How can brands best use data to identify and connect to customers across their journeys? In a recent interview, Nick Dujnic, Senior Director of Marketing at LiveIntent, sat down with Liam Doyle, VP of Advertising Products for Salesforce Marketing Cloud, to discuss these and other topics related to identity-based marketing.

When asked what is the most important form of identity data, Liam replied, "There's one identifier that cuts across all of the different places where we spend our digital lives - and that's the email address."

The email address has evolved beyond simply a means of sending and receiving email to become a central component of everyone's online identity. Through integrations with Salesforce Marketing Cloud's Advertising Studio, it has become a way to reach customers when and where they are paying attention in paid media channels like Facebook, Google, and LiveIntent.

That concept of identity tied to an email address is central to LiveIntent's platform, which allows marketers to reach an audience of 135 million people with display ads in the email newsletters of 1,300 of the world's top brands and publishers. Through the partnership between Salesforce and LiveIntent, customers of Marketing Cloud can seamlessly target their existing customer segments with ads across the LiveIntent platform.
