My company sells about 7 different products. They are available for purchase through several different channels - our Shopify store, our Amazon store, and retail in physical stores. Once a user purchases one of our products, they activate the product in our app.

We currently have 7 different post-purchase flows for each of the different products. As the 7 products are similar, the 7 post-purchase flows are extremely repetitive. 

Is 7 different post-purchase flows really the best way to set this up for the long term?

Is there a way that we can put logic into emails to show targeted content that is specific to each of the kits?

Given that the products can be purchased through many different channels, we cannot use just the Shopify events to trigger the post-purchase flows. We will need to trigger emails based on when a user activates a specific product in our app. The app will need to call the Klaviyo API to either add the user to a list, or something else. Perhaps when we make this “add to list” call with the Klaviyo API we can set a custom variable. 

Is there a standard best practice for how achieve easy to maintain post purchase flows? I do not see an example that is exactly like what we are trying to do.

Thank you!
