We would like to have all our leads repeat the entire stream once they've exhausted the content. What are the best practices to be able to do this? We have about 70 emails that we have in our prospect stream, and it takes roughly 90 days for the leads to become exhausted on all the content. How can we get it so that those leads will then restart the entire stream once they've exhausted everything? What kind of program would be best to be able to do this?
