Internship Cover Letter Example

Here's a professional internship cover letter example you can use as a reference. Customize it with your own experience, achievements, and the specific company details.

Dear [Hiring Manager],

I am writing to apply for the Summer Marketing Internship at [Company Name]. As a junior at Boston University majoring in Communications with a concentration in Public Relations, I am eager to gain hands-on experience at a company whose creative campaigns and brand storytelling I have long admired.

My coursework in digital marketing, consumer behavior, and media analytics has given me a strong theoretical foundation that I have already begun putting into practice. As Social Media Director for our university's student-run PR agency, I manage content calendars for three client accounts, create original graphics in Canva, and analyze engagement metrics to refine our strategy. Last semester, I increased one client's Instagram engagement by 45% through a targeted content series. I also write for the campus magazine, which has sharpened my ability to craft compelling narratives for specific audiences.

I am drawn to [Company Name] because your campaigns consistently demonstrate the kind of creative, data-informed marketing I aspire to practice. I am looking for a mentorship-rich environment where I can contribute my creativity and analytical skills while learning from industry professionals. I am a quick learner, highly organized, and comfortable working in fast-paced, collaborative teams.

I would love to discuss how I can contribute to your team this summer. Thank you for considering my application, and I look forward to the opportunity.

Sincerely, [Your Name]
