Email unsubscribe rates: a complete guide

Introduction

Email marketing is one of the most effective ways to reach customers, but it comes with a unique challenge: unsubscribes. An unsubscribe occurs when a recipient opts out of receiving future emails from your business. While it’s a normal part of email marketing, a high unsubscribe rate can harm your brand’s reputation, reduce revenue potential, and affect campaign performance.

In this guide, we’ll explore what email unsubscribe rates are, how to calculate them, and strategies to keep your list healthy while minimizing unsubscribes.

What are email unsubscribe rates?

Email unsubscribe rates measure the percentage of recipients who opt out of your email list after receiving a specific email campaign. It’s a critical metric for assessing email list health and overall customer satisfaction.

Why do email unsubscribe rates matter?

A low unsubscribe rate indicates that your email content resonates with your audience, while a high rate suggests potential problems like irrelevant messaging or email overload. Tracking unsubscribe rates helps maintain a clean, engaged email list, ensuring better email deliverability and higher campaign ROI.

How are email unsubscribe rates calculated?

The standard formula for calculating email unsubscribe rates is:

Unsubscribe rate (%) = (Number of unsubscribes / Emails delivered) × 100

Example:

• Emails delivered: 10,000
• Unsubscribes: 150

Unsubscribe rate = (150 / 10,000) × 100 = 1.5%

Industry benchmark averages

Email unsubscribe rates vary across industries and email types. Here are common industry benchmarks:

Industry	Average unsubscribe rate
E-commerce & retail	0.2% – 0.7%
Software & SaaS	0.2% – 0.5%
Nonprofits & charities	0.1% – 0.3%
B2B (business services)	0.2% – 0.6%
Health & wellness	0.2% – 0.4%
Financial services	0.2% – 0.5%

An unsubscribe rate below 0.5% is generally considered healthy, while rates above 1% may indicate deeper issues in your email marketing strategy.

Factors affecting email unsubscribe rates

Several factors can influence email unsubscribe rates, either positively or negatively. Understanding these drivers allows businesses to adjust their email marketing strategies and keep subscribers engaged.

Email frequency

The issue:
Sending emails too frequently can overwhelm subscribers, leading to unsubscribe requests. On the flip side, sending emails too infrequently can cause subscribers to forget your brand, making them more likely to unsubscribe when they finally hear from you.

Best practice:

• Find the right balance: Test different sending frequencies to see what works best for your audience.
• Let subscribers choose: Offer a preference center where subscribers can set how often they want to hear from you.

Content relevance

The issue:
Emails that are irrelevant, repetitive, or lack value can quickly frustrate recipients. If subscribers feel that your content doesn’t meet their needs or expectations, they will opt out.

Best practice:

• Segment your list: Group subscribers based on behavior, purchase history, or interests.
• Personalize content: Use names, previous purchases, or interests to deliver tailored content.
• Offer value: Send a mix of promotions, educational content, and exclusive updates.

Email design and user experience

The issue:
Poor email design, hard-to-read layouts, and broken links can cause subscribers to lose interest. If emails look cluttered or don’t display well on mobile devices, users are more likely to unsubscribe.

Best practice:

• Use mobile-responsive templates: Ensure emails are readable on all devices.
• Keep it clean and simple: Use clear headlines, bullet points, and a strong call-to-action (cta).
• Test before sending: Test emails on multiple devices and email clients to avoid formatting issues.

Subscription expectations

The issue:
If subscribers don’t get what they expected when signing up, they may feel misled and choose to unsubscribe.

Best practice:

• Be transparent during sign-up: Clearly explain what type of content subscribers will receive and how often.
• Stay consistent: Deliver on your promises by sticking to the content and schedule advertised at sign-up.

Permission and consent

The issue:
Sending emails without explicit consent can result in immediate unsubscribes and damage your sender reputation.

Best practice:

• Use double opt-in: Confirm subscribers’ interest by asking them to verify their email addresses after signing up.
• Follow privacy regulations: Stay compliant with gdpr, ccpa, and can-spam laws to maintain a trustworthy brand image.
• Include an easy opt-out link: Make unsubscribing simple and straightforward to avoid customer frustration.

Sender reputation

The issue:
Emails from unknown or suspicious senders may cause recipients to unsubscribe—or worse, mark emails as spam.

Best practice:

• Use a recognizable sender name: Include your brand name in the “from” field.
• Authenticate your domain: Use spf, dkim, and dmarc protocols to improve deliverability.
• Maintain a consistent identity: Avoid changing sender names or email addresses frequently.

