How to track newsletter performance beyond open rates

Open rates are unreliable. That's not a hot take, it's just the reality of email tracking in 2026. Apple's Mail Privacy Protection pre-loads tracking pixels, which inflates open rates across the board. Some email clients block tracking entirely. The number you see in your dashboard is, at best, a rough approximation and at worst, genuinely misleading.

This doesn't mean you should ignore opens completely, but it does mean you need to look at other metrics to understand whether your newsletter is actually performing well.

Click-through rate

Click-through rate (the percentage of recipients who click a link in your newsletter) is more reliable than open rate because it requires an actual action from the reader. Someone had to open the email, read something, and decide it was worth clicking.

For curated newsletters, click rates tell you which topics resonate most with your audience. Track which links get the most clicks and you'll start to see patterns. Maybe your readers care more about regulatory updates than market commentary. Maybe practical how-to content outperforms opinion pieces. These patterns should inform what you include in future issues.

A healthy click-through rate varies by industry, but somewhere between 2% and 5% is typical for most newsletter formats. If you're consistently below 2%, the content might not be matching what your audience actually wants.

Reply rate

This is the metric that doesn't show up in most analytics dashboards but tells you more than almost anything else. When a reader hits reply to share a thought, ask a question, or tell you something you missed, that's genuine engagement. It means they're reading closely enough to have an opinion, and they value the relationship enough to respond.

You can encourage replies by asking a specific question at the end of your newsletter, sharing an opinion that invites agreement or disagreement, or simply making it clear that replies go to a real person and not an unmonitored inbox.

There's no industry benchmark for reply rates because most platforms don't track them. But if you're getting even a handful of replies per issue from a list of a few hundred, that's a strong signal.

List growth rate

The absolute number of subscribers matters less than the rate at which your list is growing (or shrinking). A list of 500 that grows by 10% per month is in better shape than a list of 5,000 that's been flat for a year.

Track net growth: new subscribers minus unsubscribes. A healthy newsletter should be growing steadily. If it's flat, your acquisition channels need attention. If it's shrinking, something is wrong with the content, the frequency, or the expectations you're setting when people sign up.

Unsubscribe rate per issue is also worth watching. A small number of unsubscribes with each send is normal and healthy (people's interests change, inboxes get full). A spike in unsubscribes after a particular issue tells you something about that specific content. Pay attention to those spikes.

Engagement over time

One-off metrics for a single issue are less useful than trends over time. A newsletter issue with a low click rate might just mean the content that week was less compelling, or it might mean you sent on a bad day. A consistent downward trend over six issues tells you something much more meaningful.

Track your key metrics over a rolling twelve-week period and look for trends rather than reacting to individual data points. This gives you a clearer picture of whether things are improving, stable, or declining.

Revenue attribution

If your newsletter has a commercial purpose (driving product sales, booking appointments, generating leads), tracking the revenue it generates is the metric that ultimately matters most.

This requires some setup. Use UTM parameters on links in your newsletter so you can track which website visits, sign-ups, or purchases came from email. If you're using a CRM, tag contacts who came through the newsletter so you can measure their lifetime value compared to other channels.

The attribution won't be perfect. Some people will read your newsletter, visit your website later through a Google search, and convert without any direct tracking connecting the two. But even imperfect revenue tracking gives you a much better understanding of the newsletter's value than open rates ever will.

Qualitative signals

Not everything worth measuring shows up in numbers. Pay attention to qualitative signals that indicate your newsletter is working.

Do people mention your newsletter in meetings or on social media? Do potential clients say they've been reading it when they get in touch? Do existing clients reference something you shared? Do industry peers comment on or share items from your newsletter?

These signals are hard to track systematically, but they're some of the strongest evidence that your newsletter is building the kind of reputation and trust that makes a real business difference.

Build a simple dashboard

You don't need sophisticated analytics tools. A simple spreadsheet that tracks these metrics per issue is enough:

Date sent, subject line, number of recipients, open rate (for what it's worth), click-through rate, number of replies, unsubscribes, and any notable qualitative feedback. Update it after each send, review it monthly, and use it to guide your content decisions.

The point isn't to obsess over numbers. It's to make sure you have enough information to know whether your newsletter is doing what you want it to do, and to adjust when it isn't.
