Hi,
I want to ask :what is the best way to add a little note after I write a formal email to my professor?
For example I want to add this sentence, because I couldn’t find away to add it through the paragraph
My Note is : yes I have written X to the instructor and been waiting his response.
At the end, leave a blank line and then write
PS - Yes, I have written X to the instructor and I am waiting for his response.
Best wishes, Clive
