Writing emails in English requires more than correct grammar. Choosing the right tone, structure, and expressions is essential, especially when writing to colleagues, clients, or business partners. This guide explains how to write clear, polite, and appropriate emails in English by separating formal and informal language and following standard email etiquette.
How to Write an Email in English
Subject Line
The subject line tells the reader why you are writing. A clear subject line makes your email look professional and prevents it from being ignored or treated as spam.
- Meeting Request for Monday
- Question About the Project Timeline
- Thank You for the Interview
- Follow-up on Our Last Discussion
Opening (Greeting)
Choose your greeting based on how formal your relationship is with the reader.
Formal Openings
- Dear Mr Smith,
- Dear Ms Johnson,
- Dear Dr Brown,
- Dear Sir or Madam,
Note: When using titles such as Mr, Ms, or Dr, always follow them with a surname, not a first name (e.g. Dear Mr Smith, not Dear Mr John). This style is consistent with UK English. In US English, a period is often used (Mr. Smith), but consistency is more important than the variant you choose.
Informal Openings
- Hi Alex,
- Hello Michael,
- Dear Sam,
- My dear father,
Friendly Follow-up Questions (Informal Only)
- How are you?
- How’s life?
- How are things?
- What are you up to these days?
Note: Very informal phrases such as “Anything strange?” should only be used with close friends and should never appear in professional or business emails.
Punctuation tip: Always place a comma after your greeting (e.g. Dear Mr Smith,).
Reason for Writing (Email Body – Introduction)
After the greeting, clearly state why you are writing. This helps the reader understand your purpose immediately.
Formal Expressions
- I am writing to ask about…
- I am writing to inform you that…
- I am writing in connection with…
- I would like to inquire about…
Informal Expressions
- I’m just writing to let you know…
- I wanted to ask you about…
- Just a quick message to say…
Expressing Thanks
| Formal | Informal |
|---|---|
| Thank you very much for… | Thanks a lot for… |
| I sincerely appreciate your help. | Thanks a million for… |
| Thank you for your time and consideration. | I really appreciate it. |
| — | Cheers for… |
Note: “Cheers for…” is very informal and should not be used in professional or business contexts.
Giving News
| Good News | Bad News |
|---|---|
| I’m pleased to inform you that… | Unfortunately, I have some bad news. |
| I’m happy to let you know that… | I’m afraid I have some bad news. |
| Great news — I’ve… | We regret to inform you that… |
Call to Action (Pre-closing)
A complete email usually includes a short line that invites a response or action.
Formal
- I look forward to hearing from you.
- Please let me know if you require any further information.
Informal
- Let me know what you think.
- Hope to hear from you soon.
Closing (Ending the Email)
| Formal Closings | Informal Closings |
|---|---|
| Kind regards, | All the best, |
| Best regards, | Take care, |
| Sincerely, | See you soon, |
| Yours faithfully, | All my love, |
Note: “All my love” should only be used for family members or very close personal relationships.
Punctuation tip: Always place a comma after your closing (e.g. Best regards,).
