I've been reading a lot of posts about the purpose of the Marketing Suspended field, but still have a specific question. If a person becomes Marketing Suspended, is there a time constraint by default? Will Marketo automatically un-suspend them after a certain amount of time? Or, do we have to manually un-suspend them? I've heard different things in the past, e.g. its automated and Marketo will take them out at 30 days, 90 days, etc., but don't have a concrete answer. Thank you!
