Email Marketing Benchmarks 2026 — Open Rates, CTR & More

What Is a Good Open Rate in 2026?

Average email open rates have shifted significantly since Apple's Mail Privacy Protection (MPP) changed how opens are tracked. In 2026, an open rate of 35–45% is considered strong — but this figure is inflated by MPP pre-loading pixels. A more reliable signal is your click-to-open rate (CTOR), which measures clicks against confirmed opens.

Click-Through Rate Benchmarks

Click-through rate (CTR) is often more meaningful than open rate because it measures actual intent — someone saw your email and wanted to act on it. Industry-wide averages sit at 2–3%, but well-segmented campaigns regularly hit 5–8%.

Benchmarks by Industry

Industry matters more than most marketers realise. A 20% open rate is excellent for e-commerce but underwhelming for a B2B SaaS newsletter. Use the table below to benchmark against your own vertical.

Does List Size Matter?

Counterintuitively, smaller lists often outperform larger ones. A list of 2,000 highly engaged subscribers will almost always generate better CTRs and revenue-per-subscriber than a bloated list of 50,000 cold contacts. The key metric to watch is revenue per subscriber (RPS) — calculated by dividing total email revenue by your list size.

• Lists under 1,000: Expect high engagement (40%+ open rates), build relationships personally
• Lists 1,000–10,000: Sweet spot for segmentation, automation starts paying off
• Lists 10,000+: Deliverability management becomes critical, advanced segmentation required

How to Improve Your Numbers

Before chasing better benchmarks, audit your fundamentals:

1. Clean your list quarterly. Remove subscribers who haven't opened in 90+ days. A clean list has better deliverability which lifts all your metrics.
2. Segment ruthlessly. Sending the same email to everyone is the single biggest conversion killer. Segment by behaviour, purchase history, or signup source.
3. Test your subject lines. A/B test every broadcast. Even a 2-word change can swing open rates by 10 percentage points.
4. Send at the right time. Tuesday–Thursday, 9–11am in the recipient's timezone, remains the consistently best window for B2B.
5. Optimise your preview text. The text after your subject line in the inbox is prime real estate — treat it like a second subject line.
