How to Write a Professional Email in English (With Templates)
· 9 min read · Breakers Academy
You reread it four times. You checked the grammar. You still hesitated before clicking send, because something about it felt slightly off — too stiff, or too blunt, or too long — and you could not say what.
That hesitation is rarely about grammar. Professional emails in English follow a fairly rigid shape, and most of the discomfort adults feel comes from writing a perfectly correct message in the wrong shape: the request buried in paragraph three, an opening borrowed from Spanish or Portuguese business letters, a subject line that says "Question" and tells the reader nothing.
The five-part structure every professional email follows
Every routine work email in English uses the same five blocks, in the same order. Learn the order once and you stop redesigning the message every time.
| Part | What it does | Example |
|---|---|---|
| Subject line | Says the topic and the action needed | "Invoice #4021 — approval needed by Fri" |
| Greeting | Sets the register | "Hi Daniel," / "Dear Ms. Alvarez," |
| Purpose line | States why you are writing, in one sentence | "I'm writing to confirm the delivery date for the March order." |
| Body | Details, context, or the request itself | 2–4 short sentences or bullets |
| Close + sign-off | Says what happens next, then ends | "Let me know if Thursday works. Best regards, Ana" |
The purpose line is the part most non-native writers skip, and it does the most work. English business readers scan before they read, and they decide early whether to act now, act later, or ignore. A message that opens with three sentences of context before revealing what you want gets filed under "later" and often never reopened.
Your subject line should name the topic and the action
Write the subject line last, and make it a summary rather than a label. "Question", "Follow up" and "Hello" are labels — they describe the category of email, not its content.
Inboxes cut the subject off sooner than you would expect — desktop clients somewhere around 50 to 70 characters, phone apps often closer to 35 — so put the important words first.
| Weak | Strong |
|---|---|
| "Question" | "Question about the Q3 travel budget" |
| "Following up" | "Following up: contract signature (due Thu)" |
| "Meeting" | "Move Tuesday's 10am to Wednesday?" |
| "Documents" | "Signed W-9 attached — anything else needed?" |
Two conventions worth copying: put a deadline in parentheses when one exists, and use a question mark when you genuinely need an answer. Both tell the reader, before they open anything, what kind of attention the message needs.
Greetings: use "Hi" more than you think
"Hi [First name]," is the default opening in US business English — for colleagues, for clients you have already spoken to, and for most external contacts after the first exchange. It is not casual. It is neutral.
| Greeting | Register | Use it when |
|---|---|---|
| "Hi Maria," | Standard professional | Colleagues, clients, anyone you've met |
| "Hello Maria," | Slightly more formal | First contact, or a serious topic |
| "Dear Ms. Alvarez," | Formal | Job applications, legal matters, senior strangers |
| "Hi all," / "Hi team," | Group, informal | Internal group emails |
| "Hello," | Neutral, no name | You have no name to use — a shared inbox, a form reply |
| "Good morning," | Warm, no name | Only when you know they will read it that morning |
Three openings to retire: "Dear Sir or Madam," (reads as a form letter and signals you did not look up a name), "Good day," (a direct translation from Russian and several other languages — it is not used in US English), and "Esteemed Mr. Silva," (a literal rendering of Estimado, which is standard in Spanish but sounds theatrical in English).
How to make a request without sounding rude
Ask as a question, with a modal verb and a date: "Could you send me the report by Wednesday?" That one move covers most requests in professional English. The common tone problem is not being too direct — it is translating politeness the long way around, because Spanish, Portuguese and Russian tend to build courtesy through formality and length, while English builds it through modals and softeners and then gets to the point.
| Instead of | Write | Why |
|---|---|---|
| "Send me the report." | "Could you send me the report by Wednesday?" | "Could you" is the standard polite request |
| "I need you to fix this." | "Would you be able to take another look at this?" | Softens without losing the ask |
| "I am writing you to inform you that..." | "Quick update on the Vasquez file:" | Shorter and more natural |
| "I remain at your disposal." | "Happy to help if anything else comes up." | The literal version sounds archaic |
| "You forgot to attach the file." | "I don't see the attachment — could you resend it?" | Removes blame from a small error |
| "I am still waiting for your answer." | "Just following up on this — any update?" | Neutral, not accusatory |
Notice where the extra words go. English spends them on the modal verb and the deadline — "Could you… by Wednesday?" — and cuts them from the ceremony around the request. The formal-sounding wrappers are the part to delete: "I am writing you to inform you that", "I remain at your disposal", "Please be advised". In English those read as distance or discomfort, not as respect.
Four templates you can copy
1. Making a request with a deadline
Subject: Contract review — need comments by Thu
Hi Daniel,
I'm sending over the vendor contract for your review. Could you send me your comments by Thursday? Legal needs the final version before the end of the month.
The two sections I'd especially like your view on are pricing (p. 3) and the termination clause (p. 7).
