Product information


The Digital Letter facilitates the sending of communications that must be physically delivered to one or multiple recipients, managed fully online through our website.

With our Digital Letter, you can manage your shipments at any time, from anywhere:

  • Easier than ever: make your shipments directly from your computer, at any time without queueing in our Post Offices.
  • We do it for you: save printing, envelope and paper costs.
  • Share the tracking of the certified letter with whoever needs it.

You can choose whether your letter is ordinary or certified, both nationally and internationally.

For national certified letters, you can also add the  Electronic Proof of Delivery (EPD) service.

Also, during the process, you can decide if the letter should be printed in black and white (B/W) or colour.
