Public agencies want to send your post digitally instead of on paper. There are two providers of digital mailboxes, e-Boks and Digipost. A digital mailbox is a secure digital solution for receiving and storing important post from public agencies. Letters concerning decisions, health information and other sensitive information cannot be sent by normal email. Digital mailboxes are free to set up and use, and let you store letters for as long as you want. You will be notified by text message or email when you receive important post from an agency.
