Is there a way to see how many people are set to receive the next blast email of an engagement stream?
And not just by running a smart list of who all received the previous email, but in case of adding people manually to the middle of a stream, etc.
That would be a really helpful feature!
There's currently no way outside of estimating audience size based on 'Last Cast' amount in the stream view or running a smart list.
If it's that critical to operations, I'd wager you'd want to run a smart list to check anyways. I attached a smart list I used to get a pretty accurate count of tomorrow's sends for a stream based on the previous cast.
