4 Email Metrics that Really Matter
Email Marketing
How are you measuring the success of your emails? Even if you optimize your campaign to the T (read: mobile-friendly, compelling copy, optimally placed CTA, etc.), the only way to know if you are achieving your goals is by identifying and analyzing the relevant data.
With a sea of data at your fingertips, it can be difficult to focus on the email metrics that impact your bottom line. In this blog, we’ll discuss what you should zero in on to achieve success with every campaign.
There will be times that an open is actually your end goal for a campaign. For example, you may be disseminating important company updates to clients and an open would be a significant metric to track to determine if your campaign was successful.
More often than not, though, your goals will be more complex and opens won’t tell the whole story. In fact, SmartInsights found that open rates wrongly predict success 53% of the time. Furthermore, Idealware points out that certain clients are blocking images by default, so some reads aren’t counting toward the open rate since the tracking pixel wasn’t triggered.
Since opens aren’t often a good indication of campaign performance, let’s take a look at four metrics that are.
Conversion rate is probably the most important metric to measure the success of your campaign though what you consider a conversion will differ depending on the goal of your email. If your goal is to get webinar registrants, the conversion rate would be the number of recipients that receive the email and sign up.
Do note: you’ll most likely need a third party like Google Analytics to track your conversion rate. ESPs can calculate opens and clicks, but to track more you’ll need to tag links in your email with Google Analytics. Then you can set campaign goals and calculate your conversion rate via Google Analytics.

Your subscriber retention rate is all of your unsubscribes and bounces rolled up into one percentage, which tells you two things: If your email was relevant to your subscribers and if you are sending to a healthy email list. You can calculate this rate by using the following formula: Number of subscribers – bounce backs – unsubscribes/ number of subscribers.
Why should you care about these two components? Healthy lists improve your overall email metrics and, in turn, your sender reputation and inbox placement. And relevancy drives engagement in email. In fact, Ascend2 reports relevancy to be the most effective tactic to achieve email marketing objectives:
Aim for a high retention rate (85% or higher) to make sure your subscribers are sticking around. Once you have a solid list, then you can use the next metric to measure and improve your content.
As we mentioned in the beginning of the blog, opens are just the tip of the iceberg when it comes to email data. “Email engagement” is what happens between an open and a click.
One powerful feature of our analytics software is that it can track how long a subscriber has an email open. This offers context to your email open rates, because you can know whether someone opened your email only to immediately hit delete, or if someone actually took the time to engage with your content. Here are the ‘thresholds’ we have set to categorize a read, skim or glance:
This insight is invaluable as it allows you to determine whether or not the components of your campaign captured your audience’s attention. In the example below, 75% of the audience that opened the email had it open for 8 seconds or more. It’s safe to say that the email was highly engaging.
In short, engagement metrics will paint a more detailed picture of why some campaigns were successful and why others weren’t. Once you have tracked your engagement metrics, it’s time to get a more granular look into what your subscribers email behaviors mean for your future mailing strategy.
While subscriber action rate does not have a simple formula like subscriber retention rate, this metric is about uncovering how your audience consumes your emails. For example, finding the optimal time/day to send to your audience. A simple way to track subscriber action rate is to look at the time of day or week that your emails are opened and clicked. GetResponse ran a study that analyzed 21 million emails sent in the US during Q1 2012 and observed that the peak of inbox activity was on Thursday. In fact, Thursday was the top day for all metrics: percentage sent, open rates and CTR. Check out the stats below.
Every audience is different, though, so be sure to test different days/times and other factors (like CTA copy and placement) to find out when your audience is most likely to engage with your emails based on of opens, clicks and conversions.
As a marketer, you could drown in the amount of email data available. That’s why it’s important to analyze the data that directly impacts your campaign goals and bottom line.
