Rapportive shows you everything about your contacts right inside your inbox.You can immediately see what people look like, where they’re based, and what they do. You can establish rapport by mentioning shared interests. You can grow your network by connecting on LinkedIn, Twitter, Facebook and more. And you can record thoughts for later by leaving notes.

Now the startup is adding yet another layer of social utility to the inbox with its new Twitter integration. The Twitter widget lets you follow your email contacts, send them replies, and retweet or quote them from inside email messages. You can also take a quick glance at whether your email contacts are following you on Twitter.

Now the add-on will help you interact with your contacts on Twitter without ever needing to leave your inbox.
