I need to a send proof of a complex dynamic content email (20 variations) to a stakeholder on a monthly basis. I stumbled across a salesforce video that says I can create a data extension with black hole email addresses and use that to do an advanced guided send just for testing that will send all 20 versions of the email to one email address.
In my guided send I don't see a testing option. Is this video out of date or is it still relevant and my account just doesn't have this feature turned on? https://www.salesforce.com/video/297717/
