Sometimes you can tell more about the quality of a business by how they resolve issues. We bought a list from Ben’s Company National Data and it was not exactly what we needed and not only did Ben respond quickly, but he also went the extra mile to resolve the issue to our 100% satisfaction. It’s rare these days to find a business that will put your satisfaction as their absolute priority. Ben’s attention to our needs make him and National Data a valuable business partner.

The list I purchased was sub standard. They have a disclaimer on their contract that is absolutely correct. It will not work with Constant Contact. Im not happy at all and seems there's no way to get comped for bad addresses.

I usually don’t post a review unless I am blown away by the product and service (or a good slice of pizza). National Data Group met and exceeded my expectations. Customer Service, Quality Product, Exceptional Follow up……Enough Said…..5 Stars
