I have a SFDC Campaign (let's call it CAMPAIGN_A) that has exactly 1,000 members.
In Marketo, I created a smart list (in the Lead Database section) with exactly one filter:
Lead: In CAMPAIGN_A
It returns 808 leads.
How could that be possible? There are no other filters / anything associated with the smart list. I've attached a screenshot here.
nevermind, just a slow sync. sorry.
