1. Open Rate

The open rate measures the percentage of recipients who opened your email. It indicates the effectiveness of your subject line, sender name, and preheader text in capturing the attention of your audience. A higher open rate suggests that your emails are resonating with your subscribers. 

Let’s say you run an e-commerce store and send a promotional email offering a 20% discount on selected products. By tracking the open rate, you can determine how engaging your subject line is. If you achieved a 40% open rate, it indicates that your subject line was effective in piquing the interest of your subscribers.

2. Click-through Rate (CTR)

The click-through rate measures the percentage of recipients who clicked on a link within your email. It shows the effectiveness of your content, design, and call-to-action in enticing recipients to take action. A higher CTR indicates that your email content resonates with your audience and encourages them to engage further.

Suppose you send an email with a compelling call-to-action button to encourage subscribers to visit your website and make a purchase. If you have 500 clicks from 1,000 opened emails, your CTR would be 50%. This metric demonstrates the level of interest and engagement your email generated.

3. Conversion Rate

The conversion rate measures the percentage of recipients who completed a desired action after clicking on a link in your email. This action could be making a purchase, filling out a form, downloading a resource, or any other predefined goal. Tracking the conversion rate allows you to assess the effectiveness of your email in driving meaningful outcomes for your business.

Suppose your email campaign aimed to promote a webinar and you had 50 registrations from 500 clicks. Your conversion rate would be 10%. This metric shows the impact of your email marketing success in achieving your specific goals. Read a step by step guide to start email marketing

4. Bounce Rate

The bounce rate indicates the percentage of emails that were not delivered to recipients’ inboxes. Bounces can be categorized into two types: hard bounces (permanent delivery failures due to invalid email addresses) and soft bounces (temporary delivery failures, such as full mailboxes or server issues). Monitoring the bounce rate helps you maintain a clean and up-to-date email list, leading to improved deliverability and engagement.

If you sent 1,000 emails and received 50 hard bounces and 30 soft bounces, your bounce rate would be (50 + 30) / 1000 = 8%. This metric highlights the quality of your email list and identifies potential issues that may impact your deliverability.

5. Unsubscribe Rate

The unsubscribe rate represents the percentage of subscribers who opt out of receiving future emails from your campaign. It’s crucial to track this metric to understand if your content, frequency, or targeting is not meeting subscribers’ expectations. A high unsubscribe rate may indicate a need for improvements in your email strategy.

If you had 20 unsubscribes from 1,000 delivered emails, your unsubscribe rate would be 2%. This metric helps you evaluate the effectiveness of your email content and identify areas for optimization.

6. Click-to-Open Rate (CTOR)

The click-to-open rate measures the percentage of unique clicks per unique opens. It provides insights into how engaging and relevant your email content is to your recipients after they open it. A higher CTOR indicates that your content resonates with your audience and motivates them to take action.

If your email received 500 unique opens and 200 unique clicks, your CTOR would be (200/500) * 100 = 40%. This metric helps you understand the effectiveness of your email content in driving engagement.

7. List Growth Rate

The list growth rate measures the rate at which your email subscriber list is expanding. It reflects the effectiveness of your lead generation and audience acquisition strategies. By tracking this metric, you can assess the success of your efforts to attract and engage new subscribers.

Suppose you started the month with 1,000 subscribers and gained an additional 200 subscribers throughout the month. Your list growth rate would be (200/1,000) * 100 = 20%. This metric helps you evaluate the effectiveness of your lead generation campaigns.

8. Email Forwarding Rate

The email forwarding rate measures the percentage of recipients who forward your email to others. It indicates the level of interest and value your content provides, as well as the potential for expanding your reach through viral sharing. Tracking this metric helps you understand the effectiveness of your email content in encouraging recipients to share it with their networks.

If your email was forwarded by 30 recipients out of 500 total recipients, your forwarding rate would be (30/500) * 100 = 6%. This metric highlights the share ability and potential reach of your email campaigns.


Measuring the success of your email marketing campaigns is vital for understanding their impact and making data-driven improvements. By tracking key metrics like open rate, click-through rate, conversion rate, bounce rate, and unsubscribe rate, you can gain valuable insights into the performance of your campaigns. Remember, these metrics should be analyzed in combination with each other to paint a comprehensive picture of your email marketing success. Continuously monitoring and optimizing your email campaigns based on these metrics will help you achieve better results and maximize the ROI of your email marketing efforts.
