If the Sorting Service is not working properly, please wait a moment and try again. If this does not help, check your network connection. Kindly also check that the product information or other parameters you have provided were entered correctly. Erroneous information may cause disruptions.

If the disruption lasts for a long time, send an error message by email to lajittelupalvelu@posti.com and we will start fixing the problem immediately. The email is monitored during office hours on weekdays. If necessary, our specialists will contact you.

If your mailing schedule is flexible, please wait for the system to start working. If you cannot delay the mailing, follow these instructions:

  1. Keep preparing the mailing batch with the help of the Guide for Batch-Sorted Postal Items or service-specific mailing instructions for letters. - Standard Letter Pro mailing batches are unitized in four directions (4k) according to Guide for Batch-Sorted Items: Loading of items into transport units, page 21.

  2. Use the electronic mailing list – Magazines: continue filling out the mailing list created with PTP.  – Customer Direct: continue the mailing list created in advance for the mailing batch. If you do not have one, create a new one. – Priority Letter, Economy Letter or Priority Standard Letter: register the items on the mailing list. – Standard Letter Pro services: we will contact you and issue separate instructions.  

  3. Note that the Sorting Service was out of use in the Additional information for mailing list handlers and Posti’s reception field. This ensures that we will not charge unnecessary additional service fees from you.

  4. Also remember to mark the mailing list as completed and attach cover letters to the mailing batch.

  5. Drop off the shipment lots at the posting place.

Mailing Desktop

Mailing Desktop (PTP) is a tool that is intended for regular and repeated mailing of publications and Home Direct items. PTP is used to make annual and advance orders for deliveries and mailing plans related to these. Based on the information submitted, an electronic mailing list will be generated, and the mailer company can print the needed mailing instructions and documents.

Sorting Service ensures quality

The Sorting Service provides automated and batch-specific support for preparatory work in mailing. It ensures the delivery of items to their destination, reduces mailing quality defects and makes the delivery chain more transparent. Sorting Service produces 2D codes and 4-state codes that are used on letter, publication and DM items.

Batch sorting and bundling

Batch sorting, or bundling, and unitizing are necessary for large mailing batches. Publications are normally always mailed in bundles. The Guide for Batch-Sorted Postal Items (Addressing, Bundling and Unitizing) is intended to be used by large-volume senders as well as printing and mailing companies to help with preparing mailing batches for mailing.

Machine processing for smoother handling

When preparing the items, find out and bear in mind the service-specific requirements of Posti’s mechanical handling, such as measure and weight limits and the placement requirements of 2D codes, 4-state codes and address information. Machine-sortable items move quickly through the various stages of processing and are delivered to the recipient on schedule and in the correct form.

Electronic mailing list

Posti contract customers can use the electronic mailing list to submit information about letter, direct marketing and publication items to Posti. The mailing list serves as the basis for invoicing.When using Mailing Desktop (PTP) or Kontakti, an electronic mailing list will be automatically prepared for your mailing batch.

Kontakti – a tool for direct marketing

Kontakti is a diverse online tool for planning and implementing direct marketing. You can manage all of the planning of Home Direct deliveries as well the purchase and mailing chain using Kontakti.Home Direct and Home Direct Premium items are ordered through Kontakti or PTP. Kontakti is particularly well-suited for campaign and small item mailing, whereas PTP is particularly well-suited for regular and repeated mailing.
