How to Write a Cover Letter for an Internship (With Examples)

Applying for an internship is a classic chicken-and-egg problem. Employers want experience, but you need the internship to get experience. Your cover letter is where you break that cycle.

A strong internship cover letter leans on what you do have: coursework, projects, extracurriculars, soft skills, and genuine enthusiasm. This guide walks you through exactly what to write, with 5 full examples you can adapt.

Why the Internship Cover Letter Matters More Than You Think

Internship hiring managers know applicants are students. They are not expecting 5 years of experience. What they are looking for is:

1. Evidence that you understand the role (you have read the description carefully)
2. Proof that you have transferable skills (from coursework, projects, or part-time work)
3. Genuine interest in the company (not just any internship)
4. Professionalism and attention to detail (the cover letter itself is a test)

Because you likely have limited work experience, your cover letter has to work harder than it would for a seasoned professional. It is often the deciding factor between candidates with similar CVs.

Internship Cover Letter Structure

Keep it to half a page, around 250-350 words. Use this structure:

Header

Your name, email, phone, LinkedIn (if relevant), and the date. Keep it clean.

Greeting

Name the hiring manager if possible. If not, "Dear Hiring Manager" or "Dear (Department) Team" both work. Avoid "To Whom It May Concern." For more options, see our guide on how to address a cover letter without a name.

Opening paragraph

State what you are applying for and give one specific reason you are interested in this company. Avoid generic openings like "I am writing to apply for your internship."

Body paragraphs

Cover:

• Relevant coursework or modules (with grades if strong)
• Projects or research work
• Part-time jobs, volunteer work, or extracurriculars
• Specific transferable skills tied to the role

Closing paragraph

End with enthusiasm, a clear call to action, and a thank-you.

How to Address Lack of Experience

The biggest mistake candidates make is apologising for their lack of experience. Do not do this. Instead, reframe what you have.

Instead of listing what you lack, list what you have:

• Coursework: Specific modules or projects that cover the same topics
• Self-directed learning: Online courses, certifications, independent reading
• Academic projects: Dissertation topics, group projects, competitions
• Part-time jobs: Even unrelated roles teach reliability, time management, and customer skills
• Volunteer work: Shows initiative and commitment
• Extracurriculars: Society leadership, sports captaincy, debate club, student newspapers
• Personal projects: Side businesses, blogs, coding projects, creative portfolios

5 Full Internship Cover Letter Examples

Example 1: Marketing Internship

Dear Ms Gonzalez,

I am writing to apply for the Summer Marketing Internship at Blythe & Co. Your recent podcast episode on brand repositioning for legacy retailers was what prompted me to apply. Your approach to balancing heritage with modernisation is exactly the kind of work I want to start learning from.

I am a second-year Marketing student at the University of Leeds, on track for a first-class degree. Last summer I completed a 6-week placement at a digital agency where I managed social content for three SME clients, growing combined Instagram followings by 60%. My final module project analysed a rebrand case study and scored the highest grade in my cohort. I am proficient in Google Analytics, Meta Ads Manager, Canva, and basic HTML.

Beyond coursework, I have run a sustainable fashion newsletter for 18 months that now reaches 5,000 monthly readers. That project has taught me about audience building, content planning, and editorial discipline. I would love to bring that self-directed learning approach to your content team this summer.

Thank you for considering my application. I have attached my CV and portfolio, and I would welcome the opportunity to discuss how I can contribute.

Yours sincerely,

Aisha Khan

Example 2: Software Engineering Internship

Dear Hiring Manager,

I am applying for the Software Engineering Intern role at Payworks. Your engineering blog post on migrating from monolith to microservices mirrors what I studied in my systems architecture module this year, and the chance to work on a real production migration is the reason I am specifically interested in your team.

I am a second-year Computer Science student at Manchester, with grades averaging 78% across core modules. My current modules cover distributed systems, databases, and software engineering practice. For my last team project, I built a full-stack task management application using React, Node.js, and PostgreSQL, which scored the top grade in a cohort of 60. I also contribute to open-source: last term I merged a small bug fix into a Python library I use for personal projects.

Outside the classroom, I have completed AWS Cloud Practitioner certification and I am working through the Educative.io microservices course. I am comfortable in Python, Java, and JavaScript, and I have basic Docker and Git experience.

Thank you for considering my application. I have attached my CV and GitHub link, and I am available for interviews any weekday after 4pm.

Yours sincerely,

Liam Carter

Example 3: Finance Internship

Dear Mr Davies,

I am writing to apply for the Summer Analyst internship at Northfield Capital. Your team's focus on small-cap UK equities is the area I have been studying in depth during my second year, and the interview with your head of research on the Invest Like the Best podcast made clear the kind of rigorous, bottom-up approach I want to learn.

