Every brand wants to have a successful email marketing campaign with a high conversion rate. However, this is easier said than done – if you want to achieve success with your email marketing, then you have to be strategic about how you develop your campaign. A big component of effective email marketing is evaluation – where you measure the outcomes of your campaign. In order to allow yourself sufficient time to adapt to your business environment, it’s important to keep evaluating your campaign on an ongoing basis, at various stages of the campaign.
Launching a high conversion email campaign requires collecting data and making strategic marketing decisions.
Measuring KPIs is essential to keep track of your email campaign’s overall health. Also, it can help you measure your progress over time, better understand which email pieces work best, and make adjustments accordingly.
Not particularly sure which KPIs to monitor? No worries! We’ve gathered the top 12 KPIs you should follow to launch a successful high converting email marketing campaign.
1. Delivery rate
The delivery rate refers to the percentage of emails that have reached your recipients’ inboxes.
Even though having an extensive email list is always a plus, it doesn’t necessarily mean that all of your subscribers will get to see the emails you’ve sent.
While you want to ensure the majority of your list receives your emails, you simply can’t aim for a 100% delivery rate. Here are some reasons why:
- Many users change or delete their email addresses (e.g., after leaving work or graduating from school).
- You have a low sender reputation score. This happens when you choose spammy words.
- Your emails land in the junk or spam folder. This typically happens either because you used spam-trigger words in your email copy or due to an email service provider.
Even though you can’t deliver 100% of emails, ensure you have a strategy to increase the delivery rate.
How to calculate delivery rate?
Delivery Rate = (Number of Emails Sent – Number of Bounces) ÷ Number of Emails Sent × 100
2. Open rate
Open rate refers to the number of opened emails for a particular marketing campaign.
Email open is one of the most essential and fundamental email marketing KPIs. It shows you how many people are interested in opening and reading your emails.
The open rate is applicable as a comparative metric. For example, you can compare your open rates of discount offers emails with regular promotional emails. This will give insight into which emails seem more valuable to your subscribers. As a result, you can craft more targeted and personalized copies to help your conversions.
How to calculate the open rate?
Open rate = Number of Emails Opened ÷ (Number of Emails Sent – Number of Bounces)
3. Open rate by device
Open rate by the device is a KPI that shows you which devices your subscribers use to view your emails.
Knowing whether your recipients open emails on their laptops, smartphones, or tablets is crucial as it allows you to design effective email campaigns.
Studies suggest that mobile opens account for 46% of all email opens. This number highlights the importance of mobile experiences and responsive design. If you want to increase your email conversions, ensuring all of your emails are responsive and can be opened on all devices is a fundamental step to take.
Keeping track of the open rate by the device will help you design your emails strategically concerning user experiences.
How to calculate the open rate by device?
While there is no single formula to calculate open rate by device, you can use email tracking software that automatically measures the rate.
4. Click-through rate
Click-through rate (CTR) represents the ratio of recipients who click on a specific link within your email.
Your CTR is typically determined by the content of your emails, such as images, videos, text, and (especially) call-to-actions.
CTR is one of the fundamental email marketing KPIs that allows you to track the performance of each email piece individually.
To improve your CTR, carry out regular A/B testing on wording, visuals, style, and CTAs. Compare the results of your A/B testing efforts to determine which email elements cause recipients to convert.
How to calculate CTR?
CTR = (Total Email Clicks ÷ Total Emails Delivered) × 100
5. Click-to-open rate
Click-to-open rate (CTOR) is a KPI that compares the number of recipients who opened your email to the number that clicked a particular link within your email.
CTOR helps you to measure how many of those who opened your email got interested in reading the copy and acted on the CTA.
The click-to-open rate also helps identify how well your subject line works with your email copy. According to experts from popular marketing companies, when you see that your subject line generates a lot of opens, but there are not many clicks happening, you may consider improving your content pieces and CTAs.
How to calculate CTOR?
