Lets say I have a customer that provides me a list of 100,000 subscribers. The customer also supplies a list of opt-out totaling 15000. How does Mailwizz handle both lists? Can both lists be imported then Mailwizz reads from the opt-out list and then doesn't send to that subscriber? How does that work? Thanks! ![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
