Email Marketing ROI Calculator — See If Your Campaigns Are Profitable
Calculate your email marketing ROI in 30 seconds. Enter revenue and true campaign cost — platform fees, copywriting, design time, tools — and see your real return, net profit and revenue per email.
Before you calculate
Most marketers only count their ESP subscription cost. Your true campaign cost includes copywriting time, design hours, list management, testing tools, and any paid acquisition. Missing these inflates your ROI.
How Email ROI is Calculated
ROI = ((Revenue − Campaign Cost) ÷ Campaign Cost) × 100
Net Profit = Revenue Generated − Total Campaign Cost
Revenue per Email = Total Revenue ÷ Emails Sent
Break-Even Orders = Campaign Cost ÷ Average Order Value (rounded up). This covers campaign cost from revenue alone; it excludes product costs, returns and other order-level expenses.
Campaign cost should include all costs associated with producing and sending the campaign: email platform fees, list management, copywriting, design, and any paid promotion.
Understanding Email Marketing ROI
Email ROI depends on the revenue attributed to a campaign and the costs included. Compare campaigns using consistent definitions rather than assuming a universal industry average.
Calculating email ROI accurately requires accounting for all associated costs, not just your email platform subscription. Design time, copywriting, list management, testing, and any paid acquisition costs used to build the list should all factor in. When you capture total cost alongside total attributed revenue, you get a genuine picture of profitability — one that holds up to scrutiny from stakeholders and justifies further investment in the channel.
Revenue Attribution and What Counts
Attribution windows and models differ between platforms. Attributed revenue is not necessarily incremental revenue: some customers might have purchased anyway. Compare consistent attribution windows and, where possible, use a holdout test to estimate incremental impact.
Improving Email ROI Over Time
Revenue per email and cost per email are useful levers to investigate. Test segmentation and automation against comparable campaigns, and account for changes in platform costs as your list grows.
Track your ROI campaign by campaign using this calculator to build a clear picture of which sends perform best, and use that data to guide where you focus creative and budget in future campaigns.
