Xobni, the company that helps you manage the contacts in Outlook by telling you who is important and who’s not, has launched a new feature that brings in third-party details beyond social networks to services like Evernote and Dropbox.

The self described “relationship management service” has previously only offered ways for users to analyse their email data to see things like who they email the most, or contact details of those people.

Now however, the company has launched a new platform it’s calling the Gadget Platform and Store, which lets users access further information outside of the inbox.

That means, for example, seeing which files you are sharing with those contacts via Dropbox or perhaps notes you’ve worked on together in Evernote, Eric Grafstrom, the company’s head of operations, explains to Pocket-lint when demoing the new product.

The new feature works using Open Social allowing it to run in a side panel in Microsoft’s Outlook for the PC, with details dynamically changing as you select different emails.

There will be around 20 apps to start with, with the plan to include more and more over the next couple of months, Grafstrom tells us.

Apps will either be free or come with a $9.99 per year and 30-day free trial set by the developer, although it’s clear from our demo that the majority will be free.

“For years, Xobni has given users access to Facebook, LinkedIn and Twitter information for their contacts right in their inbox. Thanks to our partners and open standards, we’re now able to offer many more services that help users save time and effort,” said Jeff Bonforte, Xobni CEO. “This platform also gives developers an easy way to reach hundreds of millions of Outlook users, while using the same code for Gmail.”

Apps for day one include Dropbox, Evernote, GoldMail, Google Translate, Atlassian JIRA, WebEx, Huddle, Microsoft SharePoint, Salesforce Chatter, Yammer, Facebook, Flickr, Hoover’s, Klout, LinkedIn, Twitter, Xing, YouTube, Yelp, and Salesforce CRM.

Currently the new offering is only going to be available for Microsoft Outlook users, however Grafstrom hinted that support for other platforms was coming soon thanks to the nature of the way the side panel is created; leading us to believe that a Gmail offering will be on the cards very shortly.
