This report helps interactive marketers benchmark their email marketing campaigns against 70 of their peers that Forrester reviewed, from the consumer goods, retail, travel, financial services, automotive, business-to-business (B2B), and media industries. Our results show that across industries, marketers understand basic, but not advanced, email marketing practices. Only two campaigns we reviewed passed. Forrester recommends that you identify email improvements based on priorities specific to your industry and your level of email marketing maturity. (This report updates our findings from the "The Best And Worst Of Email Marketing, 2010" with new examples.)
