Thank you, outofredink !
That was very helpful, especially since one of your fields is the same as my own. I have already started my SoP and am giving it all of my attention as well as having it read over by many professors at my current undergrad program. I wasn't intending for these proposed e-mails to take the place of a great SoP, recs, and writing sample. I just thought perhaps it would be good to get my name into consideration before the apps started rolling in. But, like you, I didn't know if prospective professors would find that appealing in a student or simply annoying!
Please let me know how your applications fare, I am especially interested to learn about UPenn (a program I would very much like to attend).
