Email and Letter Expressions: Dear Sir/Madam, Yours Sincerely, I Am Writing To

What this session covers

Formal emails and letters use fixed expressions that students must memorise. The opening: 'Dear Sir/Madam' (when you do not know the name), 'Dear Mr Smith' (when you know the name). The first sentence: 'I am writing to apply for...', 'I am writing in reply to...'. Common phrases: 'please find attached', 'thank you for your email', 'I look forward to hearing from you'. The closing: 'Yours sincerely' (when you used the name), 'Yours faithfully' (when you used Sir/Madam), 'Best regards' (slightly less formal). Each expression has a fixed form that cannot be changed. Students who know these chunks can write professional emails and letters for jobs, school applications, official requests, and any formal communication. Students who do not know them often use casual phrases ('Hi there', 'Thanks!') in formal contexts where they sound out of place. This lesson covers the most useful expressions at B1 level.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
When your students write a formal email or letter — for a job application, a school request, an official complaint — do they know the fixed expressions for opening, common phrases, and closing? Or do they use casual phrases that sound wrong in formal contexts?
Q2
Which of these have you seen your students get wrong or avoid using altogether?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
The basic structure of a formal letter or email:

1. OPENING (greeting):
Dear Sir/Madam, (you do not know the name)
Dear Mr Smith, (you know the family name — male)
Dear Mrs Jones, (you know the family name — married woman)
Dear Ms Brown, (you know the family name — woman, marital status not specified)

2. FIRST SENTENCE (reason for writing):
I am writing to apply for the position of teacher.
I am writing to enquire about the timetable.
I am writing in reply to your letter of 15 March.

3. MIDDLE (the message)
[Body of the letter]

4. CLOSING (final greeting):
Yours sincerely, (when you used the person's name in the opening)
Yours faithfully, (when you used Sir/Madam in the opening)
Best regards, / Kind regards, (slightly less formal)

Why does formal English have such fixed structures? Why must students learn each part?

Formal letters and emails follow a fixed structure that has settled over centuries of business and official communication. Each part has a specific job. The opening greeting signals respect and tells the reader the level of formality. The first sentence states the purpose clearly so the reader knows immediately what the letter is about. The closing greeting must match the opening — 'Yours sincerely' if you named the person, 'Yours faithfully' if you used Sir/Madam. Mixing them up signals that the writer does not know the conventions. Students who understand the structure can write professional letters for any purpose. Students who do not produce letters that look unprofessional, even if the content is good. The teaching focus should be on the fixed expressions for each part — not on creative writing.

2
Matching the opening to the closing:

FORMAL FORMAT 1 — when you do NOT know the name:
Opening: Dear Sir/Madam,
Closing: Yours faithfully,

FORMAL FORMAT 2 — when you DO know the name:
Opening: Dear Mr Smith, / Dear Mrs Jones, / Dear Ms Brown,
Closing: Yours sincerely,

LESS FORMAL — for emails to known contacts:
Opening: Dear Mr Smith, / Hi Mr Smith, (very casual)
Closing: Best regards, / Kind regards,

Why is the matching of opening and closing important?

The match between opening and closing is one of the most important conventions in formal English writing. 'Dear Sir/Madam' goes with 'Yours faithfully'. 'Dear Mr Smith' (with the name) goes with 'Yours sincerely'. Native English readers expect this match — getting it wrong (using 'Yours sincerely' with 'Dear Sir/Madam', or 'Yours faithfully' with 'Dear Mr Smith') signals a writer who does not know the conventions. The rule is fixed and must be drilled. The reason behind the rule is historical — sincerely means 'truly yours' (when you know the person), faithfully means 'in faithful service' (when you do not). For B1 students, the practical rule is: name + sincerely, no-name + faithfully. Less formal contexts (Best regards, Kind regards) work in both cases.

3
Useful fixed phrases for the body:

I am writing to apply for the position of teacher.
I am writing to enquire about the new course.
I am writing in reply to your email of 5 May.
I am writing to complain about the service.

Thank you for your email of 3 June.
Thank you for your reply.
Thank you for taking the time to write.

Please find attached my CV.
Please find enclosed the documents you requested.

I look forward to hearing from you.
I look forward to receiving your reply.
I look forward to meeting you next week.

If you require any further information, please do not hesitate to contact me.

Why are these fixed phrases so useful? Why not just write the letter normally?

