How to get started with ePost: The Digital Letter is now part of the universal service

Written by Die Schweizerische Post AG | Apr 9, 2026 7:30:00 AM

Business mail between analog and digital

Today, many companies use several communication channels in parallel: traditional mail, email and various portal solutions. This leads to fragmented processes and increased administrative effort. At the same time, requirements for security and traceability are rising. The Digital Letter creates a solution that connects both worlds – digital and physical.

What ePost enables

With ePost, you can send your business mail digitally. You send documents digitally – and your recipients receive them automatically, either digitally or as a physical letter.

Swiss Post handles delivery and automatically selects the best channel. For you, this means one consistent sending process, regardless of how your recipients can be reached.

How to get started

Getting started with ePost is simple and can be done step by step.

Start right away – no integration needed (SmartSend)

Many companies begin with the web solution SmartSend.

You can upload and send documents directly – no installation or integration required:

  • Register your company
  • Verify your address
  • Upload and send documents

This allows you to send your first items digitally within minutes – directly in your browser.

Integrate into existing systems (oneAPI)

For companies with higher volumes, ePost can be integrated directly into existing systems such as ERP or CRM via oneAPI.

This allows you to automate your sending processes:

  • Send documents directly from your systems
  • Manage shipments centrally
  • Track delivery status
