Receiving IncaMail messages
In principle, anyone with an e-mail address can receive “confidential”, “personal” and “registered” IncaMail messages. Business customers receive IncaMail messages signed and already decrypted. All other recipients receive an e-mail from Swiss Post containing a “Read” button. To open the message on any device, be it your desktop or a mobile device, simply click on the button.
Note: unregistered recipients of a “confidential” IncaMail message have the option of registering. Registration and a one-off approval are required in order to receive “personal” and “registered” IncaMail messages.
Mailing IncaMail messages
There are three ways of sending secure IncaMail messages:
- via the IncaMail web interface (for private users and teams);
- via add-ins with current e-mail clients such as Outlook, Office 365 etc. (organizations with e-mail infrastructure connected directly to IncaMail);
- via business software with IncaMail integration, e.g. for mailing payslips
