If you are writing an email to ask me to do something for you, you might want to include the following in your email:
(a) Dear Professor Wang or Dr. Wang (or some appropriate way to address me);
Wang (not You) is my family name. Do not address me as Ms./Miss/Mrs./Mr. or any other kind of gendered addresses--you will not get a response. Also, you cannot imagine how many times I was addressed as Mr. Wang or, in Chinese, 王兄.
(b) Some pleasantries (optional);
(c) Who you are and where we (may) have met (if you suspect I may not know you well or at all), or any good news or pleasant things you've encountered (if you suspect I know you well, optional);
(d) The nature of your request (new paragraph, if possible);
(e) When do you need the task to be done from me (bold the date, if possible);
(f) When do you need an email response from me informing you whether I can do the task (if your tasks is urgent, or if the task you request need longer to complete, and you'd like to know whether I can do it earlier; bold the date, if possible);
(h) Your sign-off.
If you are not in a rush, unless you are truly fine with me taking my time, please do not just say "take your time". I take words at face value. You can say things like "I'm not in a rush, but I expect to get around to revising this in 2 months."
If you are writing on behalf of an academic institution with resources, I would appreciate it if you compensate me for my labor, especially if you are inviting me for diversity, equity, and inclusion (DEI) related activities, or if you are inviting me because there are not that many people in academia who look like me (read more on the so-called "minority tax"). Also, as a U.S. Resident Alien in H1B status, I cannot receive honoraria outside of my approved employment Georgetown University.
I might say no, but it doesn't hurt to ask.
If you are writing an email to tell me how awesome I am, please just send it in whatever form you like! It is always a delight to receive such an email. I may not respond though (due to the sheer number of emails), but please know that I love receiving those emails.
Please also note that I write in an assertive and direct way. If you are startled to receive such an email from me, but not from a Chinese/white man, you may want to take the implicit bias test.
