Subscriber Import Policy Change

A quick heads up: The subscriber import process has changed. As well as suppressing individuals who have been deleted (manually or via the bounced mail handler) or previously unsubscribed from the list you're importing to, FeedBlitz now also suppresses subscribers who have unsubscribed from any list you manage, regardless of whether it's the list you're importing into or not.

So, say you have two lists, A and B. John unsubscribes from A. You can now no longer add John via import to list B.
