A very useful feature for measuring subscriber engagement, it is not currently supported by Themes and so requires deviating from the OOTB code in order to implement.
Hi Elinor, thank you for the idea. I will add this as "future consideration" since it is an idea worth exploring; we could potentially offer an out-of-the-box implementation for Arc Subscriptions using our default output type, and we'd look at ways to make it more flexible for other providers. I'll update if/when we pick this up!
