How to Write a Thank You Letter to a Professor (Easy Steps + 15 Examples)

Ever had a professor who made a significant impact on your learning journey? One who made complex ideas simple or who motivated you to reach beyond your comfort zone? Writing a thank-you letter to that professor is a heartfelt way of expressing your gratitude. 

But how do you start, and what should you say? No worries! We’re here to guide you through writing a heartfelt thank-you note. Let’s get started!

Understanding The Purpose Of Your Thank-You Letter

A thank-you letter to your professor is not just about good manners. It’s a chance to show gratitude and build a lasting connection.

Here’s what your letter can do:

  • Express gratitude: Your letter shows appreciation for the professor’s time, effort, and commitment. It tells them their hard work doesn’t go unnoticed.
  • Build connection: When you write to your professor, it helps form a more personal bond. This connection can be helpful in your academic journey and beyond.
  • Reflect growth: Your letter can show how the professor’s guidance has impacted you. It lets them know they’ve made a difference in your learning and growth.

Steps In Writing The Thank-You Letter

1. Decide On The Mode Of Delivery

Picking the best way to deliver your thank you letter to your professor is very important. The format you use depends on a few things:

  • Closeness: How close you are to the professor can help you decide. If you are close, a handwritten note might be a good idea. If not, an email might be best.
  • Professor’s preference: Some professors might prefer emails over letters, or vice versa. It might be good to know what they like.
  • Timing: An email might be faster if you want to say thank you immediately. A handwritten letter can take a few days to reach.

After considering such, you can consider using the following:

Traditional Handwritten LetterThis mode can convey a deeper sense of personal connection and effort. Ideal if you have a strong relationship with the professor and there’s no immediate rush.
EmailThis mode is quick and efficient if you want to express your gratitude promptly. It’s also suitable if the professor prefers digital communication.
CardA card is a middle ground between a full handwritten letter and an email. It’s more personal than an email but less formal and time-consuming to write.

2. Address The Professor Correctly

When writing your thank you letter, correctly addressing your professor is essential. If they hold a Ph.D., you should use “Dr.” before their last name. If not, the term “Professor” is appropriate. 

This is not just a matter of etiquette; it also shows respect and appreciation for their achievements.

Tip: Double-check the spelling of your professor's name. It's a small detail, but one that's important. An error in the name can lead to a negative impression, which is the last thing you want in a thank you letter.

3. Begin With A Courteous Greeting

Starting the letter with a courteous greeting sets the tone for the rest of the message. You can use formal greetings such as “Dear Professor [Last Name]” or “Dear Dr. [Last Name].” 

To illustrate, if your professor’s last name is “Smith,” you could start with “Dear Professor Smith” or “Dear Dr. Smith” if they hold a doctorate.

4. Convey Your Appreciation Clearly And Sincerely

It’s essential to state the purpose of your letter right from the start. Express your gratitude clearly and sincerely. Being honest and straightforward about your feelings of gratitude will help your professor understand the depth of your appreciation. 

As William Arthur Ward once said, “Feeling gratitude and not expressing it is like wrapping a present and not giving it.” So, make sure to unwrap your gift of gratitude in your letter.

5. Detail The Impact Of The Professor’s Actions Or Influence

After expressing your appreciation, provide specifics about why you’re grateful. 

  • Did the professor provide exceptional guidance during a challenging project? 
  • Did they offer invaluable advice that helped shape your career decisions? 

Be specific about these details to give your professor a clear understanding of their positive impact on you.

Tip: Use simple, strong words to convey your feelings. For instance, instead of writing, "You are a good professor," you could write, "Your guidance has had a profound impact on my academic success."

6. Share Specific Anecdotes Or Memories

Including specific anecdotes or memories can add a personal touch to your thank you letter. Reflect on your time in your professor’s class and share a memorable moment where they made a difference. It could be a joke they told that eased the class’s tension or perhaps a particularly inspiring lecture. 

These memories reinforce your gratitude and remind the professor of the positive environment they’ve created. It fosters a sense of connection and camaraderie, making your professor feel more appreciated.

7. Communicate The Influence On Your Personal Growth

Your professor will appreciate hearing about their influence on your personal growth. Have they helped boost your confidence? Did their course lead you to discover a passion you didn’t know you had? 

Sharing these personal insights adds another layer of sincerity to your gratitude.

Tip: Consider writing something like this: "Your support helped me believe in myself and pursue my love for biology," or "Your unwavering support has enriched my knowledge and boosted my confidence..."

8. Reiterate Your Gratitude

Before closing the letter, it’s important to reiterate your gratitude. This reaffirms the purpose of your message and emphasizes your sincere appreciation. 

