New opportunity AFTER receiving an email
I'm trying to pull a list of people who received one of our emails and then created a new opportunity in the past month.
I have this smart list created

The problem I'm running into with this Smart List is that it also includes people who had a new opportunity created in the past month and THEN received an email (which is possible the way our campaigns work).
Is there a filter or logic I can add so that it only gives me people who were sent an email and then inserted a new opportunity?
Thanks
