# How to Write a Cover Letter: Step by Step, With Examples

> To write a cover letter, read the posting and pick the two or three things it asks for most, find one specific thing about the company, then write three or four short paragraphs on one page. Open with the role and that company detail, prove each ask with a real result, and close by asking for a conversation.

## Key takeaways

- A cover letter works best as three or four short paragraphs on one page: an opening, one or two paragraphs of proof, and a close.
- The posting tells you what to write about: pick the two or three asks it repeats or lists first, and prove each one with a real result.
- One specific detail about the company in the first paragraph shows the letter was written for that job and no other.
- A cover letter should add context the resume can't, such as why this company, what you'd do first, or why you're changing direction.
- Use the same name, contact details and font as your resume so the two read as one application.

A cover letter is a short letter, sent with your resume, that explains why you want this job and proves you can do it. The resume lists what you've done; the letter picks the two or three parts that matter most for this role and connects them to the company. If a blank page makes this feel bigger than it is, the steps below break it into pieces you can do one at a time.

## How do you write a cover letter, step by step?

Write a cover letter in this order: research first, evidence second, opening last.

1. **Read the posting twice.** Mark the two or three asks that appear first or come up more than once. Those are what your letter has to prove.
2. **Find one specific thing about the company.** A recent launch, a campaign, a change in their messaging, a market they've entered. Our guide to [researching a company](/guides/how-to-research-a-company-before-an-interview/) covers where to look in about twenty minutes.
3. **Match each ask to a result from your resume.** One result per ask, with a number if you have one. If you can't prove an ask honestly, leave it out.
4. **Write the middle first.** One short paragraph per result: what you did, what changed, and why it matters for this role.
5. **Write the opening.** The role you're applying for, plus the company detail from step 2 and why it caught your attention.
6. **Write the close.** What you'd focus on first, or why now, and a plain request for a conversation.
7. **Cut and read it aloud.** Take out anything that repeats your resume without adding context, then read it out loud. If a sentence sounds like nobody you know, rewrite it the way you'd say it.

Most of the time goes into steps 1 to 3. Once you know your evidence, the writing goes quickly.

## What is the standard cover letter format?

The standard cover letter format is a one-page business letter: your contact details, the date, a greeting, three or four paragraphs, and a sign-off with your name. Columbia's career center recommends [one page or less, about three or four paragraphs, single spaced](https://www.careereducation.columbia.edu/resources/how-and-why-write-great-cover-letter). A 10 to 12 point font keeps it readable.

| Part | What goes in it | Length |
|---|---|---|
| Header | Your name, email, phone, city and LinkedIn or portfolio link | 2 to 4 lines |
| Date and recipient | Today's date; the hiring manager's name, title and company if you're sending a document | 3 to 4 lines (optional in an email or form) |
| Greeting | "Dear [Name]," or "Dear [Team] Hiring Manager," | 1 line |
| Opening | The role, plus one specific thing about the company | 2 to 3 sentences |
| Proof | One or two results that match the posting's top asks | 1 or 2 short paragraphs |
| Close | What you'd focus on first and a request for a conversation | 2 to 3 sentences |
| Sign-off | "Best regards," or "Thank you," and your full name | 2 lines |

Match the header, font and margins to your resume, as Oklahoma State's career services suggests ([use the same header from your resume](https://casinfo.okstate.edu/images/pdf/career-resources/Cover_letter_packet.pdf)), so the two documents look like one application. Save it as a PDF named something clear, like `Firstname-Lastname-Cover-Letter.pdf`, unless the posting asks for another format.

### Cover letter format in an email or application form

When the letter goes in an email body or a form field, drop the header, date and recipient address. Start with the greeting, keep the same paragraphs, and put your contact details under your name. In an email, the subject line does the work of the header: "Application: Brand Manager, [Your name]".

## Cover letter example for a marketing job

This example is for a social media manager role. Treat it as a starting point and rewrite it the way you'd say it: the hiring manager is hiring you, and a letter in your own voice is the one they remember.

```text
[Your name]
[Email] · [Phone] · [City] · [LinkedIn or portfolio URL]

[Date]

Dear [Hiring manager's name],

I'm applying for the Social Media Manager role at [Company]. Your shift this year toward [specific change, e.g. founder-led video on TikTok] caught my attention, because it's the kind of content I've spent the last two years building.

At [Current company], I run our organic social across [channels]. I rebuilt our content calendar around [format or series], and in [timeframe] our [metric, e.g. average engagement rate] went from [X] to [Y]. I also set up our creator program, which now brings in [result, e.g. X pieces of usable content a month] for [budget or cost].

Your posting asks for someone who can [their top ask, in their words]. I'd start by [one concrete first step], because [short reason tied to what you noticed].

I'd welcome a conversation about the role. Thank you for your time.

Best regards,
[Your name]
```

Notice what the example does: one company detail in the opening, two results with numbers, one sentence about what they'd do first, and a short close. Fill in the brackets now, even roughly; a rough draft with real numbers is easier to improve than a polished one without them.

