I'm trying to set up a campaign where I send one email, wait 3 days and if that email remains unopened send another email, wait 5 days and if the first and second email remain unopen send third email.
I have tested and the second email is delivered but the third email does not trigger.
I have tried many variations to the flow to get it to trigger but have not been able to get it to send.
I can't identify where I'm going wrong.
Any advice would be appreciated.
