Priority and Economy letters
You can send standard international letters to all countries at two different delivery speeds. When you want to send letter items affordably and there is no rush, choose the Economy letter. Priority letters are delivered all over the world with fast connections.
Economy letters leave Finland within a week of mailing. The items are delivered to the recipients based on the delivery times in the destination country. You can send an Economy letter or card weighing less than 20 g using a domestic no-value indicator stamp.
Priority letters are delivered all over the world the weekday following the mailing. Use an international no-value indicator stamp when sending a Priority letter or postcard weighing less than 20 g from Finland to abroad.
Follow these steps:
Attach the stamp to the top right-hand corner and remember to add the name of the country to the address as instructed.
Remember to always mark “Priority” or “Economy” on the envelope, either with a label or by writing.
Drop off the item in a mailbox. You can also bring the letter to any Posti service point that offers all of Posti's services (including Letter Services). See all service points.
Note! If the letter contains goods and you are sending it outside of the EU, please read the instructions on how to register the letter.

What does the postal insurance cover?
Postal Insurance covers damage up to the insured value. If any damage occurs, it must be substantiated. In case of damages, we recommend keeping a receipt, for example, showing the value of the contents of the item.
Postal insurance only covers direct damage and does not cover, for example, antique, collectible or sentimental value. If your item has such value, we recommend checking out the insurance policies offered by insurance companies.