Email timing

The issue:
Sending emails at inconvenient times can lead to lower engagement and increased unsubscribes.

Best practice:

• Test send times: Use a/b testing to determine when subscribers are most likely to engage.
• Consider time zones: Schedule campaigns based on recipients’ local times for better visibility.

How to reduce email unsubscribe rates

While some email list churn is inevitable, there are effective strategies to reduce unsubscribe rates while maintaining a healthy and engaged subscriber base. Here are proven tactics to keep your audience interested and loyal.

Personalize email content

Why it works:
Personalized emails feel more relevant, increasing engagement and reducing the likelihood of unsubscribes.

Best practices:

• Use names: Address subscribers by their first names in subject lines and greetings.
• Segment your audience: Create targeted campaigns based on demographics, past purchases, or browsing behavior.
• Send tailored offers: Recommend products or services that match subscribers’ interests.

Example:
“Hi Alex, based on your recent purchase, you might love these new arrivals!”

Use clear and honest subject lines

Why it works:
Misleading subject lines can create frustration, leading to higher unsubscribe rates.

Best practices:

• Be transparent: Clearly communicate what the email is about.
• Avoid clickbait: Don’t promise something you can’t deliver.
• Create curiosity: Use action-driven language that sparks interest without exaggeration.

Example:

• Good: “Your exclusive holiday deal is here!”
• Bad: “You won’t believe what we have for you (limited time)!!!”

Maintain a consistent schedule

Why it works:
Consistency helps set expectations, making subscribers less likely to feel overwhelmed or forgotten.

Best practices:

• Create a content calendar: Plan campaigns and newsletters ahead of time.
• Test frequency: Experiment with sending emails weekly, bi-weekly, or monthly.
• Set clear expectations: Let subscribers know how often they’ll hear from you at sign-up.

Create a preference center

Why it works:
Allowing subscribers to control what they receive and how often keeps them engaged on their terms.

Best practices:

• Offer frequency options: Let subscribers choose between weekly, bi-weekly, or monthly emails.
• Content type selection: Allow them to select topics they care about (e.g., promotions, product updates, educational content).
• Include a pause option: Let users temporarily pause email notifications instead of unsubscribing.

Deliver value-driven content

Why it works:
Subscribers will stay if they find your emails valuable, whether through discounts, tips, or exclusive insights.

Best practices:

• Balance promotions and insights: Alternate between promotional offers and informational content.
• Provide exclusive perks: Offer early access to sales, vip-only deals, or members-only content.
• Educational content: Send how-to guides, industry news, and product tutorials.

Example:
“Here’s your 20% off code – plus 5 expert tips for making the most of your purchase!”

Optimize email design and user experience

Why it works:
Well-designed emails encourage engagement, while poor design can drive users away.

Best practices:

• Use responsive templates: Ensure emails look great on mobile devices and desktops.
• Simplify the layout: Use clean designs with clear headlines, images, and ctas.
• Add clear ctas: Make the next steps obvious with prominent buttons like “shop now” or “learn more.”

Send welcome and onboarding emails

Why it works:
A great first impression can set the tone for future engagement, reducing the risk of unsubscribes.

Best practices:

• Send a warm welcome: Greet new subscribers with a personalized welcome email.
• Introduce your brand: Explain what they can expect and how often they’ll receive emails.
• Offer a special perk: Consider including a discount code or free resource as a sign-up incentive.

Re-engage inactive subscribers

Why it works:
Reactivating disengaged subscribers keeps your list clean while giving users another chance to stay connected.

Best practices:

• Send a re-engagement campaign: Offer special deals or ask if they still want to receive your emails.
• Use attention-grabbing subject lines: Phrases like “we miss you!” or “is this goodbye?” can rekindle interest.
• Offer opt-down options: Allow subscribers to reduce email frequency instead of opting out entirely.

Monitor engagement and adjust campaigns

Why it works:
Tracking key email metrics helps identify potential unsubscribe triggers before they become a problem.

Best practices:

• Check engagement metrics: Monitor open rates, click-through rates, and time spent reading emails.
• a/b test campaigns: Test different subject lines, email designs, and offers.
• Review feedback: Consider customer surveys and direct feedback from subscribers.

Comply with data privacy laws

Why it works:
Following legal regulations builds trust and ensures subscribers feel secure sharing their personal information.

Best practices:

• Use double opt-in: Confirm subscribers’ email addresses to ensure genuine interest.
• Follow gdpr, ccpa, and can-spam rules: Include an easy-to-find unsubscribe link and provide clear privacy policies.
• Be transparent: Explain how customer data is used and stored.

