How do I calculate email marketing ROI?

Take the revenue your email program generated, subtract what the program cost you over the same period, then divide by that cost: (revenue − cost) ÷ cost × 100. Cost means your email platform bill plus whatever you pay to actually run it — an agency retainer, a freelancer, or the share of a salary spent on email. Both cost fields in this calculator are optional; leave them blank and you get the revenue figures on their own, with no return claimed.

What's Revenue Per Recipient (RPR) and how do I find mine?

Revenue per recipient (RPR) is email-attributed revenue ÷ emails delivered, typically measured per send. Klaviyo and most email service providers report it in campaign analytics. Strong direct-to-consumer (D2C) brands hit $0.15–$0.30 on promotional campaigns; transactional and flow emails can go much higher.

My RPR seems low. Is the list the problem or the content?

Both matter, but content usually comes first. Test subject line relevance, send frequency, and segmentation before blaming the list. If a 10% segment drives 60% of revenue, your broadcast sends are probably suppressing average RPR.

How do I grow owned-channel % of revenue?

Three levers: (1) grow list size via high-intent pop-ups and post-purchase opt-ins, (2) build retention flows — welcome series, browse abandonment, post-purchase, win-back, (3) increase send frequency thoughtfully (weekly minimum for most brands). One set of bands for the share itself: under 15% is under-leveraged, 15–20% is developing, 20–30% is healthy and 30%+ is mature.

Should I include SMS in this calculation?

Not here — this calculator is email-specific. SMS RPR is typically 5–10× higher than email but with much smaller reach. A separate SMS ROI calculation is worth running if you're sending over 50k/month.

How accurate are these calculations?

Our calculators use industry-standard formulas and are designed for directional accuracy. Results depend on the quality of your input data. For precise financial planning, we recommend validating results with your accountant or financial team.

Is this really free? What's the catch?

Yes, completely free with no hidden costs. We offer these tools to help ecommerce brands succeed. We may occasionally share relevant insights via email if you opt in, but the tools remain free forever.

Is my data private and secure?

Your calculations run in your browser, and we don't store the numbers you type unless you choose to send them — by unlocking a benchmark, emailing yourself a report, or contributing an anonymous data point. We do record anonymous usage events, which tool was used rather than what you entered. The AI tools work differently: your store URL and the report or concepts we generate are saved so we can support you and so your share link keeps working. We never access your Shopify admin, your customer data, or any private account information.
