How to Write a Professional Email in English (with Templates)

Email is still the main way people communicate at work, at university and with clients. A clear, polite email in English can help you get a job, solve a problem quickly or build a good relationship with your manager. A confusing one can create misunderstandings and make you look less professional, even if your idea is excellent.

The good news is that professional emails follow a simple, repeatable pattern. In this guide, you will learn the 6-part structure of a professional email, useful phrases for each part, ready-to-use templates, and the mistakes many learners around the world make.

The 6 Parts of a Professional Email

1. Subject line

The subject line tells the reader what the email is about before they open it. Keep it short and specific.

• Weak: "Request"

• Better: "Leave request for 12–14 November"

• Better: "Question about Invoice #2045"

2. Greeting

Use the person's name whenever you know it.

• Formal: "Dear Mr. Patel," / "Dear Ms. Garcia,"

• Neutral: "Hello Priya,"

• Name unknown: "Dear Hiring Manager," or "Dear Customer Support Team,"

Avoid "Dear Sir" if you are not sure who will read the email. It sounds outdated to many modern readers.

3. Opening line and purpose

Get to the point in the first one or two sentences. Busy readers want to know why you are writing.

• "I am writing to ask about..."

• "I'm writing to follow up on our meeting yesterday."

• "Thank you for your quick reply."

4. Body

Give the important details in short paragraphs of two to four sentences. If you have several points, use a numbered list so the reader can answer each one.

5. Request or next step

Tell the reader exactly what you need and, if possible, by when.

• "Could you please send the report by Thursday?"

• "Please let me know if Tuesday at 3 pm works for you."

6. Closing and signature

• Formal: "Kind regards," / "Best regards,"

• Friendly but professional: "Thanks," / "Many thanks,"

Add your full name, job title and phone number below the closing.

Useful Phrases for Professional Emails

• Asking politely: "Would it be possible to...?" / "I would appreciate it if you could..."

• Attaching files: "Please find the report attached."

• Following up: "I just wanted to follow up on my previous email."

• Apologising: "I apologise for the delay in replying."

• Ending: "Please let me know if you have any questions."

Common Email Mistakes to Avoid

• Old-fashioned phrases: "I beg to inform you" or "Kindly do the needful" sound outdated. Use simple, direct English.

• Writing everything in one paragraph: Long blocks of text are hard to read.

• All capital letters: WRITING IN CAPITALS feels like shouting.

• Too informal: Avoid "Hey bro", emojis and SMS spelling like "plz" or "u".

• Forgetting the attachment: Attach the file before you write the email.

• Not proofreading: Read your email once before sending. Our guide to common grammar mistakes English learners make can help.

Frequently Asked Questions

How long should a professional email be?

Most professional emails should be 50–150 words. If you need more, use short paragraphs or a list.

Is "Dear Sir/Madam" still acceptable?

It is acceptable in very formal letters, but "Dear Hiring Manager" or the person's name is more modern and usually better.

Should I write "Thanks" or "Best regards"?

"Best regards" is safe for almost every situation. "Thanks" works well when you are asking for help or with colleagues you know.

How quickly should I reply to a work email?

Try to reply within 24 hours on working days. If you need more time, send a short reply saying when you will respond fully.
