Free Email Flow ROI Tracker — Welcome, Cart, Post-Purchase, Winback

Calculate ROI per email flow: revenue, COGS, and cost (e.g. Klaviyo). Get ROI % and simple fix notes for each flow. Free calculator, manual inputs.

What is the Email Flow ROI Tracker?

It calculates profit and ROI % for each major email flow (welcome, abandoned cart, post-purchase, winback) using flow revenue, COGS, and flow cost. You get a short “fix this flow” note for underperformers—e.g. reduce cost, improve conversion, or scale winners.

Enter revenue, COGS, and cost (your share of Klaviyo or other platform cost per flow). We use the same ROI logic as our ROI Calculator: profit = revenue − COGS − cost; ROI % = (profit ÷ cost) × 100. No Klaviyo API—manual inputs only.

Flow cost = share of email platform cost (e.g. Klaviyo) you assign to this flow, or other direct cost. Use your last 30–90 days of flow revenue and COGS for a fair comparison.

How to use your results

Fix or pause flows with negative or very low ROI; scale flows with strong ROI. Use our ROI Calculator for campaign-level ROI and LTV Calculator for customer value. See the tools hub for more.

FAQ

How do I get flow revenue and COGS?
In Klaviyo (or your ESP), use flow performance reports for revenue attributed to each flow. COGS = cost of goods for orders that came from that flow. Flow cost = your share of the platform fee for that flow, or other direct cost.
What is a good email flow ROI?
Many healthy flows show 100–300%+ ROI. Negative or very low ROI means the flow is not profitable after COGS and cost—optimize or pause and rework.
Is this email flow ROI tracker free?
Yes. Free with no signup. Manual inputs only; we do not connect to Klaviyo. For campaign ROI see our ROI Calculator and Ecommerce Campaign Tool.
