Episode 58 Building an Email Health Calculator with Michael Einstein part 2

Ever longed for a tool that could give you feedback on the health of your email inbox? Listen in as I take on the challenge of creating one from scratch. Here in the second part of LiveLab 02, I continue working with Dr. Michael Einstein by delving into the formulae that would be at the heart of a sound email health calculator. It's no easy conversation to follow - you will probably need a paper and pencil. Months before I called Michael, I devised the following formula in my very first attempt. Score = the sum of: 1. 5.0 max(0, [2 x (total messages-unread messages-tagged messages) [ 2. 0.5 x (total messages - unread messages - incomplete tasks recalled) 3. 5.0 x (unread messages - incoming email per day)]/10) 4. # minutes spent This is where our discussion started. It moved quickly and resulted in this formula which we produced in the first part of this episode. Score = the sum of:  1. (total messages-unread messages-tagged messages)  [more importance]  "BlindSpot measure" 2. # read messages * (age in days -1) [more importance]   "Morgue Measure" 3. # unread messages/ # incoming email per day [more importance]  "Backlog Measure" 4.  # threaded messages / # total messages  [moderate importance] 5.  # raw threaded messages [high importance] 6. # subscription email older than a day / # total messages older than a day  [low importance] We took a break for about a month, then reconvened to record the second part of this episode. During the discussion, we agreed on the following elements. Score = the sum of:  1. (total messages-unread messages-tagged messages)  [more important] 2a. # read non-subscribed messages * (age in days per message -1) [more important] 2b. # read subscription messages * (age in days per message -1) [more important] 3. # incoming email per day / ((#unread subs--sqrd> + #unread nonsubsc) [more important] 4.  <deleted> 5.  # raw threaded messages - for non-subscribes using geometric growth [high importance] 6. # subscription email older than a day / # total messages older than a day  [lower importance] Our next and final conversation didn't take place until 10 months later.
