Which piece of information is NOT typically included in the subject line of a letter?

The information that is typically not included in the subject line of a letter is the recipient's job title. The subject line serves primarily to provide a concise summary of the main topic of the letter, often focusing on the patient's key identifiers, such as their name, age, or date of birth.

Including the patient's name is essential for clarity and identification, allowing the recipient to quickly recognize the subject matter. The patient's age may also be relevant, particularly in a medical or clinical context where age-related considerations play a role in treatment. Furthermore, the patient’s date of birth is crucial for accurate identification and for differentiating between patients with similar names.

In contrast, the recipient's job title is typically not a priority in conveying the main purpose of the letter. The content of the letter itself would provide context for the recipient's role, making it unnecessary to include their title in the subject line. Thus, focusing on key patient information in the subject line enhances communication effectiveness while keeping it relevant and succinct.
