Finding Contacts that Have Opened One Specific Email
I've imported a list into Marketo that was used for one particular "terms and conditions" type email. A large portion of this list are non-marketable contacts. However, there are some contacts that are on this list that are involved in other campaigns I'm running. I can't figure out how to run a smart list to find the following:
Member of List: List is A
Has only been sent Terms and Conditions Email
The filters I'm running seem to be showing me who's on the list and was sent the email. But that isn't meaning they couldn't have received others. Hope this is making sense and that there's an expert out there!
