Newsletter performance hinges on a few key numbers you can track to improve engagement: open rate, click-through rate, unsubscribe rate and conversion rate. By focusing on what your readers do, you learn which subject lines, content and CTAs resonate. Track “open rate” and “click-to-open” to gauge interest, then iterate.

Understanding Engagement Metrics
Engagement metrics break down how your readers interact after delivery: opens, clicks, conversions, and unsubscribes. You should compare your numbers to industry benchmarks—many sectors report 20–25% open rates and 2–5% CTRs—and prioritize the metric that links directly to your goal, whether sales, sign-ups, or content consumption; small iterative tests often produce 10–30% relative improvements.
Open Rates: What They Mean for You
Open rates measure subject-line appeal and inbox placement but don’t guarantee interest, since image-blocking and previews can count as opens. Target 20–30% as a healthy range; if you’re under 15%, test sender name, subject personalization, and list hygiene. For instance, a niche newsletter lifted opens from 14% to 27% after segmenting by past engagement and A/B testing subject lines.
Click-Through Rates: Gauging Interest
Click-through rates show whether your content and CTAs drive action—typical benchmarks sit between 2% and 6% depending on offer and list quality. Focus on a single, clear CTA, concise copy, and mobile-first buttons; one ecommerce campaign increased CTR from 1.9% to 5.2% by simplifying copy and moving the CTA above the fold.
To lift CTR, you should instrument links with UTM tags, segment by past clicks, and A/B test CTA text, color, and placement; top senders also resend to non-clickers and see up to a 30% lift. “A single, bold CTA outperforms multiple competing links,” noted a case where retargeting non-clickers converted at 6%.

Subscriber Growth
Track net subscriber growth with (new subscribers − unsubscribes) ÷ starting list and aim for steady gains—3–5% monthly is a solid benchmark. For instance, a 10,000 list that gains 400 and loses 100 nets (400−100)/10,000 = 3% growth. Compare month-over-month and quarter-over-quarter to spot accelerating or slowing trends and prioritize channels that deliver the highest-quality additions.
Tracking New Subscribers
Instrument every signup with UTMs so you can attribute where new subscribers come from: pop-ups, blog posts, paid ads, or referrals. If a blog post with 2,000 visitors converts at 5%, that’s 100 new subs; A/B a headline and CTA to lift conversion to 6% (120 subs). Track cost-per-acquisition and lifetime value by source to focus acquisition spend.
Monitoring Unsubscribes
Monitor unsubscribe rate per send—industry averages sit around 0.2–0.5%—and watch for sustained increases. A jump from 0.3% to 1.5% after one campaign flags an issue with content, frequency, or deliverability. Break the metric down by segment, subject line, and send time to diagnose whether a single audience or the whole list is reacting.
Dig into unsubscribe feedback: run a one-question exit survey and segment users by reason to quantify patterns. If you see a campaign-driven jump, pause similar sends and compare bounce and complaint rates; re-engagement campaigns often recover 10–30% of inactive subscribers, so test a targeted 3-email series. “A sudden spike often traces back to a bad send.” Try MailerLite for easy A/B tests and automation: https://www.mailerlite.com/a/q1bbyrcjpw
Content Performance
You should map opens, clicks, read depth and shares to identify what truly moves your audience; often ~20% of issues drive ~80% of engagement, so focus on those patterns. Track open rate, click-through rate, time-on-article and unsubscribe delta by segment, then correlate with send time and subject line. For a compact metric list, see 12 Newsletter Metrics You Need to be Tracking.
Analyzing Top-Performing Articles
Compare headline formulas, word count, and lead hooks: a 400–600 word how-to with a bold data point often outperforms a 1,200-word feature in CTR. Look for articles with >20% CTR or 3× average click volume as models, then replicate their structure, tone and CTAs while testing variations across 30- and 90-day cohorts.
Feedback and Reader Surveys
Run ultra-short surveys (1 NPS + 2 targeted questions) and expect 5–10% response on cold lists, 15–30% on engaged segments; segment answers by subscription age and opens to prioritize fixes. Use open-text fields sparingly and tag responses to match content themes so you can act on the highest-impact requests.
“Your readers will tell you more than analytics ever could.” Run quarterly 5-question surveys, A/B one survey CTA, and aim to implement the top three suggestions each month; you can streamline this with a tool—Start MailerLite free trial.
