What gets measured on your Substack dashboard? Open rate, click rate, subscriber growth, and revenue if you run paid tiers. Which ones actually tell you whether your newsletter is healthy?
Most new publishers obsess over subscriber count while ignoring open rate. A list of 2,000 subscribers with a fifteen percent open rate is weaker than 500 subscribers opening at fifty percent. Analytics help you see the difference and adjust before wasting months on the wrong priorities.
Here are the Substack analytics that matter and how to act on them.
Core metrics to track
Open rate shows what percentage of subscribers opened your issue. Industry averages for newsletters range from twenty to forty percent. Above forty percent indicates strong reader loyalty. Below twenty percent suggests subject line problems, inconsistent publishing, or audience mismatch.
Click rate measures how many opened readers clicked a link in your issue. Low clicks with high opens mean your content engages but your calls to action need work. High clicks validate that readers trust your recommendations enough to act.
Subscriber growth rate tracks net new subscribers minus unsubscribes over time. Steady growth with low unsubscribe rates signals healthy expansion. Spikes followed by mass unsubscribes suggest promotional tactics that attracted the wrong audience.
What the numbers tell you
Declining open rates over three or more issues point to content fatigue, off-topic issues, or sending too frequently. Review your last five subject lines and topics for patterns that correlate with drops.
High unsubscribes after a specific issue mean that issue violated reader expectations. Too promotional, too off-topic, or too long are common triggers. Note what changed and avoid repeating it.
Low click rates on issues with strong opens suggest you are writing engaging content but not giving readers a clear next step. Add one relevant link per issue and track whether clicks improve.
Improving performance over time
Review analytics after every five issues, not after every single send. Daily obsessing over numbers creates anxiety without actionable insight. Monthly reviews reveal trends that individual issue data hides.
Test one variable at a time. Change your subject line format for three issues and compare open rates. Then test send day or time. Isolated tests tell you what actually works for your audience.
Compare your metrics against your own history, not other publications. A niche B2B newsletter at thirty-five percent open rate may outperform a general interest newsletter at twenty-five percent even though the numbers look similar.

Frequently asked questions
What is a good open rate for a Substack newsletter?
Thirty to forty percent is solid for most publications. Above forty percent indicates strong reader loyalty. Below twenty percent warrants investigation into subject lines, sending frequency, and content relevance. Compare against your own trend line rather than industry averages alone.

Does Substack show who opened your emails individually?
Substack shows aggregate open and click data, not individual reader behavior. You see overall percentages and trends, not which specific subscriber opened issue twelve. This protects reader privacy while giving you enough data to optimize content.
How do you track whether Substack drives website traffic?
Use link tracking in your issues and review click data in Substack analytics. For deeper insight, compare website traffic sources in your site analytics during the days after each issue sends. Spikes in direct or referral traffic often correlate with newsletter sends.
Should you remove inactive subscribers to improve open rates?
Yes, periodically. Subscribers who have not opened in three to six months drag down your metrics and may hurt deliverability. Send a re-engagement issue first. Remove those who do not respond. A smaller engaged list outperforms a large inactive one.
What revenue metrics matter for paid newsletters?
Track paid subscriber count, monthly recurring revenue, free-to-paid conversion rate, and paid churn rate. Conversion rate above three percent and monthly churn below five percent indicate healthy paid performance. See Substack monetization and paid subscriptions for pricing strategy.
How often should you review Substack analytics?
Check basic numbers after each issue sends to catch obvious problems. Do a deeper review monthly to identify trends. Quarterly reviews should inform strategy shifts like topic changes, format experiments, or monetization timing. See advanced Substack brand tactics for strategic adjustments.
