Question
Same smartlist across different programs -- high audience count discrepancy
Hello,
I was just wondering -- I have used the same smartlist for two different email programmes (two months apart) that's part of a newsletter cadence.
Our data has not been cleansed, but the most recent campaign shows significantly lower audience count. What could be the cause for this? Does Marketo have an algorithm that automatically removes contacts based on a certain criteria?

Appreciate your help!
