How to Write a Professional Email in English
The structure and phrases that make an email sound polite and professional — openings, requests, and closings you can reuse immediately.
A professional email follows a predictable structure. Once you know the pattern and a handful of reusable phrases, writing one stops being stressful.
The structure
- Greeting
- Reason for writing
- The main request or information
- A polite closing
- Sign-off
0. The subject line
Before any of that: say what the email is about, and if there's an action, put it there.
- ✅ Invoice 4821 — payment query
- ✅ Friday's meeting — moved to 11:00
- 🚫 Question · 🚫 Hello · 🚫 Urgent!!
1. Greeting
- Dear Mr. Smith, (formal, when you know the name)
- Dear Sir or Madam, (formal, when you don't)
- Hi Sarah, (friendly but still professional, once you know someone)
2. Stating why you're writing
Get to the point quickly and politely.
- I'm writing to ask about...
- I'm reaching out regarding...
- I wanted to follow up on...
3. Making a polite request
Direct commands sound rude in English emails — soften requests with these patterns.
❌ Send me the report. ✅ Could you please send me the report? ✅ Would it be possible to get the report by Friday?
The longer the phrasing, the more polite it reads:
| Directness | Phrase |
|---|---|
| neutral | Could you send me…? |
| polite | Would you be able to send me…? |
| very polite | I was wondering whether you might be able to… |
| firm but civil | Could you send this by Thursday, please? I need it for the review. |
That last row matters: giving a reason for a deadline is what makes firmness acceptable rather than pushy.
4. Giving information clearly
- Please find attached...
- As discussed, here's...
- Just to confirm, the meeting is at 3 PM.
- For your reference, …
- To summarise: … — then use bullets. Long paragraphs in work email go unread.
5. Closing politely
- Please let me know if you have any questions.
- Looking forward to hearing from you.
- Thanks in advance for your help.
6. Sign-off
| Formality | Sign-off |
|---|---|
| Very formal | Yours sincerely, |
| Standard business | Best regards, |
| Slightly casual | Best, / Thanks, |
Chasing a reply
English chases gently the first time and specifically the second:
- Just following up on my email below.
- I wanted to check whether you'd had a chance to look at this.
- Sorry to chase, but I need an answer by Friday to keep this on track.
- Apologies if this has crossed with your reply.
Sorry to chase is the standard phrase, and it lets you be persistent without being rude.
Saying no by email
- Unfortunately, I won't be able to…
- I'm afraid that isn't something we can do.
- Much as I'd like to, I don't have the capacity this month.
- Would an alternative work — could we…?
Offering an alternative is what stops a refusal reading as a door closing.
Apologising by email
- Apologies for the delay in getting back to you.
- Sorry for the confusion — that was my mistake.
- Thank you for your patience. (better than apologising a third time)
One apology is professional; three in one email sounds anxious.
The mechanics people get wrong
- Reply all — only if everyone needs the answer. This is the most common workplace irritation.
- CC — for information, no action expected. BCC — hides recipients; use it for large lists, not for quietly copying someone in.
- Attachments — mention them in the text (Please find attached…), and attach the file before writing the email.
- Forwarding — check the thread below for anything the new reader shouldn't see.
Register is set by the first line and must hold to the last. Dear Ms Chen followed by cheers reads as careless, and so does a formal template sent to a colleague who writes in two-line replies. The safest rule: match the formality of the last email you received from that person.
Putting it all together
Dear Ms. Chen,
I'm writing to follow up on the proposal we discussed last week. Could you please confirm whether the budget has been approved?
Please let me know if you need anything else from my side.
Best regards,
Alex
And a week later, the follow-up:
Hi Ms. Chen,
Sorry to chase — just following up on the below. We'd need confirmation by Friday to start on schedule.
Happy to jump on a quick call if that's easier.
Best,
Alex
Same structure, shorter, with a reason for the deadline and an offer that makes saying yes easy.