Thanks, Ana
2. Following up after no reply
Subject: Re: Contract review — need comments by Thu
Hi Daniel,
Following up on the message below. I need your comments by Thursday to keep our slot with Legal — even a quick "no objections" would be enough.
Let me know if it would be easier to talk this through for ten minutes instead.
Best regards, Ana
Reply inside the original thread so the previous message stays visible, wait three to five business days, and always give a reason for the timing. The reason is what keeps a follow-up from reading as impatience.
3. Saying no, or pushing back
Subject: Re: Friday workshop
Hi Priya,
Thanks for thinking of me for this. Unfortunately I won't be able to take it on this month — I'm at capacity with the migration until the 15th.
If it can wait until the following week, I'd be glad to help. Otherwise, Marcus knows this system well and might be a good alternative.
Best regards, Ana
The pattern is: thank, decline clearly, give a brief reason, offer an alternative. Skipping the clear decline — writing "I'll try to find some time" when you cannot — is the single most damaging habit here, because English readers take a soft maybe as a yes.
4. Apologizing for a delay or mistake
Subject: Corrected figures — March report
Hi Sofia,
Apologies for the delay, and thank you for your patience. The corrected March report is attached; the error was in the currency conversion on the second tab, and it's now fixed.
I've added a check step to the process so this doesn't repeat.
Best regards, Ana
Apologize once, in one sentence, then move immediately to the fix. Repeated apologies ("I am so terribly sorry, I really apologize, please forgive the inconvenience") read as anxiety in US business culture and tend to make the mistake look bigger than it is.
How to end a professional email
"Best regards," is the safe universal choice — formal enough for a stranger, warm enough for a colleague. Between people who work together daily, "Thanks," is the most common close in US offices.
| Sign-off | Register |
|---|---|
| "Best regards," | Universal, safe anywhere |
| "Thanks," / "Thank you," | Standard between colleagues |
| "Best," | Slightly informal, very common |
| "Sincerely," | Formal — cover letters, official letters |
| "Talk soon," | Friendly, only with people you know |
Before the sign-off, add one sentence saying what happens next: "I'll send the revised version Monday," or "Let me know if Thursday works." An email that ends without a next step puts the burden of deciding on the reader, which is the most common reason a reply never comes.
The six-point check before you hit send
Run this in under a minute:
- Can the reader tell what you want from the first two lines? If not, move the ask up.
- Does the subject line name the topic and the action?
- Is there a deadline, and is it a real date? "ASAP" means nothing; "by Thursday at noon" does.
- Did you attach the attachment? Search your own draft for the word "attached" before sending.
- Is the name spelled correctly? This one costs more goodwill than any grammar error in the message.
- Would you be comfortable if this were forwarded? Work email is never private.
Where email fits in the bigger picture
Email is the part of professional English you can control completely: you draft, check and rewrite before anyone sees it. That makes it the best place to build a stock of phrases — and the phrases in a request email are the same ones you need in a meeting, where there is no time to plan them.
Building that stock deliberately is most of what Business English practice is for: pushing back, asking for clarification, chasing a decision, delivering bad news — rehearsed until they arrive without effort. Teams that need the same thing across a whole department can build it together through corporate English training.

Frequently asked questions
How long should a professional email be?
Aim for 50 to 150 words for a routine work email. If your message is longer than about 200 words, put the request in the first two lines and move the background into bullet points below it. Anything that needs more than a screen is usually a call or a document, not an email.
Is it rude to start an email with 'Hi' instead of 'Dear'?
No. In US business English, 'Hi [First name],' is the standard opening for colleagues, clients you have already spoken to, and most external contacts. 'Dear Ms. Alvarez,' is reserved for first contact with someone senior or unknown, job applications, and formal or legal correspondence.
How do I follow up without sounding pushy?
Wait three to five business days, reply in the same thread, and give a reason for the timing rather than expressing frustration. 'Following up on the message below — I need an answer by Thursday to keep the vendor slot' is direct and neutral. Avoid 'as I already mentioned' and 'I am still waiting'.
Should I use contractions like 'I'm' and 'we'll' in a work email?
Yes, in most US workplaces. Contractions read as natural and confident rather than casual. Write them out in full ('I am', 'we will') only in formal contexts such as a legal notice, a complaint, or a first email to a senior executive you have never met.
What is the safest way to end a professional email in English?
'Best regards,' works in every situation from formal to friendly. 'Thanks,' is the most common sign-off between colleagues. Avoid direct translations such as 'Attentively' or 'I remain at your disposal' — they are grammatically correct but sound archaic to a US reader.
The one habit worth building
Keep a personal file of emails that worked. When a colleague writes something you would not have thought to write — a clean decline, a follow-up that got an instant answer, a graceful way of saying "this is wrong" — save it and reuse the pattern. Native speakers are not inventing these sentences either; they are reusing a small stock of shapes absorbed from other people's inboxes. The only difference is that you can build the same collection on purpose.
