Robert Scoble, who has written about his struggle with email many times, has published an article at FastCompany recommending six tools to help get on top of email. ClearContext is mentioned alongside ActiveWords, Xobni and Gist:
“If I were going to recommend only one tool, ClearContext … offers the most immediate productivity gains. The Outlook add-on looks at who you're replying to and how often, then automatically prioritizes the messages. It color-codes the most pressing ones, graying out mass emails. This is a small thing, but it minimizes a torrent to a manageable few. ClearContext removes that dread we feel when we open our inbox.”
Thanks, Robert! Here’s Robert’s interview with Deva last year (Get a handle on your email with ClearContext):
