For all the Microsoft Outlook users out there: the solution to all your inbox frustrations is here! Xobni announced today the availability of an add-on for Outlook that organizes emails by relationships, to save users time and help them find exactly what they’re looking for in what sometimes can be a messy inbox.

After two years of development and seven months of invite-only beta testing since September 2007, Xobni is now available for download here. The add-on will be displayed as a sidebar in Outlook and is said to organize emails the same way our brain normally would, by analyzing the way we interact with contacts and the files that have been exchanged, the company unveiled.

Matt Brezina, co-founder of Xobni, said: “Xobni analyzes mountains of data and shows you what matters – your relationships, your communication habits, context around messages – information trapped in email that is often lost or forgotten.”

Xobni developers have been working hard on their latest creation by relying on users’ feedback over the past months (over 50,000 users have participated in the beta testing). “We will continue to work hard to improve Xobni experience,” Matt Brezina said in a blog. “Xobni has done a lot to improve our users’ email lives, but email and personal information still have a long way to go.”

Although widely available, Xobni will remain beta to better respond to user feedback, its developers unveiled, saying it’s better to wait: “a true beta is an idea rarely visited in what’s become a development culture obsessed with launching as quickly as possible, sometimes without consideration of the product’s future.”

Xnobi will not stop at Microsoft Outlook, as future plans include web mail services, such as Gmail, Hotmail or Yahoo Mail. In a world where communication over the Internet has become an everyday habbit (necessity even), Xnobi comes to respond to the challenge and make the e-mail faster, easier, stress-free, by improving user experience.
