How to Write a Cover Letter for an Internship (2025 Edition)

Learn how to write a cover letter that gets you hired for your dream internship. Step-by-step guide, real examples, and a free downloadable template.

🚀 Why Most Internship Cover Letters Fail

Let’s be real - most students write cover letters that sound like copy-paste homework.

They start with “Dear Hiring Manager,” repeat the resume, and end with “Thank you for your time.”

That’s why recruiters skip them.

A great cover letter doesn’t summarize your life, it connects your story to their opportunity.
Let’s write one that does.

 💡 What a Recruiter Actually Wants to See
When reading internship applications, recruiters are not looking for perfection, they’re looking for:

• Curiosity
  
• Initiative
  
• A sense of fit
  
• Your cover letter’s job is to prove that you:
• Understand what the company does,
  
• Have skills that can add value,
  
• Care enough to show genuine interest.
  That’s it.

 
🧱 The Perfect Cover Letter Structure (2025)

1️⃣ Header (keep it simple)
 Ava Thompson  
Chicago, IL | [email protected] | (312) 555-4023 | linkedin.com/in/avathompson

Add the date and company info:

April 10, 2025  
Hiring Manager  
BrightPath Marketing Agency  
Chicago, IL

 
2️⃣ Opening Line - Skip the Obvious
Most people start with “I’m writing to apply for...” ❌
Instead, start with energy.

Example:

“When I saw BrightPath’s internship posting, I didn’t scroll past - I opened it immediately. Your campaigns have been part of my digital marketing coursework, and I’d love to contribute to your next big launch.”
You’ve already stood out.

 3️⃣ The “Why You” Paragraph
Explain what makes you a great fit - not with titles, but with proof.

Example:

“As a senior in Communication Studies at the University of Illinois, I’ve led two class projects focused on brand storytelling. One project boosted engagement for a local nonprofit by 40% through social content optimization. That experience showed me the power of data-driven creativity, something I see reflected in BrightPath’s campaigns.”
 
4️⃣ The “Why Them” Paragraph
Show you’ve done your homework. Recruiters can tell when you haven’t.

Example:

“What excites me about BrightPath is your focus on authentic connection between brands and communities. I admire how you integrate social causes into marketing strategies, something I’m passionate about, too.”
 
5️⃣ Closing That Feels Human
Avoid robotic endings. Make it confident, yet kind.

Example:

“I’d be thrilled to bring fresh ideas and a learner’s mindset to your team. Thank you for considering my application. I’d love the opportunity to interview and contribute to your upcoming projects.”

Best regards,

🧩 Real Example: Cover Letter That Got an Internship
"Dear Ms. Patel,

As a Business major fascinated by operations management, I was drawn to GlobalTech’s internship because of your focus on lean process improvement. Last semester, I led a case study on supply chain optimization that reduced costs by 12% in simulation.

I admire GlobalTech’s mentorship culture and would be excited to learn from your team this summer.

Best,
Ryan Chen”
