For several years, Forrester has evaluated database marketing service providers in the US. However, not all of these providers operate internationally, and we receive frequent inquiries specific to the UK market. In Forrester's 77-criteria evaluation of UK database marketing service providers, we found that all eight provide a compelling offering. RAPP, Marketing Databasics, Occam, and GB Group led the pack — due in large part to a combination of advanced analytics, strategy services, and strong account management. Dataforce, Acxiom, Callcredit Marketing Solutions, and Experian Integrated Marketing are all Strong Performers: Dataforce is a worthy all-arounder; Acxiom, Callcredit, and Experian each offer strong data sourcing and a solid range of services.
