First, the subject of the email.
You don't need to write your own name in the subject of the email. The name is set in the mailbox system settings, and the actual address will be replaced when it is sent, so there is no need to rewrite it in the subject.
Second, the title.
Address is very important. The safest way to start is to use "Dear Professor XX" (XX is the surname). In this way, whether a professor is a doctor or not will not be considered, and calling a female professor "lady" or "madam" will not appear sexist.
Third, introduce yourself at the beginning and show your purpose.
Generally, I introduce myself briefly at the beginning, expressing my interest in his research and giving some affirmation to the author's achievements. It is very important to clarify the purpose of the email at the beginning, so as to better lead out the main content of the email.
Fourth, ask questions or requirements.
It is best to be concise and clear, and it is best if the questions are concise and clear. If you can't get to the topic soon, the other party will lose interest in reading the email.
The conclusion of a verb (the abbreviation of verb).
Before ending the email, thank the recipient again and add some polite words at the end, which will make the other party more active and willing to take action.
