Sample Letter for Internship Training: First Year Student No Experience

Subject: First Year Marketing Intern Application – Lila Reed

Hi Ms. Henderson,

I’m a first year communications student at Westwood College. I saw your team’s recent park cleanup campaign and loved how you used student TikTok creators.

I don’t have formal work experience yet, but I run my dorm’s event page and grew it to 180 followers in 7 weeks. I’d bring that same energy to your team 12 hours a week this semester.

My transcript and page link are attached. Would you have 10 minutes next Wednesday to chat?
Thanks,
Lila Reed

Frequently Asked Questions about Sample Letter for Internship Training

How long should my internship training letter be?

Keep your letter 3 short paragraphs or under 250 words total. Hiring managers do not read full page letters for internship roles.

Do I need to attach my resume with this letter?

Yes, always attach a one page resume alongside your letter. The letter exists only to make someone open that resume.

Can I use the same sample letter for every company?

Never send an identical letter to multiple companies. Change at minimum the hiring manager name, one specific company detail, and the skill you mention.

Should I use formal language for this letter?

Use polite but casual conversational language. Avoid old fashioned phrases like "herewith" or "duly noted". Write like you would speak to a friendly teacher.

What is the best time to send an internship letter?

Send your letter between 9am and 11am on a Tuesday, Wednesday or Thursday. Avoid sending applications late at night or over weekends.

Do I need to mention my grades in the letter?

Only mention grades if they are above a 3.7 GPA or specifically requested. Focus on practical skills or small projects instead.

How long should I wait before following up?

Wait 7 full working days before sending a follow up message. Do not follow up more than two times for one application.

Can I send these letters as text messages?

Always send official internship communications via email. Only use text messages if the hiring manager has already shared their number with you.

Should I add emojis to my internship letter?

Avoid emojis in formal internship applications. Stick to plain text, proper punctuation and standard line breaks.

Every internship application is a small, important conversation. The sample letters shared here are not just templates — they are proven frameworks for starting that conversation well. You can adjust every line to match your voice and the role you want.
