I'm sending a series of 3 emails, and need to add anyone who opened at least 2 of these 3 to a SFDC campaign.
I've entered the campaign flow as "opens email 1" AND "opens email 2" as the trigger, but just found out that Marketo didn't understand that I meant 1 + 2, instead of either one (only email 1 went out and I already have people on the 1+2 campaign).
Can someone please help me figure out how I can set up the filters so I can only see people who opened a combination of 2 emails?
Thanks!
