Hi,

Im hoping to find a concept of a business which should send large quantities
(more then 10k per day) of phisical mail (not digital)in europe.
What I look for is a business located in one european country that
ships to other countries within europe.
The answer should be "a type of business" I will continue the search
myself from that point.

Thank you

There are such businesses.  I receive US company reports to my address
in Germany that are mailed from somewhere in Europe, perhaps Holland. 
Unfortunately, I don't have any at hand just now.

Thanks myoarin
Let me know if you come up with one

I will let you know.  It may take a week or two or longer before the
annual reports start rolling in.
