Even letters that don't arrive are valuable!

Every letter sent incurs costs (mainly because of the high postage costs)
and it is therefore very important to know the undeliverable letters
and the reasons for the undeliverable nature.
For the returns of your mailing we will provide you with postal boxes
or promotional postal codes - free of charge!
This means that we can report every undeliverable letter
and you can update your address details.
This allows you to save costs in advance on future projects.
