Email Marketing Performance Metrics
Email marketing remains one of the highest-ROI channels available to Australian small businesses. But raw subscriber numbers tell only part of the story — the real performance indicators are the metrics that reveal how your audience engages with your campaigns. Our free email marketing calculators help you benchmark, analyse, and improve the metrics that matter most.
Why Email Open Rate Matters
Your email open rate is the percentage of delivered emails that recipients actually opened. Industry benchmarks vary significantly: B2B email averages 21-25% open rates, while eCommerce typically sees 15-20%. A strong open rate signals a healthy sender reputation, relevant subject lines, and an engaged subscriber list. Use our Email Open Rate Calculator to calculate your rate instantly and compare it to industry norms.
List Growth: The Long-Term Asset
An email list that isn’t growing is shrinking — industry attrition rates average 22-25% annually as subscribers change jobs, change interests, or unsubscribe. Your list growth rate measures whether new sign-ups are outpacing churn. A healthy monthly growth rate of 2-5% indicates your lead generation is working. Track your progress with our Email List Growth Rate Calculator.
Click-Through Rate: The Engagement Signal
Click-through rate (CTR) measures the percentage of recipients who clicked a link in your email. Average CTR across industries is 2-5%. CTR depends on your offer relevance, CTA placement, and audience segmentation. Our CTR Calculator lets you benchmark your campaigns instantly.

How to Improve Your Email Marketing Performance
- Clean your list regularly. Remove subscribers who have not opened an email in 6 months. A smaller, engaged list outperforms a large, disengaged one in both metrics and deliverability.
- Segment by behaviour. Send different content to new subscribers, active buyers, and lapsed contacts. Segmented campaigns produce 14% higher open rates and 100% higher click rates than unsegmented sends.
- Test subject lines. A/B test two subject lines on 20% of your list, then send the winner to the remaining 80%. Small improvements in open rate compound significantly over thousands of emails.
- Optimise send timing. Tuesday through Thursday mornings (8–10am in your audience’s time zone) typically see the highest open rates. Test your specific audience — results vary.
- Improve email body copy. One clear call-to-action per email outperforms multiple competing CTAs. Make the desired next step obvious and frictionless.
