Frequently Asked Questions
What is a good newsletter open rate?
Industry averages: 15-25% for large lists, 35-50% for engaged lists, 50%+ for small/premium lists. Aim for 40%+ for monetization. Below 20% suggests list hygiene or deliverability issues.
How do I calculate subscriber LTV?
LTV = Monthly revenue per subscriber × Average lifespan in months. At 2% monthly churn, average lifespan is 50 months. $0.50/month × 50 months = $25 LTV.
What should my max CAC be?
Safe CAC is 30-40% of LTV. At $25 LTV, max CAC is $7.50-$10. This leaves margin for operations, tools, and profit. Aggressive growth might push to 50% temporarily.
How does churn affect newsletter value?
Churn is critical. 2% monthly churn = 50 month lifespan. 5% churn = 20 months - cutting LTV by 60%. Reducing churn from 3% to 2% increases LTV by 50%.
How do I reduce newsletter churn?
Key tactics: Consistent quality, right frequency (test!), segment by engagement, re-engagement campaigns, clean inactive subscribers, and deliver on signup promise.
