Follow these steps to create a follow-up campaign:

1. Log in to the CRM. 
2. Click main Menu.

4. Click + Add Campaign. The Add Campaigns page opens.
5. Select Follow-up Campaign.
6. Choose the parent campaign (the original email you sent).
7. Set the criteria to Not Opened.
8. Select the email template you want to use and configure the rest of the settings.
9. Set the Send Time for when you want the follow-up email to go out.
