I very new to Marketo and have no formal training. I have tried 2 ways and neither seems to be correct.
I built a smart list: Filters= Random Sample 2%, Campaign Name is (my campaign name), Email address is not empty, DNC is False and Lead Status is Open. This seems to be the list I need but I can't pull two different random samples?
I tried to use the Email Address is filter 25 times but it says it will not affect any leads?
