A whole new experience in enterprise communication


Mail is dead! Messengers and Social Collaboration tools are the new way to share ideas and get stuff done.



We still believe in the value of email. But we need to modernize email. And we need to integrate with other communication channels like social media, messenger etc.

This is exactly the reason we invested tremendous resources in VNCmail, which is available as a VNCuxf based desktop client, responsive web client as well as an app for Android and iOS.

VNCmail can be connected to different backend services as we have an abstract Restful API to communicate with e.g. Zimbra, which we consider still the leading open source groupware on the market.

VNCmail follows the Google material design standards and thus looks and feels like Google Inbox. Users get familiar with VNCmail instantaneously without any need to train users.
