Writing an Application Letter for Internship That Works

Over the years, I’ve written numerous application letters for internships and have learned what works and what doesn’t. In this guide, I’ll share my insights, provide you with three unique templates, and offer tips based on personal experience to help you craft a compelling application letter.

Key Takeaways

  • Importance of Personalization: Tailor each letter to the specific internship.
  • Structure Matters: Follow a clear, professional structure.
  • Showcase Your Strengths: Highlight relevant skills and experiences.
  • Be Concise and Focused: Keep it to one page, focusing on key points.
  • Professional Tone: Maintain a professional tone throughout.
  • Proofread: Ensure your letter is free from errors.

Step-by-Step Guide to Writing an Application Letter for Internship

1. Understand the Structure





The structure of your application letter is crucial. Here’s a basic outline:

  1. Header: Your contact information and the date.
  2. Employer’s Contact Information: Name, title, company, and address.
  3. Salutation: Address the letter to a specific person.
  4. Introduction: State the position you’re applying for and how you found out about it.
  5. Body: Highlight your skills and experiences relevant to the internship.
  6. Conclusion: Summarize your suitability and express enthusiasm for the role.
  7. Closing: A polite closing statement and your signature.

2. Personalize Each Letter

One of the biggest mistakes applicants make is sending generic letters. Personalize each letter by mentioning the company’s name and specific details about the internship. Research the company and refer to specific projects or values that resonate with you.

3. Showcase Your Strengths

Use the body of your letter to highlight your relevant skills and experiences. Provide concrete examples that demonstrate your abilities. For instance, if you’re applying for a marketing internship, mention any marketing projects you’ve worked on.

4. Maintain a Professional Tone

While it’s important to show enthusiasm, ensure that your letter remains professional. Avoid using slang or overly casual language.

5. Proofread

Before sending your letter, proofread it to eliminate any grammatical or spelling errors. A well-written, error-free letter reflects your attention to detail and professionalism.

Real-Life Example

When I applied for my first internship, I tailored my letter to the company’s ongoing projects. I mentioned how I admired their innovative approach to marketing and referenced a recent campaign they had launched. This personalization caught the hiring manager’s attention, and I secured the internship.
