How to Write a Formal Email (Structure + 5 Templates)

How to Write a Formal Email (Structure + 5 Worked Templates)

To write a formal email, use a clear subject line; open with a title-and-surname greeting (‘Dear Ms. Lim,’); state your purpose in the first sentence; keep the body to three short paragraphs covering context, the request, and the next step; close with ‘Yours sincerely,’ or ‘Kind regards,’; and finish with a full signature block (name, role, organisation, contact). Proofread before you send. If you do not know the recipient’s name, use the most specific role-based greeting you have, like ‘Dear Hiring Manager,’ or ‘Dear Admissions Office,’.

I have been training working professionals in Singapore for 24 years, and the one workplace skill that quietly decides who gets the meeting, the interview, or the refund is the formal email. A well-written one opens doors. A sloppy one gets archived. In this guide on how to write a formal email I will walk you through the full structure, then five copy-paste templates for the situations my Writing Professional Emails workshop participants ask about most often: job applications, emails to a professor or university, complaints, sending with an attachment, and a short reference for Spanish and German. I will also cover the part most online guides skip — what to do when you do not know the recipient’s name, and the six small mistakes that show up in formal emails written by professionals whose first language is not English. Do try it out on a real email this week. The fastest way to improve is to write one well, send it, and see who replies.

Formal vs professional vs business email: which one are you actually writing?

These three terms get used interchangeably, and most online guides do not bother to separate them. They are different in a way that changes how you write.

A formal email is the strictest of the three. It follows a fixed structure: clear subject line, full title-and-surname greeting, body free of contractions and slang, polished sign-off, complete signature. You use it when the relationship is new, the stakes are high, or the context is official. A job application. A complaint. A cover letter for a tender. An enquiry to a university. A letter to a government office.

A professional email is any work email you send in a respectful tone. It is less strict. Once you have replied to a client a few times, a professional email is shorter, uses first names (‘Hi Sarah,’), allows contractions, and may skip the formal sign-off (‘Best,’ instead of ‘Yours sincerely,’). Most of the email you write at work is professional, not formal. We cover the full taxonomy in our companion guide on how to write a professional email.

A business email sits somewhere in the middle, and is usually defined by content rather than tone. It is any email about a commercial transaction — a quotation, an invoice, an order confirmation, a follow-up after a meeting. The tone can be formal or relaxed, depending on the relationship.

A short way to think about it: a formal email is like wearing a full suit to the meeting. A professional email is the smart-casual you wear once you know the room. A business email is whatever the deal calls for. Most people in Singapore offices over-dress on email when they do not need to, and under-dress when they really should. Knowing which one the situation needs is half the skill.

Here is the quick comparison.

Type	When to use	Greeting	Sign-off	Tone
Formal	First contact, official, high-stakes	Dear Mr./Ms. Surname	Yours sincerely / Kind regards	No contractions, no slang
Professional	Day-to-day work	Hi First-Name or Dear First-Name	Best regards / Best / Thanks	Polite, contractions OK
Business	Commercial transactions	Either of the above	Either of the above	Whatever the relationship calls for

The rest of this guide focuses on the formal end of the scale. If you have decided the message you are writing is closer to professional or business, drop the strictest conventions, but keep the structure. The structure is what makes the message easy to read.

The anatomy of a formal email (subject, greeting, body, closing, signature)

Every well-written formal email is built from the same five parts. Get the parts right and the message reads as polished even before the recipient processes what you have said. Think of it like a building. Foundation, walls, roof, doors, windows. Skip the foundation and the rest wobbles.

