Strategies for Cold Emailing Workshop Sign-Ups and Funnels

Guys, I just got a client for my cold email agency with the following offer - Offer: $7 for a 5 day workshop on how to run Amazon ads At the backend of this 5 day workshop they sell a 4 figure mastermind. Curious to know your thoughts because cold email is usually for high ticket services & usually the goal is meetings. My goal is to just get sign ups for the workshop. Anyone here who has experience with these kinds of offers? I'm wondering what would the funnel be?
