I'm looking to add a conditional split to one of my flows.
Essentially, we are sending 4 emails over 1 month. After 30 days they hit the conditional split. I'm looking to have anyone who has opened one of those 4 emails continue on the flow and anyone who has NOT opened one of those 4 emails to be split onto a separate branch.
However, when I go to make the trigger, it is just a generic "Opened Email at least once in the last 30 days".
There is a filter option, but when I select it and go to choose my property it says there are no items on this list.
I found this article on segments where it's mentioned that you can build segments off who opened a specific email. However, I don't know how to do this.
