What Is an Application Cover Letter? Complete Guide with Examples
TL;DR - Quick Answer
An application cover letter is a one-page document that accompanies your resume when applying for a job, introducing yourself to the employer and explaining why you're the ideal candidate for the position. Unlike a resume which lists your qualifications in bullet points, a cover letter tells your professional story, demonstrates your enthusiasm for the role, and connects your experience to the specific needs of the employer. It's your opportunity to make a personal first impression and show the hiring manager why they should read your resume.
Think of your cover letter as a bridge between your resume and the job description—it explains how your background makes you uniquely qualified for this specific opportunity at this specific company.
Key Takeaways
A cover letter is a personalized introduction: It complements your resume by adding context, personality, and specific reasons why you want this particular job.
It's typically one page: Most cover letters are 250-400 words, fitting on a single page with proper formatting.
Customization is essential: Generic cover letters are easy to spot and often rejected. Each letter should be tailored to the specific job and company.
It serves multiple purposes: Beyond introducing yourself, it demonstrates writing skills, shows research about the company, and expresses genuine interest.
Many employers still require them: Despite debates about their relevance, 83% of hiring managers say cover letters are important in their hiring decisions.
What Is an Application Cover Letter? A Complete Definition
An application cover letter—also known simply as a cover letter, covering letter, or letter of application—is a formal document that you submit alongside your resume when applying for a job. It serves as your personal introduction to the hiring manager and provides context that your resume alone cannot convey.
While your resume presents your qualifications in a structured, bullet-point format, your cover letter tells the story behind those qualifications. It answers the critical question every hiring manager asks: "Why should I interview this person for this job at our company?"
The term "cover letter" comes from the traditional practice of placing a letter on top of ("covering") your resume when mailing job applications. Today, even though most applications are submitted electronically, the cover letter remains a crucial component of the job application process.

Cover Letter vs. Resume: Understanding the Difference
Many job seekers confuse cover letters and resumes or wonder why both are necessary. Understanding the distinction is essential for creating effective application materials.
Key Differences at a Glance
Aspect | Cover Letter | Resume |
|---|---|---|
Format | Narrative paragraphs | Bullet points and sections |
Length | One page (250-400 words) | One to two pages |
Purpose | Introduce yourself, explain fit, show enthusiasm | List qualifications, experience, and skills |
Customization | Must be tailored to each job | Can be slightly modified for different roles |
Tone | Conversational and personal | Formal and factual |
Content Focus | Why you want this job and why you're a fit | What you've done and what you can do |
Stories | Can include brief narratives | Achievement-focused bullet points |
Why You Need Both
Your resume is your professional fact sheet—it tells employers what you've accomplished. Your cover letter explains why those accomplishments matter for the specific role you're applying for. Together, they create a complete picture of your candidacy.
Consider this analogy: if your resume is a movie trailer showing highlights of your career, your cover letter is the director's commentary explaining the significance of those scenes and why they make you perfect for the role.
The Purpose of an Application Cover Letter
Understanding what is the purpose of a cover letter helps you write more effective ones. A cover letter serves several critical functions:
1. Personal Introduction
Your cover letter introduces you as a person, not just a list of qualifications. It allows you to express your personality, communication style, and enthusiasm in ways that a resume format doesn't permit.
2. Demonstrating Fit
The cover letter explains why you're specifically interested in this role at this company—not just any job. It connects the dots between your experience and the employer's needs, showing you've thought carefully about how you can contribute.
3. Addressing Potential Concerns
If you have gaps in employment, are changing careers, or are relocating, the cover letter provides space to proactively address these issues. It's your chance to reframe potential weaknesses as strengths. For career changers, see our guide on how to write a cover letter for a career change.
4. Showcasing Writing Skills
For roles requiring strong communication, your cover letter serves as a writing sample. A well-crafted letter demonstrates your ability to communicate clearly and persuasively—skills valued in virtually every profession.
5. Standing Out from Competition
In a stack of applications with similar qualifications, a compelling cover letter can be the factor that moves you to the interview pile. It's your opportunity to be memorable in a sea of similar resumes.
