Test items are an important instrument for measuring transit times and checking the delivery quality of postal items. The Spectos Lettershop is set up to produce test mailings for transit time measurements. Benefit from an easy and convenient provision of your test consignments with our in-house lettershop.
The test letters to be sent are physically prefabricated by our in-house Spectos Lettershop. We handle all preparatory work for your transit time measurement: We print, envelope and bundle your test consignments per feeder and day of dispatch. In order to ensure that real mail and test items cannot be distinguished, name and address of the corporate customer are printed as sender in the address window of the test letters. If necessary, individual envelopes from senders will be used.
To rule out measurement errors, all test items are thoroughly checked for correctness of the data before dispatch. The Spectos Lettershop delivers then the ready-to-send test items to the respective customers of the letter service as feed-in point. From this moment on, your transit time measurement begins. The test letters cannot be distinguished from real mail items after induction into the mail stream. The test consignments are transported in the same way as the real consignments.
Transit time measurements make it possible to check service quality and derive quality-enhancing measures. Furthermore, they serve as proof of compliance with applicable European standards for letter delivery times in accordance with EN 13850 and EN 14534.
