Further to the change we announced in November 2015 allowing Polymer outers to overhang by up to 30mm when posted as Machinable Large Letters, we are pleased to inform you that due to additional upgrades to our Large Letter automation machines, and some recent product specification reviews, we are making the following beneficial changes that will be implemented on 3 October 2016.

• You will be able to send Machinable Large Letters using the Unwrapped spec and benefit from the lower prices of OCR or Mailmark
•  We will no longer apply the white 'route tag' labels giving you greater flexibility when designing your mail piece.
