Changes to letter services

On this page you can find information on the changes to letter services that will take effect over several stages in 2017. There will be changes in areas such as the delivery speeds of services. This page will be updated as we progress with the changes.

Changes to prices of domestic Economy Letters on June 1, 2017

The change in the price of the domestic Economy Letters only applies to domestic Economy letters sent from a mailing list (product number 12909). This service’s item price increases but the kilogram price remains the same. You can check price lists online at

- The change in prices does not affect the list prices of Economy Standard Letters (product numbers 12910 and 17009), Posti Pre-Paid Envelope prices or Economy letters paid for with franking machines. The prices of Pricing service letters or letters sent abroad will also remain the same.

Changes to delivery speeds as of March 6, 2017

The delivery speed of Economy letters will be slowed down by one weekday as of March 6, 2017. Following this change, an Economy letter will usually reach its recipient on the third weekday following the posting day. For example, if you mail an Economy letter on Wednesday, it will usually be delivered to the recipient on Monday. You can expedite the delivery speed of Economy letters by using the Sorting Service if the batch size or partial batch size is at least 25,000 letters. The mailer company must sign an agreement with Posti regarding the use of the Sorting Service. When your mailer company uses the service, your letters will usually be delivered on the second weekday following the posting day.
