Four51 Inc. and Pageflex have expanded their strategic partnership to deliver a scalable Internet-based solution to manage targeted direct mail campaigns, variable data print solutions, and Web-to-print and on-demand print programs. Since 2004, Four51 has provided development and hosting of Web interfaces to customize direct mail campaigns, document output using Pageflex Mpower, and distribution of output files to select print facilities. It will now provide a migration path for companies that decide to move their production servers in-house and host their own Pageflex Mpower Web-to-print systems. In addition to offering commerce-on-demand services, Four51 also will offer customers training in how to design for variable data campaigns using Pageflex Persona Cross Media Suite. This desktop application incorporates variable data and cross-media functionality. It will enable internal marketing departments and agencies to develop direct mail campaigns that are then executed through the Four51 system.
