The position of the address is an import part of your letter, we not only need to extract the address for certain post types, but your letters are posted in windowed envelopes and therefor need to be positioned correctly for the delivery service. Sometimes it may only be a subtle movement which is why we introduced ‘nudging’. This feature allows you to move the position of the 1^st page slightly in any direction. The measurement is in millimetres.  

A positive number in the “Right” field will move the 1^st page to the right. A negative number will move the 1^st page left.  

A positive number in the “Top” field will move the 1^st page to down. A negative number will move the 1^st page up.
