Needless to say, marketers can achieve phenomenal success by monitoring the relevant email metrics. Here are some of the top benefits of tracking email marketing metrics and how they help you accomplish great results.

1. Save Time

Ideally, email marketing campaigns aim to send a series of emails to inform, capture and nurture leads.

But if your audience has not even opened the first email you sent, the chances of them opening and reading the follow-up emails are very rare.

With the help of email tracking, you can monitor the open rate of your first set of emails to assess the response of your readers. By understanding how the readers are engaging with your emails, you can decide on the kind of follow-up emails you need to send.

This prevents you from flooding the audience with unnecessary emails and wasting their time and yours.

2. Provide Context for Your Future Campaigns

Email marketing is a powerful medium to interact with your connections, followers, and prospects. And to make every interaction interesting and fruitful, you should create powerful email marketing campaigns.

Measuring email marketing metrics will provide you with the right context and frame of reference for your marketing team. It creates a detailed data-driven backdrop that can precisely tell you what works with your audience and what doesn't.

You can find keywords, graphics, and videos that best resonated with your audience and reuse them in future campaigns too.

3. Help Measure the Effectiveness of Your Email Content

When setting certain goals for your email marketing campaign, the content has to be prepared accordingly.

The subject lines should be catchy enough to pique the curiosity of the readers and the body of the email should have the right balance of text, graphics, and promo videos to encourage them to take action.

Email marketing metrics like open rate, click-through rate, website visits, and so on indicate how effective your content has been in compelling the email recipients to take action.

4. Provide Insight Into Customer Engagement

As an email marketer, your aim is to ensure quality customer engagement to grow your business, and the only way to measure it is to track the right email marketing metrics.

By analyzing multiple email metrics, you will be able to understand how well the recipients are responding to your emails.

Right from welcome emails to recommendations, and lead magnets, you can track a variety of emails to gather specific data that throws light on your customers’ interests, preferences, and pain points.

This customer engagement analysis will help you streamline your email marketing efforts and create tailored email campaigns.

5. Help Determine the Right Email Frequency

Sure, emails can help you drive sales and other great results.

But when and how many emails should you send to ensure maximum engagement?

Email marketing metrics may hold the right answer to this question.

According to Campaign Monitor’s Email Marketing Benchmarks Report, Monday has the highest open rates whereas the unsubscribe rates are the lowest on Saturday and Sunday.

But this too may not hold true for you.

It’s essential to monitor your email metrics well to figure out the days and times when your emails are likely to make the most impact. And once you hit the right frequency, you can nurture your audience with relevant content.

6. Help Track Campaign Performance in Real-Time

One of the top advantages of tracking email marketing metrics is that it helps you monitor the performance of your email campaign in real-time.

With the help of a capable email marketing tool, you can track the open rate, click-through rate, bounce rate, conversion rate, and several other metrics in real time and analyze the data.

This can be highly beneficial in assessing the overall performance of the email campaign at every stage and modifying it on the go can help drive better results.

7. Help You Stay Focused on the Goals

Your email marketing KPIs serve as the point of reference for email marketers to stay focused on the goals you want to achieve.

While you rely on certain general metrics to track the success of an email campaign, you can opt to monitor a few other specific email metrics based on the goals you set.

It is only by tracking such metrics that you can successfully determine where you stand. Based on these email metrics, you can design your email marketing campaigns and target them toward the right audience.

Without the right KPIs, the chances of swaying away from the desired goals are quite high.

12 Key Email Marketing Metrics You Should Track

Now that you know the benefits of tracking email marketing metrics, let’s take a look at the top 12 metrics every email marketer should track in 2022 and beyond.

1. Open Rate

Open rate is one of the most important email marketing metrics you should be monitoring. It refers to the ratio between the total number of emails sent and the number of emails opened.

Email open rate can help you understand how effective your email subject lines are and how many of your subscribers are keen to open your brand’s email.

This email marketing metric can be used as a comparative key performance indicator to check the week-on-week performance of your campaign.

2. Click-Through Rate (CTR)

CTR is one of the most critical email metrics for email marketers. It tells you how many email recipients clicked on a link you provided in an email. These could be your social media links, affiliate marketing links, special offers, product links, or links to free resources.

This email marketing metric can help you track the performance of each email you send. As the click on the CTA is usually an important goal of any email campaign, your CTR is a metric that you must track.

