You can hold a conversation in English, but the moment you open a blank email to a manager, a landlord, or a university admissions office, everything freezes. What do you write after “Hello”? Is “Dear Sir” too stiff? Should you apologise for writing at all?
Email is one of the highest-stakes forms of written English because it leaves a record. A clumsy sentence in conversation disappears; a clumsy sentence in an email sits in someone’s inbox for years. The good news is that English emails are formulaic. Once you learn the skeleton and a handful of reliable phrases, you can write almost any message in five minutes.
The Anatomy of an English Email
Nearly every professional email in English follows the same six-part structure. Learn the parts, and you never face a blank page again.
- Subject line — what the email is about, in 3–8 words.
- Greeting — how you address the reader.
- Opening line — a short bridge before your point.
- Body — your actual message, ideally under four short paragraphs.
- Call to action — what you want the reader to do next.
- Sign-off and signature — your closing phrase and name.
Subject lines: be specific, not polite
Learners often write vague subject lines like “Question” or “Hello from Maria.” Native professionals write subject lines that describe content so the reader can triage the inbox at a glance.
- ❌ “Important” → ✅ “Invoice #4417 — payment due 30 March”
- ❌ “Meeting” → ✅ “Can we move Thursday’s call to 3pm?”
- ❌ “Job” → ✅ “Application: Junior Data Analyst (ref. DA-22)”
If your email needs no reply, say so: “FYI — no action needed.” If it is urgent, put the deadline in the subject rather than shouting in capitals. All caps reads as anger in English.
Greetings: Choosing the Right Register
English has fewer formality levels than Spanish, French, or Japanese, but the levels it does have matter. The table below maps common greetings to the situations they suit.
| Greeting | Formality | Use when |
|---|---|---|
| Dear Sir or Madam, | Very formal | You have no name at all — legal, official, or institutional letters |
| Dear Dr Okafor, | Formal | First contact with a professor, doctor, or senior professional |
| Dear Ms Patel, | Formal | Job applications, formal complaints, unknown recipients |
| Hello Amina, | Neutral | Most workplace email — safe in almost any context |
| Hi Tom, | Friendly neutral | Colleagues, clients you know, ongoing threads |
| Hey, | Informal | Close colleagues and friends only |
| Morning all, | Informal group | Internal team messages, mostly British English |
Three practical rules save you from most errors. First, “Dear Sir or Madam” is now a last resort — spend two minutes on LinkedIn or the company website to find a name. Second, never guess marital status: use “Ms” rather than “Mrs” or “Miss” unless the person uses another title themselves. Third, mirror the other person. If they open with “Hi Sofia” and sign “Best, Dan,” you can safely reply “Hi Dan.”
One frequent transfer error: many languages allow “Dear Mr John” using a first name. English does not. It is “Dear Mr Smith” (surname) or “Dear John” (first name), never a mix.
Opening Lines That Don’t Sound Translated
Learners often start with a literal translation such as “I am writing you for asking about…” A few natural openers will cover nearly every situation:
- Purpose: “I’m writing to ask about the delivery date for order #338.”
- Follow-up: “Following up on my message from Tuesday…”
- Reference: “Thanks for your email about the workshop.”
- Warm neutral: “I hope you’re well.” (Safe, if slightly formulaic.)
- Reconnecting: “It was great to meet you at the conference in Lisbon.”
Skip the long apology. Writing “I am sorry to disturb you with my small problem” sounds anxious in English. State your purpose in the first two lines — English business writing rewards directness.
Formal vs. Informal: A Side-by-Side Comparison
The clearest way to feel the difference in register is to see the same idea written twice.
| Function | Formal | Informal |
|---|---|---|
| Requesting | I would be grateful if you could send the report. | Could you send the report? |
| Apologising | Please accept my apologies for the delay. | Sorry for the slow reply! |
| Attaching | Please find the invoice attached. | I’ve attached the invoice. |
| Asking for info | I would appreciate any clarification you can provide. | Can you let me know? |
| Declining | Unfortunately, I am unable to attend. | Sorry, I can’t make it. |
| Closing | I look forward to hearing from you. | Let me know what you think! |
| Sign-off | Yours sincerely / Kind regards | Best / Cheers / Thanks |
Notice the grammar patterns behind the register. Formal English favours modal verbs (“would,” “could”), the passive voice (“Please find attached”), and Latin-derived vocabulary (“request,” “clarification,” “unable”). Informal English uses contractions (“I’ve,” “can’t”), phrasal verbs (“get back to me,” “set up a call”), and shorter Anglo-Saxon words.
