What is the best way to find fields with no data in them, both Marketo only and SFDC fields. I want to try to decommission some fields that are not used and would prefer a full delete rather than hiding.
Frank, we utilized Field Trip app exchange tool in SFDC to analyze the fields and cleanup. Probably that will be helpful.
Don't forget to first bring in each field in the field management area of admin to double check it is not being actively used in any smart lists, reports, smart campaigns, etc.
