A whole new email experience for enterprise communication

Email at its best

VNCmail offers all relevant mail features such as inbox, folders, filters, signatures, spam filters – in short, everything you are already familiar with from your everyday communication. And the clean VNCmail design makes communication fast and efficient.

VNCmail is more than just a common groupware tool. It can be integrated with several VNCproducts to vastly extend its range of functionalities. Your email functionalities can for example be connected to VNCsafe, a file sync & share product, to attach files directly to emails. Of course any email attachment can be stored in VNCsafe, too.

Furthermore, VNCmail has optional Blockchain technology to ensure the digital provenance of your emails by attaching a seal to each email in the form of a QR code that can be verified.

VNCmail comes with the powerful VNCcalendar extension which manages not only private appointments, but enables professional group calendaring functions such as sharing and invitations. You can share your complete calendar to see each other’s availability or, for example, birthdays and holidays in teams or the company.

VNCcontacts is also included in VNCmail and offers a powerful contact management tool where users not only can store any kind of contact with lots of information, but also can sort the contacts in predefined or individually created lists.

Many solutions offer merely limited branding options. We enable our customers to strengthen their corporate identity with very granular design options, matching their needs. Instead of just pinning a company logo in the top left corner, we can adapt the complete user interface of VNCmail according to the company CD/CI and we can also customize functionalities to industries or user groups.

VNCmail is available as Web Client, Desktop Client and App so you can stay up to date wherever you are. The clear structure with its folders and filters make navigation easy and transparent.

VNCmail comes with offline functionalities, thanks to the fast sync between all devices our users are always up to date.
