GRTZ is an email client that syncs with your current email provider, but helps you spend less time composing and consuming email. GRTZ only allows you to send 87 character long subject lines, no body text. The more you and your colleagues/friends start using it, the less cluttered your inbox becomes. You'll spend less time reading long emails and less time composing them. Sending and receiving GRTZ, might just solve the inbox problem for many busy entrepreneurs.
