Kenton Varda gets dozens of messages a day from Spanish-speakers around the world, all thanks to a Gmail address he registered 16 years ago.
TWO WEEKS AGO, longtime software engineer Kenton Varda got an email that wasn't meant for him. It was from AT&T Mexico to a customer named Jorge, whose most recent phone bill was attached. You've probably gotten an email intended for someone else at least once. But then Varda got another AT&T Mexico bill for Gloria. And then a third for Humberto, who is overdue on paying more than 6,200 pesos, about $275.
