What is a Substack stats card?
A Substack stats card summarizes a publication's health: subscribers, open rate, posts published in the period, and comments received. Subscribers and open rate are the two metrics that genuinely matter — open rate above 40% signals a healthy list, below 20% suggests churn or bad subject lines. Substack writers post stats cards at end-of-year, when crossing subscriber thresholds (1K, 10K, 100K), or after a viral post. The format works because newsletter readers are accountability-minded — sharing your numbers (good or bad) builds trust with the people who pay you. The Hub Tools generator pre-loads the four canonical Substack metrics and defaults to a warm rust background. Pair it with the QR Code Generator for a Substack-link QR or the Screenshot Mockup Generator for a Substack-page mock.

About Substack publication analytics
Substack surfaces four metric planes: Subscribers (free + paid), Posts (open rate, click rate), Audience (geography, referrers, source), and Revenue (MRR, churn).
- Open rate counts unique opens within 24 hours of send (Apple Mail Privacy Protection inflates this number in iOS)
- Click rate is unique clicks ÷ unique opens, typically 5-15% for healthy newsletters
- Substack network = recommendations from other publications; can drive 30-50% of new free subs at scale
- Paid conversion = paid subscribers ÷ total free subs × 100; healthy newsletters target 5-10%
