You have to print out the address-thingy though (which also lets them know what you're sending back).
And guess what, it's all on their website
It's great, order multiple sizes and colours and styles.. Keep what you want and send the rest back and only pay for what you kept.
The others do it that way but with Zalando you usually have to log on and let them know what you return - then you also get the label done.
But maybe they've changed it as I haven't done business with them for ages.
Step 1 is to Log in and let them know what items in the order you will be returning. Step 2 is to use the label sent with the order and give the package to the post office.
Sending items back: Use the original bag/box.
Log in at Zalando.
Go to 'Mein Konto' then to 'Artikel zurückschicken' -> 'Artikel jetzt zurückschicken'.
Chose the 'Bestellung' you want to send items back from.
'Artikel aus dieser Sendung zurückschicken'.
Tick the box of the item you want to send back. Confirm.
Put the item/s back in the bag/box.
Stick the return label on (which you find on the bill in the bag/box) and bring it to the post office.
I guess you know you can change that.
Right mouse-click on message - "markieren" (mark?) - junk .... no junk ... what ever you want it to be, there is a spam-filter you can set as well ....
You can also just put the address of zalando in your addresses and thunderbird will consider zalando a friend
