Don't Guess, Measure - Understanding Email Marketing Effectiveness

But have you ever wondered how to measure the success of your email marketing campaigns? Even if you think you know how your emails are performing, it's hard to tell what's really working—and what could use a little bit of improvement. That is why understanding and tracking email marketing effectiveness is so important.

With the right data and insights, you can evaluate your email campaigns' performance, identify opportunities for optimization, and design better plans for reaching potential customers. To make sure you're making the most out of your efforts, it pays to have a solid plan in place for measuring your email marketing effectiveness. In this article, we'll cover why it matters and how you can get started.

What are Email Metrics?

Email metrics are a set of data points that can provide you with valuable insight about your email campaigns. This data can help you figure out which aspects of your emails are working—or not working—so you can make informed decisions about how to improve them. Some of the important email metrics to consider include open rates, click rates, unsubscribe rates, conversion rates, and time spent engaging with emails.

Measuring Open Rate Success

How do you measure open rate success? Well, tracking the open rate of each campaign gives you an indication of whether or not your audience is interested in what you have to say. A higher open rate means more people are receiving and engaging with your message, while a lower rate could signal a need to adjust your content or send times.

Open rates are typically measured as the percentage of emails that were opened out of those that were sent. To accurately measure this metric, consider using a third-party service like MailChimp to track click-throughs and identify which emails have been viewed by recipients. This can provide valuable insights into which subjects and offers performed best for any given campaign.

Tracking Tap-Throughs and Click-Throughs

When someone taps or clicks a link in your email, it's counted as a tap-through or click-through. This gives you an idea of how many people actually interacted with your email, which is a great metric to measure the effectiveness of your email campaigns.

Here are some other metrics you can track once someone has clicked through:

  • Page views - How many pages has the customer viewed?

  • Time spent on page - How much time is spent on each page?

  • Unique page views - How many different pages were viewed?

  • Product views - What products are being viewed?

  • Conversion rate - How many visits lead to purchases?

  • Form completions - Are people completing contact forms or signing up for newsletters?

  • Repeat visits - Have customers returned over time, or visited more than once in a certain timeframe?

Using a/B Testing

Here's how it works: You create two versions of an email (A and B), each featuring different elements, such as design, subject line, call-to-action, content and more. Then you A/B test them by sending them out to a segment of your mailing list and measuring the results according to your defined metrics.

Ultimately, A/B testing allows you to make data-driven decisions about which emails are successful and use those findings for future campaigns. With this tool in your arsenal, measuring email marketing effectiveness has never been easier!

Measuring ROI for Email Campaigns

Here are a few factors to consider when measuring your email marketing ROI:

Conversion Rate

The conversion rate measures how many customers took action after seeing an email campaign. It's important to track whether customers click on links, make purchases or take other desired actions—such as signing up for a newsletter—as these actions indicate conversions.

Lifetime Value

Customer lifetime value (CLV) refers to how much money a customer spends over their "lifetime" as an engaged customer of your brand. CLV considers the repeat purchases customers make over time and helps you understand which campaigns are driving loyalty and long-term engagement. This can be measured by looking at average order size, purchase frequency, and customer retention rates.

Cost Per Acquisition (CPA)

Cost per acquisition (CPA) is a metric that shows you how much each new customer acquisition costs in terms of marketing expenses, such as ad spend, lead generation costs and discounts offered during campaigns. By calculating CPA after each campaign launch, you can determine whether certain marketing activities have better ROI than others over time.


Analytics can help you level up your email marketing game but remember: technological solutions are only as good as the data that's behind them. Measurement is essential, but so is having a deep understanding of customer needs, preferences, and behaviors. With that understanding, you can create actionable insights and accurate user data to measure the success of your email campaigns.
