Question
All Casts vs. Last Cast
The engagement program I'm referencing is set on a 14 day drip. Each recipient that receives an email is automatically sent the next email in the stream on the next cast. Can anyone explain (clearly) to me why I see such a variance in all casts to last cast? It is my understanding now that the drop either means people unsubscribed or the data was incorrect (i,e bad email addresses).