Revenue Metrics
You should segment revenue by channel—ads, sponsorships, affiliate sales, and paid subscriptions—to spot what scales. For example, a niche newsletter with 15,000 active opens can earn $500–$1,500/month from sponsorships at $30–$100 CPM, while affiliates contributing a 2–4% conversion rate on promoted products often drive steady recurring income. Track RPM (revenue per thousand opens) and trend it weekly to catch drops or spikes tied to content or list quality.
Measuring Ad Performance
Start with CTR, CPM, and RPM; each tells a different story. If you sell a $75 CPM slot to a 20,000-open list, that’s $1,500 gross, but a 0.8% CTR (160 clicks) shows engagement; native ads often convert 2–4× higher than banners. Use A/B tests on subject lines and placement, and check viewability and unsubscribe lift—a high CPM with increased unsubscribes isn’t sustainable.
Tracking Affiliate Links
Use UTM parameters, unique promo codes, and a link-tracking platform to attribute conversions reliably. Many affiliate programs convert at 1–5%, so if you drive 1,000 clicks with a 2% conversion rate and $80 average order value, that’s $1,600 gross. You should also monitor cookie duration and whether last-click attribution understates first-touch influence from early funnel content.
Consider server-side tracking and unique coupon codes to close attribution gaps; “longer cookie windows can lift reported commissions” by capturing late buyers. Test increasing cookie duration from 7 to 30 days—some publishers see ~15–25% more tracked revenue. Try your tracking setup and automations with MailerLite: https://www.mailerlite.com/a/q1bbyrcjpw
Audience Analysis
Demographic Insights
Look at age, location and device splits: if 60% of your subscribers are 25–34 and 70% open on mobile, you prioritize short subject lines and single-column templates. Also check time zones—sending at 10:00 local often lifts opens by 8–12% versus a one-size-fits-all send. Use this data to tailor offers by region and peak hours.
Segmenting Your Audience
Use behavioral segments—last 30 days opens, past purchases, or clicked links—to match content to intent. For example, isolating subscribers active in the past 30 days can raise open rates by 15% and CTRs by 10%. Combine with simple tags like “buyer” or “trial-user” to send timely, relevant messages.
For deeper impact, create multi-condition segments (location + purchase recency + last click) and run targeted flows: a B2C test that layered product interest with cart abandonment saw conversions jump 35%. “Subscribers who clicked a product link are 3x more likely to convert.” Try A/B testing subject lines per segment and set a 3-email win-back cadence; experiment with segmentation tools at https://www.mailerlite.com/a/q1bbyrcjpw
Best Practices for Measuring Success
Focus on the handful of metrics that move revenue and engagement: open rate, click-through rate (CTR), conversion rate, deliverability, list growth and churn, and revenue per subscriber. Track open rates (typical 15–30%), CTRs (2–5%+), and conversion goals tied to a dollar value. Use cohort analysis to spot where engagement drops after 2–4 sends, and prioritize tests that lift CTR or conversion by at least 0.5–1 percentage point.
Setting Goals and Benchmarks
Set SMART goals and baseline benchmarks from your first 1,000 subscribers. For newsletters, aim for 15–25% open rate, 2–5% CTR, and 3–5% monthly list growth; if you sell products, target 1–3% conversion or $0.50–$2 revenue per subscriber. Use A/B testing on subject lines and segmentation—one SaaS newsletter boosted CTR from 1% to 3% after testing two subject-line variants.
Tools to Simplify Tracking
Use an integrated stack: your ESP for opens and clicks, Google Analytics with UTM tags for on-site behavior, and a BI tool or spreadsheet for revenue per subscriber. Connect e-commerce platforms like Shopify or Stripe to map purchases back to campaigns, and leverage automation to tag subscribers by behavior so you can benchmark cohorts quickly.
For deeper tracking, combine your ESP’s campaign reports with event analytics (Mixpanel or GA4) to assign revenue to campaigns and measure lifetime value. As one growth lead said, “seeing revenue per subscriber changed our send strategy.” MailerLite, for example, offers UTM support, e-commerce integrations, and automation reports so you can attribute purchases to campaigns—try it: https://www.mailerlite.com/a/q1bbyrcjpw
