Responsys Strengthens Leadership Position with Acquisition of INBOX Marketing February 3 2006 Award-Winning Firm Brings Full Complement of Strategic and Tactical Services Expertise to Industry-Leading Email Marketing Solutions Provider February 3, 2006 – Responsys, a premier provider of on-demand email and lifecycle marketing solutions, today announced the acquisition of INBOX Marketing Inc., an award-winning professional services firm specializing in the strategic optimization of email marketing programs. With this acquisition, Responsys expands the breadth and depth of its professional and account services capabilities to support a rapidly expanding client base of sophisticated, ROI-focused marketers. For the past five years, INBOX Marketing has sustained a winning track record helping marketers scientifically optimize their customer acquisition, conversion, and retention programs using a unique methodology and a proven set of best practices for strategy, creative, testing, and email program management -- with guaranteed ROI. Based in San Francisco, INBOX Marketing brings to Responsys a team of experienced marketing strategists, interactive designers, campaign developers, and executive management, all of whom will be focused on supporting and expanding Responsys' professional services business. "INBOX offers an unmatched ability to diagnose, design, and deliver integrated programs that help companies measurably optimize the customer experience across the lifecycle while maximizing every marketing dollar," said Dan Springer, CEO of Responsys. "Building on our shared vision of Individualized Lifecycle Marketing, the INBOX acquisition brings to Responsys greater focus on ensuring customer ROI and an expanded set of capabilities for leveraging the Responsys Interact platform to the fullest. The superior strength of our combined solution further solidifies our leadership position in the email marketing industry." Responsys was recently cited as a leader in the December 2005 Forrester Wave: Email Marketing Service Providers, Q4 2005, garnering top scores for its customer retention, technology platform, and functionality. This followed on the heels of the company's number one ranking by JupiterResearch in its October 2005 Email Marketing Buyer's Guide. The acquisition of INBOX Marketing strengthens Responsys' position as the largest private and profitable email service provider and builds on its growing recognition as the solution provider of choice for sophisticated email marketers. "As a full-service firm to leading brands, we have worked with the top email service providers and have seen many struggle to keep pace with the increasingly sophisticated needs of marketers, from both a technical and strategic standpoint," commented former INBOX Marketing President Jerome McLaughlin, now Vice President of Professional Services for Responsys. "The union of our two companies combines the best of both worlds, bringing together innovative marketing technology and world-class strategic marketing services." As part of the transaction Responsys will maintain the San Francisco office of INBOX Marketing and retain all INBOX employees. The INBOX Marketing executive team will assume leadership roles in the professional services organization at Responsys. Jerome McLaughlin will become Vice President of Professional Services and Barry Stamos will assume the role of Senior Director of Strategy for Responsys.
