He has found two options to help you stop the time-drain that is known as email. We've all tried unsubscribing to newsletters, and avoiding getting locked in to daily updates, but still, we waste hours each day plowing through a full mailbox, just to get it down to a manageable number. And then, the next day, we start all over again. Yes, we all know its a losing battle.
John's suggestis are for inbox tools that might help:
Unroll gives you a fast way to unsubscribe to all the sites that have you as a subscriber.
SaneBox is a fee-based service, $4.95/month, that analyzes your messages before delivery, to pre-sort by priority. The low-priority items are then summaried and pavailable for you to scan na single message.
If email continues to waste your time, try these or other resources to keep you from losing productive hours each week.