6. Expressing Genuine Interest
Hiring managers want candidates who genuinely want the job, not just anyone looking for a paycheck. A thoughtful cover letter that references specific aspects of the company and role demonstrates that you've done your research and are truly interested.
Types of Application Cover Letters
Not all cover letters serve the same purpose. Understanding the different types helps you choose the right approach for your situation.
1. Application Cover Letter (Standard)
This is the most common type—a letter written in response to a specific job posting. It directly addresses the requirements listed in the job description and explains how your qualifications match.
When to use: When responding to a job advertisement or online posting.
2. Prospecting Cover Letter (Cold Contact)
Also called an "uninvited" cover letter, this type is sent to companies that haven't advertised open positions. You're expressing interest in working for them and asking them to consider you for current or future opportunities.
When to use: When you're interested in a company that isn't actively hiring or when you want to get on their radar.
3. Networking Cover Letter
This letter is sent when someone in your network has referred you to a job or company. It references the mutual connection and leverages that relationship to establish credibility.
When to use: When a friend, colleague, or professional contact has referred you or suggested you apply.
4. Referral Cover Letter
Similar to a networking letter, but specifically when an employee of the company has directly referred you. These letters often carry more weight because employee referrals are highly valued by companies.
When to use: When a current employee has recommended you for a position.
Cover Letter Types Comparison
Type | Situation | Key Focus | Success Rate |
|---|---|---|---|
Application (Standard) | Responding to job posting | Match qualifications to requirements | Moderate |
Prospecting | No active job posting | Create interest in your candidacy | Lower (but less competition) |
Networking | Have a mutual connection | Leverage relationship and fit | Higher |
Referral | Referred by employee | Capitalize on internal recommendation | Highest |
What to Include in an Application Cover Letter
A well-structured cover letter includes specific elements that work together to create a compelling case for your candidacy. For a detailed breakdown, see our guide on what to include in a cover letter.
Essential Elements
Header: Your contact information, date, and employer's information (for formal printed letters)
Salutation: Professional greeting addressed to the hiring manager by name when possible
Opening paragraph: Hook that captures attention, states the position you're applying for, and introduces your value proposition
Body paragraphs: Evidence of your qualifications, relevant achievements, and connection to the company's needs
Closing paragraph: Call-to-action, expression of enthusiasm, and thank you
Sign-off: Professional closing ("Sincerely," "Best regards") followed by your name
Content Breakdown by Section
Section | Purpose | Length | Key Elements |
|---|---|---|---|

Closing | Motivate next steps | 2-3 sentences | Call-to-action, gratitude, enthusiasm |
How to Structure an Application Cover Letter
The structure of your cover letter directly impacts its effectiveness. A well-organized letter guides the reader through your argument for why you should be hired. For more details, see how to structure a cover letter.
The Classic Three-Part Structure
Part 1: The Hook (Opening Paragraph) — Grab attention immediately. State the position you're applying for and deliver your strongest selling point in 2-3 sentences. Avoid generic openings like "I am writing to apply for...". Instead, lead with an accomplishment or specific enthusiasm for the company.
Part 2: The Evidence (Body Paragraphs) — This is the meat of your letter. Use 1-2 paragraphs to provide specific examples of your relevant experience. Quantify achievements when possible. Connect your background to the specific needs mentioned in the job description.
Part 3: The Close (Closing Paragraph) — End with confidence. Express enthusiasm for the opportunity, thank them for their consideration, and include a clear call-to-action. Learn more about strong closings in our guide on how to end a cover letter.
Paragraph Structure Example
Opening: "When I increased customer retention by 34% at ABC Company using the same CRM system you're implementing, I knew my next step had to be a company as committed to customer success as XYZ Corp."
Body: "In my current role as Customer Success Manager, I've reduced churn by developing personalized onboarding sequences that address customer pain points in the first 30 days. I also built a feedback loop system that identified at-risk accounts 60 days before cancellation, allowing proactive intervention. These initiatives directly align with your stated goal of becoming the industry leader in customer satisfaction."