1. Subject line. Five to nine words. State the request and a date or reference if there is one. “Application: Senior Marketing Manager — Jasmine Tan” beats “Job application”. “Vacation request: 10–20 August” beats “Leave”. Vague subjects like “Quick question” or “Hello” get skimmed past. Your boss has 200 emails a day. Make it easy.
2. Greeting. Use the recipient’s title and surname when you know it (“Dear Ms. Lim,”, “Dear Dr. Rao,”, “Dear Professor Tan,”). If you only know the role, use the role (“Dear Hiring Manager,”). The comma at the end is non-negotiable in formal writing. “Hi” is fine in a professional email, not in a strict formal one.
3. Opening sentence. State your purpose in the first line. Do not open with “I hope this email finds you well” — that is professional padding, not formal substance. Open with “I am writing to apply for the Senior Designer role advertised on your careers page on 12 May.” Or “I am writing to request an extension to the project deadline currently set for 30 May.” Get to the point.
4. Body. Two or three short paragraphs. Paragraph 1: context — who you are, why you are writing. Paragraph 2: the substance — the request, the question, the issue. Paragraph 3: the next step — what you want the reader to do, and by when. Keep paragraphs to four or five sentences each. Avoid contractions (‘do not’ rather than ‘don’t’), avoid slang, and avoid emoji.
5. Closing and signature. A short closing line (“I look forward to your reply.” or “Thank you for considering this request.”), then a sign-off (“Yours sincerely,” if you used the recipient’s name; “Yours faithfully,” if you opened with “Dear Sir or Madam,”; “Kind regards,” for slightly less stiff formal contexts). After the sign-off, a full signature: your full name, your job title and organisation, your phone number, your email address, and your LinkedIn profile or website if it is relevant.

Get these five parts right and the rest of the email is decoration. A formal email failing on the structure is much harder to recover than one with a slightly wobbly turn of phrase in paragraph two.

How to start a formal email when you don’t know the recipient’s name

The “Dear Sir or Madam,” versus “To Whom It May Concern,” debate is the part of formal-email writing that every online guide mentions in passing and none of them actually answers. After reading thousands of student drafts in my workshops, I can tell you the choice is not random. Use this decision tree.

Step 1 — Look for the name first. Before defaulting to a generic greeting, spend two minutes on LinkedIn or the company’s website. The hiring manager, the head of admissions, the customer-service lead — they are usually findable. A formal email addressed to a real person by name gets opened more reliably than one addressed to nobody. How good is that for two minutes of work?

Step 2 — If you cannot find the name, use the role. “Dear Hiring Manager,” for a job application. “Dear Admissions Officer,” for a university enquiry. “Dear Customer Service Manager,” for a complaint. “Dear Editor,” for a letter to a publication. “Dear Selection Committee,” for a grant or scholarship application. The role-based greeting is more specific than a generic salutation and reads as respectful research.

Step 3 — If you do not know the role, use the team. “Dear Customer Support Team,” “Dear HR Team,” “Dear Admissions Office,” “Dear Recruitment Team,”. You are showing you have thought about who at the other end is likely to receive this.

Step 4 — Only if none of the above is possible, use a true generic. “Dear Sir or Madam,” is still acceptable in the most formal contexts (legal correspondence, government, official complaints, cover letters where the role is unknown). Pair it with “Yours faithfully,” as the sign-off. That pairing is a strict UK-English convention and still expected in formal British and Commonwealth writing — including in Singapore, where MOM letters, university transcripts, and bank correspondence still follow it. “To Whom It May Concern,” is appropriate when the email may genuinely be passed between several people: references, complaints to a regulator, open letters.

A few greetings to avoid in a strict formal email: “Hi there,” (too casual), “Hello,” on its own (it reads as mass-mail), “Hey,” (never), “Greetings,” (dated), “Good morning,” as a salutation (it is a phrase, not a greeting — the email may be opened in the afternoon).

When the email is going out to a group, “Dear all,” or “Dear Team,” is fine. “Dear colleagues,” is fine within an organisation. Do not combine greetings. “Dear Sir or Madam / To Whom It May Concern” is amateur.

Worked template 1 — formal email for a job application

The job-application email is the formal-email use case most people get wrong by trying too hard. The trap is over-decorated language (“I would be most honoured to be considered…”) that reads as desperate. The template below is short, factual, and confident. Confidence on the page is a muscle, not a personality trait — people who appear confident on email have rehearsed.

