A formal email has five parts: a clear subject line, a polite greeting, a short body that states your purpose, a courteous closing, and your name and signature. The goal is to be clear and respectful in as few words as possible. Whether you're applying for a job, asking for leave, or making an enquiry, the same simple structure works every time.
The five parts of a formal email
- Subject line — a short summary of what the email is about.
- Greeting — "Dear Sir/Madam," or "Dear Mr Sharma,".
- Body — 2 to 4 short paragraphs stating your purpose and details.
- Closing — "Regards," or "Yours sincerely,".
- Signature — your full name, and phone number if useful.
Write a strong subject line
The subject tells the reader what to expect. Keep it specific:
- Good: "Application for Data Entry Operator Position"
- Good: "Leave Request for 22–23 July"
- Weak: "Hi" or "Important" (too vague)
Keep the body clear
- Open with your purpose in the first line: "I am writing to apply for…".
- Give the needed details in short paragraphs.
- End with what you want to happen: "I have attached my resume for your review."
Avoid slang, emojis and long rambling paragraphs. One idea per paragraph.

- Read it once before sending. A quick check catches most mistakes.
Common mistakes
- A vague or missing subject. The reader may ignore or miss it. Always add a clear subject.
- Too casual. Slang and emojis look unprofessional in a work or job email.
