What to Include in a Cover Letter (And What to Leave Out)

A cover letter can be the difference between landing an interview and getting lost in the pile. But most job seekers either stuff theirs with the wrong information or leave out the details that actually matter.

The truth is, a cover letter doesn't need to be long or complicated. It needs to be focused. Hiring managers spend about 30 seconds scanning one, so every sentence has to earn its spot. This guide breaks down exactly what belongs in your cover letter, what to skip, and how to structure the whole thing so it works in your favor.

‍

The 6 Essential Parts of a Cover Letter

Every effective cover letter follows the same basic structure. Here's what each section should include and why it matters.

1. A Professional Header

Your header establishes who you are and how to reach you. Keep it clean and consistent with your resume's formatting.

Include:

• Full name
• Phone number
• Email address
• LinkedIn profile URL (optional but recommended)
• City and state (full street address isn't necessary anymore)

Below your info, add:

• The date
• The hiring manager's name (if you can find it)
• Company name
• Company address

Matching your cover letter header to your resume header creates a polished, unified application package. It's a small detail that signals professionalism.

2. A Personalized Greeting

Address your cover letter to a specific person whenever possible. "Dear [First Name] [Last Name]" is the standard format. You can find hiring manager names on LinkedIn, the company's team page, or in the job posting itself.

If you've searched and truly can't find a name, "Dear Hiring Manager" works. Avoid outdated greetings like "To Whom It May Concern" or "Dear Sir/Madam" — they feel impersonal and dated.

3. A Strong Opening Paragraph

Your first paragraph has one job: make the reader want to keep reading. State the specific role you're applying for, then immediately give them a reason to care.

What works:

• Lead with a relevant achievement that connects to the role
• Mention something specific about the company that attracted you
• Reference a connection or referral if you have one

What doesn't work:

• "I am writing to apply for the position of..." (generic and forgettable)
• "I believe I am the perfect candidate..." (let your qualifications speak instead)
• Starting with your life story or career timeline

A strong opener might look like this: "When I saw that Acme Corp was looking for a content strategist to scale its B2B blog, I knew my experience growing organic traffic by 180% at a SaaS startup would be directly relevant."

That's specific, relevant, and gives the reader a concrete reason to keep going.

4. Body Paragraphs That Prove Your Fit

The body of your cover letter is where you connect your experience to the job requirements. This isn't a summary of your resume — it's a highlight reel of your most compelling qualifications, told with context.

Use 1-2 body paragraphs to cover:

• Two to three specific achievements that relate to the job description. Pick accomplishments that show you've already done (or come close to doing) what they're hiring for.
• Quantified results wherever possible. Numbers catch attention and add credibility. "Increased customer retention by 15%" beats "improved customer retention."
• Skills in action. Don't just list skills — show them through brief stories. Instead of saying "strong communication skills," describe how you presented a proposal to senior leadership that secured $200K in budget.
• Knowledge of the company. Reference a specific product, initiative, or company value that resonates with you. This shows you've done your homework, not just mass-applied.

If the job description mentions five key requirements, your body paragraphs should address at least two or three of them with evidence from your background.

5. A Confident Closing Paragraph

Your closing paragraph should do three things: restate your interest, summarize your value, and include a call to action.

A solid closing sounds like: "I'd welcome the opportunity to discuss how my experience in customer success and data analysis could contribute to your team's growth goals. I'm available for a conversation at your convenience and look forward to hearing from you."

Don't beg. Don't be passive. And don't introduce new information here — keep it tight and forward-looking.

6. A Professional Sign-Off

End with a standard closing and your full name:

• "Sincerely,"
• "Best regards,"
• "Thank you,"

Any of these work. Skip overly casual sign-offs like "Cheers" or "Talk soon" unless you're applying somewhere with a very informal culture and you're confident about the tone.

What to Leave Out of Your Cover Letter

Knowing what not to include is just as important as knowing what to put in. These are the most common things that waste space or actively hurt your chances.

Salary Expectations (Unless Asked)

Never bring up money in your cover letter unless the job posting specifically asks for salary requirements. It shifts the conversation from value to cost before you've even had an interview.

Your Entire Work History

Your resume covers your employment timeline. Your cover letter should focus on 2-3 highlights, not walk through every job you've ever had. Repeating your resume in paragraph form is one of the most common cover letter mistakes.

Irrelevant Personal Details

Hobbies, age, marital status, and personal interests don't belong here unless they directly relate to the role. "I enjoy hiking and cooking" tells a hiring manager nothing useful about your candidacy.

Reasons You Left Previous Jobs

Don't explain why you left your last position or address gaps in your resume in the cover letter. If it comes up, that's a conversation for the interview. Your cover letter should be entirely forward-looking.

Apologies or Disclaimers

"Although I don't have direct experience in..." or "I know I may not be the most qualified candidate, but..." undermines everything else you write. If you're applying, own it. Focus on what you bring, not what you lack.

Overused Buzzwords

Phrases like "team player," "go-getter," "hard worker," and "passionate self-starter" have been drained of all meaning. Replace them with specific examples that demonstrate those qualities through action.

Cover Letter Length: How Long Is Too Long?

The sweet spot for a cover letter in 2026 is 250-400 words. That's roughly three-quarters of a page. Anything shorter might feel like you didn't put in effort. Anything longer and you risk losing the reader.

Keep paragraphs to 2-4 sentences each. Use white space. A cover letter that looks dense and heavy will get skimmed or skipped entirely.

How to Tailor Your Cover Letter for Every Application

A generic cover letter is one of the fastest ways to get rejected. Hiring managers can spot a template from a mile away. Each application should include at least three tailored elements:

1. The company name and role — mentioned naturally throughout, not just in the greeting
2. A specific reference to the company's work, product, culture, or recent news
3. Skills and achievements that directly match the job description's top requirements

This doesn't mean rewriting from scratch every time. Build a strong base template, then swap in the tailored details for each role. If time is tight, Seekario's AI Cover Letter Generator can create customized cover letters based on a specific job description in seconds — without the cookie-cutter feel.

Quick Checklist Before You Hit Send

Run through these checks before submitting:

• Does the cover letter address a specific person or at minimum say "Dear Hiring Manager"?
• Does the opening grab attention with a relevant hook?
• Do the body paragraphs include 2-3 achievements with measurable results?
• Is the company mentioned by name with a specific reference?
• Is it under 400 words and on one page?
• Have you proofread for typos, grammar, and formatting?
• Is the file saved as a PDF with a professional filename like "Jane-Smith-Cover-Letter.pdf"?

If you answered yes to all seven, your cover letter is ready to send.

FAQ

Do I really need a cover letter in 2026?

Yes, for most applications. While some job postings say "optional," submitting a strong cover letter gives you an edge over candidates who skip it. It's your chance to show personality, explain motivation, and connect the dots between your resume and the role.

How do I write a cover letter with no experience?

Focus on transferable skills from education, volunteer work, internships, or personal projects. Use the body paragraphs to show enthusiasm for the field and willingness to learn, backed by specific examples of relevant abilities you've demonstrated.

Should a cover letter be the same as my resume?

No. Your cover letter should complement your resume, not duplicate it. Use it to expand on 2-3 key achievements, explain context that your resume can't capture, and show the hiring manager your communication style and personality.

What format should I use for a cover letter?

Use a professional business letter format: header with contact info, personalized greeting, 3-4 concise paragraphs, and a formal sign-off. Save it as a PDF to preserve formatting. Use a standard font (Arial, Calibri, or Garamond) at 10-12 points.