Subject: Application: Senior Marketing Manager — Jasmine Tan

Dear Hiring Manager,

I am writing to apply for the Senior Marketing Manager position advertised on your careers page on 12 May 2026. I have eight years of B2B marketing experience in the SaaS sector, most recently as Marketing Lead at Northwind Pte Ltd in Singapore, where I grew inbound leads by 64% year-on-year.

I am attaching my CV and a one-page summary of three campaigns I have led from concept to launch. The achievements that map most directly to the role description are the demand-generation programme I built at Northwind (S$2.3m in pipeline in twelve months) and the partner-marketing function I set up at my previous role.

I would welcome the opportunity to discuss how my experience fits the role. I am available for an interview at your convenience and can be reached at +65 9123 4567 or jasmine.tan@example.com.

Yours sincerely,
Jasmine Tan

A few notes on what is doing the work in this template. The subject line names the role and the candidate. A hiring manager scanning fifty applications can sort by candidate name without opening anything. The greeting uses the role (“Dear Hiring Manager,”) because the actual name almost never appears in a job advert. If you do find the recruiter’s name on LinkedIn, use it. The first sentence states what the email is about. The second sentence gives one concrete result (“64%” growth). Never write “I am a strong communicator”. The closing sentence offers a specific next step (interview), and the signature includes a phone number so the recruiter can call without going hunting for it. The template fits comfortably under 180 words. If the hiring manager does not reply within five working days, see our guide on how to write a follow-up email that nudges politely without nagging.

Worked template 2 — formal email to a professor or university

Two variants in one section, because the underlying structure is almost identical.

Variant A — Email to a professor (request a meeting, ask a question, ask for feedback).

Subject: ECON3203 — Request for office-hour appointment, week of 27 May

Dear Professor Tan,

I am Wei Ming Ng, a student in your ECON3203 Macroeconomic Policy class this semester (Tuesday 10am tutorial, Group B). I am writing to ask whether I could book a 15-minute slot in your office hours during the week of 27 May to discuss the literature review section of my term paper on Singapore's housing-supply elasticity.

I have already drafted the section and would like your feedback on the choice of empirical sources and the framing of the comparison with the Hong Kong literature. I am free on Tuesday and Thursday afternoon, but I can adjust to whichever time suits you best.

Thank you for your time and for the helpful direction in last week's seminar.

Yours sincerely,
Ng Wei Ming
Matric No. A0234567B
ECON3203, Group B
e0234567@u.nus.edu

Variant B — Email to a university admissions office.

The opening sentence states the programme you are enquiring about. The body asks two or three specific questions (never “tell me everything about the programme”). The sign-off uses “Yours faithfully,” if you addressed the email to “Dear Admissions Office,” and “Yours sincerely,” if you found the admissions officer’s name. Always send the email from your school or personal email — never from a flippant or shared address.

A note on tone. Professors and admissions staff read hundreds of emails a week. Specificity is respect. Naming the course code, the tutorial group, the matric number, and the date you are referring to lets the reader place you in three seconds. A vague email (“Hello Professor, I have a question about the assignment, please can we meet”) gets pushed to the bottom of the pile. Of course it does.

Worked template 3 — formal email of complaint

The formal email of complaint is firm, factual, and specific. Anger is fine in your head; on the page, anger sounds amateur. The template below makes the complaint and the requested resolution explicit, which is what gets results. The best soft-skills outcome is invisible — a complaint resolved on the first email, no callback chain, no escalation.

Subject: Complaint — order #84219, undelivered after 14 days

Dear Customer Service Manager,

I am writing to make a formal complaint about order #84219, placed on your website on 1 May 2026 (confirmation email attached). Your published delivery time was three to five working days. As of today, 18 May, the order has not arrived and the tracking page has shown "Out for delivery" since 6 May.

I have called your customer service line three times (on 9 May, 12 May, and 15 May, reference numbers 4421, 4587, and 4733). I was told on each occasion that the matter would be escalated and that I would receive a callback within 24 hours. No callback was received.

I am requesting one of two outcomes: either the order is delivered by 25 May with confirmation of a tracking update, or a full refund of S$189.50 is credited to my original payment method by 25 May. Please confirm by reply which of these you will action.

