Correct contingent upon when they register you have a smart campaign moving them to the registered status for that program.
+1 on Jessica.
If you do not have the smart campaign in place to set the program member status, use another smart list with a "filled out form" filter.
And also, get some training, it will save a lot of your time and prevent a lot of mistakes start with the Marketo university.
Hi Jessica & Gregoire - Thanks for your input. I actually have SM in placed to store them as "Registered" once they filled up the form. For some reason, when I use the Member of Program is True and constraint Status<>Registered is not working on 2nd invite. There's no people/leads on the view. Tried the filter "Not program status was changed" and that works for me.
