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.

A/B Testing
A/B testing in email marketing is the practice of sending two variations of an email to a small sample of your list to determine which version performs better before sending the winner to the remaining subscribers.
Abandoned Cart Email
An abandoned cart email is an automated message sent to customers who added items to their online shopping cart but left without completing the purchase. It is one of the highest-converting email types in ecommerce.
Abuse Complaint
An abuse complaint is a report from a recipient who marks an email as spam, which negatively affects sender reputation and deliverability.
AI Email Summary
An AI email summary is a short, machine-generated overview of an email's key points, shown by Gmail, Outlook and Apple Mail before a recipient opens the message. It is reshaping how email marketers think about subject lines, preview text and open rates.
AI Inbox Summary
An AI inbox summary is an AI-generated digest that condenses unread email — often highlighting news, actions and senders — changing how clearly your marketing email reaches and engages subscribers.
AI Inbox
An AI inbox is an email client that uses artificial intelligence to summarise, sort, prioritise and sometimes answer emails before the human recipient reads them. It is transforming email marketing metrics and copywriting.
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.
