How to Write a Cover Letter: Complete Guide

A strong cover letter can instantly elevate your job application—especially when employers review hundreds of resumes daily. This guide walks you through every step of writing a professional, personalized, and compelling cover letter. You’ll learn how to structure your letter, highlight achievements, tailor your message to each job, and present yourself as the strongest candidate.

Understand the Purpose of a Cover Letter

Before you start writing, it’s crucial to understand why a cover letter matters.

A strong cover letter should:

  • Introduce who you are in a professional, concise way
  • Explain why you’re a strong fit for the role
  • Demonstrate that you understand the company’s needs and culture
  • Highlight one to three key achievements (not your entire resume)
  • Show personality, motivation, and communication skills
  • Encourage the hiring manager to continue to your resume
  • Differentiate you from other applicants who submit generic letters

Think of your cover letter as a bridge between the job description and your resume — it brings your experience to life and tells the story behind your skills.

If your resume is the "what," then your cover letter is the "why."

Follow the Standard Cover Letter Format

Hiring managers expect a clean, professional format. A proper cover letter includes:

  • Header — your contact details
  • Greeting — personalized whenever possible
  • Opening paragraph — strong hook showing relevance
  • Body paragraphs — achievements + company alignment
  • Closing paragraph — call to action
  • Signature — your full name and links

Length: 250–400 words (never exceed one page)

Tone: Professional, confident, and conversational — not robotic or overly formal.

Structure Example:

  • 1 paragraph opening
  • 1–2 paragraphs highlighting achievements
  • 1 paragraph closing

This layout ensures readability and keeps the flow smooth for busy recruiters.

Write a Professional Header

Your header should visually match your resume for consistent personal branding.
It must be clean, simple, and ATS-friendly.

Include:

  • Full name
  • Phone number
  • Professional email
  • City & state (optional)
  • LinkedIn profile (recommended)
  • Portfolio or website (if relevant)

Example Header:

Sarah Johnson
Austin, TX • sarah.johnson@gmail.com
 • (512) 222-8877
LinkedIn.com/in/sarahjohnson • sarahjohnsonportfolio.com

Tips:

  • Use the same fonts and formatting as your resume
  • Avoid adding photos or icons
  • Keep spacing consistent

A polished header immediately creates a strong first impression.

Use a Personalized Greeting

A generic greeting signals a generic application.

Whenever possible, address a real person.

Best options:

  • Dear Hiring Manager,
  • Dear [Company Name] Recruitment Team,
  • Dear [Hiring Manager’s Full Name], (best option)

If you cannot find a name after checking:

  • Company website
  • LinkedIn
  • Job post
  • Google search

…then “Dear Hiring Manager” is perfectly professional.

Avoid:

  • “To Whom It May Concern” (old-fashioned)
  • “Dear Sir/Madam” (not inclusive)

A personalized greeting shows effort—and recruiters notice it.

Craft a Strong Opening Paragraph

Your opening paragraph is your “make or break” moment.

A weak opening loses attention instantly; a strong one hooks the reader.

Your opening should:

  • Mention the job title
  • Show genuine enthusiasm
  • Highlight a key achievement or strength
  • Demonstrate understanding of the company

Weak Opening (generic):

“I am writing to apply for the Marketing Coordinator position at your company.”

Strong Opening (personalized + impactful):

“I’m thrilled to apply for the Marketing Coordinator role at SparkCV. With three years of experience boosting social media engagement and launching data-driven campaigns, I’m excited about contributing to your mission of helping job seekers build stronger careers.”

Write an Impactful Body Section (Achievements + Proof)

This is where you show measurable value. Employers want results, not job duties.

Use this proven formula: Action Verb + What You Did + Outcome

Example bullets you can use in the body section:

  • “Increased organic traffic by 58% by optimizing content strategy.”
  • “Managed a $200k annual advertising budget and reduced costs by 17%.”
  • “Improved customer satisfaction scores from 82% to 94% in six months.”

Also mention specific tools or skills you use:

  • HubSpot
  • Salesforce
  • Figma
  • Google Analytics
  • SQL
  • Asana
  • Adobe Creative Suite

Show the employer that you understand their needs.

Show That You Understand the Company

This is where most applicants fail.

Include:

  • Their mission
  • Their current challenges
  • A recent product launch
  • A value you share
  • A reason you’re genuinely excited

Example:

“I admire SparkCV’s commitment to simplifying the job search process through modern, user-focused tools. Your mission aligns closely with my passion for building accessible digital experiences.”

Even one sentence like this sets you apart.

Write a Strong Closing Paragraph

Your closing should:

  • Reinforce your enthusiasm
  • Re-state what you bring
  • Include a call-to-action
  • Thank the hiring manager

Example:

“Thank you for considering my application. I’d welcome the opportunity to discuss how my marketing background and results-driven approach can support your team’s goals. I look forward to the possibility of contributing to SparkCV.”

Sign Off Professionally

Avoid casual endings like “Cheers” or “Best.”

Use:

  • Sincerely,
  • Best regards,
  • Thank you,

Example:

Sincerely,
Sarah Johnson
