The cover letter’s relevance has been hotly debated in the jobs and careers industry. At JobHero, we know that many job seekers feel that submitting a cover letter can be yet another time-consuming task in an already overwhelming job application process. 

However, you shouldn’t discount the influence a cover letter can have in convincing employers you deserve the job. To help you take advantage of all the job search tools at your disposal, we’ve created this guide to show you the value of a cover letter and what it consists of. We’ll also share some writing tips that’ll help you land an interview. Ready? Let’s start.

What Is a Cover Letter?

A cover letter is a formal one-page document that has become a standard item—along with your resume—in most job application processes. Although usually regarded as optional by recruiters, in many cases it’s a strict requirement to get a job.

What is the point of a cover letter?

If you’re asking yourself “Do I really need a cover letter?”, you’re likely considering whether the effort to write one is worth the potential benefits. 

A cover letter helps you elaborate on the accomplishments stated in your resume. Although some job applications don’t require a cover letter, we always recommend including one so you can explain your key strengths, interest in the job opening, or passion for the employer’s goals. 

Your cover letter can also delve into the personal reasons why you want to work for this employer. Genuine interest can help sway a hiring manager’s decision to interview you. 

Feel more convinced now? If you’ve decided that a cover letter is right for you, we’ve got a professional Cover Letter Builder that can drastically cut back the time it takes to write a cover letter. Simply type in your target job title and watch the builder generate a personalized letter in minutes.

Different types of cover letters

Although this article focuses mainly on answering the question, “What is a cover letter for a resume?”, you’ll probably have opportunities to write other formal messages during your career. Here’s a list of different types of cover letters:

  • Letter of application: A cover letter is a type of application letter. Other letters of application relate to college, grant, or fellowship applications.
  • Letter of intent: Unlike a cover letter, which you submit along with your resume for a job opening, a letter of intent is a formal letter to introduce yourself to an employer not actively hiring.  
  • Letter of interest: Use a letter of interest to request a job shadowing opportunity or an informational interview.
  • Reference letter: Unlike a cover letter highlighting your qualifications, a reference letter vouches for another person’s qualifications and professional character.  
  • Resignation letter: A resignation letter informs your current employer of your decision to leave a job and your last working date. A well-written letter can help you maintain positive working relationships with previous employers.
  • Job acceptance letter: Once you land a job offer, a job acceptance letter lets you formally accept the position, confirm key details like your start date, and express enthusiasm for the role—setting a positive tone before your first day.

How Do You Format a Cover Letter?

Knowing how to format each part of your cover letter ensures it looks professional, is easy to read, and makes a strong first impression. Let’s walk through the main parts of your cover letter.

1. Contact information

At the top of the page, add your contact information, date of writing, and employer’s professional contact information. Your contact information should include your first and last name, phone number, professional email address, and city and state location for you and the employer.

Example:

Sarah Goodman
New York, NY
555-555-5555
sarah.goodman@email.com

Oct. 1, 2024

Matt James
Head of Communications
NBC
1422 86th Ave.
New York, NY 33992
333-333-3333
matt.james@nbc.com

2. Greeting and introduction

Open your cover letter with a personalized greeting. Avoid impersonal greetings like “To whom it may concern.” This overused opening gives your cover letter a disinterested and generic vibe that hiring managers can find off-putting. 

Follow this greeting with an introduction that references the open job title, your relevant work experience, and up to three relevant skills, along with short examples.

Example:

As a seasoned social media marketer with three years of experience, I am eager to join your team as your new social media manager. I created a digital campaign to build brand awareness, increasing my company’s social engagement and interactions by 30% in two months. With my consumer analysis, marketing skills, and attention to detail, I aim to bring similar value to your workplace.

3. Body paragraphs

Describe your most marketable skills and achievements in one to two paragraphs, and explain how you meet the company’s demands. When describing your past accomplishments, use numbers and data to demonstrate quantifiable results! 

Visit our library to see additional cover letter examples.

Example:

I am a resourceful TV producer with an impeccable reputation for delivering projects on time and within budget. With meticulous planning and incredible results, I have successfully created projects that have surpassed the goal by 20%.

4. Conclusion and sign-off

Close your cover letter with gratitude. Thank the hiring manager for their time, and share your interview availability. This information acts like a call to action, making it easier for hiring managers to schedule a follow-up interview.

Example:

Thank you for your time and consideration. To demonstrate the scope of my career history and professional competencies, please take a moment to review my attached resume for this role. I am thrilled about this opportunity and look forward to discussing my qualifications. 

Kind regards,

Sarah Goodman

What makes a good cover letter stand out?

A strong cover letter doesn’t just repeat your resume; it highlights your best selling points and shows why you’re a perfect match for the role. To make yours stand out from the stack, focus on adding these key elements:

  • Explain your interest: Since you’re potentially joining an existing team of workers, employers want a cultural fit and a qualified employee. 
  • Match the job description: Carefully read the job advertisement and find matching experience from your professional history. Sharing this information can compel hiring managers to give your application more than a cursory glance because they can see your transferable skill set
  • Be focused: Hiring managers may need to sort through hundreds of applications, so write a carefully tailored and brief cover letter to maximize their limited attention. Keep your cover letter to one page and under 400 words. Use targeted work history examples and avoid a generic template.
  • Include references when requested: Hiring managers often trust referrals from current employees, so if someone at the company recommended you, mention their name in the opening paragraph of your cover letter. If the employer specifically requests a personal reference with contact details, you can include it in your cover letter, resume, or ideally, in a separate document. Be sure to obtain your colleague’s permission before sharing their information.

Cover Letter Mistakes to Avoid

Even the best-written cover letter can fall flat if it includes common errors that turn off employers. Avoid these common cover letter mistakes to ensure your application gets noticed for the right reasons:

1Using a generic template

Hiring managers can spot a copy-paste cover letter instantly. Always customize your letter for each job by mentioning the company name, the role, and how your experience aligns with their needs. Browse some of our best cover letter templates for more formatting ideas and inspiration.

2Repeating your entire resume

Your cover letter should complement, not duplicate, your resume. Instead of listing every job duty again, expand upon one or two relevant achievements that prove you’re the right fit.

3Using an impersonal greeting

Open your letter with a specific name whenever possible. “To whom it may concern” feels cold and outdated. If you can’t find a name, try “Dear [Department] Hiring Team”, instead.

4Being too vague or wordy

A good cover letter is clear and concise. Avoid filler phrases like “I’m a hard worker” without showing evidence. Back up your claims with real examples and measurable results.

5Forgetting to proofread

Typos, grammar mistakes, or the wrong company name can instantly disqualify you. Read your cover letter out loud and run it through spellcheck before sending.

6Leaving out a call to action

Wrap up your cover letter by thanking the reader for their time and suggesting next steps. Make it easy for the employer to reach out by sharing your availability or best contact method.

Key Takeaways

As you embark on your job search, keep the following cover letter tips in mind:

  • Your cover letter is a supplemental document that supports your resume. Never repeat what’s on your resume, but expand and explain one or two key points. 
  • A standard cover letter includes four sections: contact information, a greeting and introduction, body paragraphs detailing key skills or achievements, and a conclusion with a call to action for an interview.
  • Express genuine interest in the company and address the job description needs.
  • If requested by the employer, add a trusted reference to increase credibility with hiring managers.
