Nurture streams and duplicate content
I have set up three nurture streams in our nurture campaign. The only difference between the three streams is the audience which pulls from three smart lists. One sends on S/T/Th, one on W only and one on Th only and they share content. For example, on 10/7 and 10/8 all groups would receive message number 74.
I noticed that even though the content was approved and activated in the W only stream, it did not send out the message yesterday. It did send to the S/T/Th group today but did not send to the Th only group.
Each of the streams has their program participants. I understand that one stream cannot send duplicate content but I assumed that a single message could be sent to different streams. I've gone over the set up with a fine-toothed comb and don't see anything glaringly wrong so what should I check next?
