Short For What

Measuring the success of your email campaigns using key performance indicators can provide valuable insights. Essential Key performance indicators reveal how effectively certain aspects of an email marketing campaign are. In most cases, you’ll want to track who opens your marketing emails and who forwards them to their contacts. Nonetheless, these indicators won’t prove your plan’s worth unless used in conjunction with others.

Tracking subscriber behavior can help you evaluate a campaign’s success and make course corrections as needed. Metrics such as unsubscribe, click-through, and bounce rates may swiftly reveal whether a campaign isn’t producing the anticipated results.

Email Marketing Key Performance Indicators

The primary indicators of success should be open rates, click-through rates, and unsubscribe rates. An early Key Performance Indicator to consider is opening rates.

The percentage of recipients who open an email may indicate the message’s or campaign’s success. If the recipients care about the subject matter, they will be more inclined to open your emails. However, this is not always indicative of the successful implementation of your strategy. Subject line open rates are a poor indicator of the quality of your content overall.

Click-through rates are an indication of how involved your audience : If you want to create a useful metric of success, you also need to keep track of the amount of attention you’re getting. If your call to action succeeds in getting a subscriber to click on it, you’ll know you’ve done a good job of outlining the specifics of your products or services. The percentage of clicks to the website’s actual content will show this.

  • Click-through rates of 15% are acceptable.
  • Early warning is provided via unsubscribe fees.

You may learn more about your areas of improvement by analyzing your unsubscribe rates. If people are constantly bombarded with defective goods, they won’t stick around for long. If you notice a rise in unsubscribe rates, you may want to reevaluate your whole strategy.

Is It So Crucial

You can’t improve your strategy until you track how quickly people absorb your content. While most marketers have a bird’s-eye view, keeping tabs on each component to pick up on even slight shifts in customer behavior is important.

According to some estimates, companies may get back $38 for every $1 they spend on email marketing. To earn such a profit, you must keep up with the most recent developments in customer preferences.

By implementing surveys and other feedback tools for your products and services, you may keep an ear to the ground for any negative customer comments. However, this does not necessarily reflect how clients react to your messaging. Analytics and key performance indicators can provide insights that regular feedback cannot (like your customer retention rates).

If your email campaigns aren’t reaching many people, it may be time to clean out your subscriber lists. You may also try improving your call to action and content strategy if you have a low conversion rate. Likewise, if your unsubscribe rates are steadily climbing, you may need to rethink your approach.

All your marketing efforts, in terms of individual campaigns and the overarching plan, should benefit from each new piece of information you gain. Keeping note of your most successful campaigns will allow you to use what you’ve learned in the future. Far too many marketers are just keeping an eye on 3-5 key performance indicators that should be monitored to obtain the whole picture.

Consideration #1: The Number Of Emails Sent

Even if you have 10 or 100, or a thousand people on your email list, your messages may not get delivered. This is because a perfect deliverability rate just cannot be achieved. If your inbox only reads 85% of your emails, for example, the other 15% might as well not exist. You have a problem if you sent an email to 1,000 people and 150 didn’t receive it. Second, you need to be alert for sudden decreases in deliverability.

When using a shared IP address instead of a dedicated one, marketers risk being unexpectedly banned by an ISP. If for some reason, you suddenly can’t send an email to a person using a Gmail account, for instance, you need to investigate the root of the problem immediately.

Just a heads up: even if an email says it was “sent,” it could not make it to the inbox. You risk sending it and having the addressee throw it away. The Inbox Placement Rate is a key performance indicator that many marketers are starting to use to monitor how many emails get delivered to the inbox. The percentage of sent emails that are read comes in at a close second.

Being Delivered To The Inbox Is Not Enough

It’s also important to monitor how often messages are opened. You might have a 79% open rate and get 85% of your emails, but it doesn’t mean your audience is paying attention. This is why keeping an eye on the open rate is essential.

Maintaining a high level of deliverability requires constant attention to open rate trends and the implementation of any necessary corrections. Opening rates can be compared to industry averages to provide a basis for comparison. Suppose you’re going to make a comparison. In that case, it’s important to compare apples to apples rather than using a generic standard (which makes sense, given that individuals are likely to receive emails from their banks and the hotels they frequently stay at).

