Nobody sits down excited to write a cover letter. You stare at a blank page, type "I am writing to apply for..." and delete it three times, and twenty minutes later you have a polite paragraph that says almost nothing about why you should get the job. The good news: a cover letter is not a writing contest. It has one job — make the person hiring want to read your resume properly instead of skimming past it.
That job is smaller than you think. You do not need your life story or fancy language. You need to show, quickly, that you understand what this company needs, that you have done similar work before, and that you would be easy to hire. One page. A few honest paragraphs.
This guide walks through how to write a cover letter step by step, with full examples you can borrow the shape of — the structure that works, how long it should be, how to tailor it to each job post, and the mistakes that quietly get letters tossed aside.
The uncomfortable truth: recruiters skim
Let's be honest about the other side of the desk. A hiring manager with 80 applications is not reading every letter slowly with a cup of coffee. You may only get a quick scan — sometimes 30 seconds, sometimes less on the first pass — before they decide whether your resume deserves a closer look. People online love to quote exact numbers for that scan, but the precise figure does not matter. What matters is what it means for how you write.
Write for a scan, not a book club. Your best point cannot be buried in paragraph three. Short paragraphs help, because a wall of text gets skipped. If a tired person at 4 p.m. can follow your letter in one pass and remember one strong fact about you, you have done your job.
Stop worrying about sounding impressive and start worrying about sounding specific. "I am a hardworking, motivated team player" could describe anyone applying for any job. One concrete detail — a number, a system you know, a result you delivered — beats a paragraph of adjectives. Specific is memorable. Generic is invisible.
The 4-part structure that actually works
Almost every good cover letter follows the same shape: four parts. Once you know it, you are never starting from a blank page — you are filling in four boxes with your own details.
1. The header and greeting
At the top, put your name, phone number, email, and city. You do not need your full street address; nobody is mailing you a reply. Add the date and, if you know it, the hiring manager's name. If you can find a name — from the job post, the company website, or LinkedIn — use it. "Dear Ms. Carter," beats everything else.
If you truly cannot find a name, use "Dear Hiring Manager" or "Dear Customer Service Team." Do not use "To Whom It May Concern." It sounds cold and dated, like a letter that could have been sent to any company on earth. Which, to be fair, is exactly what it usually is.
2. The opening hook
Your first paragraph has maybe three sentences to earn the rest of the letter. Do not waste them announcing that you saw the job and would like to apply — they know that. Lead with your strongest match for this exact role: relevant experience, a result you are proud of, or something specific you noticed about the company.
Mentioning the company by name and tying yourself to something real about it — a new location, a product line, a problem the job post describes — tells the reader this letter was written for them. It takes two extra minutes on their website, and hiring managers can spot a copy-and-paste letter in five seconds. They read dozens a week.
Compare these two openings for the same person applying for the same job. The facts are identical. The effect is not.
Dear Hiring Manager, I am writing to apply for the Warehouse Supervisor position I saw advertised online. I have experience working in warehouses and I believe I would be a great fit for your company. I am a hard worker and a team player, and I would love the opportunity to join your team.
Dear Mr. Alvarez, When your Riverside distribution center added a second shift last spring, keeping pick accuracy up with a brand-new crew was probably the hard part — it was the exact problem I was hired to solve in my last role. Over the past four years as a warehouse lead at a regional food distributor, I trained 14 new pickers and helped cut picking errors from 3.1% to 1.4% in six months, while our small team shipped around 900 orders a day. I would like to bring that same steady, numbers-first approach to your supervisor opening.
See what changed? The strong version names the manager, shows Daniel knows something about this workplace, and puts a real result in the second sentence. Daniel sounds like a person, not a template.
3. The proof paragraph
This is the heart of the letter, and the part most people get wrong by repeating their resume in sentence form. Pick one or two of the strongest matches between your past work and this job post, and tell them as short stories with outcomes: what was the situation, what did you do, and what changed?
Numbers make proof believable, and they do not have to be huge. Tickets closed per day, time cut, errors reduced — ordinary numbers count, as long as they are true. If you do not track exact figures, use an honest estimate and say "around" or "roughly." Never invent a number you cannot explain in an interview.
Here is a proof paragraph from a different field, so you can see the shape holds up anywhere.
