This report lays out Forrester's vision of email marketing for interactive marketers: Integrate email into a multichannel conversation that includes a number of non-email communication vehicles. Why? Because direct messaging options have proliferated to include myriad digital channels such as email, social media, SMS, and mobile app push notifications. To meet user expectations across all of these and create business value, marketers must shift to what Forrester calls customer-focused integrated messaging. This report is an update to "The New Messaging Mandate," originally published on January 9, 2012.
