Mailer companies’ tools

Mailer companies' tools, electronic ordering channels, are available on the Posti Service Portal. All of the ordering channels are logged into using the same user codes. User codes can be obtained from your company's administrator. If your company does not yet have an administrator, you can order user codes here.

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. In exceptional circumstances,  a printed mailing list serves as a backup system.

Please note! When using Mailing Desktop (PTP) or Kontakti, an electronic mailing list will be automatically prepared for your mailing batch so that you do not have to fill it out separately.

Batch sorting and bundling

Batch sorting, or bundling, and unitizing are necessary for large mailing batches. Postal items are sorted into postal code order and bundled according to the instructions provided in the Guide for Batch-Sorted Postal Items (Addressing, Bundling and Loading into Transport Units). An additional handling fee may be charged for non-compliance with the instructions.

Below, we have gathered instructions on key matters related to batch sorting. If you use the Sorting Service, you will have the correct information automatically.

  1. Bundling order
  2. Bundle label markings
  3. Delivery control data for shipments
  4. Transport units and unitizing levels

You can use the RCC2 control label application to print transport unit container labels with bar codes. The unitizing levels are specified in the Guide for Batch-Sorted Postal Items (Addressing, Bundling and Loading into Transport Units). In unclear situations, please contact our customer service.

Machine processing for smoother handling

When you are wondering what kind of postal items without a plastic wrapping can be sent as a machine-sortable item or when you are planning the appearance of an envelope, please follow Posti's service-specific requirements for machine processing. Machine-sortable items move quickly through the various stages of processing and are delivered to the recipient on schedule and in the correct form.

See the dimensions and weights of machine-sortable items, instructions on how to mark and place the recipient's address information and other matters that should be taken into account in the Guide to machine-sortable items.

A bundle properly tied using non-stretch bands guarantees that it withstands machine sorting and is in compliance with the conditions for batch sorting. Items are bundled based on their postal codes and in alphabetical order in accordance with the delivery address.
