TouchMail
TouchMail is an email application developed for Microsoft Windows, launched on April 17, 2013 at the DEMO Mobile Conference in San Francisco.
TouchMail was developed by a Seattle-based startup founded in 2012 by former Microsoft employees Matthew Carlson and Alex Frank as an e-mail client designed for touch input. It runs using the Metro-style user interface introduced in Windows 8 and currently functions on both Windows 8.1 and Windows 10. The emails in the client can be color-coded with zoom out features to view more messages. The application integrates work and social messaging using visual and touch capabilities of computing devices.
