Google launched a complementary feature in Gmail Labs called Smart Labels, which helps users classify and organize email, according to Gmail Official Blog.

Once to turn it on from the Labs tab in Settings, Smart Labels automatically categorizes incoming Bulk, Notification and Forum messages, and labels them as such. “Bulk” mail includes any kind of mass mailing (such as newsletters and promotional email) and gets filtered out of inbox by default, “Notifications” are messages sent to user directly, and email from group mailing lists gets labeled as “Forums.”

Labs in Gmail are a great testing ground for experimental features, and we hope Smart Labels help users more effortlessly get through their inbox, Gmail Official Blog says.
