Frequently Asked Questions
How is list growth rate calculated?
List Growth Rate = ((New Subscribers - Unsubscribes - Bounces) / Total List Size) x 100 per period. It measures net list growth accounting for all losses.
What is a good list growth rate?
2-5% monthly growth is healthy. Above 5% is excellent. Below 1% means your list is stagnating. Negative growth means you are losing subscribers faster than gaining them.
