SubStat · expanded stats for Substack

See what your Substack dashboard hides: who reads to the end, who unsubscribes after each email, and who’s about to cancel.

Your Substack dashboard shows opens and views. SubStat shows what they don't tell you. • Your latest post, in plain words. "Of the 1,297 who opened it, only 19 read to the end." "9 people unsubscribed in the next 24 hours." Every number compared with your usual email. • What you didn't know. How many people your emails drive away vs. how many they bring, how many haven't opened anything in 6 months, how much more your paid subscribers open than your free ones. • Your money at risk. Paid subscribers who already cancelled but still have access, and the ones who pay but barely read you. Why people cancel, and which plan keeps them longest. • One-click segments. Upgrade candidates, people leaving soon, dormant readers… created in your Substack so you can email just them. • Inside your dashboard. SubStat adds a section to your Substack sidebar, alerts next to Posts, Subscribers or Revenue, and a "Today" card with the one thing to look at. • Trends month by month and vs. last year, your records, and who to collaborate with from Creator Matches. Private by design. SubStat reads your stats inside your browser and never sends them anywhere. No account, no tracking: our only server just checks license keys. It only writes to Substack when you create a segment. 7 days of everything, free. Then keep the report for your last 3 posts, the "Today" card and the alerts for free, or unlock everything with a one-time payment (no subscription), 12 months of updates included.
