What a Cover Letter Does

Your resume lists facts. Your cover letter shows why those facts matter for this job.

It also shows your writing skills and interest in the company.

How to Write a Cover Letter Step by Step

1. Study the Job Post

Highlight the top three skills the employer wants. Plan to address each one.

2. Write a Strong Opening

Name the role and share one reason you are a great fit. Skip generic lines.

3. Show Your Results

Give two or three short examples with numbers when you can. Show how you helped past teams.

4. Connect to the Company

Mention something specific you admire about the company. It shows you did your homework.

5. Close With Confidence

Thank the reader and say you would welcome an interview.

Mistakes to Avoid

Do not repeat your resume line by line. Add context and stories instead.

Avoid one letter for every job. Tailor each one to the role.

Skip long paragraphs. Short blocks are easier to read.

Final Checks

Read your letter out loud to catch awkward phrases.

Check the company name and hiring manager’s name twice. Small errors stand out.

Save it as a file type the employer asks for.

Research the Company First

A tailored letter beats a generic one every time. Spend 15 minutes learning about the company before you write.

Read the company website, recent news and the job post. Note its mission, products and any recent wins.

Mention one detail that shows you did your homework. For example, connect your skills to a new project the company launched.

CareerOneStop, sponsored by the United States Department of Labor, offers free job search tools and guides. It can help you learn more about employers and roles.

Match Your Skills to the Job Post

Employers want proof that you can do the job. Pick the top three skills from the listing and match each one to your experience.

Not sure which skills matter most in your field? Check the Occupational Outlook Handbook from the Bureau of Labor Statistics (BLS). It describes typical duties for hundreds of jobs.

Use the same key words the employer uses. Many companies scan letters with software before a person reads them.

Write a Strong Opening Line

Your first sentence decides whether the reader keeps going. Skip tired openers and get to the point.

Name the job title in the first paragraph. Recruiters often handle many openings at once.

Show Results With Numbers

Numbers make your claims believable. They also help your letter stand out from others.

Think about money saved, time saved or goals reached. Even small numbers, like “trained four new hires,” add weight.

If you do not have exact figures, use honest estimates. Words like “about” or “nearly” keep you truthful.

Tailor Without Starting Over

You do not need to write every letter from scratch. Build a basic template with your strongest stories.

For each new job, change the opening, the company details and the skills paragraph. Keep your closing and contact details the same.

Save each version with the company name in the file name. This makes it easy to review before an interview.

Use Writing Tools Wisely

Chatbots can help you brainstorm and fix awkward sentences. They work best as an editor, not as the main writer.

Give the tool your real experience and ask for a cleaner version. Then rewrite parts so it sounds like you.

Check every claim the tool adds. Never include skills or results you do not truly have.

Tips for Career Changers

Changing fields can feel tricky on paper. Your cover letter is the best place to explain the switch.

Focus on transferable skills like communication, problem solving and leadership. Show how they apply to the new role.

Mention any classes, certificates or volunteer work in the new field. These show real commitment.

Send It the Right Way

Follow the employer’s instructions exactly. Some want an upload, while others want the letter in the email body.

Save uploads as a Portable Document Format (PDF) file so the format stays the same on every device. Name the file with your full name and “Cover Letter.”

If you email it, write a clear subject line with the job title. Keep the email body short and polite.

Watch for Job Scams

Fake job offers are common online. Be careful if an employer asks for money, gift cards or banking details early on.

The Federal Trade Commission (FTC) explains how to spot a job scam. You can report suspicious offers at ReportFraud.ftc.gov.

A Simple Cover Letter Checklist

Run through this list before you hit send. It takes two minutes and can catch costly mistakes.

• The company name and job title are correct.
• The letter fits on one page.
• Each paragraph has a clear point.
• You included at least one result with a number.
• Your contact details are up to date.
• You read it out loud once.

Ask a friend to read it too. A fresh pair of eyes catches typos you might miss.

Follow Up After You Apply

A polite follow-up can keep your name in mind. Wait about one week after you apply.

Send a short email to the recruiter or hiring manager. Restate your interest and mention one key skill.

Keep it brief and friendly. One follow-up is enough unless they ask you to check back.

How Long Should a Cover Letter Be?

Most cover letters work best at three or four short paragraphs. Aim for about 250 to 400 words.

Hiring managers often skim dozens of letters in one sitting. A tight letter shows respect for their time.

If you go over one page, cut the weakest example. Keep only the stories that match the job most closely.

Use a clean, simple font in a readable size. Leave white space between paragraphs so the page breathes.

Cover Letter Mistakes to Avoid

Small mistakes can weaken a strong cover letter. Watch out for these common problems.

• Using the same letter for every job
• Repeating your resume word for word
• Writing more than one page
• Forgetting the hiring manager’s name when it is listed

Tailor each letter to the job and company. Mention one or two skills that match the role.

Make Your Letter Easy to Read

Hiring managers read many letters. A clear format helps yours stand out.

Use short paragraphs and a simple font. Keep the tone friendly and professional.

Proofread Before You Send

Read your letter out loud to catch mistakes. Ask a friend to check it too.

Save each letter with your name and the company name in the file title.
