The 6 Essential Parts of a Cover Letter

Staring at a blank page is the hardest part of writing a cover letter — but a letter stops being intimidating the moment you see it as six small components rather than one big essay. Each part has a distinct job, takes only a few sentences, and follows conventions Canadian employers see every day. Once you can name the parts, you can write them in any order, then assemble a polished letter in well under an hour.

Key Takeaways

• Every effective cover letter contains six parts: heading, greeting, opening paragraph, body paragraphs, closing paragraph and signature block.
• The heading and greeting establish professionalism; a named recipient beats a generic greeting wherever discoverable.
• The opening names the role and hooks the reader; the body proves fit with specific, quantified examples.
• The closing requests the interview; the signature ends cleanly.
• Aim for roughly 250 to 400 words total, fitting on a single page.
• Reuse your strongest body paragraphs across applications — tailor the opening and closing each time.

Part 1: The Heading

The heading carries your contact details and the date, mirroring the look of a professional business letter. Include:

• Your name (many writers set it slightly larger or bold)
• City and province, phone number, email address, LinkedIn URL
• The date
• Optionally, the recipient's name, title, company and address

If you are pasting the letter into an email body or a portal rather than attaching it, trim the heading to a two-line contact signature. Keep the formatting plain — graphics and decorative elements travel badly across systems.

Part 2: The Greeting

The greeting sets the tone in a single line, and its quality signals the effort behind the application.

• Best option: a real name — "Dear Ms. Okafor," or "Dear Mr. Boucher,"
• Acceptable fallback: "Dear Hiring Manager," — professional and unremarkable
• Avoid: "To Whom It May Concern," "Dear Sir/Madam," and "Hello!"

Finding a name is rarely hard: check the posting, the company's careers page, or LinkedIn. If you are uncertain of the person's honorific, the safest form is simply "Dear [Full Name]," — for example, "Dear Jordan Lee,".

Part 3: The Opening Paragraph

The opening has one job: make the next paragraph irresistible. In two to four sentences, it should:

1. Name the position you are applying for.
2. Deliver your hook — your single strongest relevant qualification for the role.
3. Signal genuine, specific interest in this employer.

Compare two openings:

Weak: "I am writing to apply for the Administrative Assistant position posted on your website. I have attached my resume for your consideration."

Strong: "When I saw the Administrative Assistant posting at Larkspur Legal, I jumped at the chance — three years of keeping a busy eight-lawyer office running smoothly, from client intake to billing, has prepared me for exactly this environment."

The strong version names the job, presents a concrete hook, and sounds like a person. For career changers, the opening is also the place to bridge gracefully: one sentence acknowledging the shift, one framing it as a strength.

Part 4: The Body Paragraphs

The body — typically one or two paragraphs, or a short paragraph plus a tight bulleted list — is where you prove you can do the work. This is the most important part of the letter, so write it last and spend your best effort here.

For each of the posting's top two or three requirements, build one proof unit: the situation in a clause, the action you personally took, and the result, quantified where honestly possible. For example:

"In my current role at Meridian Supplies, I coordinate logistics for three regional warehouses. Last year I consolidated our vendor onboarding process, cutting the average setup time by roughly a third. I also built the weekly reporting pack our leadership team now uses, replacing four separate spreadsheets."

Notice the pattern: requirement mentioned → action described → result measured. Match your two or three strongest proofs to the posting's most prominent requirements, and if the posting emphasizes a specific skill, tool or credential, name it in the same words the posting uses.

Part 5: The Closing Paragraph

The closing is short — two or three sentences — and does three things:

1. Reaffirm fit and interest in one line.
2. Thank the reader for their time.
3. Request the next step with confident, direct language.

A strong closing sounds like:

"I would welcome the opportunity to discuss how my warehouse coordination experience could support Meridian's operations team. Thank you for your time and consideration. I look forward to hearing from you."

Avoid passive, apologetic closings ("I hope to hear from you at your convenience") and pushy ones ("I will call you next Tuesday at 10 a.m."). Confident and courteous is the register you want.

Part 6: The Signature

The signature ends the letter cleanly. In attached or printed letters, use a complimentary close such as "Sincerely," or "Kind regards," followed by your typed full name. In email letters, the close and your name sit directly together, optionally followed by a one-line contact block with your phone and LinkedIn.

Assembling the Six Parts: A Quick Checklist

Part	Length	Quality test
Heading	3–5 lines	Every contact detail correct and current
Greeting	1 line	A real name, or the professional fallback
Opening	2–4 sentences	Names the role and hooks with your best qualification
Body	1–2 paragraphs	Proves the top requirements with quantified results
Closing	2–3 sentences	Thanks the reader and requests the interview
Signature	1–2 lines	Correct close, correct name spelled correctly

Total target: 250 to 400 words, one page. Read the finished letter aloud once — every sentence should either prove fit, show interest, or ask for the conversation.

Frequently Asked Questions

Which part of the cover letter is most important?

The body paragraphs, because they carry the evidence. But a close second is the opening sentence: if the first line fails, the rest may never be read. Write the body first while your examples are fresh, then craft an opening strong enough to earn it attention.

Is a bulleted list acceptable in the body of a cover letter?

Yes, used sparingly — one short list of three or four quantified achievements can improve skimmability. Keep the surrounding paragraphs in prose so the letter still reads like a person wrote it.

Do all six parts need to appear in an emailed cover letter?

In a condensed form, yes. When the letter travels in an email body, the heading compresses to a subject line and a signature block, but the greeting, opening, body and closing all remain essential — they are what distinguish a cover letter from a casual note.

How long should each part be?

Rough proportions: opening about 15 percent of the letter, body 60 percent, closing 15 percent, with heading, greeting and signature as fixed overhead. For a 350-word letter, that is around 50 words to open, 200 to prove, 50 to close — a balanced shape that keeps the evidence at the centre.

Final Thoughts

A cover letter is not a blank-page problem — it is six small writing tasks you can complete one at a time. Build a master document today containing your best body proofs and a polished signature block, then focus your tailoring energy on the greeting, opening and closing for each application. Pick a live posting, write the six parts, and send your next application knowing every component is doing its job.
