The content of the email should be sincere. I once sent an email to an author in China (2 1 1 associate professor of university) to ask for the source code of prose algorithm. Very sincere (the format is also very formal, including this salute and so on. ) and has also been used by the school (email! But the author felt really deep: I deduced all the formulas in detail in my paper and sent him an email attachment! As a result, the author replied to me quickly, not only sending me the source code, but also telling me his understanding of the algorithm. What suggestions can be studied! Because this article itself is a conference article (equivalent to Lite), the content is limited! At that time, the author's journal articles about the in-depth research and expansion of the algorithm had not been published, and then the author gave me a copy when the journal articles were formally accepted! The thing is, I also wrote an article through this source code and the original author's Gui Dan ce! Come to think of it, I am really grateful! Good man, good life! I also sent emails to other foreign authors and got the source code. But he only expressed his research needs and interests. He didn't send attachments as before, and he didn't reply this time ~

Respect other people's time and labor. Professors are usually very busy and receive a lot of emails every day. My tutor is not an academic, and receives at least dozens of emails every day (I can see the status of his emails when discussing this article, and often jump out for a few minutes to stamp), not to mention those awesome people in academia. Dig into it yourself? If you want your professor to see your email and reply, then the content is better, and it is not enough to talk about your understanding casually. And the tutor is probably just the guidance of your thesis and won't be impressed.