Best practices for managing email unsubscribes

While reducing email unsubscribe rates is essential, it’s equally important to manage the unsubscribe process effectively. A seamless, transparent, and respectful unsubscribe experience can preserve your brand reputation and even re-engage some users. Here are best practices for managing email unsubscribes:

Provide an easy opt-out option

Why it matters:
Making it difficult to unsubscribe frustrates users, increases spam complaints, and violates email marketing regulations like gdpr and can-spam.

Best practices:

• Visible unsubscribe link: Ensure the link is easy to find, typically at the bottom of the email.
• One-click unsubscribe: Allow users to unsubscribe with one click without requiring them to log in.
• Clear language: Use straightforward language like “unsubscribe here” instead of vague terms like “manage preferences.”

Example:
“If you no longer wish to receive our emails, click here to unsubscribe.”

Use an unsubscribe confirmation page

Why it matters:
An unsubscribe confirmation page can reduce opt-outs by offering alternatives or gathering feedback.

Best practices:

• Offer options: Allow subscribers to adjust their preferences, such as reducing email frequency or changing content categories.
• Ask for feedback: Use a short survey to understand why they are leaving.
• Include a re-engagement message: Offer a last-minute incentive, such as a discount code or exclusive content, to retain the subscriber.

Example:
“We’re sad to see you go! Would you prefer fewer updates or only specific topics? Adjust your preferences below.”

Send a confirmation email after unsubscribing

Why it matters:
Confirmation emails reassure users that their request has been processed while offering a final opportunity for re-engagement.

Best practices:

• Keep it short: Confirm the action and state when they’ll stop receiving emails.
• Include a re-subscription option: Provide a link to re-subscribe if they change their mind.
• Maintain a friendly tone: Use a polite, respectful tone that leaves a positive impression.

Example:
“You’ve successfully unsubscribed from our newsletter. We’ll miss you! If you’d like to return, click here to re-subscribe anytime.”

Monitor feedback loops and spam complaints

Why it matters:
Feedback loops alert you when recipients mark your emails as spam, allowing you to identify potential campaign issues.

Best practices:

• Use email marketing platforms: Tools like mailchimp, sendinblue, or activecampaign track spam complaints and feedback loops.
• Regularly check spam rates: Ensure spam complaints remain below industry standards (typically under 0.1%).
• Investigate sudden spikes: If spam complaints increase, audit recent campaigns for potential triggers like misleading subject lines or aggressive promotion tactics.

Follow privacy regulations and compliance rules

Why it matters:
Compliance with global privacy regulations builds trust, protects user data, and avoids legal penalties.

Best practices:

• Include an unsubscribe link: Make it mandatory in all marketing emails, as required by gdpr, ccpa, and can-spam.
• Process requests promptly: Remove unsubscribed users from your email list within 10 business days.
• Maintain data transparency: Clearly state how user data is stored and used in your privacy policy.

Offer re-engagement campaigns before removal

Why it matters:
Re-engagement campaigns can win back subscribers on the verge of opting out, reducing list churn.

Best practices:

• Send a re-engagement email series: Offer incentives, exclusive content, or a heartfelt message.
• Use a friendly tone: Communicate that you value their subscription and want to improve their experience.
• Offer a pause option: Let users pause emails temporarily rather than unsubscribing.

Example subject lines:

• “We miss you! Here’s 20% off your next order.”
• “Still interested? Let’s stay in touch!”

Keep your email list clean

Why it matters:
Maintaining a clean, up-to-date email list ensures better engagement rates and reduces spam complaints.

Best practices:

• Remove inactive subscribers: Regularly clean your list by removing users who haven’t engaged in 6-12 months.
• Use double opt-in: Ensure that only interested users subscribe by requiring email confirmation after sign-up.
• Monitor bounce rates: Remove email addresses that result in hard bounces to maintain a strong sender reputation.

Respect the customer’s decision

Why it matters:
Respecting unsubscribe requests shows professionalism and builds long-term brand trust.

Best practices:

• Don’t resubscribe automatically: Never add unsubscribed users back to your list without explicit consent.
• Avoid guilt trips: Keep unsubscribe messages friendly and neutral, not pushy or guilt-inducing.
• Stay positive: End with a polite, welcoming message, leaving the door open for future engagement.

Example:
“Thank you for being part of our journey! If you ever want to return, we’d be happy to have you back.”
