Classic Rebound stuff. \n\nThere is also a Node \"Some Options...\" which can be adjusted to quickly change the direction this Campaign should go.\n\nAdditionally we use n8n to generate the HTML Mails by two different Templates. One with simple text and another for that Coupon handling.\n\n\nEnjoy the Workflow! ❤️ \nhttps://let-the-work-flow.com\n"
