I have been using Modern Postcard for over 6 years and have never been disappointed. The quality is always top notch and the service has been overly helpful. I have purchased lists from a number of different printers over the years and Modern Postcard has been the most accurate and up to date. The mailing lists were easy to customize and have given us a great return. Working in non-profit it is essential to have the best coverage with every mailing, Modern Postcard has helped us achieve this. You are in good hands and won’t be disappointed.
