Translation of Kundenbetreuer

I would rather like that you write through the messaging system on this site and not to my private email address. All the info is gathered here online and I would like to keep is this way. It is nothing personal.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
Well, now that we're friends, I am very happy to send you images. I would be happy if we can keep the contact for a long time. May I ask a questions: is Emily your real name or just an avatar name?