If you'd like a first draft to edit, Recon writes a cover letter from your resume and the posting, and leaves a [placeholder] wherever a line needs a fact only you know rather than inventing one.

For role-by-role versions, see the examples for [marketing managers](/cover-letters/marketing-manager/), [social media managers](/cover-letters/social-media-manager/) and the full list of [marketing cover letter examples](/cover-letters/).

## What should a cover letter include?

A cover letter should include the job you're applying for, one specific reason you want to work at this company, two or three pieces of proof that you can do what the posting asks, and a request for a conversation. Everything else is optional.

Good things to add when they apply:

- **Context the resume can't give.** A career change, a move, a gap, or why you're stepping down or sideways.
- **A referral.** "[Name] on your team suggested I apply" belongs in the first sentence.
- **What you'd do first.** One concrete idea shows you've thought about the job, not only about getting it.
- **A link to your work.** For creative, content and social roles, a [portfolio](/career-guides/marketing-portfolio/) link does more than a paragraph of description.

## What should you leave out of a cover letter?

Leave out anything that repeats your resume line by line, general claims you can't prove ("passionate, results-driven team player"), salary history unless the posting asks for it, and reasons for leaving that sound negative. Each of these takes space from the proof that gets you the interview.

| Instead of | Write |
|---|---|
| "I am a passionate, results-driven marketer." | "Last year I grew our email list from [X] to [Y] while keeping unsubscribes under [Z]%." |
| "I believe I would be a great fit." | "Your posting asks for [ask]. At [Company], I [result that proves it]." |
| "Please find attached my resume." | Nothing. The resume is attached; use the line for proof. |
| "I'm looking to grow my skills." | "I want to own [area] end to end, which is what this role does." |

## How do you write a cover letter with no experience?

Write a cover letter with no experience by proving the posting's asks with what you have done: class projects, internships, part-time jobs, volunteering, a side project or your own content. Hiring managers for entry-level roles expect to train you, so they're reading for effort, curiosity and how clearly you write.

Pick one project and describe it like work: what you set out to do, what you made, and what happened. "I ran the Instagram account for our campus club and grew it from [X] to [Y] followers in a semester by [what you did]" is real evidence. Our [entry-level marketing cover letter](/cover-letters/entry-level-marketing/) and [internship cover letter](/cover-letters/marketing-internship/) pages have full examples, and the [career change cover letter](/cover-letters/career-change/) covers moving in from another field.

## Is a cover letter still worth writing?

Yes, when the application asks for one or allows one, because it's the only part of your application written for this specific job. Some recruiters skip cover letters and some hiring managers read every one, and you can't tell which you'll get, so a short, specific letter is a safe bet. For marketing roles it also doubles as a writing sample.

If a form makes the cover letter optional and you're short on time, a strong three-paragraph letter is better than none, and better than a long generic one.

## FAQ

### How long should a cover letter be?

A cover letter should fit on one page, in three or four short paragraphs, which usually lands between 250 and 400 words. Shorter is fine when every line carries proof. Our guide on [cover letter length](/cover-letters/how-long-should-a-cover-letter-be/) covers forms with character limits and email versions.

### How do you start a cover letter?

Start with the role you're applying for and one specific detail about the company or a referral, in the first one or two sentences. Skip "My name is" and "I am writing to apply"; your name is already on the letter. See [how to start a cover letter](/cover-letters/how-to-start-a-cover-letter/) for opening lines by situation.

### Who do you address a cover letter to?

Address it to the hiring manager by name if you can find it, for example "Dear Jordan Lee,". If you can't, "Dear [Team] Hiring Manager," is clear and polite. Our guide on [how to address a cover letter](/cover-letters/how-to-address-a-cover-letter/) covers how to find the name.

### Should a cover letter be the same for every job?

No. Keep a base version with your strongest results, but change the opening, the company detail and which results you lead with for each job. Matching the posting's top asks is what makes the letter worth reading.

### How do you end a cover letter?

End with one sentence on what you'd bring or focus on, a short request for a conversation, and a sign-off such as "Best regards," followed by your name. See [how to end a cover letter](/cover-letters/how-to-end-a-cover-letter/) for closing lines.
