Which section of the letter restates the main point and may include a call to action?

The conclusion of a letter serves as a critical component where the main point is restated, reinforcing the purpose of the communication. This section often summarizes the key messages that have been conveyed throughout the letter, ensuring that the recipient clearly understands the central theme. Additionally, the conclusion may include a call to action, prompting the recipient to take specific steps, such as replying, considering an offer, or engaging further on the topic discussed. This creates a clear and impactful ending, distinguishing it from other parts of the letter, such as the introduction, which sets the stage, and the body, which provides detailed information and arguments.
