Hello @pqo,

Thanks for sharing this with the Community.

That is a great idea! Although Klaviyo is not yet able to tell you exactly what percentage of new subscribers have converted to customers within X amount of days, you can generate a report that shows both subscribers and placed orders within X amount of days using the report builder. Something like the following:

Additionally, you can run engagement reports on each of your lists to see what the average order value and overall engagement of the list/segment is.

Hope that is helpful!