I am a second-year Economics student at UCL, currently on track for a first. My recent modules in Financial Markets and Corporate Finance included detailed company valuation work using DCF and comparable analysis. For my last research project, I built a 3-statement model on Games Workshop and presented the thesis to my tutor, who encouraged me to submit it to the student investment club. I have also been an active member of UCL Investment Society, where I pitched 2 stocks to the small-cap subcommittee in the past year.

My technical skills include Excel (including advanced functions and basic VBA), Python (pandas, yfinance), and basic Bloomberg Terminal familiarity from a workshop I completed last spring.

Thank you for the opportunity to apply. I have attached my CV and transcript, and I would welcome a conversation about how I can contribute this summer.

Yours sincerely,

Sophie Laurent

Example 4: Healthcare / Research Internship

Dear Dr Wilson,

I am writing to apply for the 8-week research internship with your clinical trials group. Your lab's recent paper on patient-reported outcomes in cardiac rehabilitation shaped my undergraduate dissertation proposal, and the chance to work in an active clinical research setting is exactly what I need at this stage of my degree.

I am a final-year BSc Biomedical Sciences student at King's College London, with a strong grounding in clinical research methods and statistics. My current modules include Clinical Trials and Evidence-Based Medicine, where I scored in the top 10% of my cohort. For my dissertation, I am conducting a systematic review of physical activity interventions in post-stroke patients, which has involved screening over 200 papers and extracting data into a structured database.

Beyond coursework, I have volunteered with Age UK for 2 years, which gave me regular direct contact with older adults and taught me how to communicate clearly about health topics. I also completed a short RStudio course to handle statistical analysis for my dissertation.

I would welcome the chance to contribute to your team's data collection and analysis work this summer. Thank you for considering my application.

Yours sincerely,

Emma Richards

Example 5: Graphic Design Internship

Dear Ms Chen,

I am applying for the Summer Graphic Design Internship at Field & Form. Your identity work for the Barbican's 2025 season is some of the most considered brand design I have seen this year, and the thinking behind combining archival references with a contemporary grid is exactly the kind of work I want to learn from.

I am a third-year BA Graphic Design student at Central Saint Martins. My current portfolio includes a full brand identity project for a fictional independent publisher, packaging design for a coffee roaster, and editorial design for a self-published magazine. My tutors have particularly praised my typographic work, which has been shortlisted twice for the departmental exhibition.

My toolkit covers Adobe Creative Suite (Photoshop, Illustrator, InDesign, After Effects), Figma, and basic motion graphics. I also run a personal Instagram account focused on book cover design that has grown to 2,400 followers over the past year.

Thank you for considering my application. I have attached my CV and a PDF portfolio, with my full portfolio available at (URL).

Yours sincerely,

Jamie Harris

Email vs Attached Cover Letter

When to paste the letter into the email body

If the application is informal (startups, smaller agencies, or direct outreach), pasting the letter into the email works well. Keep the subject line specific.

When to attach the letter as a PDF

If the application is through a formal portal or a corporate email address, attach it as a PDF. PDFs preserve formatting across devices, unlike Word documents.

Hybrid approach

Paste a short 3-sentence version into the email body, then attach the full letter as a PDF. This is a good middle ground for most applications.

For more on professional email practice, see our email when sending CV guide.

Common Internship Cover Letter Mistakes

1. Apologising for your lack of experience

Do not mention what you lack. Focus on what you have.

2. Generic openings

"I am writing to apply for your internship" tells the reader nothing. Lead with something specific about the company.

3. Just repeating your CV

The letter should add context and voice. If it is just a prose version of your CV, you are missing an opportunity.

4. Forgetting to research the company

Reference something specific: a recent blog post, a product, a piece of work, a news item. This proves you have actually looked at the company.

5. Being too long

Half a page is the sweet spot. Recruiters for internships are typically reviewing hundreds of applications. A long letter gets skimmed.

6. Typos and formatting issues

Proofread. Then proofread again. Then ask a friend to proofread. Small errors in a short letter are especially damaging.

Industry-Specific Tips

For tech internships

Link to your GitHub, show a project portfolio, and mention specific frameworks or languages from the job description. Specificity matters.

For finance internships

Demonstrate technical skills (Excel, Python, modelling) and show investment interest through society memberships, stock pitches, or independent research.

For creative internships

Always include a portfolio link. Reference specific work from the studio or agency you are applying to. Show that you understand their visual approach.

For non-profit internships

Lead with mission alignment. Reference specific programmes you admire. Show that you know what the organisation does.
