Measuring Email Marketing ROI: Key Metrics and Analytics for Success

iOS 15

As a marketer, you will always want to know if your email campaigns are paying off. Knowing how to measure your email marketing ROI can help you analyze your email campaigns and make informed decisions to improve your results. In this blog post, we’ll discuss the metrics and analytics that you need to measure your email marketing ROI.

Open Rate

The open rate is the percentage of recipients who opened your email. Every email recipient has the chance to open and read your email. If your open rate is low, your email may not be reaching the recipient. To increase your open rate, you can try making your email subject line more compelling or optimize the time and frequency when you send your email.

Click-Through Rate (CTR)

The click-through rate is the percentage of recipients who clicked a link in your email. A high click-through rate indicates that the email recipient was sufficiently interested to take action. To improve your CTR, you can optimize your email copy and design to make it more visually appealing and persuasive or make sure you’re targeting the right recipients.

Conversion Rate

The conversion rate measures the percentage of recipients who took the desired action, such as making a purchase or filling out a form after clicking on the link in your email. The conversion rate is a critical metric as it is the most direct way to see if your email is driving business. To increase your conversion rate, you may need to re-think your email messaging, including your offer, design, and incentives.


The ROI measures the return on investment from your email campaign. ROI is not just about making sales but also factors in the cost of your campaign, including the cost of your email marketing software and other marketing costs. To calculate ROI, you can use a simple formula: ROI = (Revenue – Cost) / Cost. This metric can reveal the true impact of your email marketing campaigns.

Subscriber Engagement

Subscriber engagement measures the percentage of subscribers that are opening and clicking on emails over time. To increase overall engagement, you can optimize your email strategy to ensure your emails align with your subscribers’ needs, interests, and pain points. Continuously monitoring your subscriber engagement rate can help you understand how your email campaigns are driving engagement over time.


In conclusion, measuring and analyzing your email marketing ROI allows you to track your email campaign’s effectiveness, find areas for improvement, and demonstrate the value of your email marketing program to business owners or decision-makers. Understanding some of the primary metrics we covered in this post will help you take action to increase engagement, clicks, conversions, and ROI. Investing in email marketing analytics will help maximize your email marketing campaigns’ impact and deliver better returns on your investment.
