Understanding Email Marketing ROI
Email marketing remains one of the most effective digital channels for generating revenue, often boasting a higher Return on Investment (ROI) than social media or paid search. However, to truly optimize your campaigns, you need to look beyond vanity metrics like open rates and understand the financial impact of your efforts.
How to Calculate Email ROI
The formula for calculating your Email Marketing ROI is straightforward but requires accurate data points regarding your funnel performance. The core calculation is:
ROI = (Total Revenue – Total Campaign Cost) / Total Campaign Cost * 100
This calculator breaks down the funnel into specific stages:
- Volume: The number of emails successfully delivered.
- Open Rate: Indicates subject line effectiveness.
- CTR (Click-Through Rate): Indicates content relevance and call-to-action clarity.
- Conversion Rate: Indicates the effectiveness of your landing page.
- AOV (Average Order Value): The revenue generated per conversion.
Improving Your Email Metrics
If your calculation shows a negative or low ROI, consider optimizing these key areas:
- To boost Open Rates: A/B test your subject lines and ensure your sender name is recognizable.
- To boost CTR: Use clear, button-based Calls to Action (CTAs) and segment your audience to ensure content relevance.
- To boost Conversions: Ensure message match between your email copy and the landing page, and optimize page load speed.
What is a Good Email Marketing ROI?
While benchmarks vary by industry, a study by the DMA suggests that email marketing can average an ROI of $42 for every $1 spent (4,200%). However, a healthy ROI for a specific campaign usually falls between 122% and 500% depending on your margins and overhead costs.
