How to Write a Cover Letter: Structure, Examples, and What to Skip

Four paragraphs, and each one has a job to do. Most cover letters spend all four doing the first one. Below is what belongs in each, how long the whole thing should be, and the honest part nobody puts at the top: plenty of these are never opened, and the ones that are opened are read by the person deciding.

This guide covers what a cover letter is, what it does that a resume cannot, how to build it paragraph by paragraph, and the questions that stall people at the last minute: length, who to address it to, attachment or email body, and when writing one is a waste of your evening. If you are sending the letter as the body of an email, the email for job application templates show the subject line and sign-off.

What is a cover letter?

A cover letter is a short document, usually one page, sent with your resume when you apply for a job. It is written in full sentences, addressed to a person or a hiring team, and it argues for one role at one employer. On some forms and in some countries it is called an application letter or a letter of motivation. The name changes, the job does not.

It is not your resume rewritten in prose, and it is not an essay about your journey. It is a short, evidenced argument answering three questions the resume leaves open: why this employer, why this role, and why you rather than the next application in the pile. Four paragraphs covers all three.

What a cover letter does that your resume cannot

A resume and cover letter do different work, which is why employers ask for both. The resume is a structured record of titles, dates and bullets, built to be scanned in seconds and parsed by software. It reports facts and never explains them. Nothing on it says why you left an industry, why a two-year gap exists, or what you actually want next.

The letter is where that reasoning goes. It also does something structural: it decides which single piece of your history the reader looks at first. A resume gives equal visual weight to eight years of work. A letter says this is the part that matters for your job, and here is what happened.

Treat the two as one package: same name block, same font, same contact details, same file naming pattern. A letter typeset differently from the resume it arrives with looks borrowed, because it usually is.

The honest part: plenty of cover letters are never read

You should know this before you spend an hour on one. A recruiter screening several hundred applications works from the resume, the screening question answers and the required qualifications. On many application forms, including ones built on systems like Greenhouse and Workday, the cover letter field is marked optional, and optional fields get skipped by readers as well as by applicants. Recruiters disagree publicly about whether they read them, and the honest answer is that it depends on the company, the role and the week.

That is an argument for spending your effort where it pays, not for skipping the letter everywhere. In some situations the letter does more work than anything on the resume.

The four paragraphs, and the job each one does

A working cover letter runs roughly 250 to 400 words across four short paragraphs: an opening that earns the next paragraph, a paragraph on why this employer, a paragraph of evidence, and a close that asks for something. Written in that order, each one has exactly one job.

Paragraph one: the opening line

This is where most letters die, so it is worth an example. Here is the version almost everyone writes:

"I am writing to express my interest in the Marketing Coordinator position at Brightline Media, which I saw advertised on LinkedIn. I believe my skills and experience make me an excellent candidate for this role."

Two sentences, zero information. The first repeats what the application form already said. The second is a claim with nothing behind it, and every other applicant made the same claim. The same candidate, rewritten:

"I run the email program at a twelve-person agency. Over eight months I rebuilt our segmentation and took a 40,000-person list from a 14 percent open rate to 31 percent. Brightline is the first Marketing Coordinator posting I have read that puts lifecycle email at the center of the job instead of at the bottom of the list, which is why I am applying." Applying for a job in HR itself? The human resources cover letter samples run from HR assistant to HR business partner.

Same person, same job, roughly the same length. The rewrite leads with a concrete result, then names a detail from the posting to explain why this employer got the letter. The reader now knows what you do, how well you do it, and that you read the job description. That buys the second paragraph.

Tip: Write the opening last. It is far easier to pick your strongest line once the proof paragraph exists, and the sentence you were most proud of in the middle of the letter is often the one that belongs at the top.

Paragraph two: why this company

Name one specific thing and connect it to your work: a product they shipped, a market they moved into, a policy they published, a constraint visible in the job description. One real detail beats three sentences of praise, and praise is the trap here. "A recognized leader in the industry" could be written about any employer, which tells the reader you know nothing about this one.

