Our customer marketing team is preparing a program to send out of Gainsight. Part of the recipients of the program is able to built built from Gainsights query builder tool. The other part is a CSV file of contacts that has a lot of data (but not any Gainsight data like company IDs or relationship IDs).
What is the best way to get this data into Gainsight so that it can be linked up with Gainsight ID fields for reporting capabilities? Create a new custom object and data load the file into it and then do a query builder merge with company data?
