Email unsubscribe rate explained and tips to reduce it

Did you know the average email unsubscribe rate for some industries can reach up to 2% per campaign? While that number might seem small, over time it can lead to a significant loss of subscribers. If you’re running email campaigns for your e-commerce business and notice a higher-than-average email unsubscribe rate, it’s a red flag that could quietly hurt your brand.

When someone clicks that dreaded unsubscribe button, you're not only losing a potential sale, but also valuable engagement metrics that email service providers like Klaviyo and Yotpo use to determine your email deliverability. In this post, we'll break down everything you need to know about your email unsubscribe rate, why it matters, and - most importantly - how to lower it. No matter the platform you’re using for email campaigns or lead capture, understanding unsubscribe rates is key to maintaining a healthy, engaged list.

Let’s dive into the details and discover actionable strategies you can implement to protect your list from the unsubscribe button.

What is an email unsubscribe rate?

Your email unsubscribe rate is the percentage of subscribers who choose to leave your list after receiving one of your emails. Think of it like this: you send out an email campaign to 10,000 subscribers, and 100 of them click "unsubscribe" after opening it. Your unsubscribe rate would be 1%.

To put it simply, it’s the percentage of people who opt out of your email marketing list after receiving a message. The unsubscribe rate can give you insight into how well your email campaigns are performing. While occasional unsubscribes are normal, a rising email unsubscribe rate is usually a sign that something is off.

Let’s break it down with an example:

Imagine you send an email campaign to 5,000 subscribers. If 50 people unsubscribe, your unsubscribe rate would be calculated as:

  • Formula: Number of unsubscribes ÷ Number of delivered emails x 100
  • Example: (50 ÷ 5000) x 100 = 1%

While 1% might seem small, it can add up over time, especially if your campaigns aren't delivering value.

How to calculate unsubscribe rates

The unsubscribe rate is straightforward to calculate and most email platforms like Klaviyo and Yotpo do it for you automatically. But, it’s still helpful to understand the formula:

Unsubscribe rate = (Number of unsubscribes ÷ Number of emails delivered) x 100

For example, let’s say you sent an email to 1,000 people, and 15 of them unsubscribed. You would calculate it like this:

(15 ÷ 1000) x 100 = 1.5% unsubscribe rate

Want to see how this looks in Klaviyo or Yotpo? Both platforms will display this figure prominently in their campaign reports, giving you an easy snapshot of your email list health.

The importance of measuring email unsubscribe rate

Your email unsubscribe rate is like a report card for your email marketing efforts. But why is it so critical to track? 

  1. List hygiene: A clean, engaged email list is the lifeblood of any successful campaign. A higher email unsubscribe rate means you’re losing engaged subscribers, which can hurt your email reputation.
  2. Email deliverability: Platforms like Klaviyo and Yotpo factor your email unsubscribe rate into their deliverability algorithms. A high unsubscribe rate can result in more of your emails landing in the spam folder.
  3. Improved campaign effectiveness: If people are unsubscribing in large numbers, it could be a sign that your content isn’t resonating, your emails are coming too frequently, or you're targeting the wrong audience.

Monitoring and lowering your email unsubscribe rate is crucial to ensure you’re reaching the right people with the right message. The goal is to keep your list engaged, relevant, and healthy.

Benchmarking unsubscribe rates

What is a good unsubscribe rate for email?

So, what exactly is a “good” email unsubscribe rate? The answer depends on your industry, but a general rule of thumb is to aim for an unsubscribe rate below 0.5%. Anything above 0.5% is worth investigating, but unsubscribe rates by industry can vary. For example:

  • E-commerce: 0.1% - 0.3%
  • Financial Services: 0.2% - 0.4%
  • Non-profit: 0.1% - 0.3%

What is a bad unsubscribe rate for email?

A bad unsubscribe rate is anything above 1%, and in some cases, even above 0.5%. If you find your unsubscribe rate creeping up, it's a clear sign that you need to reassess your content, frequency, and targeting strategies. Consistently high unsubscribe rates can lead to lower deliverability and engagement rates, which will hurt your long-term growth.

Factors influencing unsubscribe rates

Several factors can impact your email unsubscribe rate. Understanding these can help you develop strategies to keep your subscribers engaged and reduce opt-outs.

Content quality and relevance

The quality and relevance of your email content play a crucial role in subscriber retention. High-quality, valuable content that addresses your audience's needs and interests is more likely to keep subscribers engaged. Irrelevant or low-quality content, on the other hand, can quickly lead to unsubscribes. Focus on creating informative, engaging, and personalized content that provides real value to your subscribers.

