same content means
- Same emails in the same Engagèlent Programs
- Same texts and images, in a new Engagement Program?
- Same sub programs called from the EP stream?
except for case #1, Marketo will by default send the content again. And for case #1, it will not send the content again, whatever you do. You need to clone the emails and re add them to the streams.
We are using programs in the nurture with the exact same programs in a new nurture.
are you adding people as members to the sub programs when they run through the smart Campaigns ?
if so, then no EP will be able to send them through these programs again.
After Er the first cast, Marketo will mark them as exhausted content, and you will be able to move them to the next stream. You should rather test all this as any miss in the whole process will drive to unexpected results.
