15 Essential Email Marketing KPIs to Track

To measure the success of email marketing campaigns, businesses should track a range of KPIs.

Here are 15 essential email marketing KPIs to track in 2023:

Click-Through Rate (CTR)

The click-through rate measures the percentage of recipients who click on one or more links within an email. It indicates how well the email content resonates with the audience and how effective the calls to action are.

To increase the click-through rate, businesses should make their content and links within emails more compelling. Clear calls to action, prominent buttons, and valuable content can all contribute to a higher CTR.

Delivery Rate

The delivery rate measures the percentage of emails that successfully reach subscribers’ inboxes. A high delivery rate indicates that emails are effectively getting past spam filters and reaching the intended recipients.

To improve delivery rates, businesses should regularly clean their email lists and remove inactive or invalid email addresses.
Maintaining a good sender reputation is also crucial for achieving a high delivery rate.

Open Rate

The open rate is the percentage of recipients who open an email out of the total number of emails delivered. It reflects the effectiveness of subject lines and provides insights into how well recipients are engaging with the content.

To improve open rates, businesses should craft compelling and personalized subject lines. Experimenting with sending times can also help determine when recipients are most likely to open emails.

Unsubscribe Rate

The unsubscribe rate measures the percentage of subscribers who choose to unsubscribe from an email list within a specific time frame.
A high unsubscribe rate can indicate a disconnect between the content delivered and the subscribers’ interests.

To reduce the unsubscribe rate, businesses should regularly survey their subscribers to identify areas for improvement.
Testing different types of content, delivery times, and frequencies can also help determine what resonates best with subscribers.

Conversion Rate

The conversion rate measures the proportion of email recipients who complete a desired action, such as making a purchase or signing up for a webinar.

It is the ultimate measure of a campaign’s success in driving subscribers to take action.
To improve conversion rates, businesses should ensure that their email content is aligned with the call to action and that the landing page delivers on the promise made in the email.

List Growth Rate

The list growth rate measures how quickly an email list is expanding, taking into account new subscribers, unsubscribes, and spam complaints.

A positive list growth rate is essential for expanding the audience and offsetting natural attrition.
To grow the list, businesses should offer incentives for signing up, use multiple channels to promote the email list and make the sign-up process straightforward.

Bounce Rate

The bounce rate measures the percentage of sent emails that could not be delivered to the recipient’s inbox. High bounce rates can negatively impact the sender’s reputation and email deliverability.

To reduce bounce rates, businesses should regularly clean their email lists, remove inactive subscribers, and use double opt-in methods to ensure valid email addresses.

Spam Complaint Rate

The spam complaint rate measures the percentage of recipients who mark emails as spam. High spam complaint rates can damage the sender’s reputation and email deliverability.

To reduce spam complaint rates, businesses should only send emails to people who have opted in to receive them.
Clearly communicate the type of information subscribers will receive and how frequently. Ensure that the content is worthwhile and relevant to the audience.

Email Sharing/Forwarding Rate

The email sharing/forwarding rate measures the percentage of recipients who share or forward an email to others. When subscribers share emails, it amplifies the reach and can lead to new subscribers.

To encourage email sharing, businesses should include simple share buttons in emails, produce quality content suitable for sharing, and consider providing rewards.

Subscriber Churn Rate

The subscriber churn rate measures the percentage of email subscribers who unsubscribe within a specific time frame.
High churn rates can indicate dissatisfaction with email content and limit list growth.

To reduce the subscriber churn rate, businesses should regularly survey subscribers to identify issues and areas for improvement.
Testing different types of content, delivery times, and frequencies can help determine what subscribers prefer.

Revenue per Email

Revenue per email measures the average revenue generated from each email sent. It helps determine the value of each email in terms of generating revenue.

To increase revenue per email, businesses should focus on improving email content to increase engagement and conversions.
Implementing a loyalty program can also encourage repeat purchases and drive revenue.

Revenue per Click

Revenue per click measures the average revenue generated each time a recipient clicks on a link in an email. It helps understand the value of each click and informs decisions about improving click-through rates.

To improve revenue per click, businesses should optimize landing pages to increase conversions. Testing different types of offers and calls to action can help determine what generates the most revenue.

Mobile Click-to-Open Rate

The mobile click-to-open rate measures the percentage of recipients who open an email on a mobile device and click on a link within the email.

With the rise of mobile device usage, optimizing emails for mobile viewing and interaction is crucial. To improve the mobile click-to-open rate, businesses should use responsive email designs, make calls to action easy to tap on a mobile screen, and ensure that landing pages are also mobile-friendly.

Hard Bounce Rate

The hard bounce rate measures the percentage of sent emails that are permanently undeliverable due to issues like invalid email addresses or non-existent domains.
A high hard bounce rate can damage the sender’s reputation and email deliverability.

To reduce the hard bounce rate, businesses should regularly clean their email lists, remove unengaged subscribers, and use a double opt-in process to ensure valid email addresses.

Email Read Rate

The email read rate measures the percentage of recipients who not only open an email but also spend significant time reading it.
A high email read rate indicates that the content is engaging and relevant to subscribers.

To improve the email read rate, businesses should write compelling content, use subheadings and bullet points to make emails easy to skim and keep the content concise.
