List growth is a compounding flywheel
A 1.5% visitor-to-signup conversion looks small until you compound it monthly. The math reveals which lever to pull: more traffic, higher signup rate, or lower unsubscribe rate. The unsub rate is usually the cheapest to fix and the most overlooked.
Frequently Asked Questions
What signup rate is healthy?
1-2% is normal. 2-4% is excellent. Above 4% usually requires high-value lead magnets or strong popup strategies.
