Managing email isn’t just about wading through incoming messages, writing replies, filing messages into different folder, but it’s also about managing the expectations of the people who are writing to you. Courteous.ly, a new research project by Georgia Tech School of Interactive Computing professor Eric Gilbert wants to make it easier for you to manage these expectations by giving those who want to email you a better idea of what your inbox looks like right now and when they can likely expect a response. The service, which currently only works with Gmail, regularly scans your inbox for incoming, unread and answered email. Based on this data, it then decides whether your current email load is light, normal or high and publishes this info to your personal Courteous.ly page (here is mine). Users can then add this page’s address to their email signatures and websites to advice people about the current state of their inboxes.