You could use alternative phrases like “I am truly thankful for…” or “I am genuinely grateful for…” to add variety to your expressions of thanks.

9. End On A Positive Note

Ending your thank you letter on a positive note leaves a lasting impression. You could: 

  • Express optimism for the future.
  • Wish your professor well.
  • Convey your excitement about continuing to learn from them.
Tip: Positive endings can help to cement a message in a reader's memory. So, leaving your professor with a positive message can help them remember your gratitude long after they've finished reading.

10. Choose The Right Sign-off

Choosing the right sign-off is crucial for maintaining the tone of your letter. If your letter has been quite formal, sign-offs like “Kind regards” or “Sincerely” might be the most suitable. This last element should align with the tone of the rest of your message.

11. Sign Your Full Name

Sign off with your full name. This removes any ambiguity about who the letter is from, especially in a large class, and it also adds a formal touch to your message.

For example, if your name is Alex Johnson, make sure to sign the letter as “Alex Johnson,” not simply “Alex.”

12. Check For Grammatical And Spelling Errors

Once your letter is written, the work isn’t entirely done. You should thoroughly proofread the message to ensure there are no grammatical or spelling errors. A clean, error-free letter shows you’ve taken the time to create a polished message, which reflects positively on you.

13. Ensure Clarity And Coherence

Beyond just grammatical correctness, your letter should also be clear and coherent. Make sure your sentences flow well and that your thoughts are organized. A well-structured letter will be more impactful and easier to read.

Tip: Consider asking a friend to read your letter. They might catch mistakes you've overlooked and can provide feedback on how your letter might be received.

14. Verify The Tone And Overall Impression

Read your letter one more time, focusing on the tone and overall impression. 

  • Does it come off as genuinely appreciative and respectful?
  • Does it convey the depth of your gratitude effectively?

If your answer is yes, then you have done a good job. 

Additional Tips

  • Be timely: Aim to send your thank-you note soon after the professor’s help or after the event that triggered your gratitude. Promptness shows you value their effort.
  • Keep it simple: Your letter doesn’t have to be lengthy or filled with complex words. A few heartfelt lines can have a strong effect.
  • Stay professional: While it’s a thank-you note, remember to maintain a professional tone. After all, it’s an academic communication.
  • Avoid excessive flattery or insincere praise: Keep your gratitude sincere and honest. Avoid over-praising as it can make your note come across as insincere.

Frequently Asked Questions

What should I do if I didn’t get a chance to hand over the letter in person or missed sending it at the right time? 

Don’t worry if you couldn’t hand over the letter in person or missed the ideal moment to send it. The expression of gratitude is valuable, no matter the timing. 

If the opportunity for an in-person handover has passed, you can send the letter by email or postal mail if you have the professor’s address. 

If it’s been some time since the event or the semester you wanted to refer to, you can simply acknowledge this in your letter, for example: “I’ve been meaning to write to you since the end of last semester to express my gratitude for…” 

Remember, it’s better late than never.

Can I write a thank-you letter to a professor even if I didn’t do well in their class?

Absolutely. A thank-you letter to a professor is about acknowledging the efforts they made towards your learning and academic journey.

Even if you didn’t excel in their class, you could have still learned valuable lessons or gained insights you’re grateful for. 

Your grades do not invalidate the appreciation you have for their guidance. In your letter, you can focus on the knowledge you gained, the growth you experienced, or the inspiration you received.

Can I ask for feedback on my thank-you letter before sending it?

Yes, asking for feedback can be a good idea, especially if you’re unsure about the tone or content of your letter. A trusted friend, family member, or mentor could provide helpful insights. 

Some schools also have writing centers that offer services to review and give feedback on such letters. However, remember to keep the feedback process confidential and respect the privacy of your professor.

Can I use humor in my thank-you letter?

Using humor in a thank-you letter depends largely on your relationship with the professor and their personality. If you have often shared light-hearted moments or if humor was a part of your interactions, it might be fitting to include a touch of it in your letter. 

However, the humor should be appropriate and respectful. Remember, the main aim of the letter is to express gratitude, so ensure that the humor does not overshadow this purpose.

If you’re uncertain, it’s best to maintain a sincere and respectful tone throughout the letter.


Writing a thank-you letter to a professor isn’t as hard as it might seem. It’s all about speaking from the heart and acknowledging the effort your professor has put into your academic journey. 

Remember, a simple thank you can go a long way in showing your appreciation and building lasting connections. So, go ahead and make your professor’s day a little brighter with your thoughtful letter.
