e-Dialog Ranks Highest Overall Among Service-Oriented E-mail Marketing Providers in Independent Survey

Prominent Analyst Cites Company's Business Value, Account Servicing, Strategic and Creative Input, Campaign Management and Analysis Applications as Keys to Success LEXINGTON, Mass., October 18, 2005 -- JupiterResearch, in its recently released report, " E-mail Marketing Buyer’s Guide, 2005 " (October 2005) ranked e-Dialog the highest overall among service-oriented e-mail marketing providers. In addition to scoring first in business value and market suitability, the company is recognized for its account servicing, strategic and creative input, attention to mailing detail, and campaign management and analysis applications.

JupiterResearch’s report included an in-depth evaluation of 30 e-mail marketing service providers (ESPs). The assessment incorporated detailed interviews with clients of each vendor, a demo scenario, and evaluation criteria such as professional services, application features, functionality and usability, and technology integration.

"Stand-alone ESPs not only account for more revenue and e-mail volume than mixed-media ESPs do, but also outperform the overall market regarding average annual growth. Overall, ESPs covered in this report grew by 30 percent from June 2004 to June 2005. For the same period by category, mixed-media ESPs grew by 25 percent, and stand-alone ESPs grew by 33 percent," JupiterResearch reported. "Although JupiterResearch expects consolidation to continue, buyers should be skeptical of the all-in-one approach. No on-demand or service-based analogue in the technology sector illustrates consolidation of related services radically delivers more value."

In the report, JupiterResearch made the following comments about e-Dialog and its e-mail marketing applications:

"This independent endorsement from such a prominent industry analyst firm underscores our commitment to helping clients meet and exceed their e-marketing goals," said John Rizzi, chief executive officer for e-Dialog. "Everyday the entire e-Dialog team works to bring our services, technologies and tools to the next level so that our clients can reap the economic benefits of e-Dialog’s outsourced solutions. With all the industry consolidation underway, it is gratifying to see that focused, stand-alone vendors are outpacing the industry and providing the best solutions to clients. As e-Dialog stands now as the largest independent full-service provider, we will continue to set the pace for world-class marketers that want to bring their e-mail programs to the highest possible level."
