How to Write a Confirmation Letter: A Comprehensive Guide (2023)

A confirmation letter serves the purpose of affirming that something or someone has been accepted successfully, as well as confirming attendance to a specific event, celebration, presentation, concert, or activity that one has been invited to. The writing of confirmation letters should follow a certain structure, as there are some differentiations among them. In this guide, we will provide you with more information on how to write a confirmation letter.

What is a Confirmation Letter?

A confirmation letter is a letter that aims to confirm something specific. Some confirmation letters are intended to affirm that an employee has been accepted for a vacant job position, while others are used for educational purposes, confirming a student's participation in a certain activity. In general, confirmation letters are used for various reasons, and their content may vary accordingly. However, they typically involve an affirmation, as otherwise, it would be a rejection letter.

Structure of a Confirmation Letter

While the content of a confirmation letter may vary, the general structure remains practically unchanged and follows the writing formalities of other types of letters, such as:

1. Membrete: In the case of a confirmation originating from a business or institution, the letterhead is practically obligatory, as it represents, along with the signature of the writer, the decision of a company.

2. Date: The date in the header simply represents the moment when the letter is being written. It consists of the day, place, and year.

3. Sender's Name: Depending on the type of confirmation letter, the name may include the position as well. If confirming an employee's entry into an organization, the position they will assume should be added.

4. Body Text: There is no general way to write the body of a confirmation letter. It is recommended to start with a cordial greeting and then proceed with the confirmation. If additional information needs to be added, multiple paragraphs can be written consecutively.

5. Closing: The closing is a formal and unchanging element of these letters. It can include an additional invitation or congratulations.

6. Signature: The signature lends credibility to the letter, serving as proof that it has been written by someone with sufficient authority to confirm.

Types of Confirmation Letters

There are three main types of confirmation letters, which differ in the content of the body and the information included in the text. These are:

1. Employment Confirmation Letter: Used to confirm the acceptance of someone into a position or role within a company. These letters often include details about the tasks the employee will perform, specific instructions, the start date of employment, and sometimes an invitation to a welcome event.

2. Academic Confirmation Letter: Universities frequently use this type of letter to confirm the acceptance of an applicant. They are also requested to provide support for students who have been confirmed for internships in a work environment.

3. Activity Confirmation Letter: Although these letters have become less common in recent times, they serve a purely formal purpose. They affirm that the recipient will attend an event or celebration to which they have been invited, usually due to their significant role in its development.

How to Write a Confirmation Letter

The most relevant element in this type of letter is the word "confirm" and "confirmation," as they express the action of responding to a received invitation. Here are some recommended instructions for writing a confirmation letter:

  1. Be very cordial. Confirmations are usually good news and reasons for celebration, so use appropriate words without exaggeration.

  2. Formality is essential in this type of letter due to its protocolar nature.

  3. The body text should be direct and concise, without being overly lengthy.

  4. Inform about the type of confirmation. For example, "...this letter is to confirm my presence at your company's anniversary celebration."

  5. Close with a cordial farewell.

  6. The closing can be a congratulation or an invitation to celebrate the confirmation.

  7. Do not forget to include your signature at the end.
