Digital communication has become the standard, making secure document delivery more important than ever. Public authorities, businesses, and private senders need to share sensitive information without the risk of it falling into the wrong hands.

e-Boks is a secure digital mailbox that allows you to receive official documents from companies easily and safely. But how does it work in practice, and why is it important to use a secure solution like e-Boks?

In this guide, we will go through why secure document delivery is crucial, how your business can get started, and how you can securely send letters to a recipient in e-Boks.

When and why

When sending sensitive information – such as contracts, legal documents, or personal data – security and credibility are essential. Here are some of the key reasons to use a secure digital solution like e-Boks:

  • Protection against data breaches – Emails and traditional mail can be intercepted by unauthorized parties. e-Boks uses strong encryption so that only the recipient can access the content.
  • Legal validity – When sending documents via e-Boks, you can be sure that the delivery is legally binding, as the recipient's access can be documented.
  • Compliance with GDPR and legislation – e-Boks is a secure solution that complies with GDPR, ensuring that personal data is handled correctly.
  • Efficiency and documentation – e-Boks provides delivery confirmation, so you can always see when the recipient has opened the letter.

Secure document delivery is not just about convenience but also about data protection, legal security, and efficiency.

How to get started?

To securely send letters to a recipient in e-Boks, you must ensure that you have access to an e-Boks business solution or another integrated platform such as Addo Sign, which supports digital mail delivery to recipients in e-Boks.

Who can send mail to e-Boks?

Both public authorities and private companies can send letters to citizens and businesses via e-Boks. If your company does not yet have an agreement with e-Boks, you can start by:

  1. Checking if your company already has an agreement with e-Boks or Digital Post.
  2. Setting up a business agreement with e-Boks or through a digital mail solution that supports e-Boks, such as Addo Sign.
  3. Getting access to integration options – either via an API solution or a platform that offers e-Boks integration like Addo Sign.

e-Boks offers a direct solution for businesses and authorities to send documents securely. However, it often requires technical integration or the use of a third-party platform.