In my current support role at a small software company, I handle about 45 tickets a day across email and live chat. Last year I noticed the same billing question kept landing in our queue, so I wrote a short help article and a set of saved replies for the team. That one question dropped by roughly a third within two months, my customer satisfaction score stayed at 96% across the year, and I ended up training our three newest hires on the trickier account cases — the part of the job I enjoy most.
That paragraph does a lot in five sentences: volume, initiative, a measurable result, a quality score, and a hint this person is trusted to train others. A manager skimming it already has interview questions. That is what proof is supposed to do.
4. The close with a call to action
End short and confident. Thank them in one sentence, restate your interest in this role in one more, and ask for the next step plainly: "I would welcome the chance to talk through how my experience could help your team hit its spring targets. I am available for an interview at your convenience." Then sign off simply — "Sincerely" or "Best regards" and your name. Skip the gushing gratitude, and definitely skip apologizing for anything.

Build my cover letterHow long should a cover letter be?
One page. Roughly 250 to 400 words. Some applicants send 90 words, which reads like they could not be bothered. Others send two dense pages that read like a memoir, which nobody finishes. Somewhere between a postcard and a biography sits the letter that gets read.
Think three to four paragraphs, each three to five sentences. If yours runs long, the fix is not smaller font — please don't — it is cutting the weakest story. If it runs short, you probably skipped the proof paragraph, the one part you cannot afford to skip.
Tailor it to the job post, every single time
Here is the step people skip because it sounds like extra work, and it is the step that matters most. The job post is basically a cheat sheet: it tells you the problems the company wants solved, the tools they use, and the words they use for all of it. Mirror that language back — naturally, not by stuffing keywords into every line.
A simple routine keeps this fast. Highlight the three requirements that come up most or sit at the top of the post. Make sure each one appears in your letter with a line of proof attached. If the post says "experience with inventory counts" and you have done cycle counts for two years, say exactly that, in those words. If it asks for someone who can "de-escalate frustrated customers," use that phrase and back it with an example.
It helps with screening software too: many larger employers scan applications for matches with the job description before a person ever looks. Honest language that echoes the post works for both. Copying the whole post into your letter in white text does not — people check, and it ends applications.
Ten tailored applications will almost always beat fifty identical ones. Each one actually argues for that job instead of just announcing that you exist.
The mistakes that get letters binned
Rehashing your resume is the biggest one. A letter that reads "From 2019 to 2022 I worked at... then from 2022 I worked at..." has wasted its page — that timeline is already on the next page, cleaner. Use the letter for the why and the proof.
Typos come next. It is hard to believe someone is "detail-oriented" when the company name is misspelled in paragraph one. Read your letter out loud once — your ear catches things your eyes skip — and check names and titles character by character.
Generic flattery is another quiet killer. "Your company is a world-class leader in innovation and excellence" just fills space. Replace praise with knowledge: name the project or the expansion. One real observation beats five compliments.
Finally, never apologise for what you lack. "Although I don't have much experience..." points a flashlight at your weakest spot. Lead with what transfers instead: the closest work you have done and what it taught you.
A simple way to write your next one
If the blank page still feels heavy, try this order. Highlight the post's top three requirements. Next to each, jot the truest example you have, with a number if you can. Write your opening using the best example, your proof paragraph using the other two, and close in three sentences. About twenty focused minutes, done.
Step away for ten minutes, read it fresh, and cut any sentence that could appear in anyone else's letter. A good letter will not get you the job on its own, but it can get your resume the proper reading it deserves.

Create my cover letter freeFrequently asked questions
How long should a cover letter be?
One page, roughly 250 to 400 words, in three to four short paragraphs. Long enough for one or two real examples with numbers, short enough to read in one pass. If it runs longer, cut the weakest example rather than shrinking the font.
What should I include in a cover letter?
Your contact details, a greeting to a named person if you can find one, an opening leading with your strongest match, a proof paragraph with a real achievement, and a short close that asks for an interview.
Do I need a cover letter if the job post says optional?
Usually, yes, if there is a place to attach it. Many applicants skip an optional letter, so a short, tailored one is an easy way to stand out — as long as it adds proof your resume alone doesn't show.
Can I use the same cover letter for every job?
Reuse the structure and your best examples, but change the opening, company details, and highlighted skills for each post. A fully identical letter sent everywhere is easy to spot and easy to skip.
Should I write my cover letter from scratch or use a generator?
Either works, as long as the final letter sounds like you and names specifics from the job post. A generator gets you the structure and a solid first draft fast — then personalize the opening and proof paragraph.
