I don't know if she's getting personal one on one email. I just happened to notice this one as the page was left open. It was a cc to a bunch of addresses.
As far as counting time, probably done the same way an elder explained to me how he counted his letter writing time years ago. Keep track of the time put into writing one letter, duplicate it and send it out. One letter written, one half hour, 50 copies x .5 hours = 25 hours .... He was legally blind, so he would print the letters in a large font and stamp "free material for the blind" to avoid paying postage.
