Marketing Open Data Project

What is Marketing Open Data?

Marketing Open Data is a collection of over two dozen (and growing) open source data files that are free for anyone to use. It includes data sets like Free ISP Domains, Zip Codes by City, and our favorite—Suspect Contact Names (a.k.a. “The Mickey Mouse List”). All of this data is maintained by the community, so feel free to share improvements.

What Can I Do with Marketing Open Data?

This data has been collected to help marketers clean, enrich, and validate their databases. Some marketers incorporate these data sets into their house lists using Excel with the VLOOKUP function. These tables are also used in data automation/data orchestration solutions. But, you can use the data any way you like.

How Can I Contribute to the Project?
