Finding leads that were sent only 2 specific emails
So we had 2 emails that accidentally were sent to our entire database, which caused us to get blacklisted. I'm trying to see if I can identify the leads in our database that received ONLY those 2 emails and nothing else ever from Marketo. Is there a way to do this in a Smart List perhaps? We have a bunch of inactive leads that I cannot identify so I thought this may be a way of finding those to be deleted since they are not being included on any other sends.
