Why Email ROI is the King of Marketing Metrics

For years, email marketing has consistently delivered the highest **Return on Investment (ROI)** of any digital marketing channel, with some studies citing returns as high as 40:1. Why? Unlike social media platforms where algorithms control your reach, your email list is an asset you own. It's a direct, personal line of communication to an audience that has explicitly asked to hear from you. Measuring the ROI of this powerful channel is essential for understanding its true value to your business.

Step 1: Identify Your Key Campaign Metrics

To calculate your ROI, you first need to track the performance of your email funnel. These are the essential numbers you'll need for any given campaign:

• Open Rate: The percentage of subscribers who opened your email. This measures the effectiveness of your subject line.
• Click-Through Rate (CTR): The percentage of people who opened your email AND then clicked a link inside. This measures the appeal of your offer and call-to-action.
• Conversion Rate: The percentage of people who clicked a link and then completed the desired action on your website (e.g., made a purchase). This measures the effectiveness of your landing page.
• Average Order Value (AOV): The average amount of money each converting customer spends.

Step 2: Calculate Your Total Campaign Cost

This is more than just the monthly fee for your email service provider (like Mailchimp or ConvertKit). A true cost calculation should also include the value of the time spent on the campaign. For example, if it took 2 hours to write and design the email, and your time is worth $50/hour, you should add $100 to your campaign cost for an accurate ROI figure.

Step 3: Calculate Your Email ROI Instantly

Once you have your metrics and costs, you can put them all together to find your profit and ROI. The math involves multiplying the percentages down the funnel to find your total revenue, then comparing that to your cost.
