David Cass writes in CMI’s Professional Manager (Spring 2016) of a company he worked in where they seemed to tackle Inbox overflow head on.  Managers devoted time hunting down (David’s words) the offenders of unnecessary emails and asked them to justify why they had included that manager in their distribution list.

This might seem like a burden worse than the email nuisance itself – but David is certain that the impact the campaign had in reducing pointless email traffic far outweighed the effort and the time costs that it took to address the issue.

I’m not sure I’d ever like to call it hunting down (I fear it being done badly by the wrong people), but I wonder, in principle, could this work in your organisation?
