DiGuido came to Alliance Data Systems' Epsilon Interactive division when the company purchased Bigfoot Interactive--one of the largest independent e-mail services firms--for $120 million last year; DiGuido had previously served as CEO of Bigfoot Interactive. Earlier this year, in a major industry consolidation, Alliance acquired DoubleClick's e-mail business for $90 million.
This week, Epsilon also reorganized into four separate groups: Strategic Database Services, Epsilon Interactive Services, Agency and Direct Services and CPC Associates.
