What this means

At $0.14 per subscriber per month, each 1,000 new subscribers is worth about $144/month. The platform is cheap relative to what the list produces; spend effort on list growth and automated flows (welcome, abandoned cart) which typically out-earn campaigns. Open rate (35%) is informational only since it no longer drives revenue directly.

Show the formula
  • Clicks = subscribers × campaigns × click rate
  • Orders = clicks × purchase rate
  • Revenue = orders × AOV
  • ROI = (revenue − platform cost) ÷ platform cost
