Internship Cover Letter Example
An internship application is judged on potential, not track record. The letter below is from a second-year marketing student applying for a summer internship. Instead of listing modules, she picks one university project, shows what she did in it and links it to the company's own work.
Application for Summer Marketing Internship (June–August)
Dear Ms Okafor,
I am a second-year Marketing student at Northbrook University and I would like to apply for your summer marketing internship. I have followed Brightline Media's work for local food brands since your campaign for Harbour Bakery, and I would like to spend this summer learning how a small agency plans and measures that kind of work.
In my digital marketing module this spring, my team of four ran a three-week Instagram campaign for a student-run café on campus. I was responsible for the content calendar and for tracking results. By testing two posting times and switching from product photos to short videos of the staff, we grew the café's followers from 310 to 1,050 and its weekday lunch sales rose by around 15% during the campaign.
Outside my course, I write the newsletter for the university hiking society, which goes to 600 members every fortnight. It has taught me to write short, plan ahead and hit a deadline every time.
I am available full time from 9 June to 29 August and I am comfortable with Canva, Meta Business Suite and Google Analytics. I would be glad to send examples of the café campaign posts.
Thank you for considering my application. I would welcome the chance to talk about how I could help your team this summer.
Kind regards,
Sofia Marin
Why this internship letter works
- The first paragraph proves interest with one specific campaign, not with "I have always been passionate about marketing".
- One project, told in detail, beats a list of modules. The reader learns her role, the method and the result.
- The numbers are modest but real. Recruiters do not expect big results from students; they expect evidence that you measure what you do.
- The extracurricular paragraph adds a second skill (writing to a deadline) without repeating the first.
- Exact dates and tools answer the practical questions a manager would otherwise have to ask.
What to put in an internship cover letter
Your course and year
Say what you study, where and in which year. It tells the reader at a glance whether you meet the internship's requirements.
One project with a result
Choose the coursework, dissertation, competition or society project closest to the internship. Describe your part in it, not the team's, and give the outcome, even if it is a grade or feedback from a tutor.
Why this organisation
Mention a piece of their work, a product or a value that genuinely interests you. One specific detail is more convincing than a paragraph of praise.
Dates and practical details
State when you are available and, if relevant, whether the internship counts towards your degree or needs an agreement with your university.
Mistakes students make in internship letters
- Describing what the internship will do for you rather than what you can do for them. Mention what you want to learn, but briefly.
- Copying the CV's list of modules into sentences.
- Using the same letter for ten companies with only the name changed.
- Leaving out dates, which is often the first thing an internship coordinator checks.
- Writing more than one page. A focused letter of 250 to 300 words is enough.
Frequently asked questions
How do I write an internship cover letter with no experience?
Use coursework, projects, society roles and part-time jobs as your experience. Pick the one closest to the internship and describe what you did and what came of it. Interns are hired on potential, so evidence that you learn quickly and finish what you start is what counts.
How long should an internship cover letter be?
Around 250 to 300 words, on one page. Internship coordinators often read dozens of letters for one place, so a short letter with one strong example works better than a long one.
Should I mention my grades in an internship letter?
Mention them if they are strong or if the posting asks for a minimum. Otherwise a project with a concrete result usually says more about you than an average.
Who should I address an internship cover letter to?
To the person named in the posting, often the internship coordinator or the team manager. If no name is given, check the company website or LinkedIn, and if you still cannot find one, "Dear Hiring Manager" is fine.
