ABOUT A DECADE ago, spam brought email to near-ruin. The contest to save your inbox was on, with two of the world’s biggest tech companies vying for the title of top spam-killer. By February 2012, Microsoft boasted that its spam filters were removing all but 3 percent of the junk messages from Hotmail, the company’s online email service at the time. Google responded by claiming that its service, Gmail, removed all but about one percent of spam messages, adding that its false positives rate—legitimate mail misidentified as spam—was also about one percent.
