According to Email Tip #3, what three things should be included in a direct subject line when emailing a teacher?

Including your name, class period, and topic in the subject line of an email to a teacher is essential for several reasons. Firstly, the teacher needs to quickly identify who the email is from, and your name provides personal context, facilitating a connection. Secondly, knowing your class period allows the teacher to categorize the email with the right group of students, making their response more efficient. Lastly, specifying the topic gives clear insight into the purpose of your email at a glance, allowing the teacher to prioritize and address your concerns appropriately. This structured approach enhances clarity and respectfulness in communication, which is valuable in an educational setting.
