Sometimes, you might want to move those prospects that did not open your emails into a duplicate sequence to give them another chance. Smart filters can help you with this:

 1. On the Sequences page, create a duplicate sequence.
 2. Open the original sequence and navigate to the People tab. 

  3. Create a smart filter with the following properties: Status: Opened and False.

 4. Apply the filter to sort the prospects.
 5. Select these prospects and move them to a duplicate sequence.
