Since a few days ago I had about 900 subscribers, then I went on the subscribers page and I noticed more thank 1K subscribers not confermed; on “massive changes” I then re-sent the confirmation emails to all of them and I got 50 more subscribers.
Problem is these new subscribers, even if on the confirmed subscribers list, don’t get counted when sending new newsletters. It’s like the plugin doesn’t get them because they’re confirming with the “massive changes” email.
When subscribers are confirmed it does not matter how or when they confirmed. If you prepare a newsletter and the counter show only 900 while you expect 950, just be sure there is no filter set (sex, preferences and so on).