Close: "I'm excited about the opportunity to bring my customer-first approach to XYZ Corp's growth stage. I'd welcome the chance to discuss how my experience can support your retention goals. Thank you for considering my application."
Formatting Your Application Cover Letter
Proper formatting ensures your cover letter is professional, readable, and ATS-friendly. For comprehensive formatting guidelines, see how to format a cover letter.
Standard Formatting Guidelines
Length: One page maximum, typically 250-400 words. See how long should a cover letter be for more details.
Font: Professional fonts like Arial, Calibri, Times New Roman, or Georgia. Size 10-12 point. See what font to use for cover letter.
Margins: 1-inch margins on all sides (standard)
Spacing: Single-spaced with a blank line between paragraphs. See what spacing should a cover letter be.
Alignment: Left-aligned (standard business format)
File format: PDF preferred to preserve formatting, unless employer specifies otherwise
Professional Appearance Tips
Match your cover letter formatting to your resume for a cohesive application package
Use consistent header design between documents
Avoid excessive formatting (bold, italics, colors) that can appear unprofessional
Ensure adequate white space for readability
Proofread carefully—formatting errors suggest carelessness
How to Address Your Application Cover Letter
The greeting sets the tone for your entire letter. Getting it right shows attention to detail and respect for the recipient.
Best Practices for Addressing
Use the hiring manager's name: "Dear Ms. Johnson," or "Dear David Chen," is always preferable. Research the company website, LinkedIn, or call to ask.
When you can't find a name: "Dear Hiring Manager," or "Dear [Department] Team," are acceptable alternatives. See how to address a cover letter without a name for more options.
Avoid outdated greetings: "To Whom It May Concern" is considered outdated. "Dear Sir or Madam" can also feel impersonal.
Match formality to company culture: "Dear Hiring Team," works for casual startups; "Dear Ms. [Last Name]," is better for traditional industries.
Salutation Guide by Situation
Situation | Recommended Salutation | Notes |
|---|---|---|
Know the hiring manager's name | Dear Ms./Mr. [Last Name], | Most professional and personal |
Know first name, casual company | Dear [First Name], | Appropriate for startups/creative fields |
Don't know the name | Dear Hiring Manager, | Safe, professional default |
Applying to a team | Dear [Team Name] Team, | e.g., "Dear Marketing Team," |
Multiple interviewers | Dear Hiring Committee, | For formal panel situations |
Cover Letter Do's and Don'ts
Knowing what works and what doesn't can mean the difference between landing an interview and being passed over. Understanding what makes a good cover letter is essential for success.
Do's: Best Practices
Do customize each letter: Tailor your cover letter to the specific job and company. Reference the job title and company name.
Do lead with your strongest point: Put your most compelling qualification or achievement in the opening paragraph.
Do quantify achievements: Use numbers, percentages, and specific results whenever possible. "Increased sales by 40%" is stronger than "increased sales."
Do research the company: Reference specific initiatives, values, or recent news that show you understand the organization.
Do address the job requirements: Connect your experience to the specific qualifications listed in the job posting.
Do show enthusiasm: Express genuine interest in the role and company without being excessive.
Do proofread thoroughly: Check for typos, grammatical errors, and formatting issues multiple times.
Do include a call-to-action: End with a clear statement about wanting to discuss the opportunity further.
Don'ts: Common Mistakes
Don't use a generic template: Hiring managers can spot copy-paste letters instantly. They suggest you don't care about this specific job.
Don't repeat your resume: Your cover letter should add new information and context, not simply summarize what's in your resume.
Don't focus only on yourself: Balance what you want with what you can offer. The letter should address the employer's needs.
Don't make it too long: Hiring managers are busy. Keep it to one page—ideally 250-400 words.
Don't use clichés: Phrases like "I'm a team player" or "I think outside the box" are overused and meaningless without evidence.
Don't apologize for lacking experience: Focus on what you do have, not what you don't. Never draw attention to weaknesses.
Don't use unprofessional email addresses: partyanimal@email.com won't make a good impression.
