Rapportive is a free app (recently acquired by LinkedIn) that shows you everything about your contacts right inside your inbox. Rapportive helps you build rapport quickly (hence the name) and is "relationship management built into your email." It functions as a Gmail add on.

I've found Rapportive helpful in getting a clearer picture of the person I'm emailing, especially if the connection is new. After entering the email address, a sidebar appears with an instant snapshot of who you are communicating with,  helping to bring your contacts to life.The Rapportive bar shows a picture, any other social media details accessible for the contact, and even a space for you make a private note. Handy, right?

Recruiter Uses:Keeping track of candidates, clients, peers; putting a face to the name; ability to get connected via other social media platforms from one strategic location (your own inbox); keeping notes on facts pertinent to the contact (birthday, spouse's name, where you met, etc.)

Caveat:Only works with Gmail currently

Tech Tools Review Rating: Why not? Easy, free and minimally intrusive to the Gmail screen. Check it out at http://rapportive.com/.
