How to use it

  1. Enter your email list size, open rate, click-through rate of opens, conversion rate of clicks, average order value, total campaign cost (including design and tool fees), and expected unsubscribe rate.
  2. Read projected revenue, ROI, profit, cost per acquisition, revenue per subscriber, and break-even conversion rate. The break-even conversion rate tells you the minimum click-to-purchase rate needed to cover costs.
  3. Interpret the revenue vs cost chart to see if the campaign is structurally profitable or marginal. If CPA exceeds AOV, the campaign is loss-making at current rates regardless of volume.
  4. Act on the output by fixing the weakest funnel stage first. A low open rate is a subject-line and deliverability problem. Low CTR is a copy or offer problem. Low conversion rate is a landing page or checkout problem.
  5. Re-run before each campaign with updated list health metrics. Track revenue per subscriber over time — a declining RPS is an early signal that list quality is degrading or the offer is fatiguing the audience.
Questions people usually ask
What is email marketing ROI?

Email marketing ROI is the net profit from a campaign divided by the total campaign cost, expressed as a percentage. The industry average email marketing ROI is often cited at 3600-4200% ($36-42 per $1 spent), though this varies widely by list quality and offer.

What are good open and click-through rates?

Industry averages: open rate 20-25%, CTR (of opens) 2-5%. Rates above these suggest a high-quality list and relevant content. Rates well below average often indicate deliverability problems or a misaligned audience.

How is break-even conversion rate calculated?

Break-even conversion rate = (Campaign Cost ÷ Average Order Value) ÷ Total Clicks × 100. It tells you the minimum percentage of people who click that must purchase to cover your campaign costs.

What is cost per acquisition in email marketing?

CPA = Campaign Cost ÷ Total Conversions. It measures how much you spent to generate each sale or lead. Compare this to your product margin and customer LTV to determine if the campaign is profitable at scale.
