Calculate the conversion rate and revenue from email marketing campaigns. Measure orders per email delivered to optimize your email channel performance.
Email remains the highest-ROI marketing channel for e-commerce, generating $36–42 for every $1 spent. The email conversion rate measures what percentage of delivered emails result in a purchase, giving you a direct line between your email program and revenue.
This calculator computes your email CR from delivered emails and resulting orders, plus revenue per email, open rate, and click-to-purchase efficiency. Use it to benchmark campaigns, compare automated flows vs. broadcast sends, and identify which email types (promotional, abandoned cart, win-back) drive the most revenue.
Average email conversion rates range from 1–5%, with automated flows (abandoned cart, browse abandonment) typically outperforming promotional broadcasts by 3–5×. Understanding these differences helps you allocate resources to the highest-performing email types. Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.
Email is a controlled, owned channel. Measuring its conversion rate precisely allows you to optimize subject lines, send times, content, and segmentation for maximum revenue per send. This calculator turns campaign data into actionable ROI metrics. Having a precise figure at your fingertips empowers better planning and more confident decisions.
Email CR (%) = (Orders from Email / Emails Delivered) × 100 Revenue per Email = Orders × AOV / Emails Delivered Email ROI = (Revenue − Cost) / Cost × 100
Result: 1.50% email conversion rate
With 25,000 emails delivered and 375 orders, the email CR is 375 / 25,000 × 100 = 1.50%. Revenue = 375 × $80 = $30,000. Revenue per email = $1.20. ROI = ($30,000 − $150) / $150 × 100 = 19,900%. Email is remarkably efficient.
Email consistently ranks as the highest-ROI digital channel, generating $36–42 per dollar spent. Unlike social media or paid ads, email reaches an owned audience at near-zero marginal cost. This calculator helps you quantify that advantage.
Automated email flows (triggered by customer behavior) outperform broadcast campaigns by 3–5× in conversion rate and revenue per email. Prioritize setting up abandoned cart, welcome, post-purchase, and browse abandonment flows before investing heavily in promotional calendars.
A mature e-commerce email program generates 25–40% of total store revenue. This stack typically includes: welcome series (5–10%), abandoned cart (10–15%), promotional campaigns (5–10%), and lifecycle flows (5–10%). Each layer adds incremental, compounding revenue.
Promotional broadcasts typically convert at 0.5–2%. Automated flows (abandoned cart, post-purchase) convert at 3–10%. Welcome emails convert at 2–5%. The blended average across all email types is usually 1–3%.
CTR measures clicks per delivered email. Email CR measures purchases per delivered email. CR is a subset of CTR — not everyone who clicks buys. Both are important: CTR measures engagement, CR measures revenue impact.
Per delivery is the standard because it captures your full addressable audience. Per open inflates the rate and is less useful for budget planning. Some teams also track "click-to-purchase rate" as a conversion step metric.
Dramatically. A highly engaged, permission-based list will convert 3–5× better than a cold or purchased list. Regular list hygiene (removing inactive subscribers) improves deliverability and conversion rates simultaneously.
A 24-hour click window is most conservative and accurate. Some platforms default to 5–7 day windows which inflate email attribution. Be consistent and transparent about your attribution model.
Improve targeting (send relevant products to the right segments), optimize landing pages (where do email clicks go?), test incentives (free shipping, discounts), and ensure mobile-responsive design since 60%+ of emails are opened on mobile.
