Import a list of contacts from a file or spreadsheet

[Sue06073]

Is there a way to supplement contact information without changing list selection?  I am trying to add address information, plus data into new custom fields.  I do not want to change List memberships.  My Contacts are organized within a master General interest list, and sub-sets in other lists.   When I import a test file, it requires selection of a List, which wiped out previous additional list settings.

Hello @Sue06073 ,

When you upload a file of contacts, you can reupload contacts that are already in your system, without having to make a drastic change to your list selections. I'd advise creating a brand new list on the list selection step, then you can delete only the list after they've been uploaded with their new address info.
