Did you know you can unsend an email via Gmail? I'm totally geeked about this as I send most of my emails via my phone and quite often I am on the go. I set this up in my gmail settings and changed the time setting to 30 seconds. So helpful!
Thank you to Jim Losier for sharing!
CLICK THE SETTINGS WHEEL UNDER YOUR ACCOUNT ICON
UNDER YOUR SETTINGS CLICK LABS
UNDER THE LABS SETTING SCROLL DOWN AND FIND UNDO SEND: CLICK ENABLE
AT THE BOTTOM CHOOSE SAVE SETTINGS
And VOILA.. you now have 30 seconds to unsend and fix your problems before you send again!!
LOVE THIS TIP.
