How to Write Professional Emails in English — Grammar Guide for Non-Native Speakers
Most email grammar mistakes aren't vocabulary problems. They're pattern problems — the same five or six structures that trip up non-native speakers every time.
I grew up speaking Hindi at home and learned English at school. By the time I was in college and writing emails to professors and internship managers, I thought my English was solid. Then someone — a professor I respect — gently pointed out that "please do the needful" isn't really standard English. Neither is "revert back at the earliest" or "please advice".
The thing is, these phrases feel completely natural if you've grown up reading them in Indian office communication. They're so common here that they seem correct. But the moment you're emailing a client in the US, UK, or Australia — they read as non-native immediately.
This guide is specifically about those patterns. The ones that are technically wrong but feel right. The fixes are simple once you know what to look for.

A 2022 survey found that 59% of hiring managers in English-speaking countries say grammar errors in emails reduce their confidence in a candidate. And that effect doesn't disappear once you're hired — it extends to client communication, internal reports, and anything written that builds (or damages) your professional reputation over time.
This isn't about being perfect. Native speakers make grammar mistakes too. It's about the specific patterns that create friction for the reader — that small moment where they pause and re-read your sentence because something felt off. Every one of those moments costs you a little credibility.
The good news: these patterns are learnable. And while you're learning them, a free grammar checker can catch most of them automatically.
The 5 Grammar Patterns That Undermine Professional Emails
1. Article Errors (a / an / the)
✗Please find attached report for your review.
✓Please find the attached report for your review.
Why: Specific, known items always need 'the'. The report you're attaching is specific — the reader knows which one.
✗I am looking for an feedback on this.
✓I am looking for feedback on this.
Why: Uncountable nouns (feedback, information, advice, help) don't take 'a' or 'an'. Ever.
2. Tense Problems
✗I am writing to inform that the meeting is scheduled and I send you the agenda.
✓I am writing to inform you that the meeting is scheduled and I have sent you the agenda.
Why: If the action is already done, use present perfect (have sent), not simple present (send).
✗Yesterday I try to call you but you are not available.
✓Yesterday I tried to call you but you were not available.
Why: 'Yesterday' is past time — both verbs must be past tense. This one slips through a lot.
3. Preposition Confusion
✗I am reaching out in regards of the project update.
✓I am reaching out regarding the project update.
Why: 'In regards of' is not standard English. Use 'regarding', 'about', or 'concerning' instead.
✗Please revert back on this at the earliest.
✓Please respond at your earliest convenience.
Why: 'Revert back' is redundant ('revert' already means go back). 'At the earliest' sounds abrupt — 'at your earliest convenience' is the professional form.
4. Subject-Verb Agreement
✗The team are looking forward to your response.
✓The team is looking forward to your response.
Why: In American and most international business English, collective nouns (team, company, management) take singular verbs.
✗Our findings shows that the project is on track.
✓Our findings show that the project is on track.
Why: 'Findings' is plural — it takes 'show', not 'shows'. Easy to miss when the subject feels far from the verb.
5. Confused Words
✗Please advice on the next steps.
✓Please advise on the next steps.
Why: 'Advice' is a noun. 'Advise' is the verb. 'Please advice' is extremely common in Indian business English and always wrong.
✗Their might be a delay in delivery.
✓There might be a delay in delivery.
Why: 'Their' = belonging to them. 'There' = location/existence. A grammar checker will always catch this one.

Grammar issues aside, here's the structure that works for 90% of professional English emails — especially when writing to someone in a Western business context:
Opening line
✓ Use this
I hope this email finds you well. / I wanted to follow up on...
✗ Avoid this
Kind Attention: / Respected Sir, / I am writing this email to you because...
Get to the point quickly. Long openers signal non-native writing immediately.
State your purpose
✓ Use this
I'm reaching out regarding... / I wanted to share... / Could you help with...
✗ Avoid this
I am writing this mail with reference to your esteemed company...
One clear sentence. What do you need and why?
Supporting detail
✓ Use this
I've attached the document. Please let me know if you have questions.
✗ Avoid this
Please do find the attached herewith for your kind perusal.
'Kind perusal', 'herewith', 'do the needful' — cut all of it.
Closing
✓ Use this
Thanks, / Best regards, / Looking forward to hearing from you.
✗ Avoid this
Thanking you in anticipation. / Please revert at the earliest.
'Revert' means to go back to a previous state — not to reply. Use 'respond' or 'reply'.

What are the most common grammar mistakes in professional English emails?
The most common grammar mistakes in professional emails are wrong articles (a/the/an), incorrect verb tense, missing subject, using 'kindly request' incorrectly, comma splices, and confused words like 'affect' vs 'effect' or 'your' vs 'you're'.
How can I check my email grammar before sending?
Use TaskGuru's free grammar checker — paste your email text, click Check, and fix any highlighted errors before hitting send. It takes under 30 seconds and requires no account.
Is it okay to use simple English in professional emails?
Absolutely. Clear, simple English is better than complex English with grammar errors. Native English speakers in business prefer direct, clean sentences over formal language that's hard to parse.
How do I improve my English email writing as a non-native speaker?
Write regularly, use a grammar checker for every important email, study real email templates from native speakers, and focus on mastering articles (a/an/the) and verb tenses first — these cause 70% of perceived grammar issues.
Should I use formal or informal English in work emails?
It depends on your company culture. In most modern workplaces — especially tech and startups — a semi-formal tone (professional but not stiff) is standard. With clients or senior stakeholders you don't know, lean slightly more formal until you understand the relationship.
Can I use a grammar checker for professional emails?
Yes — and you should. A grammar checker is particularly valuable for non-native English speakers before sending high-stakes emails. TaskGuru's free grammar checker checks spelling, grammar, punctuation, and style with no account required.
