Dear EditorinChief,

How are you doing? 
Sorry to bother. I just wanted to let you know that i am going to send you a very important paper this week. My academic career is depending to this paper. In our department after 2 years, we have to defend our long paper in-front of the 3 committee members. I am working on that paper for over 8 months now. I am going to try to send it to you as soon as possible. 
This paper is everything.

Just wanted to check to see if you are available this week.

Thanks again,
Best,
Sahar
