An internship cover letter for a marketing student

Example written by CV Ajuste · Published 30 October 2026

The letter

Why this letter works

• The opening paragraph leads with relevant experience: the candidate has been «creating Instagram posts and stories in Canva» for a student society.
• The second paragraph connects a society task to the role by explaining that the candidate helps plan a «monthly content calendar» and records engagement in Excel.
• The second paragraph also gives the café role a clear purpose, describing how the candidate works «during busy shifts alongside my university studies».
• The final paragraph makes a direct request: «I would welcome an interview to discuss my application.»

What an internship cover letter should show

For a summer marketing internship, recruiters will want to see how your current studies relate to the work and whether you can explain your experience clearly. In the fictional offer, the employer asks for a student on a marketing, communications or related degree. The example gives the candidate’s course, university and expected completion year, so the reader can understand her position in her studies.

The offer also asks for an interest in digital marketing and confidence creating simple visual content. The letter addresses this through Instagram posts and stories made in Canva for a student society. That example is useful because it names the channel and explains what the content promoted. You do not need a previous marketing internship to describe relevant work, provided the experience you use is your own.

Attention to detail and basic Excel skills matter in the fictional role too. The candidate says she records post engagement in Excel rather than claiming an unspecified level of expertise. If you have used a spreadsheet for a different purpose, explain that task accurately. You might have organised information for a society or tracked activity for a project.

How to adapt this internship cover letter

Start with an activity that relates to the opportunity, then identify the role and employer. In the example, the candidate opens with her society’s Instagram content. If your strongest evidence comes from a university project, explain what you produced and who it was for. If it comes from volunteering, describe your contribution rather than presenting the whole team’s work as yours.

Choose details that respond to the particular offer. A role focused on email campaigns may call for a different example from one centred on social media. Where possible, name the tool you used and the task you completed with it. Only include outcomes you can support. A reliable observation about what you did is more useful than an invented increase in engagement.

The fictional offer lists Google Analytics as a plus, rather than a requirement. The example does not claim that the candidate has used it. If you have relevant experience, explain how you used it. If you have not, leave it out or describe a genuine step you have taken to learn about it. CV Ajuste can help tailor a letter to an offer using your own facts.

Making student and part-time experience relevant

University societies can give you useful material for an internship application. The example describes working with committee members on a monthly content calendar. That tells the employer something about collaboration and planning without assuming that the candidate managed the entire campaign. Your own example could come from helping organise an event or producing content for a group, as long as you state your actual contribution.

Part-time work can also show how you operate with other people. In the example, the café role involves serving customers and working alongside colleagues during busy shifts. Those details help a recruiter understand the candidate’s experience in a workplace. If you include a customer-facing role, select the duties that help explain how you communicate or manage your work.

The fictional offer asks for someone able to manage tasks to deadlines. If you have a genuine example, explain what needed to be completed and how you organised your work. You could draw on a society commitment or an assessed project. Give a brief account rather than promising that you always meet every deadline. If the application asks about summer availability, answer accurately and check the advertised dates before making a commitment.

Mistakes to avoid before sending

Do not copy the example’s details into your own letter. The candidate’s degree dates and society activities belong to the fictional profile. Replace them with information you can explain at interview, and check that the dates agree with your CV. If a project is ongoing, make that clear rather than implying it has finished.

Avoid listing software without saying what you did with it. The fictional candidate’s reference to Excel is useful because it is tied to recording post engagement. If your experience is limited to basic spreadsheet tasks, describe those tasks rather than claiming advanced skills. The same applies to design tools: creating a post from a template is valid experience when presented accurately.

Check the employer’s name and the internship title against the offer. Address the letter to a named person if the application gives one; otherwise, a suitable general greeting is acceptable. In UK correspondence, the example’s “Dear Hiring Manager” pairs with “Yours faithfully”. Read the letter aloud for clarity, then check spelling and formatting. Keep the closing brief and include your name.
