AI-Powered Email Campaign ROI Simulator & Subject Line Optimizer

Stop guessing. Instantly forecast opens, clicks, conversions, and revenue for any email campaign. Test subject line variations with AI-driven benchmarks across industries—optimize performance before you hit “Send.”

Why Email Campaign Simulation Matters

Email remains one of the highest-ROI channels, but open rates can vary from 10% to 50% depending on industry, list freshness, and subject line quality. Low click-through rates waste your audience, while poor conversion rates undermine your revenue projections. Traditional A/B tests take weeks and expose you to guesswork. Our browser-based simulator consolidates industry benchmarks for opens, clicks, conversions, and revenue-per-conversion into an interactive tool. Instantly compare subject line variations, adjust list size and industry, and plan every campaign with data-backed confidence.

How It Works

We embed a client-side dataset of five industries—E-commerce, SaaS, B2B Services, Non-profit, and Blogging—each annotated with average:

• Open Rate (%) per subject line
• Click-Through Rate (%) per open
• Conversion Rate (%) per click
• Revenue per Conversion (USD)

Enter your list size, select industry, choose number of subject-line variations, and click “Simulate Campaign.” JavaScript calculates:

1. Projected Opens = listSize × openRate
2. Projected Clicks = opens × clickRate
3. Projected Conversions = clicks × conversionRate
4. Estimated Revenue = conversions × revenuePerConversion
