Email is such an indispensible tool nowadays. As opposed to the late nineties, where email started to gain ground, we are nowadays dealing with much more messages, message categories (including spam and bacn), as well as social email conventions (e.g., when should you cc someone?).

IBM did so, back in 2003. They called it ReMail. I’m still waiting for the launch.