Yours faithfully,
Mr. R. Subramaniam
Mobile: +65 9876 5432
ram.subramaniam@example.com

The detail is doing the work. Dates, order numbers, reference numbers, and the specific amount remove every “we’ll look into it” loophole. The two clear options at the end give the recipient a concrete choice and a deadline. Anger does not appear; the email is impossible to wave away as unreasonable. If you find yourself wanting to write “this is unacceptable” or “I am extremely disappointed”, delete those phrases. They weaken the email by making it about you instead of about the unresolved transaction. The same firmness-without-aggression is the heart of an apology email at work — the registers are mirror images of each other.

If you would like to build the assertive-but-respectful tone that gets these complaints resolved in person as well as in writing, our Communicate With Confidence course covers both written and verbal escalation in a one-day workshop format.

Worked template 4 — sending a formal email with an attachment

The attachment is the part of formal emails that goes wrong most often. The most common mistake is mentioning the attachment in the body and then forgetting to actually attach it. The second most common mistake is naming the file “Document1.pdf” — a name that tells the recipient nothing and gets buried instantly in their downloads folder. The third is sending a 25MB attachment to a Gmail account that bounces silently.

Five rules for attachments in a formal email.

1. Mention the attachment in the body. One sentence: “Attached is the signed contract and the supporting documentation.” If you do not mention it, the recipient may not notice the paperclip icon.
2. Name the file properly. “Smith Jane CV 2026.pdf” not “CV.pdf”. “Northwind Q2 Invoice 2026-05.pdf” not “Invoice.pdf”. The file name is what the recipient sees when they save the attachment, six months from now, looking for it.
3. Use PDF for documents you do not want edited. Word documents are convenient to send, but the formatting drifts between versions and the recipient can edit the file unintentionally. PDF is the formal default.
4. Check the size. Most corporate email systems reject attachments over 20MB. If your attachment is large (a video, a high-resolution scan), upload it to OneDrive or Google Drive and send the link instead, with a one-line note explaining why.
5. Open the attachment after attaching, before sending. It catches two errors: the wrong file (you have attached last quarter’s invoice instead of this quarter’s), and a corrupted file (PDFs occasionally save in a broken state).

A short template:

Subject: Signed contract — Northwind/Acme — please file for your records

Dear Ms. Lim,

Please find attached the signed master services agreement between Northwind Pte Ltd and Acme Solutions, executed on 16 May 2026.

I am also attaching the two appendices referenced in section 4.2 (data-processing addendum and pricing schedule). The full set of three files is enclosed.

Please confirm receipt and that the documents are in order. If anything is missing or unclear, I am available on +65 9123 4567 to walk through any section.

Yours sincerely,
James Wong

Writing formal emails in English when English isn’t your first language

Most formal-email guides are written for people whose first language is English. If yours is not — and in Singapore, working with colleagues across Southeast Asia, that is the majority of professionals I train — formal email writing in English has six common patterns that mark the message as ESL even when the grammar is technically correct.

1. The over-long opening. Writers translating from Mandarin, Tamil, Bahasa, or Tagalog often open with several lines of polite preamble before stating the request. In formal English, the request goes in the first sentence. “Trust this email finds you well. Hope all is good at your end. I am writing today because…” Cut straight to “I am writing to request…”. The preamble is not rude in your first language. In English it makes the reader wait.

2. Direct translation of polite forms. “Please do the needful,” “Revert back at the earliest,” and “Kindly find attached” are direct translations of polite phrases from other Englishes (Indian English, Singapore-Malaysia English). They are not wrong. They are recognisable. But in international formal writing they read as a regional variant. Replace with: “Please action this,” “Please reply when you can,” and “Attached is…”.

3. Wrong tense in requests. “I am wanting to apply” / “I am needing your approval” — present continuous instead of present simple. The fix is one word: “I want to apply” / “I need your approval”. Or, more formally, “I would like to apply” / “I would like to request your approval”.

