How to Write an Appreciation Letter | 20 Perfect Samples

There are several ways for individuals or organizations to show gratitude. One of the sincerest and most genuine ways is by writing an appreciation letter. An appreciation letter can help people and organizations appropriately articulate their gratitude.

An Appreciation Letter is a document written by one party to another to show gratitude for a deed done or contribution made. It can also be referred to as a thank you or recognition letter.

An appreciation letter can be a formal, semi-formal, or casual letter depending on the relationship shared between you and the recipient.

An appreciation letter can serve different purposes for an individual and an organization. For example, organizations may use an appreciation letter to show gratitude for the good work employees have done, express their appreciation to employees who have performed their duties above and beyond expectations, and acknowledge employees who have accomplished goals set out by the organization, such as meeting a quota of the work.

This can inspire employees to improve the quality of their work and prompt them to work longer in an organization. On the other hand, individuals may use an appreciation letter to show gratitude for the help they have received from others, strengthening their relations with their network of colleagues, friends, coworkers, etc.

When is a Personal Appreciation Letter Written?

There are maybe occasions when you may feel it necessary to write a personal appreciation letter. The decision on which occasions are appropriate heavily relies on the deed performed or contribution made.

The following are occasions that may warrant the writing of an appreciation letter:

  • When a former employer writes a reference letter recommending  an employee to a job
  •  When a client refers an individual for a job /introduces an individual to another potential customer
  • When a potential employer invites a job seeker for an interview because they are  considering them
  • When employees make significant contributions to their organization
  • When a boss mentors and advises an employee
  • When a coworker steps in to cover a colleague’s shift /carry out their duties for a time
  • When an employee performs  exceptionally  at work to the benefit of the organization
  • When a boss /team leader has demonstrated exceptional leadership
  • When an individual has helped one achieve a goal/reach a milestone

Whenever you feel compelled to recognize the deeds done by another party, you should consider writing an appreciation letter.

Leave an Impact

When trying to forge and grow relationships, one of the most important aspects you should consider is showing gratitude through means like an appreciation letter. The gratitude expressed by your appreciation letter can improve the employee’s work quality and help make them feel valued. It can also energize and motivate employees to work harder.

Gratitude also plays an essential role in the relationships you have or hope to forge with various people, such as friends, coworkers, potential employers, etc. A well-written appreciation letter can help you make a good impression, especially if you are trying to gain the recipient’s favor, such as when seeking a job. An appreciation letter also plays a vital role in ensuring the longevity of existing relationships, primarily when written sincerely.

How to Write an Appreciation Letter?

Learning how to write an appreciation letter can ensure that your gratitude is well conveyed. With the right tools, you can articulate your acknowledgment for deeds performed by others.

When writing an appreciation letter, you should consider the following:

Format  of the letter

The format used to write the appreciation letter will be determined by the reason you are grateful to the recipient, for example, if you are writing the letter because the recipient performed a casual deed such as when a coworker helps you draft an essential document for work, and appreciation email would fit the situation. The email will help ensure that your letter reaches the recipient faster and effectively communicates your gratitude for the favor. The subject line of the email should include the words’ thank you’ to ensure your coworker knows what the email is about.

On the other hand, if you are expressing gratitude for a major deed done by the recipient, such as when your employer promotes you to a higher position, then taking the time to write and send a handwritten letter will show the recipient that the deed done is important to you and was greatly appreciated.

The letter’s length will depend on the amount of praise you would like to bestow on the recipient. For example, a long letter may cover the length of a page, while a shorter letter maybe a paragraph long in an email.

Your appreciation letter should address the recipient directly. For instance, if you draft a formal appreciation letter to your hiring manager, boss, or professor, you may use ‘Dear[Name]’ or ‘Dear Mr/Ms[Last Name]’. When the appreciation letter is semi-formal or casual, you can use ‘Hi [Name].’

Include what, why, and how details

Your appreciation letter should contain three separate paragraphs explaining what the letter is about, why you were impressed, and how the contribution benefited you. First, the purpose of the letter should be written, for example, the donation an individual may have made to your cause. Next, a paragraph on why you were impressed. For instance, you may be impressed by the large donation that the individual made.

