hello. there's one thing that could use more transparency: the List Optimization feature shows a "Non-openers (months)" metric, but there's no documentation explaining whether this accounts for how long a subscriber has actually been on the list. If a subscriber joined 3 days ago, are they counted the same as someone who's been ignoring emails for 6+ months? Would love some clarity whether the platform just sums up all inactive months regardless of how long the subscriber has been on the list. thanks!
