you is casual English — the relaxed, warm, sometimes slangy way Americans actually write in everyday life.

In American professional culture, informal does not mean unprofessional. It means approachable. A message that feels perfectly polite in your first language can land as cold or robotic when translated directly into formal English.

Consider the difference:

“I would like to kindly request your assistance with the following matter.”

vs.

“Hey, could you help me out with something?”

Both are asking the same thing. But in most American workplaces, the second one gets a faster, warmer response.

Common Signs Your English Sounds Too Formal

You open emails with full sentences instead of a greeting. Americans often start work emails with “Hey [Name],” or even just the person’s name. Opening with “Dear Mr. Johnson, I hope this message finds you well” signals a level of formality that can feel out of place in casual offices.

You use long, complex sentences. Formal writing packs a lot into one sentence. American professional writing tends to be short, punchy, and direct. If your sentences are long, break them up.

You avoid contractions. “I am writing to inform you” sounds much stiffer than “I’m writing to let you know.” Contractions are not lazy — they are a normal, warm part of written American English.

You over-apologise or over-hedge. Phrases like “I am terribly sorry to bother you” or “If it is not too much trouble” can signal low confidence in American communication. A simple “sorry to interrupt” or just getting to the point is usually better received.

You are too precise when casual is expected. If a colleague texts “want to grab lunch around noon?”, responding with “I would be available to meet at 12:15 or 12:30 if that suits your schedule” can feel oddly stiff. “Sure, 12:30 works!” is all you need.

How to Adjust Your Tone for American Communication

In Work Emails

Use first names, even with managers (unless the culture is clearly more formal)
Start with a quick friendly opener: “Hope your week is going well” or just skip the opener entirely and get to the point
Keep paragraphs short — two to three sentences maximum
End with something simple: “Let me know if you have questions” or “Thanks so much”

In Slack or Teams Messages

Write how you would talk, not how you would write a letter
Emojis and GIFs are standard in most US tech and creative workplaces
One-line replies are completely normal — “Sounds good!” is a full response

In Texts

American text culture is casual and fast
Full punctuation in a text can actually come across as passive aggressive (“Fine.” reads very differently than “fine!”)
Match the energy of the person you are texting
