    FAQ: email list growth

    How do you calculate email list growth?

    Email list growth is current subscribers plus new subscribers minus unsubscribes, bounces, and other churn over a time period.

    Why does list growth matter for funnels?

    A funnel needs enough qualified subscribers entering it. List growth without engagement or conversion quality can still hurt performance.
