How to Calculate Email Marketing ROI

Email consistently delivers the highest ROI of any marketing channel — averaging $36–$42 for every $1 spent according to Litmus and Klaviyo data. But the real power is in tracking your per-subscriber revenue, which reveals the true asset value of your list.

Monthly Revenue = List Size × Sends × Click Rate × Conv Rate × Purchase Value
Revenue per Subscriber = Monthly Revenue ÷ List Size
Revenue per Send = Monthly Revenue ÷ Sends per Month
Annual List Value = Revenue per Subscriber × 12 × List Size
Break-Even Subscribers = Platform Cost ÷ Revenue per Subscriber
ROI = ((Revenue − Platform Cost) ÷ Platform Cost) × 100%

Frequently Asked Questions

What is a good email open rate?
The average email open rate across industries is 20–25% (2024 data). A "good" open rate is 30%+ and exceptional is 40%+. Open rates vary significantly by industry — B2B and newsletters average higher (25–35%) while promotional retail emails often sit at 15–20%. Focus on list hygiene, strong subject lines, and sending to engaged segments to keep rates high.
How do I calculate revenue per subscriber?
Revenue per subscriber (RPS) = Monthly Email Revenue ÷ Total Subscribers. A healthy eCommerce email list generates $0.50–$2.00 per subscriber per month. For newsletters, $0.10–$0.50/sub/month is typical. RPS is the key metric for valuing your list as an asset — if you were to sell or acquire an email list, buyers often pay 12–24 months of RPS as a valuation multiple.