Frequency of emails/SMS

Finding the right balance in email frequency is crucial. Sending too many emails can overwhelm subscribers and lead to higher unsubscribe rates. Conversely, not sending enough can cause subscribers to forget about your brand. The optimal frequency varies depending on your industry and audience preferences. 

Consider implementing preference centers where subscribers can choose their desired email frequency, or use engagement data to determine the best sending cadence for different segments of your list.

Personalization and segmentation

Personalization and segmentation are powerful tools for reducing unsubscribe rates. By tailoring your content to specific subscriber groups based on their interests, behaviors, or demographics, you can significantly increase relevance and engagement. 

Platforms like Klaviyo offer advanced segmentation capabilities, allowing you to create highly targeted campaigns. Personalized emails that speak directly to a subscriber's needs and preferences are more likely to be appreciated and less likely to result in unsubscribes.

Clear call-to-actions (CTAs)

Clear and compelling call-to-actions (CTAs) are essential for guiding subscribers toward desired actions and maintaining engagement. On the other hand, vague or confusing CTAs can frustrate subscribers and lead to disengagement. 

Ensure your CTAs are clear, concise, and relevant to the email content. Use action-oriented language and make it obvious what you want the subscriber to do next. Well-crafted CTAs can improve click-through rates and overall engagement, reducing the likelihood of unsubscribes.

Optimal timing for sending

The timing of your email sends can significantly impact open rates, engagement, and ultimately, unsubscribe rates. Sending emails at the right time when your subscribers are most likely to engage can improve the chances of your content being seen and appreciated. 

Analyze your audience's behavior to determine the best times to send emails. Consider factors like time zones, work schedules, and industry norms. Tools like Yotpo can help you optimize your send times based on individual subscriber behavior, further reducing the risk of unsubscribes due to poor timing.

How to reduce your email unsubscribe rate

Reducing your email unsubscribe rate requires a strategic approach. Here are some effective tactics to help you keep your subscribers engaged and minimize opt-outs:

Analyze your email list and campaigns

Start by thoroughly analyzing your email list and past campaigns to identify patterns that might be leading to unsubscribes. Look for common characteristics among subscribers who tend to unsubscribe, such as acquisition source, engagement level, or demographic information. Review the performance of your past campaigns, paying attention to which types of content, subject lines, or sending times resulted in higher unsubscribe rates. Use tools like Klaviyo's analytics to gain deeper insights into your email performance and subscriber behavior. This analysis will provide valuable data to inform your strategy moving forward.

Include a double opt-in for new subscribers

Implementing a double opt-in process for new subscribers can significantly improve the quality of your email list. With double opt-in, users who sign up for your emails must confirm their subscription by clicking a link in a confirmation email. This extra step ensures that only truly interested individuals join your list, reducing the likelihood of future unsubscribes. While it might slightly slow down list growth, the resulting list will be more engaged and less prone to unsubscribes. Double opt-in also helps protect against spam complaints and improves your overall sender reputation.

Segment your list by interest

Segmentation is a powerful tool for reducing unsubscribe rates. By dividing your list into smaller groups based on specific criteria like interests, purchase history, or engagement level, you can create more targeted and relevant email campaigns. 

For example, using Klaviyo's segmentation features, you could create separate segments for customers interested in different product categories, or for those who have engaged with specific types of content in the past. This allows you to tailor your messaging and offers to each group's preferences, increasing relevance and reducing the chance of subscribers feeling that your emails don't apply to them.

Create valuable and personalized content

At Growth Gurus, we emphasize the importance of creating high-quality, personalized content that offers real value to your subscribers. This means going beyond generic promotional emails and focusing on content that addresses your audience's specific needs, challenges, and interests. Use the data you have about your subscribers to craft personalized recommendations, targeted offers, or educational content that's relevant to their past interactions with your brand. Leverage tools like Yotpo to incorporate user-generated content, which can add authenticity and social proof to your emails. Remember, the more value your emails provide, the less likely subscribers are to opt-out.

Don't spam

Avoid spammy practices that can quickly lead to unsubscribes. This includes using misleading subject lines, excessive use of capital letters or exclamation points, and sending irrelevant content. Be transparent about what subscribers can expect from your emails, and deliver on those promises. Maintain a consistent brand voice and style across your emails to build trust and familiarity with your audience. Remember, every email you send should have a clear purpose and provide value to the recipient.

Avoid spammy subject lines

Craft clear, concise, and engaging subject lines that accurately reflect the content of your emails. Avoid clickbait or overly promotional language that might come across as spammy. Instead, focus on communicating the value or benefit that the email offers to the subscriber. For example, instead of "AMAZING DEAL INSIDE!!!", try "Your exclusive 20% off coupon awaits". Use A/B testing to experiment with different subject line styles and find what resonates best with your audience. Tools like Klaviyo offer built-in A/B testing features that can help you optimize your subject lines over time.

