A healthy churn rate for newsletters is typically around 2-5% per month. Anything higher might indicate irrelevant content.
Email list growth is rarely linear. It follows a compound curve. As your list grows, your content gets shared more often, leading to more referral signups. This calculator models that growth trajectory, factoring in the critical 'Leaky Bucket' variable: Churn.
Churn is percentage-based, meaning it gets more painful as you grow. 2% churn on 100 subs is only 2 people. 2% churn on 100,000 subs is 2,000 people leaving every month. You must outrun your churn to grow.
An average newsletter sees 2-5% churn per month. B2B newsletters often have lower churn (1-2%) than B2C. If your churn is >5%, you may be sending content that isn't relevant, or you might have attracted low-quality leads via a deceptive giveaway.
This is usually due to the 'Churn Equilibrium'. As your list grows, the absolute number of people leaving (e.g., 5% of 10,000 = 500) eventually equals your new signups. To break a plateau, you must either increase traffic sources or decrease churn.
List cleaning involves deleting subscribers who haven't opened an email in 6 months. While it hurts your 'vanity metrics' (total count), it improves your 'Open Rate' and 'Deliverability'. ISPs like Gmail trust high-engagement lists and are less likely to mark you as spam.
Frequency is less important than consistency. Whether it's daily, weekly, or monthly, sticking to a schedule builds a habit for your readers. 'Ghosting' your list for months and then reappearing is a guaranteed way to spike unsubscribe rates.
In 2024, thanks to Apple's MPL (Mail Privacy Protection), open rates are inflated. However, a target of 35-45% is considered healthy. Anything below 20% signals a problem with your subject lines or list quality.
Never. Bought lists are 'Cold Traffic'—they don't know who you are. This leads to massive spam reports, which will taint your domain reputation and ensure your legitimate emails also go to junk folders. Grow organically.
A process where a user signs up and then must click a confirmation link in their email. This slows down growth by about 20% but results in a infinitely higher quality list with much lower churn rates.
Tools like SparkLoop or viral loops allow you to reward subscribers for bringing in friends (e.g., 'Refer 5 friends to get a free t-shirt'). This turns your audience into a sales team.
This depends on your monetization. If you sell a $100 product to 1% of your list monthly, each subscriber is worth $1/month. Knowing this value helps you decide how much to spend on paid ads (CPA).
