Cover Letters

Do You Still Need Them?

Cover letters are controversial. Some recruiters never read them. Others consider them essential.

The answer: it depends. This chapter covers when you need them and how to write them well.

When Cover Letters Matter

Always Write One When

It's required. If the application asks for one, include one.

You're making a career change. Your resume alone may not explain why you're a fit.

You have gaps or unusual circumstances. A cover letter can briefly address concerns.

You have a referral. Mention who referred you.

You're applying to a small company. More likely to be read.

The job explicitly asks for one. Obviously.

You Can Skip When

It's explicitly optional and you're a clear fit. Your resume speaks for itself.

The application system doesn't have a field for it. Don't force it.

Mass applying to many jobs. Customize resumes, skip personalized letters for volume applications.

The Default

When in doubt, include one. A good cover letter never hurts. A missing one occasionally does.

What Cover Letters Do

They're Not Resume Summaries

Don't repeat your resume in paragraph form. Cover letters should add something:

• Why you want this specific role
• Why you're a fit beyond what's on paper
• How to interpret your experience
• Personality and communication style

They Show Interest

A tailored cover letter signals you didn't just blast applications to 100 companies.

They Address Concerns

Gaps, career changes, and other issues can be briefly explained.

They Demonstrate Communication

How you write shows how you'll communicate as an employee.

Cover Letter Structure

Format

• One page maximum
• 3-4 paragraphs
• Standard business letter format
• Same header/font as your resume (for consistency)

Structure

Opening: Why you're writing and why you're interested.

Middle (1-2 paragraphs): Why you're qualified. Connect your experience to their needs.

Closing: Call to action and enthusiasm.

Writing Each Section

The Opening

Hook them immediately. Options:

Direct approach: "I'm applying for the Marketing Manager position at [Company]. With 8 years of B2B marketing experience and a track record of exceeding pipeline goals, I'm excited about the opportunity to lead your demand generation efforts."

Connection approach: "When Sarah Chen suggested I apply to [Company], I immediately recognized the fit. Your focus on data-driven marketing aligns perfectly with how I've built my career."

Interest approach: "Your recent launch of [Product] caught my attention. As someone who has led three product launches in the same space, I'd love to contribute to your team's continued growth."

What to Avoid in the Opening

• "I am writing to apply for..." (boring)
• Your entire life story
• Generic statements about looking for opportunities
• Excessive flattery about the company

The Middle

This is your argument for why you're qualified.

Connect to their needs: Pick 2-3 requirements from the job description. For each, briefly explain how your experience matches.

Use specific examples: Don't just claim you have skills. Show evidence. "At [Company], I led the team that increased lead conversion by 40%..."

Don't repeat your resume: Reference it ("As you'll see in my resume..."), but add context and personality.

Example Middle Paragraph

"Your listing emphasizes building marketing automation capabilities. At [Previous Company], I implemented HubSpot across a 5-person team, creating automated nurture sequences that improved lead-to-opportunity conversion by 35%. I'm excited to bring this experience to [Company] and help build scalable processes for your growing team."

The Closing

Restate interest: "I'm genuinely excited about the opportunity to contribute to [Company]'s mission."

Call to action: "I'd welcome the chance to discuss how my experience aligns with your needs."

Professional close: "Thank you for your consideration."

Sign-off: "Best regards," or "Sincerely," followed by your name.

What Makes Cover Letters Work

Specificity

Generic letters are obvious. Show you know the company, the role, and how you fit.

Conciseness

Recruiters are busy. Say what you need to say and stop.

Enthusiasm

Show genuine interest. Excitement is more memorable than competence alone.

Connection to Their Needs

Every sentence should relate to what they're looking for, not what you want.

Professionalism

Error-free. Well-formatted. Appropriately formal.

What Makes Cover Letters Fail

Generic Templates

"Dear Hiring Manager, I am excited to apply for [Position] at [Company]..."

When it's obviously copy-pasted, it signals low interest.

Too Long

More than one page. Huge paragraphs. Nobody reads them.

Repeating the Resume

If the cover letter just restates bullet points, what's the point?

Focusing on Yourself

"I want this job because it would help my career" vs. "I can contribute X to your team."

Typos and Errors

One mistake might be forgiven. Multiple mistakes suggest carelessness.

AI Prompt: Cover Letter Writing

Help me write a cover letter.

Job I'm applying for: [Title at Company]

Job description key points:
[Paste key requirements]

My relevant experience:
- [Relevant experience 1]
- [Relevant experience 2]
- [Relevant experience 3]

Why I want this job:
[Your genuine reasons]

Any special circumstances:
[Referral, career change, relocation, etc.]

Write a concise cover letter that:
1. Opens with a strong hook
2. Connects my experience to their needs
3. Shows genuine interest
4. Is no more than 4 paragraphs
5. Has a confident but not arrogant tone

When to Customize vs. Template

Always Customize

• Company name (obviously)
• Why this specific company
• The specific role you're applying for
• Connection to their specific needs

Can Be Templated

• Basic structure
• General statements about your value
• Closing language

Never Send Identical Letters

If you can't customize at all, question whether you should write one.
