LinkedIn adds career highlights to emails The Mountain View, California headquarters of careers-based social-networking internet site LinkedIn. NETWORKING site LinkedIn is offering a new mobile feature that will highlight information about people's careers in emails being read on iPhones. The tool, called LinkedIn Intro, pulls details from the company's online professional network so the recipient of an email can learn more about the sender. The information will be limited to what the email senders already allow anyone to be seen on their LinkedIn profiles unless they already have granted the recipient broader access through a connection on the service. The feature released overnight works with Gmail, Yahoo Mail, AOL Mail and Apple's iCloud when any of them are plugged into the iPhone's built-in email app. LinkedIn plans to update the feature so it also works with Microsoft's Outlook.com and Exchange email.
