The link in the notifications lets you do more than change the delivery date and address. If you will not be at home during the hour given for delivery, you can ask for the parcel to be put in a safe place at the original address. This may be a post box or a space behind a large object. Direction to a safe place is only possible for non-COD and non-time-guaranteed packages. Please note that this constitutes delivery without signature, because the package has not been handed over personally to anyone. Only the recipient can request redirection to a safe place, via the link in the notification. It cannot be entered via customer service. If you choose this option, you cannot withdraw it later for this consignment.