Formal English uses fixed phrases for common letter functions. Stating the purpose of writing ('I am writing to...'). Acknowledging a previous communication ('Thank you for your email of 3 June'). Pointing to attachments ('Please find attached'). Inviting a response ('I look forward to hearing from you'). Offering further help ('Please do not hesitate to contact me'). Each phrase is a fixed chunk that must be learned. Students who know these chunks can write formal letters quickly and accurately. Students who try to invent their own phrases often produce English that sounds wrong. 'I look forward to hearing from you' (right). 'I look forward to hear from you' (wrong — needs -ing because of 'to' before a noun-like phrase). The fixed chunks prevent these errors.

The Pattern — What You Just Discovered

Formal emails and letters use fixed expressions for opening greetings, common phrases, and closing greetings. The opening must match the closing: 'Dear Sir/Madam' goes with 'Yours faithfully'; 'Dear Mr Smith' (with name) goes with 'Yours sincerely'. Useful body phrases include 'I am writing to', 'thank you for', 'please find attached', and 'I look forward to + -ing' (note the -ing form). Students must learn these as fixed chunks — they cannot be invented. The expressions in this lesson cover the most common formal communication needs: job applications, school requests, official enquiries, formal complaints.
Expression Function When to use Notes
Dear Sir/Madam, Opening — you do not know the name Job applications, official enquiries, complaints Always followed by 'Yours faithfully' at the end.
Dear Mr/Mrs/Ms [Surname], Opening — you know the name All formal letters where you have the name Followed by 'Yours sincerely' at the end. Use Ms if marital status is not specified.
Yours faithfully, Closing — match for Dear Sir/Madam After Dear Sir/Madam openings NEVER pair with Dear Mr Smith — that takes Yours sincerely.
Yours sincerely, Closing — match for Dear [Name] After Dear Mr/Mrs/Ms openings NEVER pair with Dear Sir/Madam — that takes Yours faithfully.
Best regards, / Kind regards, Closing — slightly less formal For semi-formal emails, regular business contacts Works after either kind of opening. Less formal than 'Yours sincerely/faithfully'.
I am writing to + verb Opening sentence — state purpose Always at the start of the letter Followed by an infinitive: I am writing to apply, to enquire, to complain.
Thank you for + noun/-ing Acknowledging something received In reply to a previous letter or action Thank you for your email, for your help, for taking the time to write.
Please find attached / enclosed Pointing to documents sent with the letter When sending documents, files, photos 'Attached' for emails (digital files). 'Enclosed' for paper letters.
I look forward to + -ing Inviting a response or future event Towards the end of the letter Note: -ing (not 'to + verb'). 'Look forward to hearing' — not 'to hear'.
Please do not hesitate to contact me Offering further help Towards the end, before the closing Formal way to invite questions. Used when the writer wants to be helpful.
With reference to / Further to Connecting to previous communication Opening or in body of reply letters With reference to your letter of 15 March. Further to our conversation yesterday.
Usage Notes

NOTE 1 — Match opening and closing: This is the most important rule. Dear Sir/Madam → Yours faithfully. Dear [Name] → Yours sincerely. Mismatching these signals a writer who does not know formal conventions. For semi-formal emails, 'Best regards' or 'Kind regards' works after either opening.

NOTE 2 — 'I look forward to' takes -ing: This is a common grammar error in fixed phrases. The pattern is 'I look forward to + -ing'. 'I look forward to hearing from you' (right). 'I look forward to hear from you' (wrong). The 'to' here is a preposition, not part of the infinitive. Drill this pattern as a fixed chunk.

NOTE 3 — Use Ms for women if uncertain: 'Mrs' implies the woman is married. 'Miss' implies unmarried. 'Ms' (pronounced 'miz') is neutral and works regardless of marital status. For modern formal English, Ms is often the safer choice when marital status is not known or relevant.

NOTE 4 — Casual phrases sound wrong in formal letters: 'Hi there', 'Hey', 'Thanks!', 'Cheers', 'Bye' all sound out of place in formal communication. For job applications, school requests, official enquiries — always use the formal expressions. Save casual phrases for emails to friends.

NOTE 5 — Formal letters and emails differ slightly: Email is generally less formal than paper letters. 'Best regards' is fine in emails to business contacts you know. 'Yours sincerely' is more formal and suits paper letters. For very formal emails (job applications, official complaints), use the same conventions as paper letters.

Note

Email and letter expressions are immediately practical for any student who will write formal communication — for jobs, school, university applications, complaints, official requests. The expressions in this lesson are fixed chunks that must be memorised. Students who know them can write professional letters quickly. Students who do not often produce letters that sound wrong, even when the grammar is correct. Cultural context matters: the conventions of English formal letters may differ from those in the student's first language. Greetings, closings, and the level of formality vary across cultures. Teachers should explicitly teach the English conventions and explain that direct translation from the first language often produces wrong English.