Make sure the emails are responsive and user-friendly

In today's mobile-first world, ensuring your emails are responsive and user-friendly across all devices is crucial. A poor mobile experience can quickly lead to frustration and unsubscribes. Design your emails with a mobile-first approach, using single-column layouts, large, easy-to-tap buttons, and concise content. Test your emails across various devices and email clients to ensure they render correctly and are easy to read and interact with. Consider using tools like Yotpo to create responsive email templates that look great on any device.

Ask for feedback

Proactively seeking feedback from your subscribers can provide valuable insights into why people might be unsubscribing. Include brief surveys in your emails or as part of the unsubscribe process to understand what's driving subscribers away. Leverage a tool like Okendo to gather profound insights into your customers’ preferences. This could be as simple as a multiple-choice question asking why they're unsubscribing, or a more detailed feedback form for those willing to provide more information. Use this feedback to continually refine your email strategy and address any common issues that might be causing unsubscribes.

Make it easy for people to unsubscribe

While it might seem counterintuitive, making it easy for people to unsubscribe can actually benefit your email marketing in the long run. A clear and straightforward unsubscribe process demonstrates respect for your subscribers' preferences and can improve your overall sender reputation. Include an easily visible unsubscribe link in every email, and ensure the process is simple and quick. Consider offering alternatives to unsubscribing, such as reducing email frequency or updating preferences, which can help retain subscribers who might otherwise opt-out completely.

Unsubscribe rates across industries

Unsubscribe rates can vary significantly across different industries due to factors such as content type, audience expectations, and email frequency. For example, e-commerce businesses might experience higher unsubscribe rates due to the promotional nature of their emails, while B2B companies might see lower rates due to more targeted, industry-specific content. This means there may be higher acceptable email unsubscribe rates in certain sectors. Understanding these variations can help you establish an email unsubscribe benchmark and set realistic goals for improvement.

Reasons for high email unsubscribe rate

Some of the most common reasons for a high email unsubscribe rate include:

  • Irrelevant content
  • Inconsistent sending frequency
  • Lack of personalization or segmentation
  • Technical issues
  • Poor email design leads to a bad user experience

Frequently asked questions

Why is the unsubscribe rate high in e-commerce?

Unsubscribe rates in e-commerce can spike due to several factors. One common reason is irrelevant content or a misalignment between the emails sent and the audience’s expectations. For instance, if a subscriber signs up expecting personalized product recommendations and instead gets bombarded with irrelevant offers, they’ll likely leave. 

Frequency also plays a role. If you’re emailing too often or too little, people may lose interest or feel overwhelmed. Understanding the acceptable newsletter unsubscribe rate for your industry and maintaining consistency with your messaging is key.

Why do emails bounce?

Bounced emails typically occur when there’s an issue with the recipient's email address or inbox. Hard bounces happen when the email can’t be delivered due to reasons like an invalid email address, while soft bounces may occur due to temporary issues such as a full inbox or server problems. High bounce rates can impact your deliverability and your email marketing platform's sender reputation, making it critical to maintain a clean and up-to-date list.

How can I address technical issues leading to unsubscribes?

Technical issues such as poor email formatting, broken links, or unresponsive designs can cause frustration and drive subscribers away. To avoid this, always test your emails across different devices and email clients before sending them out. Platforms like Klaviyo and Yotpo have built-in preview features to help you catch errors before they become subscriber issues. Ensuring that all CTAs, images, and links work correctly will also help reduce unsubscribes.

What can be the cause of a prolonged high unsubscribe rate?

A prolonged high email unsubscribe rate can be a result of various issues. It might be due to a lack of content relevance, poor segmentation, or inconsistent sending schedules. Sometimes, it's simply because the subscriber list is outdated, and those on it are no longer interested in the content. Another potential cause could be failing to properly manage subscriber expectations from the start—this is where a double opt-in can help, as it ensures subscribers are genuinely interested.

Why is my unsubscribe rate so high?

If you’re consistently experiencing a high unsubscribe rate, you’ll want to evaluate multiple aspects of your email strategy. Start by looking at the quality and relevance of your content. Are you delivering what you promised when subscribers signed up? Next, analyze your sending frequency and list segmentation. Sending too many irrelevant emails is a fast way to increase your unsubscribe rate. Finally, technical issues such as poor design, broken links, or a frustrating user experience can all contribute to higher-than-average unsubscribe rates.

Conclusion

Understanding the email unsubscribe rate is essential for any e-commerce business aiming to thrive in today’s competitive landscape. A high unsubscribe rate not only hampers your email marketing efforts but can also impact your overall brand reputation.
