Having pioneered competitive email intelligence monitoring, eDataSource has built a panel of consumers that mirrors the U.S. online population enabling us to accurately gauge inbox placement, open and delete rates; overlap with your audiences; mailing volumes, segments and cadence — as well as search on any keyword to understand winning subject lines, promotions, creative and affiliate partner strategies — across vertical industries and population segments.

This powerful technology is backed by a seasoned Strategy & Analytics team that can deliver fully customized reporting to help you harness all the insight.

Our History

As the first email intelligence company, eDataSource was founded in 2003 by Cullin Wible and Bill McCloskey ( and the Email Innovations Summit), instrumental thought leaders in the email marketing industry. At that time, eDataSource began changing how marketers, publishers and service providers compete in the inbox.

In 2011, the acquisition of Boxbe, Inc. was a significant milestone in the company’s growth. For the first time, marketers could use eDataSource solutions to understand email marketing from the point of view of a consumer panel instead of seed data. With this, the ability to display actual inbox placement statistics as well as competitive email insight in real time — an absolutely unique value proposition for the market — has become a staple in measuring email deliverability for marketers at companies of all sizes.

Our platform is used by leading brands, email service providers and market research firms across the globe. Our client roster represents every part of the interactive marketing industry, from Fortune 500 companies to digital agencies to email service providers and affiliate managers. Some recognized names include Darden, Footlocker, Kohl’s, Mintel, Movable Ink, Nielsen, Oracle, Publisher’s Clearing House, Salesforce, Staples, Vera Bradley, Zeta Interactive, and many more.