💡

Show real examples of formal letters and emails — printed-out job applications, school requests, official complaints (with personal details removed). Students see the conventions in real use. Then have them write their own examples for practice — a job application, a request to a head teacher, an enquiry to a college. Real-life writing makes the chunks memorable.

Common Student Errors

Dear Sir/Madam, [body of letter] Yours sincerely, John Smith.
Dear Sir/Madam, [body of letter] Yours faithfully, John Smith. / Dear Mr Brown, [body of letter] Yours sincerely, John Smith.
WhyThe opening and closing must match. Dear Sir/Madam pairs with Yours faithfully. Dear Mr Brown (with the name) pairs with Yours sincerely. Mixing them up signals a writer who does not know the conventions.
I look forward to hear from you soon.
I look forward to hearing from you soon.
Why'Look forward to' takes -ing, not 'to + verb'. The 'to' here is a preposition, not the start of an infinitive. The pattern is fixed: 'look forward to + -ing'. Other examples: I look forward to seeing you. I look forward to receiving your reply.
Hi there! I am writing to apply for the job at your school.
Dear Sir/Madam, I am writing to apply for the position of teacher at your school.
Why'Hi there!' is too casual for a formal job application. The formal opening is 'Dear Sir/Madam,' or 'Dear Mr/Mrs [Surname],'. Casual greetings (Hi, Hello, Hey) are wrong in formal letters. Formal communication needs formal openings.
Please find attach my CV with this email.
Please find attached my CV with this email.
WhyThe fixed expression is 'please find attached' (with the past participle 'attached'), not 'attach' (the base verb). The phrase comes from passive voice — the document has been attached. Always 'please find attached' or 'please find enclosed'.
Dear Mrs, I am writing to apply for the teaching position.
Dear Mrs Smith, / Dear Madam, / Dear Sir/Madam, I am writing to apply for the teaching position.
Why'Dear Mrs' alone is not complete — it needs a surname (Mrs Smith). If you do not know the surname, use 'Dear Madam' (when you know the person is a woman) or 'Dear Sir/Madam' (when you do not know). Mrs alone is incomplete and unusual.

Check Your Understanding — Part 1

Choose the best email or letter expression for each context. Think about the formality and the matching of opening and closing.

A student is writing a formal job application to a school. She does not know the name of the head teacher. She needs to choose the right opening.
Pick the most appropriate word:
A teacher is writing a formal letter to Mr Adeyemi, the head of the local education department. The opening is 'Dear Mr Adeyemi,'. What closing matches?
Pick the most appropriate word:
A student is finishing a formal email to a university enquiry office. She wants to invite their reply.
Pick the most appropriate word:
A teacher is sending a CV by email and wants to mention that the CV is included in the email.
Pick the most appropriate word:
A worker is writing the first sentence of a formal complaint letter to a service company.
Pick the most appropriate word:
0 / 5 answered

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence has a problem with a formal email or letter expression. Find the error, write the correct version, and explain.

Dear Sir/Madam, [body] Yours sincerely, John Adebayo.
Write the correct sentence:
Explain why it is wrong:
Dear Sir/Madam, [body] Yours faithfully, John Adebayo.
The opening 'Dear Sir/Madam' (without a name) requires the closing 'Yours faithfully'. 'Yours sincerely' is for letters where you used the person's name (Dear Mr Smith). Mixing them up is a very common error and signals a writer who does not know formal conventions.
I look forward to hear from you about the position.
Write the correct sentence:
Explain why it is wrong:
I look forward to hearing from you about the position.
'Look forward to' takes -ing, not 'to + verb'. The 'to' here is a preposition, not the start of an infinitive. The fixed phrase is 'I look forward to hearing'. This is the most common grammar error in formal letter writing.
Hi there! I am writing to apply for the teaching position at your school.
Write the correct sentence:
Explain why it is wrong:
Dear Sir/Madam, I am writing to apply for the teaching position at your school. / Dear Mr Smith, I am writing to apply for the teaching position at your school.
'Hi there!' is far too casual for a formal job application. The formal opening is 'Dear Sir/Madam' (no name known) or 'Dear Mr/Mrs [Surname]' (name known). Casual greetings sound wrong in professional contexts and may damage the writer's chances.
Please find attach my qualifications and references along with this letter.
Write the correct sentence:
Explain why it is wrong:
Please find attached my qualifications and references along with this letter.
The fixed phrase uses the past participle 'attached', not the base verb 'attach'. 'Please find attached' is the conventional formal phrase. The same applies to 'enclosed' for paper letters: 'please find enclosed'.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — The structure of a formal letter (5 min): Show the four parts of a formal letter. OPENING (Dear Sir/Madam, or Dear Mr/Mrs [Name]). FIRST SENTENCE (I am writing to...). BODY (the message). CLOSING (Yours faithfully, or Yours sincerely,). Establish that each part has fixed conventions.

