Swiss Post's international mail service remains one of the best in terms of performance. Independent measurements show that Swiss Post yet again figured among the fastest postal companies in Europe in 2006. Priority letters from Europe to Switzerland and vice versa took an average 2.0 days to reach their destination. Delivery times are thus lower than those of the European average as a whole.

In 2006, Swiss Post was again able to improve somewhat on the already high quality of its international letter-post service. In tests conducted by the International Post Corporation (IPC), the company once again achieved a relatively high ranking, thus living up to its reputation as one of the fastest and most reliable postal operators in Europe. Priority letters mailed from Europe to Switzerland in 2006 took two days on average to reach their destination. In 2005, the average delivery time was 2.1 days. Generally, priority mail from Switzerland to other European destinations also reached the intended recipient within only two days of posting. Swiss Post International (SPI), the international arm of Swiss Post, thus beat the average delivery time for all the countries surveyed of 2.1 days.

29 European nations participate in the IPC's international measurement system, known as the UNEX study. The IPC determines international delivery times by introducing around 350,000 test letters to international mail flows. The involvement of external, independent measurement contractors guarantees the validity of the results.

Last year's delivery times for Switzerland were published in February 2007. Here too, Swiss Post received top marks: 98 out of 100 letters were delivered on time (A mail: 98.0%; B mail: 98.3%). Delivery times for parcels were of an equally high standard (PostPac Priority: 97.3%, PostPac Economy: 97.6%).
