We have no hidden interests in your data and do everything to ensure that private matters remain private.

Our web-mail client

Whether you use a PC, tablet computer, or smartphone: our web-mail client is easy and comfortable to use with any device. features an inbox interface that uses tabs to organize the content and that can be customized and trained by the user so that e-mails are automatically moved into sub-folders for private, business, social media, or shopping-related messages.

Experience tells us that the use of encryption is only successful if it is both secure and easy to use without hassle. Our web-mail client provides encryption for the sending and receiving of e-mails without requiring the installation of any extra software. Encryption becomes an automatic part of the process - even when you use other devices away from home.
