A large mailbox affects the performance of your email
Empty your Deleted Folder
This one is easy; you wanted to get rid of it? Well do get rid of it! Right click the Deleted Items folder and choose “Empty Deleted Items folder”.
Keep your inbox empty
There’s something strangely satisfying about a clean inbox. It increases productivity because you can zip right through your inbox in a few minutes without having to sort through old ones. And it reduces mental clutter. There’s nothing like a stuffed-to-overflowing inbox that weighs you down.
Touch it once
This is a mindset you have to work hard to get into, but once it becomes habit, you’ll love it. When you open a message, review it and then do something with it. Don’t let it sit there! Emails that sit there only have to be weeded through again later, costing you more valuable time and energy.
Don’t be afraid to delete
After reading Email always take action on that Email . Don’t save it for later or move it into a folder to be forgot about. If you’re unable to take action on the Email , delegate it to someone else, or postpone it for later that day delete it. Every Email doesn’t need a response and there is no reason to save an Email that’s going to be deleted months later.
Declare email bankruptcy
If your inbox is completely out of control, declare email bankruptcy. Bite the bullet and delete it all (or, if you’re not quite ready to take such a definite step, archive it all). Start over, start fresh. If it’s been sitting there for months, the person who’s waiting for your reply is most likely over it. And be realistic, are you really going to get to all those messages? Decide which of the most recent ones you want to keep, select the rest and delete or archive. No one will die, I promise. And think of how free you’ll feel!
