Depending on which survey you read people spend anything from 3-10 minutes per day deleting email. That amounts to about one full working week per year spent on email storage management alone. It’s clear most businesses need to find a way to reduce the email overload.
The above quote is from an article by Jatheon entitled Reduce the Email Overload: 3 Steps to Better Email Storage Management. The article deals with having policies in place for using CC, having group discussions and giving staff guidance on how to handle business updates. It is by no means comprehensive, but it hits on the key point that managing e-mail is not about technology, but making sure staff have policies and procedures in place so they can mange their own email properly.
