Learn what it is, why it matters, how to calculate it, and how to improve your email campaign profitability. Formula Email ROI (%) · \= · \[(Revenue – Cost)Cost\] · × 100 **Example.** If your email campaign generated $10,000 in revenue and cost $1,000 to run, your Email ROI would be 900%. ## Overview ## What it is Email ROI measures the financial return generated by your email marketing efforts compared to the total cost. It helps determine whether your email campaigns are profitable and how efficiently they’re driving revenue. ## Why it matters Email ROI is essential for understanding the effectiveness and profitability of your email strategy. A high ROI shows that your messaging, targeting, and timing are driving real business value. ## How it is calculated Email ROI is calculated by subtracting your total email marketing costs from the revenue generated, dividing the result by the cost, and then multiplying by 100 to express it as a percentage. ## Good and bad values ## A good value A good Email ROI is often considered 300% or higher, meaning you earn $3 or more for every $1 spent. Many well-optimized email programs achieve much higher returns. ## A bad value A low or negative ROI indicates that your email campaigns aren’t generating enough revenue to cover their costs. This may result from poor targeting, irrelevant content, or lack of optimization. ## Do Use these tactics to improve ROI and drive more revenue from your email marketing. 1. 01 ### Segment your audience Personalize content and offers based on user behavior or preferences to improve engagement and drive more conversions. 2. 02 ### Automate lifecycle campaigns Use triggered emails – such as welcome series, cart abandonment, or reactivation flows – to drive consistent revenue. 3. 03 ### Track revenue per campaign Connect your email platform to your sales data to understand which campaigns generate the most revenue and why. ## Avoid 1. Ignoring revenue attribution, not A/B testing subject lines, or failing to optimize send times can all reduce ROI. Always measure, test, and iterate to improve results. ## Related metrics ## Related metrics you might be interested in [Goal Completion Rate`= (Number of Goal Completions ÷ Total Sessions) × 100`](/metrics/goal-completion-rate) [Goal Conversion Rate`= (Goal Completions ÷ Total Sessions) × 100`](/metrics/goal-conversion-rate) [Google Ads Conversion Rate`= (Conversions / Clicks) × 100`](/metrics/google-ads-conversion-rate) [Google Ads Impressions`= Total Number of Times Your Ad Is Displayed`](/metrics/google-ads-impressions) ## Customer stories ## Learn how teams ship analytics faster Organizations that scaled analytics without scaling headcount [All case studies →](/blog/success-stories) [Pürblack · "For 10 years I was blind."