CTOR = (Number of Unique Clicks ÷ Number of Unique Opens) × 100
6. Unsubscribe rate
Unsubscribe rate refers to the percentage of subscribers who opt-out from your email list.
As another fundamental email marketing KPI, the unsubscribe rate identifies possible areas for improvement.
Keeping track of the unsubscribe rate is especially important when you A/B test new elements or change your email marketing campaign. In some cases, the unsubscribe rate identifies that subscribers are not interested in receiving your emails but don’t view them as spam.
How to calculate unsubscribe rate?
Unsubscribe rate = (Total Number of Unsubscribes ÷ Total Number of Emails Delivered) × 100
7. Bounce rate
Bounce rate represents the percentage of recipients who didn’t receive your email because a mail server returned it.
You should track two types of bounces – hard bounces and soft bounces. Hard bounces are permanent, while soft bounces are temporary. Hard bounces are typically caused by invalid, non-existent, or closed email addresses. Soft bounces usually occur due to some issue on the receiving end.
Measuring bounce rates can help you ensure there are no issues with subscribers receiving your emails. Also, if the numbers identify too many hard bounces, you may reconsider the email’s wording.
How to calculate bounce rate?
Bounce Rate = (Total Number of Bounced Emails ÷ Total Number of Emails Delivered) × 100
8. Email forwarding rate
Email forwarding rate refers to the percentage of subscribers who forwarded your email to others.
The email forwarding rate might now seem like an essential KPI at first, but it’s crucial to identify how you generate new contacts.
Encourage your subscribers to pass along your message. This way, you will acquire new recipients in your email list and thus increase the conversion rate.
How to calculate the email forwarding rate?
Email Forwarding Rate = (100 Clicks on Share / Forward Button ÷ 10,000 Total Delivered Emails) × 100
9. Spam complaint rate
The spam complaint rate implies the percentage of subscribers who marked your email as spam.
While this KPI is one of the most underrated, it can give you a better idea of your email performance.
Keep track of the spam complaint rate when you change or A/B test any email elements. This way, you’ll know which emails perform better than others and can be used to increase conversions.
How to calculate spam complaint rate?
Spam Complaint Rate = (Spam Complaints Received from Users ÷ Total Delivered
10. List growth rate
The list growth rate is a KPI used to track how fast your email list grows.
The list growth rate is critical because it allows you to measure your email marketing performance in the long run.
You’ll be surprised to discover that the email list growth rate tends to decay over time. Studies show that email marketing databases naturally degrade by 22.5% every year. That’s why you want to focus on growing your email list and improving your email content to keep users from unsubscribing.
How to calculate the list growth rate?
List Growth Rate = ((Number of New Subscribers – Number of Unsubscribers + Email/Spam Complaints) ÷ Total Number of Subscribers) × 100
11. Return on investment
Return on investment (ROI) is another fundamental email marketing KPI that tells you the total return on investment for your email marketing campaigns.
ROI helps evaluate the effectiveness of investment and understand how your email efforts translate into actual revenue.
How to calculate ROI?
ROI = ((Total Amount Gained from Email Efforts – Total Amount Spent on Email Efforts) ÷ Total Amount Spent on Email Efforts) × 100

12. Conversion rate
The Conversion rate is the final key performance indicator closing our list.
Conversion rate refers to the percentage of email recipients who complete the desired action (a conversion).
A conversion can vary from one email campaign to another but typically implies filling out a form, creating an account, or purchasing.
A high conversion rate indicates the success of your email marketing campaign. It means that your email efforts resonate with the needs of your target audience members as they’re willing to convert into paying customers.
If you want to improve your email conversion rate, use the mentioned KPIs strategically to craft your email campaign. Compare key performance indicators to identify which email pieces work better than otters and which cause more users to convert.
How to calculate conversion rate?
Conversion Rate = (Total Number of Conversions* ÷ Total Number of Delivered Emails) × 100
*Number of users who completed the desired action
