Highly Sensitive Tax Bills Mailed for Council Client

We managed highly sensitive tax bills for a council, ensuring the integrity of each mailing was always 100%.

Transactional direct mail tax bills are generated for our client from a custom system, and they supply them to WDM as print-ready PDFs. Tax bill data has extreme sensitivity, so the integrity of each mailing always has to be 100%. 

Our solution

In the past, this meant enclosing letters with varying numbers of pages by hand or counting every envelope to ensure there hadn’t been any doubles fed through the inserting machine if the letters were only a single page. We created an automated process that saves the PDF to a watched folder. The PDFs are analysed to work out how many pages are in each letter, and a 2D barcode is added, then they are sent to the print queue. The 2D barcode is read using a camera on one of WDM’s inserting machines and the correct number of pages is folded and inserted into the envelope. The number of printed pages and envelopes required is automatically added to a report which is used to manage the stock and generate the monthly invoice.

As an added extra, WDM were able to determine if there was more than one letter being sent to the same address, and put those into the same envelope, which meant fewer envelopes being used and savings created on postage as well.

The outcome

This case study highlights WDM’s ability to guarantee two, three, and even four-way mail-matching — the ability to ensure multiple personalised elements within each direct mail pack are completely accurate.
