Do You Actually Need a Cover Letter in 2025?
The short answer: almost always yes.
Every few years, someone publishes an article declaring cover letters dead. And every year, hiring managers prove them wrong. A 2024 ResumeGo study found that applicants who included a tailored cover letter were 50% more likely to receive a callback than those who submitted a resume alone.
Here is when you definitely need one:
- The job posting asks for it. Skipping it signals you do not follow instructions — an immediate red flag.
- You are changing careers. Your resume cannot explain why a marketing manager is applying for a UX design role. Your cover letter can.
- You have employment gaps. A brief, confident explanation in a cover letter is far better than leaving the recruiter to guess.
- You are applying to a competitive role. When 200 candidates have similar qualifications, a cover letter is the only differentiator.
- You have a referral or connection. “Sarah Chen on your engineering team suggested I apply” belongs in a cover letter, not crammed into your resume header.
The only time you can safely skip a cover letter is when the application system literally has no field for one, or the posting explicitly says “do not include a cover letter.”
The Anatomy of a Great Cover Letter
Every effective cover letter follows the same five-part structure. Think of it like a persuasive argument — each section builds on the last to make a case for why you are the right person for this specific role.
The Header
Your name, contact details, date, and the recipient’s information. Keep it clean. Match the formatting of your resume so they look like a cohesive package. If you know the hiring manager’s name, use it. “Dear Ms. Hernandez” is always better than “Dear Hiring Manager.”
The Hook (Opening Paragraph)
You have one sentence to earn the next ten seconds of attention. Lead with your strongest credential, a specific result, or a genuine connection to the company. Never start with “I am writing to express my interest in...” — that is a guaranteed skim-and-skip.
The Evidence (Body Paragraphs)
One or two paragraphs with 2–3 specific achievements that directly map to the job requirements. Use numbers. “Grew organic traffic 140% in 8 months” beats “experienced in SEO” every time. This is where you prove you are not just qualified — you are exceptional.
The Connection (Why This Company)
Show you have done your homework. Reference something specific: a recent product launch, a company value you share, a market challenge they face. Generic flattery (“I admire your innovative culture”) reads as copy-paste. Specificity reads as genuine interest.
The Close (Call to Action)
End with confidence, not desperation. “I would welcome the chance to discuss how I can help your team achieve [specific goal]” is strong. “I hope to hear from you and thank you for your time and consideration” is forgettable. Be specific about what you want: a conversation, an interview, a call.
How to Write a Cover Letter: Step by Step
Step 1: Research the Company and Role
Before you type a single word, spend 15 minutes studying the job posting, the company’s website, and their recent news. Look for:
- The top 3 requirements in the job description (these become your talking points)
- The company’s mission, values, or recent achievements (these become your “why this company” paragraph)
- The hiring manager’s name (check LinkedIn or the company team page)
- Keywords and phrases used repeatedly in the posting (these should appear naturally in your letter)
Step 2: Write Your Opening Hook
Your first sentence is the most important. Here is the formula: lead with a result, credential, or connection — then tie it to what they need.
Notice the difference. The strong opening gives the hiring manager a reason to keep reading. The weak one gives them a reason to move on to the next application.
Step 3: Build Your Evidence Paragraphs
Pick 2–3 achievements from your career that directly address the role’s top requirements. For each achievement, use this structure:
- Situation: Briefly set the context (one sentence)
- Action: What you specifically did (one sentence)
- Result: The quantifiable outcome (the payoff)
This is the same STAR method you would use in interviews, compressed into tight prose. Do not just list duties. Show outcomes.
Step 4: Show Why This Company, Not Any Company
This is where most cover letters fail. Candidates write paragraphs that could apply to any company in the industry. Instead, reference something specific:
- “Your recent Series B funding and expansion into the European market is exactly the kind of growth challenge I thrive in.”
- “I have been a customer of [Product] since 2021, and I have strong opinions about how the onboarding flow could convert 20% more trial users.”
- “Your engineering blog post on migrating to microservices resonated with me because I led a similar migration at [Company].”
Specificity is the proof that you care about this role, not just any role.
Step 5: Close with Confidence
End on a forward-looking note. State what you want (an interview, a conversation) and what you will bring. Avoid thanking them excessively — you are not asking for a favor, you are proposing a mutually beneficial relationship.
Your cover letter won’t save a weak resume.
Before you spend time perfecting your cover letter, make sure your resume can actually pass ATS screening. Most cannot.

7 Cover Letter Mistakes That Kill Applications
Even candidates with strong qualifications sabotage themselves with these errors. Avoid all of them.
Restating your resume in paragraph form
Your cover letter should add new context, not repeat what the hiring manager can already see in your resume. Use it to explain the why behind your career moves and highlight achievements your resume format cannot do justice.
Using the same letter for every application
Hiring managers can spot a generic cover letter within three seconds. If you are not willing to customize it for the role, you are signaling that you do not care enough about the job. Tailor at least the opening hook and the “why this company” paragraph for every application.
Writing about what you want, not what you offer
“I am looking for an opportunity to grow my career in a dynamic environment” tells the employer nothing about what you bring to the table. Flip the script: every sentence should answer the question “What is in it for them?”
Opening with “To Whom It May Concern”
This greeting screams 1998. If you cannot find the hiring manager’s name, use “Dear [Department] Team” or “Dear Hiring Team.” Spend five minutes on LinkedIn before resorting to a generic salutation.
Making it longer than one page
Hiring managers spend 30 seconds on a cover letter. One page maximum. If you cannot make your case in 300 words, the problem is not the word limit — it is the editing. Cut filler phrases like “I believe that” and “I would like to” and get to the point.
Typos and grammatical errors
A typo on page two of a resume might be forgiven. A typo in a 300-word cover letter is devastating. It signals carelessness in a document that is supposed to demonstrate attention to detail. Read it aloud. Then read it aloud again. Then have someone else read it.
Being apologetic about gaps or weaknesses
“Although I lack direct experience in...” plants doubt before you have made your case. Instead of leading with what you are missing, lead with the transferable skills you bring. Frame career changes as strategic decisions, not apologies.
How Cover Letters Work with ATS Systems
Here is what most guides will not tell you: your cover letter has two audiences, and they read it differently.
The Robot: ATS Parsing
About 40% of Applicant Tracking Systems parse cover letters alongside resumes. This means the ATS is scanning your cover letter for relevant keywords — job titles, skills, certifications, and industry terms from the job description.
What this means for you:
- Naturally include 3–5 key terms from the job posting. If they are asking for “project management,” “stakeholder communication,” and “Agile methodology,” those phrases should appear in your cover letter.
- Use plain text formatting. No headers, tables, graphics, or fancy fonts. Simple paragraphs are all you need.
- Save as PDF or DOCX (match whatever format the application requests). Never submit a cover letter as a JPG or image-based file.
- Include the exact job title as it appears in the posting. If the role is “Senior Product Designer,” write that — not “Senior UX/UI Designer” or “Design Lead.”
The Human: Hiring Manager Review
If your application passes the ATS screen, your cover letter lands in front of a human. And humans care about entirely different things than robots:
- Personality and voice. A cover letter is your chance to sound like a real person, not a LinkedIn bio generator.
- Specificity. Vague claims are ignored. Specific numbers and stories are remembered.
- Motivation. Hiring managers want to know why you want this job, not just any job.
- Writing quality. For many roles, your cover letter is a direct sample of your communication skills.
