I appreciate your help - there isn't a ton of additional detail to provide - I've looked in depth into this looking for clues and haven't found any reason within any of the flows for the second send.
It isn't even on the Calendar as having been sent again on the 31st, it just was. Hence the confusion. I didn't turn off any flow, and there are no wait steps.
I'm not quite sure what you mean by "workflow" - but here is the program, I hope this is what you mean.
Thanks again.





How do you know that it was also sent on July 31? Can you share a sample activity log record that shows that someone received the email on the 21st and 31st as a result of the same smart campaign?