Don't forget to attach it: Double-check that you've included your cover letter before hitting send.

Expert Insights on Application Cover Letters
"A cover letter is your opportunity to tell a story that your resume simply can't convey. It's where you explain not just what you've done, but why you did it, what you learned, and how it prepares you for this specific role. The candidates who understand this write letters that make me excited to meet them."
— Lily Zhang, Career Counselor at MIT and Career Expert at The Muse
This insight underscores the power of storytelling in cover letters. While resumes focus on achievements, cover letters reveal the person behind those achievements—their motivations, their thought process, and their genuine interest in the opportunity.
Frequently Asked Questions About Application Cover Letters
Is a cover letter the same as a letter of application?
Yes, the terms are often used interchangeably. A "letter of application," "application letter," "covering letter," and "cover letter" all refer to the same document—a one-page letter that accompanies your resume when applying for a job.
Do I always need a cover letter?
Unless the job posting specifically says "no cover letter," you should include one. Even when it's listed as "optional," submitting a well-crafted cover letter demonstrates extra effort and genuine interest. For more on this, see should I write a cover letter for every job.
How long should an application cover letter be?
Most cover letters should be one page, typically 250-400 words. Hiring managers are busy and appreciate concise communication. Focus on quality over quantity—every sentence should add value.
Should I write a different cover letter for each job?
Yes. Each cover letter should be customized to the specific job and company. While you can use a similar structure and adapt certain paragraphs, the content should be tailored to match the job requirements and reflect genuine interest in that particular opportunity.
What's the difference between a cover letter and a personal statement?
A cover letter is written for a specific job application and focuses on why you're qualified for that particular role. A personal statement (often used in academic or graduate school applications) is broader, discussing your background, interests, and goals without targeting a specific position.
Can I use the same cover letter for different positions at the same company?
No. Different positions have different requirements, and your cover letter should address those specific requirements. Even at the same company, each role may report to different managers and require different skills. Customize each letter accordingly.
How do I send a cover letter with an online application?
Most online application systems have a specific field for uploading cover letters. If not, you can often combine your cover letter and resume into a single PDF. Some systems also allow you to paste your cover letter into a text field. When emailing directly, see our guide on how to email a resume and cover letter.
What if I'm applying for a job internally?
Internal applications still benefit from cover letters, though the tone may be slightly different. Reference your existing relationship with the company, your understanding of its culture, and how your internal experience prepares you for the new role.
Should I include my salary expectations in a cover letter?
Only if the job posting specifically asks for salary requirements. Otherwise, save salary discussions for later in the hiring process after you've had a chance to demonstrate your value.
How do I handle employment gaps in a cover letter?
Address gaps briefly and positively. Focus on what you did during that time (learning new skills, volunteering, caregiving) and emphasize that you're now ready and excited to contribute. Don't over-explain or apologize.
What if I'm overqualified for the position?
Address it directly but positively. Explain why you're genuinely interested in this role specifically—perhaps it offers growth in a new direction, work-life balance, or alignment with your values. Show that you understand the role and are committed to it.
Do remote jobs require cover letters?
Yes, and they're often even more important for remote positions. Employers want to see that you can communicate effectively in writing, are self-motivated, and understand the demands of remote work. See our remote job cover letter example for guidance.

Conclusion: Your Cover Letter Is Your First Impression
An application cover letter is more than just a formality—it's your opportunity to make a compelling case for why you deserve an interview. While your resume lists your qualifications, your cover letter brings those qualifications to life, showing how they apply to the specific role you're pursuing.
The most effective cover letters:
Tell a story that connects your experience to the job requirements
Demonstrate genuine interest in the specific company and role
Quantify achievements to prove your impact
Show personality while maintaining professionalism
Include a clear call-to-action that invites next steps
Remember that every cover letter should answer three questions: Why this company? Why this role? Why you? When you can answer these questions clearly and compellingly, you've created a letter that works.
Whether you're applying for your first job or making a strategic career move, investing time in your cover letter pays dividends. In a competitive job market, it's often the detail that sets candidates apart.
