Knowledge base / Lists and subscribers
Subscriber statuses
Pending, confirmed, or unsubscribed. Unsubscribed keeps the row; erase removes it.
Pending — joined, not confirmed. No article or broadcast mail.
Confirmed (active) — used the confirm link. Receives RSS email and broadcasts for that list.
Unsubscribed — asked to stop mail. The address stays on the list so you can see they left. They are not mailed.
To remove the address and related events, erase rather than unsubscribe.
