As an intern there are two big things going through your head at any point in time. The first is that you want to do a good job over the course of your however-month-long internship. The second is that you want to do a good enough job to grow your professional network and job prospects.
I speak from experience—as a college senior, I was able to turn an editorial internship into a full-time role I loved by the time I graduated (of course, it came after getting rejected and following up with the hiring manager, but that’s a story for another day).
If there’s one lesson I’ve learned from that time in my life, as well as all the times I’ve managed interns over the course of my career, it’s that the little things go a long way in helping you stand out. It includes sending a post-internship thank you letter to your supervisor (and some other people, too). Here we teach you how to write one.
Why send a thank you letter after an internship?
I guess you could ask the same question about any thank you note. Why would you send one after an interview? Or after an informational interview? Even after getting promoted? Well, it’s polite. It shows respect for the person’s time, tutelage, and resources. It also acknowledges that you’re one of the lucky few who got the opportunity—and don’t take that lightly.
It’s also memorable. Just as job candidates or networking dates come and go in the blink of an eye, so do interns. When you put yourself in front of your supervisor and peers one last time in a professional, compelling manner, you force them to remember you—often for months or years to come, and hopefully when important career opportunities pop up.
Worst-case scenario, if every other intern sends a thank you note, at least you won’t look silly having missed the boat. Best-case scenario, if they don’t send one, you’ll stand out in an excellent way.

How to write a post-internship thank you letter in 6 steps
Staring helplessly at your computer trying to decide what to write? Here’s a step-by-step guide on how you can go about your message:
1. Pick your medium
Decide how you want to send your note. If you think it’s appropriate or want to make it super personalized, go for a handwritten card. You can hand it to them in person, leave it on their desk, or mail it afterward.
If that’s not possible or you feel uncomfortable doing so, shoot them a nice email—that’s perfectly acceptable, too. Especially if you work remotely and still want them to get your thanks quickly and easily. It’s all about feeling out the situation and what your boss or supervisor might appreciate.
2. Actually say “thank you”
I hate having to say this, but yes, your note should say “thank you” somewhere in it—ideally in the first sentence of your letter and in the subject line of your email. For example, you can start with “Thank you so much for the opportunity to work on the [team] this summer.”
Or, “It’s been a pleasure working with you these past [x weeks/months]. I wanted to thank you for all you’ve done for me…”
3. Specifically say what you're thankful for
Next, dive into some specific details of your experience that you’re thankful for. What was your favorite moment working with the team? What projects were you proud to be a part of? What was some advice or guidance your supervisor or colleague gave you that really resonated with you or helped you grow?
Here’s what that could look like:
“I’m so grateful for all the feedback you provided on my articles and patience you had as I learned more about content creation. I know I’ve become a stronger writer and editor thanks to you.”
One more example:
“It’s been so enjoyable to watch the recruiting process in action and help streamline how you onboard new hires. I look forward to taking what I’ve learned with me into my job search and applying these strategies to future HR roles I take on.”
4. Let them know you’d like to keep in touch
Make it clear you’d love to stay connected by providing your personal contact information either in the body of your note or in your signature (hopefully they’ll do the same!). An email address works great. If it seems relevant, you can also add your phone number or social media.
Use this opportunity to also express an interest in a full-time position down the road, if that’s something you’re looking for. You definitely don’t want to explicitly ask for a job, but you’ll want to reiterate how much you’ve enjoyed your experience and that you’d be excited to come on board as a permanent employee.
It could look like this:
“I’d love to stay in touch as I finish up my senior year. This team has been absolutely wonderful to work with, and if your company is looking to hire some more talent next year I’d be thrilled to apply. You can reach me at [email address].”
Pro tip: Copy your personal email address on your thank you note if you’re sending it from a professional address. This makes it retrievable even after you’ve left (should you want to revisit your conversation), and immediately gives the receiver your contact information.
5. Make it fun (if possible)
If you and your colleagues got along swimmingly over the course of your internship, it’s always nice to add some flair and humor to your note—just for that extra bit of personalization. Think about fun interactions or experiences you had together and mention it towards the end of your letter.
For example, you might say: “I’ll miss all our weekly team lunches—especially Taco Tuesdays. I hope the next time I’m in town we can bring them back one more time!”
You could also say something along the lines of: “In addition to being an incredible supervisor, thank you for all the amazing GIFs you sent my way. They truly made my inbox better, and I now feel ready to take on the working world with the skills to pick the perfect GIF for any meeting.”
6. Spell and grammar check, sign, and send
You don't want your last impression to be stained by typos or grammatical errors. Like you'd do with a cover letter or resume, spell and grammar check your note or email. After assuring everything is correct, sign and send. You can use any closing you want (e.g. “Warmly,” ”Best regards,” “All the best”) as long as it has a professional tone.
What not to do in a thank you note or email
There are certain things you should never say in an internship thank you letter (or any professional letter). Here are some don'ts to keep in mind:
- Don't exaggerate your compliments. As much as you want to express your gratitude and how much you loved your experience, being too over the top with your compliments will sound phony and disingenuous. So, tone it down.
- Don't ramble. Thank you notes or emails don't need to be super long, mentioning every good memory you have from your internship. Try to stick to three or four paragraphs max.
- Don't mention negative experiences. It may sound obvious, but you shouldn't use a thank you note to express frustrations about negative experiences. Even if it's something you think you'd be funny or quirk to mention—don't do it.

Bottom line
There you have it, the perfect foundation for leaving an internship with your reputation and job prospects in great shape. The next step? Follow up and actually keep in touch. If you see something that makes you think of your old colleagues, shoot them a note. If you notice they got promoted or changed jobs, send them a “congrats!” on social media.
When you eventually see the role of your dreams available at the company, leverage your supervisor and peers to get a referral. This thank you note in their archives is sure to be a reminder of how great you are—and can help you get a stellar recommendation.
