Email is hard to search, and a lot of times, isn’t a great place to get actual work done. That’s where Evernote comes in. If you already forward a lot of emails from your Gmail account to Evernote, you’ll find Powerbot for Gmail to be a smart work tool. It lets you add tags and comments to your emails, pull in links to notes or notebooks from Evernote to any outgoing email, and do it all right inside the Gmail interface.
