How to Write a Letter of Appreciation

Your appreciation letter doesn't need to be long or handwritten on fancy paper, but you should consider the following:


Are you sending a personal or professional email or letter?

An email is ideal if you want the recipient to receive your gratitude immediately. A personal letter is better suited for a friend, family member or close contact.

The professional business letter should be used for more formal situations, such as an employer, mentor or contact, addressed and printed on quality paper.


If you are close to the recipient, you can use more casual language. If they are a professional acquaintance, more formal language should be used.


Professional letters should start with "Dear [title name]." Personal letters can use first names or nicknames if you are close to the recipient. Emails to colleagues can also use first names.

Message Body

Begin by stating why you are writing and the reason you are so thankful. For example, "I am writing today to thank you/show gratitude..."

Follow with more specific details about what they did and its impact. Conclude by reiterating your gratitude.


If this letter is to a friend or family member, sign off how you would a birthday card with one of the following, depending on the person:

  • Much love
  • All my love
  • Love
  • From

For formal letters and emails to colleagues, employees or other professional connections, use phrases such as:

  • Respectfully
  • Yours sincerely
  • Best regards

Tips for Your Appreciation Message

Now you know how to write an appreciation letter, here are some tips to help you improve your writing:

  • Send the letter promptly to show sincerity – Sending a letter or email promptly shows the recipient that you genuinely appreciate them and their actions. If you are sending a letter to a colleague, mentor or new contact, it also shows them that you have excellent communication and self-management skills.

  • Be specific – Detail exactly what that person did and why it meant so much to you. Your letter shouldn't be long, but it should be detailed enough to demonstrate their actions and your gratitude.

  • Don't add unrelated information – There are two reasons for this. The first is that it shows your sincerity, as you have made an effort to contact them specifically for this reason. Adding in anything unrelated will take away from the message. The second is that the recipient might use this letter as evidence of performance and character in their portfolio. Any additional information might not be suitable for others to read.

  • Proofread – Before sending your letter, run your document through a spell checker or software like Grammarly. Alternatively, have someone else read it. Not only can they proofread for spelling and grammar, but they can check the content and sincerity.

  • Self-management
  • Motivation
  • Integrity

Final Thoughts

Letting someone know you appreciate their actions is a guaranteed way to improve their day and motivate them to continue their efforts.
