I need to do a mass update to all of the email templates in Salesforce Marketing Cloud. From what I've researched, there are no built in app tools do allow this.
I know a popular tool for exporting/importing to Salesforce (not sure which segment it applies to) is Excel Connector, but not sure if that would somehow work for Marketing Cloud.
Would the Excel Connector have access to all different segments of Salesforce including the Marketing Cloud?
What are other ways one could bulk update email templates in Salesforce Marketing Cloud?
