Spring Global Mail: international measurement system

On behalf of the international postal service provider Spring Quotas had been monitoring the quality of its global logistics network for several years. Every year, thousands of test mailings in different formats were sent from 25 Spring locations on different continents.

The most important distribution channels were continuously checked and tested with the support of several hundred panelists that acted as receivers of test mail in more than 40 countries around the world. The delivery time and the condition of the mailings received were the main elements that were measured in this study. The evaluation was supplemented by ad hoc tests.
