Is Substack Newsletter Audit worth $15 if your newsletter health lives in a dozen tabs?
If you run a Substack and your performance story is scattered across open rates, subscriber growth, paid churn, and a pile of post-level numbers, the first problem is not a bad strategy. It is that the data is hard to compare. Substack Newsletter Audit is a $15 Chrome extension that tries to fix that by pulling key Substack analytics into one local dashboard and scoring the numbers against benchmarks. It is aimed at creators who want a fast health check, not another tab to babysit.

What you’re actually buying
At $15, the value is not a big bundle of files. It is a focused audit layer for your existing Substack account. The extension is built around the 7 Revenue Predictors: open rate, click-through rate, click-to-open rate, free-to-paid conversion, monthly list growth, paid subscriber churn, and paid unsubscribe rate. Each metric is color-coded so you can see at a glance whether a number is strong, average, or needs attention.
The second half is where it becomes useful for editorial decisions. The content performance view gives you a sortable look at your posts, including clicks and paid conversions, so you can spot what actually moves readers. The audience insights panel adds free-versus-paid breakdown, location, and overlapping publications, which can help with collaboration ideas. Growth and monetization views round it out: traffic/signup sources, ARR, subscription tiers, churn, and lifetime value, all in one place.
The setup is local. You load the extension in Chrome, log into Substack, enter your newsletter URL, and view the audit dashboard. Your data is processed in the browser and is not sent to external servers, which makes it a reasonable fit if you prefer keeping analytics close to your own login session.
Why it’s on our radar
The public page shows 6 ratings averaging 5.0 stars and about 49 visible sales. That is not a huge crowd, but it is enough to suggest the tool has already found a real niche among Substack creators. For a $15 extension, the rating signal is simple: people who bought it for a quick audit seem satisfied.
What actually matters
- Fit: This is for Substack creators who want a recurring health check, not a one-off CSV export. If you publish regularly, the dashboard can save you from toggling between analytics screens.
- Setup: It is a Chrome extension, so you will need to unzip the download and load it as an unpacked extension. If you are comfortable with Chrome developer settings, this is quick; if not, that small step may be the main friction.
- Pricing: The standard price is $15, but the offer mentions launch-tier codes for early downloads. Check launch pricing codes to see whether a lower tier is still active before paying full price.
- Privacy: The extension reads from your existing Substack session and processes data locally. That is a plus if you do not want another service storing your newsletter metrics.

Bottom line
If your Substack analytics feel like a puzzle made of too many tabs, Substack Newsletter Audit is a cheap way to get a clearer picture. It is not a growth service, and it will not fix a weak strategy, but it can make your numbers easier to read, compare, and act on. For creators who want a local, benchmarked view of their newsletter health, $15 is a reasonable price to stop guessing.
