Frequently Asked Questions

Higher email frequency increases inbox fatigue. Subscribers who feel overwhelmed are more likely to hit unsubscribe or mark emails as spam. Even loyal readers may disengage if they receive too many messages per week, leading to a gradual but measurable rise in churn rate.

Most studies recommend 1–2 emails per week for newsletters. At this cadence, churn risk typically remains below 0.5% monthly. Beyond 3 emails per week, unsubscribe rates often climb quickly. However, the ideal frequency also depends on your content value and audience expectations.

Our model uses an industry-informed baseline: ~0.1% weekly churn for 1 email per week, adding 0.1% for every additional weekly send. The monthly rate is extrapolated by multiplying the weekly rate by 4. The resulting percentage is your estimated monthly unsubscribe rate.

Absolutely. Improve content personalization, let subscribers choose their preferred frequency (preference center), enhance mobile design, and send at optimal times. Strong segmentation ensures recipients only get relevant emails, reducing perceived fatigue.

Track open rates, click-through rates, spam complaints, and list growth rate. A sudden drop in opens or increase in spam complaints may signal frequency issues before unsubscribes spike. Use these leading indicators to fine-tune your cadence.
