How do I get the email address of the German Post Office for investigation?

I wanted to know where the postcard I sent to my girlfriend on vacation was! I called and was given the address: " www.deutschepost.de/nachforschung "! I was just about to send the email, but it said: " Please correct the email recipient entry." Who can tell me what the correct email address is? Thanks, have…

Do you still write personal letters and postcards? And do you keep the ones you receive?

Do you still send birthday or holiday greetings, or even just private personal messages, by letter or card? I find that much more personal (just because of the handwriting), but what do you think? Do you, like me, have an archive of the letters and cards you have received?
