Understanding Email Marketing ROI
Email marketing remains one of the most effective digital marketing channels, often delivering an average return of $36 for every $1 spent. However, calculating your specific Email Marketing ROI is crucial for justifying budget increases and optimizing campaign performance.
The Core Formula
To calculate ROI, we use the standard formula adjusted for marketing spend:
ROI = [(Total Revenue – Total Cost) / Total Cost] x 100
Key Metrics to Track
Open Rate: Percentage of recipients who opened the email. Low open rates usually indicate poor subject lines or deliverability issues.
Click-Through Rate (CTR): The percentage of openers who clicked a link. This measures the relevance of your content and CTA.
Conversion Rate: The percentage of people who clicked and then completed a purchase or goal.
Average Order Value (AOV): The average dollar amount spent each time a customer completes a transaction via your email.
Example Calculation
Imagine you run a promotional campaign for a boutique store:
Cost: $200 (Software + Design)
Emails Sent: 5,000
Open Rate: 20% (1,000 Opens)
CTR: 5% (50 Clicks)
Conversion Rate: 10% (5 Sales)
AOV: $100
In this scenario, your Total Revenue would be $500. Your Net Profit would be $300 ($500 – $200 cost). Your ROI would be 150%.
How to Improve Your Results
If your calculator results aren't where you want them, focus on three areas: List Hygiene (to improve open rates), Personalization (to improve click rates), and Landing Page Optimization (to improve conversion rates). Even a 0.5% increase in conversion rate can significantly shift your ROI into the green.