A note on sign-offs
British convention traditionally pairs “Yours sincerely” with a named recipient and “Yours faithfully” with “Dear Sir or Madam.” American English mostly uses “Sincerely” for both. In practice, “Kind regards” and “Best regards” are the safest all-purpose sign-offs in international English. Avoid “Cheers” with people you have never met, and avoid “Yours truly” unless you want to sound like a nineteenth-century novel.
Three Templates You Can Adapt Today
1. Asking a professor or manager for an extension
Subject: Extension request — Module 4 essay (deadline 12 May)
Dear Dr Lang,
I’m writing to ask whether it would be possible to extend the deadline for the Module 4 essay by three days. I have been unwell this week and have a medical note if you need it. I would be able to submit by Friday 15 May at the latest. Thank you for considering this, and please let me know if you need anything further.
Kind regards,
Lucía Fernández
2. Replying to a job advertisement
Subject: Application — Marketing Assistant (ref. MA-104)
Dear Ms Adeyemi,
I’m applying for the Marketing Assistant position advertised on your careers page. I have three years’ experience managing social campaigns for a mid-sized retailer, where I grew organic engagement by 40%. My CV is attached, and I would welcome the chance to discuss how my experience fits your team. Thank you for your time.
Yours sincerely,
Karim Haddad
3. A quick informal work message
Subject: Moving tomorrow’s call?
Hi Sam,
Any chance we could push tomorrow’s call to 3pm? Something’s come up in the morning. Happy to work around you if that doesn’t suit.
Thanks,
Ana
Mistakes That Instantly Signal a Non-Native Writer
- “I am writing you” → write “I am writing to you” or simply “I’m writing to ask…”
- “Please, could you…” → the comma after “please” is a common transfer error; write “Please could you…”
- “I wait your answer” → “I look forward to hearing from you.”
- “Thanks in advance” → widely used, but it can feel presumptuous. “Thank you for your help” is safer.
- Over-formality — “Esteemed Sir, I humbly request…” reads as strange rather than respectful.
- Wall of text — English readers scan. Break your message into paragraphs of two or three sentences, and use bullets for lists.
- Missing call to action — always finish by saying what you want: a reply, a decision, a date.
Frequently Asked Questions
Is it rude to write a very short email in English?
No — brevity is usually seen as respectful of the reader’s time, particularly in American and British workplaces. A three-line email with a clear request is far more effective than a page of polite framing. Just keep the greeting and sign-off in place; those are what carry the courtesy.
How long should I wait before sending a follow-up?
Three to five working days is the standard window for a business email. Keep the follow-up light and blame the inbox rather than the person: “Just floating this back to the top of your inbox — no rush if you’re busy.” Two unanswered follow-ups usually means the answer is no.
Should I use British or American English?
Match your reader. If you’re writing to a London company, “organise,” “apologise,” and “Yours faithfully” fit naturally; for a US recipient, use “organize,” “apologize,” and “Sincerely.” What matters most is consistency — don’t mix spellings within one message.
Can I use emojis and exclamation marks?
In informal messages to colleagues you know, one exclamation mark or a friendly emoji is fine and increasingly common. In formal contexts — job applications, complaints, first contact with an institution — leave them out entirely. When in doubt, write the plain version.
Writing confident emails in English is a skill you build through feedback, not memorisation. If you’d like someone to read your drafts, explain why a phrase sounds too stiff or too casual, and rehearse the situations you actually face at work or university, book a session with a tutor at The Cognitio — we’ll help you write emails that get answered.
