Overwrite info during an import

[Anonymous]

If I import a lead list with the "Industry" column (for example) blank and the lead is already in my system with that information, will it delete the industry info in after the import?

It depends on what settings you have for that field in Marketo. Check out this article: https://community.marketo.com/MarketoArticle?id=kA050000000KzVrCAK

Just to clarify: Null/Empty/Blank will never over-write a field that has a value in it, regardless of the field settings.

I was hoping for that answer... thanks!
