Definition
Email marketing ROI benchmarks are industry-specific data points that show the average financial return businesses achieve from their email marketing investment. These benchmarks help marketers set realistic targets, evaluate performance, and build business cases for email investment.
ROI benchmarks vary significantly by industry, business model, and programme maturity. Comparing your email ROI against relevant benchmarks provides context for whether your programme is underperforming, meeting expectations, or exceeding industry standards.

How to Calculate Your Email ROI
Email ROI (%) = (Email Revenue - Email Cost) / Email Cost x 100
Include all costs: ESP platform fees, team salaries (prorated), creative production, deliverability tools, and list building costs. Attribute revenue using your chosen attribution model (last-click, multi-touch, or custom). Compare against industry benchmarks to evaluate performance.

Frequently Asked Questions
A good email ROI is above 2,000% (20:1). An excellent email ROI is above 5,000% (50:1). Email marketing consistently outperforms other channels by a wide margin. If your email ROI is below 500% (5:1), there are significant optimisation opportunities.
Use the revenue and cost data from your email programme to calculate your actual ROI. Compare against the industry benchmarks above. If you are below the median, focus on the areas that drive the largest ROI improvements — automation, segmentation, and personalisation.
Most benchmarks use total programme costs including list building. Some benchmarks separate list building costs because they vary significantly by industry and acquisition channel. Check the methodology of any benchmark you use for comparison.
Email ROI typically improves over the first 12-24 months of a programme as list engagement matures, automation is implemented, and data for personalisation accumulates. Mature programmes (2+ years) typically have 30-50% higher ROI than new programmes.
Implementing automated email sequences (welcome, abandoned cart, post-purchase) produces the fastest ROI improvement for most programmes. Automation generates 3-5x more revenue per send than broadcast campaigns and requires minimal ongoing cost after initial setup.
