2013 was an extraordinary year for the Litmus team—we processed more than 3 million tests and over 8 billion opens. But that’s just the tip of the iceberg! We also added thousands of users, replied to tons of tickets, and nearly doubled in size. The infographic below features highlights from app usage and engagement statistics, customer support and marketing metrics, as well as the growth of the team. We believe in a culture of openness, and that extends to sharing stats about our performance, too.
