marketo<>salesforce campaign member sync
Hi!
I'm very new to Marketo and I'm trying to understand the sync between Marketo/Salesforce. My question is that if I have a program in Marketo with members based on a smartlist that feeds from contacts in Salesforce matching a certain criteria. I know that Marketo will create a campaign in salesforce relevant to that program (not sure if its always automatic or needs to be manual) and add campaign members mirroring the smartlist members in Marketo. What happens when a contact changes some of their attributes and are no longer matching the smartlist criteria, will Marketo delete that contact record from the campaign members of that specific campaign?
excuse my ignorance here, any help is appreciated!
Thank you!
