BlinkMail is an email app with a laser-like focus on speed. It is completely driven by keyboard, which lets you get through dozens of incoming emails in seconds. Notable points:
- Uses keyboard arrows to quickly process incoming emails
- Supports multiple Gmail or generic IMAP accounts
- Integrates with Evernote, Dropbox, OmniFocus and Things (coming very soon)
- Stays in the menubar, doesn't get lost in the Dock
- Currently in beta and is completely free