Remember, click-through rates are typically much lower than open rates. To improve this important metric, you need to deliver what your subject line promised, improve list segmentation, and write compelling CTAs. The CTA design and placing also matters equally.

3. Conversion Rate

Needless to say, the conversion rate of any email campaign is absolutely critical as it gives you an idea of where your campaign stands in comparison to your goals.

It measures the percentage of people who completed the desired action against the total number of delivered emails.

Conversion rate shows how successfully the email CTAs were able to achieve the overall email marketing goals you had set.

Let’s say you have sent an email to promote an ebook. So when the reader actually downloads the ebook, it is considered a conversion.

This metric gives a clear perspective of how successful your email marketing strategy was in generating and nurturing leads.

4. Bounce Rate

When you execute an email marketing campaign, you not only want to know how many emails were delivered but also how many email addresses didn't receive your email.

This metric can be further categorized into soft bounces, referring to temporary issues) and hard bounces, meaning permanent issues with email addresses.

These email addresses could be fake, old, or may contain errors. Bounce rate can give you a clear idea about the quality of your subscriber list.

Simple measures like double opt-in which requires the users to verify their email address can help you reduce the bounce rate and boost the quality of your list. Regularly trimming your email list helps too.

5. Spam Complaint Rate

It's quite depressing to see your emails getting marked as spam by the recipients but tracking such email marketing metrics is important in enhancing the effectiveness of your email marketing campaign.

This metric should not be ignored because if your spam complaint rate is high, email service providers may take action against you as part of their customer service policy. This may impact your deliverability.

6. Email List Growth Rate

Attracting new subscribers is one of the major goals of email marketing and that’s why it’s critical to track this email marketing metric.

When you compare the number of new subscribers with the number of unsubscribes, bounces, and manual removals, you will get a clear picture of your reach.

Based on the insight, you can tweak your approach to expand your reach and garner more subscribers for your email campaigns.

7. Domain Open Rate

Domain open rate shows you the percentage of receivers opening your email for each email service provider. Due to this segmentation among subscribers, it’s an important email marketing metric.

And why is that?

By measuring domain open rate you can identify domain-specific problems and modify your email content to avoid spam filters. For instance, if there’s a sudden drop in domain open rate, it could signify some issues that may need your attention.

This metric may not yield accurate data when it comes to Apple mail users who have opted for MPP, but it can be tracked successfully for any other email provider.

8. Device Usage Rate

To understand which device your subscribers are using to access your emails, it’s important to measure this email marketing metric. You should know whether a majority of them are using a laptop, mobile phone, or tablet to read your emails.

Why does it matter?

Because the email content is displayed in a slightly different way on mobile devices than on a laptop. With the help of this important metric, you can optimize your email content for the devices most of your subscribers are using.

You can go a step further and check the open rate and click-through rate for each device and gain a better understanding of your audience’s behavior.

9. Revenue Per Email (RPE)

With every email marketing campaign you run, you want to measure the ROI. Revenue per email is a vital email marketing metric that allows you to track the precise monetary value of every email you send.

It gives you a clear insight into the effectiveness of your email subject line, content, offers, and CTAs, and how well they are resonating with your audience.

By understanding which emails are driving better revenues for your brand, you can optimize your email marketing efforts.

10. Subscriber Acquisition Cost (SAC)

As discussed above, with every email campaign, you need to quantify how many new subscribers you acquired, and calculating SAC will tell how much it cost you to gain these new subscribers.

This is a critical email marketing metric to measure as it can help you calculate your ROI more accurately and plan more targeted campaigns in the future.

To reduce SAC, you need to understand your audience’s interests and pain points and invest in more valuable lead magnets.

11. Subscriber Lifetime Value (LTV)

This email marketing metric measures the value a subscriber provides your business throughout the lifetime they spend with you. Essentially, you’d have to calculate all the purchases made by the subscribers to get to this metric.

You can calculate this metric for months, weeks, or years depending on the average subscriber’s lifecycle.

By comparing LTV with subscriber acquisition cost, you can assess whether the cost of acquiring a subscriber is justified or not.

12. Email Forward and Share Rate

When your subscribers find your email content exciting or useful enough, they tend to forward or share it with their friends.

This could be in the form of clicking the ”share it” button to share the content on Facebook, Twitter, or Instagram. They could even forward the email to their friends.

Your email tracking software can track such actions and provide you with valuable insights based on it.

This is a very important metric to track if you are a B2C business. These users act as your brand advocates to influence the buying decisions of their connections so the higher this value is, the better it is for you.