The link back to you is the part people forget. Do not just observe the detail, say what it means for the work you would do. "You opened three new markets last year, and localized campaigns are the part of my current job I would happily do full time" only works for one company. That is the standard.

Paragraph three: the proof

One story told properly beats a list of four. Pick the accomplishment closest to the top requirement in the posting and give it a shape: the situation, what you personally did, and what changed. Personally is the load-bearing word. Plenty of letters describe what a team achieved while carefully avoiding what the writer contributed.

Use numbers where you honestly have them and scope where you do not. Not every job produces a metric. "First analyst on a three-person team, owning reporting for two regions" tells a reader as much as a percentage does, and it survives an interview. Never invent a figure. The follow-up question is always how you measured it.

Paragraph four: the close

Ask for something specific and stop. "Thank you for your time and consideration, I look forward to hearing from you at your earliest convenience" is polite noise that ends the letter on the reader's obligations. Compare it with this: "I would like to talk about how the segmentation work translates to a list your size. I am free for a call most afternoons, and my resume is attached." Confident, concrete, finished. Sign with your name and a phone number.

Tip: Read the letter back and delete every sentence that would still be true if you sent it to a different company. Whatever survives is the actual letter. If almost nothing survives, you have found the reason your applications are silent.

How long it should be, and how to send it

One page, always, and 250 to 400 words. Under 200 usually means you skipped the evidence. Over 500 means the reader is skimming, which defeats the point of choosing what they see first. If a form imposes a character limit, that limit is the brief: cut context, not evidence.

How you deliver it depends on where you are applying, and the rules are simple.

Who to address it to, and what to do when nobody is named

A name is better than no name, and it is findable more often than people assume. Spend ten minutes, not an hour.

If ten minutes produces nothing, write "Dear Hiring Manager". It is neutral, and nobody has been rejected for it. Skip "To Whom It May Concern" and "Dear Sir or Madam", which read as templates from another decade. At a small company, "Dear [Company] team" is fine and often warmer.

Tip: Never guess a name. Addressing the letter to the wrong person, or to someone who left last year, is worse than addressing nobody. If you are not sure that person is still in the role, use the generic greeting. Writing to a Spanish speaking employer? The greeting changes too, and our cover letter in Spanish examples show how.

When a cover letter is genuinely optional

Skip it when the posting says not to send one, when the form has no field for it, and when the employer scores structured criteria fields instead, as public sector applications often do. There the letter is not the assessed document and adding one changes nothing.

The harder case is an optional field at a large employer when you are a straightforward match: right title, right industry, right years, applying alongside hundreds of others. A tailored letter is a small edge there and a generic one is a small liability, because a letter that says nothing proves you send the same thing everywhere. If you have twenty minutes, write the real one. If you have five, submit without it and apply to fewer jobs properly.

How to write a cover letter for a teacher position

The same four paragraphs work for a teaching post, but a principal or a hiring panel reads them for different evidence. They want your license and subject in the first lines, one classroom moment that shows how you teach, and a sign that you read about the school rather than only the district posting. A letter that says only how much you love working with children reads like every other one in the folder.

Here is an opening written that way for an invented candidate: "I am applying for the fourth grade post at Lindell Elementary. I hold a state elementary license with a reading endorsement, and for three years my class has run guided reading groups every morning, the routine your posting puts at the center of your literacy block." For complete letters by career stage, see the teacher cover letter examples, and for the primary grades the elementary school teacher cover letter.

Before you send it

The letter that works is short, specific and written for one employer. It leads with something you did, names something real about them, proves one claim and asks for a conversation. The greeting, the font and the sign-off all matter far less than whether the first two lines gave a busy reader a reason to keep going. For a role where that matters every day, the medical assistant cover letter examples show it in three finished letters. For finished letters by role, see the computer science cover letter examples for students and new graduates, or the custodian cover letter examples for school and facilities jobs.
