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?

I was hoping for that answer... thanks!

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

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