Bear in mind that certain users may make use of email preview windows. This can keep track of phantom email opens. Moreover, text-only emails will not be counted as open even if they are opened.

The Average Percentage Of Clicks

How many of your email’s readers took action and clicked on a link may be gauged by the CTR. Openings and deliverability are important, but there is more to consider. Not only do you need to know which links caught their interest throughout each campaign, but you also need to know exactly where those links were located.

If, for example, the vast majority of clicks occurred above the fold, you would have passed the blink test. Adjust your text CTA as necessary; for instance, if you supplied the same link twice with a different language and found that one performed better than the other. Also, try using text links instead of buttons. Record which of your links were opened by the intended recipients. The fact that the unsubscribe link might also be counted as a click is NOT GOOD!

The Ratio Of Clicks To Impressions

How many of the people who viewed your email followed the link within it? The CTO rate is determined by dividing the number of openings by the number of click-throughs. This rating shows how well your subject line and content complement one another.

Something was off if your email’s subject line garnered numerous opens but few clicks. If you had a lot of clicks but not many opens, it means you had a great offer but a weak subject line. Your open rate might be affected by factors beyond the subject line, such as the quality of your list, the sender’s email address, the time of day you send, etc.

The Cancellation Fraction

This key performance indicator is something you really must implement. What percentage of subscribers are dropping off can tell you a lot. Instead of reporting your messages as spam, it may indicate that people just stopped reading them and mistakenly added them to the wrong list.

Monitor your unsubscribe rate after implementing major changes, such as segmentation, a template redesign, or a new mailing schedule. If an increase in cancellations is noticed after making the change, you may want to reconsider. Your deliverability will improve over time if you remember that people who unsubscribe are doing so voluntarily and because they no longer wish to receive your messages.

The Rate Of Return: Hard And Soft

A moderate bounce won’t do much, but a substantial one can change the course of your life. The majority of times, hard bounces are caused by invalid email addresses. This happens when an employee leaves their job, deletes their email address, or enters an incorrect email address (ex: with a typo). You should pay attention to hard bounces since they indicate that you haven’t kept up with list cleansing.

It may also imply that you must verify the email addresses you provide using a double opt-in or another method. Hard-bounced email addresses are useless and should be removed from your list immediately. However, gentle bounces only last briefly and are caused by issues on the other end. A packed email or a malfunctioning server might be at blame. No matter your email marketing platform or email service, the system will only attempt to resend the message a few times.

Spam-Related Complaints

You should monitor spam complaints alongside your unsubscribes since some customers prefer to report emails as spam rather than unsubscribe. Something is amiss if two key performance indicators are converging. If you make a change, you should monitor this value as well.

Mentions In Online Publications

This key performance indicator evaluates engagement on social media and is an accurate reflection of your content’s worth. So, it might be helpful to make it easy for readers to share your content by incorporating social sharing buttons in your emails. One of the email blogs I subscribe to makes it so tough to forward its great content that it borders on being humorous.

The only link in the whole email will take you back to their homepage, where you will have to navigate many levels of menus before reaching their blog. And to make matters even more confusing, they email it to subscribers days before posting it on the site. So, if I want to spread the word, I’ll have to set a reminder to see whether they’ve uploaded it on their site in a few days.

Go Onwards

This key performance indicator is comparable to social shares. One key difference is that people who get content via email are more likely to interact with it than those who see the same content on social media marketing.

This is because forwarding functions as much as picking up the phone or receiving a physical letter. Its unusualness makes it a focal point. This is another indicator of your content’s interest and shareable, which you should strive to improve.


The most important metric is conversions. Despite the implication, I don’t think we’re talking about currency here. Based on your campaign’s goals, a conversion may be a purchase, subscription signup, demo registration, content download, or something else entirely.

Your email marketing campaigns may have several goals. Understanding why you’re measuring is as important as knowing what you’re measuring when monitoring conversions. It would help if you immediately kept an eye on these metrics in email marketing.

You may start testing to optimize your campaigns now that you know the ten most significant key performance indicators for email marketing. This might help you establish new goals unrelated to conversions, such as increasing your subscription rate or decreasing spam complaints.
