What Is a Summer Internship Letter of Introduction?
A summer internship letter of introduction is a brief, formal letter written by a student or recent graduate to express interest in a summer internship position, highlighting their academic achievements and relevant coursework, as well as relevant experiences.

This letter acts as a personalized pitch and often helps set your application apart from others.

How to Tailor Your Letter to Any Internship Role
A generic letter won’t stand out, but a well-written cover letter can open doors. Here’s how to make your letter more effective in the industry:
1. Research the Company
Mention something specific about the company—a recent campaign, product, or initiative that genuinely interests you.
2. Use Keywords from the Job Post
Pick out key phrases like “team collaboration” or “data analysis” from the internship description and naturally work them into your letter.
3. Match the Company’s Tone
Adjust your language to fit the company culture. A casual startup may prefer an energetic tone, while a corporate firm expects formality.
4. Show the Fit
Every paragraph should say, "I understand what you do, and here’s how I fit in." Connect your skills and goals to their work clearly and confidently.
Tips to Make Your Letter Stand Out
- Be concise: Keep your letter to one page.
- Show enthusiasm: Passion for the role and the company can set you apart.
- Quantify achievements: Include metrics when possible, e.g., "grew club membership by 30%."
- Mention referrals: If someone within the organization has recommended you, please state so.
- Proofread carefully: Spelling or grammar errors can undermine your professionalism.
