Welcome to MEDbase200
We are the sole owner of the marketing lists you are about to discover. The MedBASE200® Masterfile has emerged as the leader in the field of niche medical and specialty mailing lists. This vast collection of list assets is owned and managed by our firm, Integrated Business Services, Inc., which has earned a reputation for completeness and refinement unequaled by other list providers. Established in 1982, our initial focus was the medical imaging marketplace, with particular focus on radiology. Thirty (30) years of healthcare marketing segmentation experience, and our expertise with Survey/Response-based medical data files has enabled our team to isolate growth markets and develop the most complete and most selectable mailing list files available today, offering our marketing clients the combined options of … unmatched list size, selectability, savings and safety.
Our privacy policy is among the most rigorous in the business. The mailing lists we develop are HIPAA-compliant, and are updated frequently and regularly using the most sophisticated methods available. Before shipment, all files undergo yet another NCOA/CASS/DPV-certification and deceased suppression, so that updated postal documents can be provided as needed.
Take a moment to peruse through our new website, in celebration of our thirty (30) year anniversary in this ever changing industry. More than ever, we are ready to become your marketing partner, working together with you to produce direct mail and online marketing profits.
