I'm sending to multiple Data Extensions and I need content to dynamically populate based on whether or not an e-mail address is in a given Data Extension.
I created a paste HTML tempalte in Content Builder, inserted a Dynamic Content Block but when I go to set up the rules there isn't really one that works for what I'm trying to do. In a perfect world the rule would check to see if an e-mail address is present in a specific DE, if so, display the dynamic content. If not, display default content.
I found this which shows it's possible with AMPScript. However I'm looking to see if it's posible using Dynamic Content in Content Builder.
