The subject of the contact tutor email should include your name first, so that the tutor can quickly identify the sender. Next, clearly express your purpose, such as consulting, asking for a meeting or seeking guidance. Finally, if you have specific requirements or questions, you can simply mention them in the title. For example, consult the research direction by name or ask for a meeting by name. Such an email subject can let the tutor know your intention quickly and improve the response rate.
