Email Rate Benchmark Guide

What Are Good Email Open, Click, and Unsubscribe Rates?

Email benchmarks vary significantly by industry, list size, and sending frequency — which is why generic "average open rate is 21%" figures are almost useless in isolation. B2B newsletters consistently outperform B2C promotional emails on open rate, often reaching 35–50% for highly engaged niche lists. E-commerce promotional emails average 15–20% open rates but compensate with high send frequency and revenue per email. Creator newsletters with a strong personal voice and a loyal audience regularly see 40–60% open rates. Your benchmark is your own historical performance, measured against industry-specific averages for your category.

The metric most marketers obsess over — open rate — became significantly less reliable after Apple's Mail Privacy Protection (MPP) launched in 2021, which pre-loads email tracking pixels regardless of whether the user actually opens the email. If a significant portion of your list uses Apple Mail, your reported open rate may be inflated by 10–20 percentage points. Click rate and click-to-open rate (CTOR) are now more reliable engagement indicators than raw open rate for lists with high Apple Mail usage.

The Metrics That Actually Predict Revenue

The email metrics most directly correlated with revenue are click rate (how many subscribers actually engage with your CTA), conversion rate on the destination page (how many clickers complete the desired action), and revenue per email sent (total campaign revenue divided by emails delivered). Open rate is a leading indicator of deliverability and subject line quality, not revenue. An email with a 40% open rate but 0.5% click rate is underperforming an email with a 25% open rate and 3% click rate — the second email is driving 2.5x more traffic to your offer despite the lower open rate.

Unsubscribe rate is your feedback signal on relevance and frequency. An unsubscribe rate above 0.5% per campaign typically indicates either a relevance problem (you sent something off-topic for your audience) or a frequency problem (you're sending too often for the value you're delivering). Below 0.2% is healthy. Spam complaint rate is even more critical — above 0.1% triggers deliverability warnings from most ESPs and above 0.3% risks domain-level blacklisting. Keep complaint rates near zero by making it easy to unsubscribe and never sending to purchased or scraped lists.

How to Improve Below-Benchmark Performance

If your open rate is below benchmark: test subject lines more aggressively (aim for 3–5 variants per campaign), clean your list of cold subscribers who are dragging down your engagement rate, and check your sender reputation using tools like Google Postmaster. If your click rate is below benchmark: make your CTA more prominent and more specific, reduce the number of links per email (one clear CTA consistently outperforms three competing ones), and ensure the email content builds toward the CTA rather than burying it. If your unsubscribe rate is high: survey recent unsubscribers to find out whether the issue is frequency, relevance, or expectations mismatch from your sign-up process.
