I have sent mail 1st Class
but its showing as 2nd Class

This is due to your mailing item having an international destination.


All international mail is handled in the same way, not differentiated by 1st or 2nd class. This is why its showing as 2nd class despite being in your 1st class postbox. It defaults to showing as 2nd class as this is how we need to handle your item in production. Rest assured this will not impact the timescale of the delivery.

Failure Message due to Invalid page count.

This error shows when the PDF uploaded cannot be split according to page split number selected.


For example, if the PDF uploaded has 13 pages but you have selected a postbox that splits pages by 2.


The system recognises this error allowing you to then either amend the PDF or select a single page split.
