In the age of big data and big data analytics, the way towards better utilizing transaction data lies in narrowing the lens from a period of years and days, down to seconds.

Here’s why a well-timed email can encourage a customer to spend more, convince a customer teetering on the edge to click “buy,” or convince someone to buy from you, rather than a competitor.