In contrast, the third paragraph should explain how the contribution may have benefited you. For example, the donation made enabled you to build a much-needed facility. The length of these three paragraphs will be determined by how detailed you are.

Mention their unique qualities

You should mention the unique qualities that you have observed in the recipient. Be specific to show that you acknowledge the recipient’s unique traits. This shows the recipient that you are paying attention to their good deeds and their good attributes. It will also enhance the sincerity of your appreciation letter.

Be enthusiastic about their future

The conclusion of your appreciation letter should include a few sentences expressing your enthusiasm about the recipient’s possible future accomplishments and successes. This will boost the confidence of the recipient and their resolve to do better or be better.

Be personal and naturally sincere

Finally, the letter should end with the sender restating his/her sincere thanks to the recipient. This will emphasize the gratitude felt by the sender. The sender should then sign off and indicate his/her name. To add a personal touch, a sender can sign off with the phrase ‘thank you” or ‘thanks again’ instead of the more common phrase ‘sincerely.’


 You should personalize the appreciation letter to ensure it conveys your sincere gratitude to the recipient. You should consider whether writing an email would be appropriate or drafting a handwritten letter would be the best option. Answering which method will reach the recipient faster or which will influence the recipients’ perception of you is crucial. It is also important to consider the circumstances that prompted you to write the appreciation letter, such as a job interview, a donation made by the recipient, etc.

Dear Mrs. Michaels,

I want to relay my gratitude for the help you gave to my daughter, Nancy Levisohn. My daughter was your student when you were teaching math and science at Brighton High school. The extra effort you put into helping Nancy with her learning issues really paid off.

You see, my daughter ended going to aviation school and will be reporting for her first flight at JFK on April 10, 2020. This is partly due to your resilience and sheer determination to help my child, who has had learning disabilities her entire life. Nancy told me so much about you and how you would develop different ways to teach her a concept.

As a mother, I cannot begin to tell you what a great help you were. I was at my wit’s end on how I could help my daughter. I truly don’t know where my daughter or I would be without you.

I am ecstatic to hear about your promotion to Principle at a new school. The students there should count themselves lucky to have you. I want to restate my sincere thanks, and I hope that someday I can express my gratitude to you in person.

    How to Make your Letter Stand Out?

    It is important to ensure that your appreciation letter stands out to the recipient. This will help make it more memorable while ensuring it has the desired impact on the recipient.

    The following tips can help enable your appreciation letter to stand out:

    Write the letter as early as possible

    When showing gratitude to someone, it is important not to delay your show of appreciation. Appreciation should be shown as soon as the event, favor, gift, or action is performed. This will ensure that the person receiving the gratitude/thanks remembers your appreciation letter. The appropriate window to send an appreciation letter is within three days of a contribution being made.

    Explain your intention with gratitude

    A reason explaining why you are writing the appreciation letter should be provided. This will help remind the recipient who you are and what deed warranted the gratitude expressed in the letter.

    Keep the letter short and focused

    The appreciation letter should be brief and focused. A few paragraphs expressing your gratitude will suffice. A short letter will enable you to filter out unnecessary information.

    Be sincere and positive

    The appreciation letter should be written sincerely and positively.  Sincerity will ensure that a heartfelt message is conveyed, while positivity will boost the recipient’s confidence and self-esteem. Being sincere and positive will also help ensure the letter’s message leaves a lasting impression on the recipient.

    Edit till you perfect it

    Before sending the appreciation letter, you should proofread it to identify typos and grammatical errors. This will ensure that the draft sent to the recipient is edited to relative perfection. In addition, you may decide to have a trusted friend or colleague review the letter on your behalf so long as the information contained in the letter is not too sensitive or confidential.

    Consider the right format 

    The nature of the relationship between you and the recipient will inform the format used in writing and sending the letter.

    For example:

    Formal relationships often lead to using the business letter format, even when an email is sent.

    On the other hand, personalized appreciation cards, letters or notes are often suited for close relationships like friends, family, etc.


    An appreciation letter is a great and appropriate way to show your gratitude for deeds or contributions made by others. An appreciation letter should be simple, concise, and sincere. It should address the recipient directly and contain his/her specific qualities. This will help make the recipient feel acknowledged for his/her deeds/contributions.
