How It Works
Email remains one of the cheapest channels to run and one of the easiest to misjudge. Projecting revenue, return on investment, and value per subscriber for a 2026 program gives you a defensible basis for how much budget the channel deserves and where to push next.
Total revenue comes from multiplying list size by average order value and then by conversion rate. To find ROI, subtract total campaign costs from total revenue, divide the result by total campaign costs, and multiply by 100. Revenue per subscriber is the simplest of the three: total revenue divided by total list size.
Results are only as honest as the inputs, and inflated conversion rates or understated costs will quietly distort everything downstream. Account for the costs that hide in plain sight, such as the hours spent producing content, platform subscription fees, and the overhead of A/B testing. Refresh your figures as the market and your own campaign results shift.
Example: Launching a New Product in Q1 2026
- 1 Input your projected email list size (e.g., 50,000 subscribers), average order value (e.g., $75), estimated conversion rate (e.g., 2.5%), and total campaign costs (e.g., $3,000 for platform, content, and team time).
- 2 The calculator will process these inputs: Total Revenue = 50,000 * $75 * 0.025 = $93,750. ROI = (($93,750 - $3,000) / $3,000) * 100 = 3025%. Revenue per Subscriber = $93,750 / 50,000 = $1.875.
- 3 Your projected total revenue is $93,750, with an impressive ROI of 3025%. Each subscriber is estimated to generate $1.88 in revenue for this campaign.
- 4 This example demonstrates a highly profitable campaign. You can now use these metrics to justify increased investment in email marketing, set realistic performance targets for 2026, and optimize future campaigns to further enhance your ROI and revenue per subscriber.
