Choose the most suitable delivery service
When you send large batches of letters yourself or through your mailer, the best solution for you is a machine-sortable Standard letter or an Economy or Priority letter sent using a mailing list. You can also choose the Economy or Priority service level for a Standard letter according to your needs.
The Standard letter allows for substantial savings in postage fees if you mail a lot of items
The machine-sortable and standard-sized Standard letter is the most affordable way to send large letter volumes. The Standard letter is suitable for professional mailing. In order to send Standard letters, your organization or mailer must be using the Posti Sorting Service. A Posti 2D code provided by the Sorting Service must also be added to each Standard letter item.
