Gideon Lichfield writing in Quartz notes: You are wasting your time on email. Now more than ever. Quit! Average email reply time in 2012 went up to 2.5 Days from 2.2 days in 2011. (according to Cue.com which also notes that dogs are mentioned more often than cats in corporate email. 38% vs 32%).

The forward thinking Lichfield also observes:

On current trends, then, if email response times keep increasing by 10% a year, and assuming that an average postal delivery time in your country is two days, I estimate that by approximately 2020 it will be faster to get an answer from someone by writing a letter than by sending an email.

(his bold statement)

Be ahead of the pack; begin with #noemail today (really you should give some announcement beforehand. See suggestions throughout this blog for how to quit with grace).