4. “Kindly” overuse. “Kindly” once in an email is polite. “Kindly” four times reads as servile and is a strong ESL tell. Replace most instances with “please”, and several with nothing at all. “Kindly find attached the report” is more polished as “Attached is the report.”

5. Comma-splice greetings. “Dear Sir,” followed by a lowercase sentence (“i am writing to ask…”) or by a sentence with no proper subject. The greeting ends with a comma. The next line starts with a capital letter and a complete sentence. (“Dear Sir, / I am writing to ask…”).

6. Sign-off mismatches. “Yours faithfully,” with a named greeting (“Dear Mr. Lee,”) is wrong. The pairing is: “Dear Mr. Lee,” / “Yours sincerely,” — and “Dear Sir or Madam,” / “Yours faithfully,”. The rule is older than email and worth getting right. It signals you know the convention.

Over 24 years I have trained 48,000+ working professionals at 12,600+ companies on exactly this skill, and the ESL patterns above are the first thing we fix in the first hour of class.

Formal email phrasing in Spanish and German (quick reference)

A short reference for the two most-asked non-English formal-email languages. Both have a stricter formal/informal distinction than modern English does. Spanish “usted” and German “Sie” are like the dollar sign in an Excel formula — small markers that lock the meaning in place. Drop them and the sentence still makes sense, but it changes who you sound like.

Spanish (formal — Latin America and Spain).

Part	Formal Spanish	English equivalent
Greeting (name known)	Estimado Sr. Pérez: / Estimada Sra. Pérez:	Dear Mr./Mrs. Pérez,
Greeting (name unknown)	A quien corresponda:	To Whom It May Concern,
Opening	Le escribo para…	I am writing to…
Sign-off	Atentamente,	Yours sincerely,
Formal “you”	usted (verb in 3rd person singular)	(no English equivalent — English has only one “you”)

Note the colon after the greeting in Spanish, not a comma. Use “usted” verb forms throughout the email. Switching to “tú” in a formal email reads as disrespectful.

German (formal).

Part	Formal German	English equivalent
Greeting (name known)	Sehr geehrter Herr Müller, / Sehr geehrte Frau Müller,	Dear Mr./Mrs. Müller,
Greeting (name unknown)	Sehr geehrte Damen und Herren,	Dear Sir or Madam,
Opening	Hiermit schreibe ich Ihnen, um…	I am hereby writing to…
Sign-off	Mit freundlichen Grüßen,	Yours sincerely, / Kind regards,
Formal “you”	Sie (capitalised, always, in formal writing)	(no English equivalent)

In German formal email, the “Sie” form is non-negotiable. Switching to “du” is reserved for friends, family, and children. Capitalising “Sie” (and all its forms — Ihnen, Ihre) shows that you know the convention; lowercase “sie” means “she” or “they”, which the reader will register as a mistake.

A small but useful detail in both languages: the formal greeting is followed by a line break, then the body starts. In Spanish and German, the first word after the greeting starts with a lowercase letter, because the greeting line ends with a comma and the sentence carries on across the break. This is a real convention in both languages and gets caught by spellcheck as an “error”. It is not.

Closing

You now have the full picture of how to write a formal email end to end. The structural anatomy (subject, greeting, body, closing, signature). The no-name greeting decision tree. Four copy-paste templates for the most common situations (job application, professor, complaint, attachment). The six common ESL-writer patterns to clean up. And a short reference for Spanish and German.

Pick one formal email on your desk this week — one you have been putting off, one you are not sure how to start, one you wrote last week and want to upgrade. Run it through the five-part structure. Check the greeting against the no-name decision tree. Cut the opening preamble. Add the specific dates and reference numbers that make the email impossible to ignore. The whole exercise takes about ten minutes the first time and three minutes by the third time. Do try it out. Once you have done it on your own emails, the workflow is permanent — and the recipients on the other end will start replying faster. I hope you’ll like this approach. It is the same one we teach in the writing-professional-emails workshop, and the feedback I get from participants two months later is always the same: “I get more replies, and they come quicker.”
