An affordable Standard letter is suitable for mechanical sorting

When your letter item is suitable for Posti's mechanical handling, the Standard letter is the most affordable option. Machine-sortable items move quickly through the various stages of processing and are delivered to the recipient on schedule and in the correct form. In addition to optical reading requirements, suitability for machine handling also sets some dimension, shape, material, color and content requirements for the letter item.

If the address is incorrect or obsolete, the Standard letter will go through address clarification and it will be delivered to the recipient's valid mail address without extra charge. If the correct address cannot be determined, the letter will be returned to you.
