The most important list you should be looking at is your engaged segment. NOT your overall list size. The overall list size doesn't tell you anything really. If you are sending to only engaged segments, as you should be, then anyone not on the engaged segment is not worth thinking about. Check your engaged segment list growth and make sure it is growing! A hack you can do to reegnage dormant people is to send a campaign once a month to your entire list. This should reengage some people.
