IncaMail is the email service of the Swiss mail service for the electronic exchange of protected information or documents.

Among others, this service covers the area of E-government. As such it enables the sending of digitally registered letters to courts. The letters sent this way are definitively recognised by Eidgenössisches Justiz- und Polizeidepartement (EJPD) [Swiss department of justice and the police].

Via the "IncaMail Connector", this service can be integrated as additional, alternative encryption technology.