2

STEP 2 — Match opening and closing (6 min): Drill the matching rule. Dear Sir/Madam pairs with Yours faithfully. Dear Mr Smith pairs with Yours sincerely. Best regards works for less formal emails. Practise five examples — students must produce both the right opening and the matching closing.

3

STEP 3 — Useful body phrases (8 min): Drill the most useful fixed phrases. 'I am writing to apply / to enquire / to complain.' 'Thank you for your email / your help.' 'Please find attached / enclosed.' 'I look forward to hearing from you.' 'Please do not hesitate to contact me.' Practise each in context.

4

STEP 4 — The look forward to grammar (5 min): Spend focused time on the most error-heavy phrase. 'I look forward to + -ING' (not to + verb). Drill: 'I look forward to hearing from you.' 'I look forward to seeing you.' 'I look forward to receiving your reply.' This pattern is fixed and must be memorised.

5

STEP 5 — Write a real letter (6 min): Each student writes a short formal email or letter — a job application, a school request, an official enquiry. They must use the right opening, at least three body phrases, and the matching closing. Share in pairs. Partner checks for correctness.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 Formal letter conventions wall (display)
Create a wall display with three sections: OPENINGS, BODY PHRASES, CLOSINGS. Under openings, show 'Dear Sir/Madam' (no name) and 'Dear Mr/Mrs [Surname]' (with name). Under body phrases, list the most useful fixed expressions. Under closings, show 'Yours faithfully' (matches Sir/Madam) and 'Yours sincerely' (matches name) and 'Best regards' (less formal). Refer to the wall when students write.
Example sentences
OPENINGS: Dear Sir/Madam (no name), Dear Mr/Mrs/Ms [Surname] (name known), Hi [First name] (casual emails)
BODY PHRASES: I am writing to apply / enquire / complain, Thank you for your email, Please find attached, I look forward to hearing from you
CLOSINGS: Yours faithfully (matches Sir/Madam), Yours sincerely (matches name), Best regards / Kind regards (less formal)
2 Match opening to closing (oral drill)
Call out an opening. Students must produce the matching closing. Drill until automatic. Then reverse — call out a closing and students give the matching opening.
Example sentences
Teacher: 'Dear Sir/Madam' → Student: 'Yours faithfully'
Teacher: 'Dear Mr Adebayo' → Student: 'Yours sincerely'
Teacher: 'Yours sincerely' → Student: 'Dear [name]' (Dear Mr/Mrs/Ms + Surname)
Teacher: 'Yours faithfully' → Student: 'Dear Sir/Madam'
3 Write a formal letter (writing task)
Each student writes a short formal letter or email for a real or imagined situation: a job application, a school enquiry, a complaint about a service. The letter must include all parts — opening, first sentence, body, closing. Partner reads and checks for correctness.
Example sentences
Sample situations: Apply for a teaching job at the local secondary school. Enquire about the registration deadline at a local college. Complain to the bank about a problem with your account. Request information from the local government office about new community projects.

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Build the formal vocabulary further with more useful expressions: 'I would be grateful if you could...', 'I would appreciate your reply...', 'with regard to...', 'in connection with...'. These add range for different formal situations.
Teach the layout of formal letters — sender's address top right, date below, recipient's address top left, then the greeting. The visual layout matters as much as the words.
Connect to CV writing — students who can write formal letters can also write professional CVs. The same conventions of formality apply.
Look at email-specific conventions — subject lines, reply chains, signatures. Email has its own conventions in addition to the formal letter conventions.
Ask students to find real formal letters or emails (in newspapers, on websites, in school office) and identify the conventions. Real-world examples reinforce the patterns.
What is the one change you will make next time you teach this vocabulary?

Key Takeaways

1 Formal emails and letters use fixed expressions that students must memorise. The structure: opening greeting, first sentence (purpose), body, closing greeting.
2 The opening must match the closing. Dear Sir/Madam → Yours faithfully. Dear Mr/Mrs [Name] → Yours sincerely. Best regards / Kind regards works for less formal emails.
3 Useful body phrases: 'I am writing to + verb' (state purpose). 'Thank you for + noun' (acknowledge). 'Please find attached + document' (point to attachments). 'I look forward to + -ing' (invite reply).
4 The most common grammar error is 'I look forward to hear' instead of 'I look forward to hearing'. The 'to' here is a preposition — always followed by -ing.
5 Casual greetings (Hi, Hello, Hey) and casual closings (Cheers, Thanks) are wrong in formal letters. Formal communication needs formal expressions throughout. Match the formality to the context.
