Here are two ways on how you can create an email group of non-openers, replicate a sent email, and send it only to those people who did not open the email:
Step 1: Create an Email Group of Non-Openers
Method 1: If an email group is created using data pulled from RE NXT or if a list exists from an Excel import
Go to Members -> Engagement Studio.
Click on Add record filter, and paste the filter by selecting the list from Data Studio.
Click on Add engagement filter to create and filter out email non-openers.
Click on the + sign to create a new filter. Add a name to the filter and select the email campaign from which you want to identify non-openers.
You can apply the filter settings: Exclude who -> Opened a bulk email -> Email name -> More than 0 or Include who -> Opened a bulk email -> Email name -> Equal to 0
Once completed, the non-openers will be listed in the table.
Click on the cog icon and create a list. Using this list an email group can be created.
Method 2: If there is no existing list
Step 1: Export the recipient status data and filter out those who didn't open the email.
Step 2: Create an Excel import and then a group can be created with that data list.
Step 2: Replicate the Sent Email
Open the sent email and click on Replicate Email.
After copying it, add the email group created using Engagement Studio or the recipient status data.
