I sent in a ticket saying:
This might seem silly, but I am sentimental. When i got Emperor last year in October, I kept my in game mail announcing my Emperor achievement because it meant a lot to me. Today that mail got deleted on accident and I'm so sad

is it possible for you to replace my mail? I know its a little annoying but please it would mean the world to me to have that mail back!
I got this in response:
