Hybrid Letter – Ready for the Future with ePost
Swiss Post is taking a new path with the hybrid letter: traditional mail goes digital. With ePost, companies and public authorities can already send letters digitally – and recipients decide whether to receive them digitally or in printed form.

How does the hybrid letter work?
Digital submission
The sender submits the letter via ePost – using SmartSend in the web client or via an API integration.
Address check
ePost checks how the recipient prefers to receive the letter.
Digital delivery
The letter is delivered digitally via the ePost app or to a connected customer portal.

What is a digital letter?
A digital letter is more than just a PDF.
It can contain structured information that can be processed directly – such as invoices, contracts or interactive forms. Delivery is secure, encrypted and sent precisely to the intended recipient via ePost.

Invoices

Contracts

Interactive forms
The ePost App – Switzerland’s official digital mailbox
With the free ePost app, you receive digital letters at your physical address – but in digital form. Your letters are secure, always accessible, and easy to archive.
Optionally, you can activate the scanning service (paid): your physical mail is forwarded to a scanning centre, digitised, and delivered to you as a digital letter. This means all your mail becomes digitally accessible – regardless of the sender.

Advanced delivery options for senders
Senders can offer recipients dedicated digital mailboxes – for example, through customer portals like BE-ePost from the Canton of Bern. These mailboxes are “Secured by ePost” and meet the highest standards of security and data protection. Recipients can also use the ePost app to receive all their digital mail in one central location – no matter who the sender is.
Who is the hybrid letter for?
Public authorities
The hybrid letter enables modern administration – digital for those who prefer it, physical for those who need it.
Businesses
Communicate more efficiently – digitally, on paper, or both.
Private individuals
Receive your mail securely in the ePost app – or continue to get it in your physical mailbox.
