Have you ever sent an email that you wished you could have back a fraction of a second later? It is so easy to type something in anger, accidently include someone you wish you hadn’t, or to say something in a less than polite way. Or maybe you just hit “send” before you finished typing? While you can’t get back any of those emails from the past, there are ways to set up your email so you can undo them moving forward. Gmail now has an “Undo Send” feature and there are browser plug-ins that work the same way. You’ll only have up to 30 seconds to change your mind but that’s better than nothing!
