Email Fatigue in Email Marketing: What is It and How to Avoid It

Every good salesman knows making a pitch is all about finding a sweet spot; you have to find a rhythm where both you and a prospective customer benefit from an interaction. To do this, you have to really be tuned into what your customer wants. If you push too hard, they will dislike you, but if you don’t push hard enough, they will lose interest. It’s all about balance.
Let’s extend this example to email marketing. When you push too hard — email fatigue happens.
But how many emails is too much, and how many is too little? You want to remain fresh in the minds of your recipients, yet avoid bombarding them with emails.
What’s the best way to avoid this phenomenon known as email fatigue?
In this detailed guide, we share everything you need to know about email burnout and ways to prevent it among your email marketing subscribers.
Email Fatigue Meaning
Email fatigue or inbox fatigue is the sense of frustration email users feel when their inboxes become flooded with too many messages.
These could mean excessive workplace emails, promotional emails, and irrelevant communications. It can result in users ignoring, deleting, or unsubscribing from emails. Users experiencing email fatigue at work feel stressed or see reduced productivity due to constant email management.
Email triage methods can help users manage fatigue better.
What is Email Marketing Fatigue?
Email marketing fatigue or email saturation occurs when recipients become overwhelmed or disengaged due to receiving too many emails.
Overly repetitive messages from a brand can lead to:
- Lower open rates,
- Decreased email engagement,
- An increase in the email unsubscribe rate.
Higher unsubscribes can lead to a reduced audience in email campaigns, which affects long-term results.
But how many marketing emails are too many?
The ideal number of marketing emails depends on your audience, industry, and content quality. A general guideline is to avoid sending more than 1-3 emails per week unless your subscribers expect to hear from you more often and explicitly sign up for more email volume.
What are the Signs of Email Fatigue?

Recognizing signs of customer fatigue is crucial for maintaining a positive relationship with them. You must keep this in mind when building an email content calendar with different types of email campaigns.
Here are common signs your subscribers might be experiencing email boredom:
- Decreased open rates: A noticeable decline in email open rates indicates recipients are becoming disengaged.
- Dip in CTR: If you observe a drop in click-through rates (CTR), it could suggest fading interest or a reluctance to engage with your content.
- Increased unsubscribes: A spike in the number of subscribers opting out of your email list is a clear sign of dissatisfaction.
- Higher spam reports: An increase in the number of recipients marking your messages as email spam indicates dissatisfaction.
- Poor response to interactive content: If your emails typically include CTAs, email surveys, or feedback requests, a lack of response may signal subscriber fatigue.
- Inactive subscribers: If you notice a growing subset of subscribers who haven’t engaged with your emails for an extended period — say, 2-3 months — it may indicate they no longer find value in your content.
- Negative feedback: If you receive direct feedback from your subscribers expressing feelings of being overwhelmed or receiving too many emails, take it seriously!
- Email bounces: An increase in email bounce rate — undeliverable emails — can be a sign your subscriber list contains invalid email addresses.
Been noticing some of these patterns recently? You should be concerned — here’s why.
Why Email Fatigue is Bad News for Email Marketers

Email list fatigue can directly affect your ROI; it can be bad for your brand email marketing efforts if word spreads about you being a spam email sender.
When subscribers experience content fatigue, they may be less likely to open emails, click on links, or take desired actions. This can bring down the effectiveness of your email campaigns.
Here’s how email marketing suffers due to email fatigue among your readers:
- Email engagement: Email fatigue is bad for the engagement rates of your email campaigns. Subscribers who are overwhelmed or disinterested are less likely to open your emails, click on links, or take desired actions.
- Email deliverability: High levels of email tiredness can result in spam complaints and unsubscribes. These negatively impact your reputation with mailbox providers, leading to your emails being filtered to spam folders or blocked altogether.
- Email marketing conversion rates: If subscribers are fatigued, they are less likely to convert on your CTAs (calls to action) or make purchases.
- CAN-SPAM and GDPR compliance: Sending unwanted or excessive emails can lead to legal compliance issues with regulatory authorities such as the CAN-SPAM Act or GDPR.
- Email performance: Effective email marketing relies on achieving a strong return on investment. By emailing disinterested subscribers, you are wasting time and money, which will reflect on your email marketing ROI.
Caring about subscriber email fatigue is essential to protect your email sender reputation. Avoiding email apathy is critical to optimizing conversion rates and preserving email list quality.
Top Causes of Email Fatigue

Before we offer you the solution to email fatigue, let’s review the top causes. It’s possible content marketers are guilty of a few of these, as they excitedly share content with their email list without considering the subscribers’ point of view.
These common factors contribute to email tiredness among readers:
- Excessive email volume: Sending too many emails in a short period or bombarding subscribers with frequent messages can lead to fatigue. Subscribers may feel overwhelmed and start ignoring or unsubscribing from the emails.
- Repetitive email content: If the content of the emails becomes repetitive or lacks variety, subscribers may lose interest. Seeing the same types of promotions, messages, or offers repeatedly can lead to a decline in engagement.
- Irrelevant messages: Sending emails irrelevant to the interests or needs of the subscribers can contribute to fatigue. Subscribers are more likely to engage with emails providing value and meeting their expectations.
- Poor personalization: Generic, one-size-fits-all emails may not resonate with subscribers. Email personalization and targeted email marketing can help maintain subscriber interest.
- Bad timing: Sending emails at inappropriate times, such as too frequently or during off-hours, can contribute to fatigue. Email marketers must figure out the best time to send emails.
If any of these factors seem familiar, cease them immediately. But there’s more to it — if you want to learn how to prevent email apathy from happening, ever, this next section has you covered!
How to Prevent Email Fatigue in Subscribers
Finally, we get to the solutions! If you want to know how to avoid a reducing audience in email marketing, it’s time to remedy this.
Here’s a table explaining the different methods of tackling email fatigue in subscribers:
Step | Explanation |
---|---|
Study your campaign metrics | Examining your metrics can give you insight into what’s working and what’s not. |
Segment your lists | Segmentation is the first step to sending relevant content, which helps prevent email fatigue in your recipients. |
Personalize the content | Sending personalized content is more valuable for a reader than cookie-cutter messages. |
Monitor feedback | Are your readers voicing their thoughts on your content? Ask for feedback, but also monitor social media channels or conduct closed-group surveys for input. |
A/B testing | This is the best way to figure out what your subscribers love and respond to. |
Email timing | Timing your emails perfectly is essential to preventing email fatigue. |
Next, let’s explore each of these elements in detail.
Monitor Your Metrics to Learn Where Email Fatigue Occurs

To check if your subscribers are tired of the email influx, study your email campaign metrics on your ESP’s dashboard. Besides this, you can also examine your social media and website analytics pages.
Here’s how to use data to resolve email fatigue issues.
Study the Drop-off
Examine your engagement rates to get an idea of when the email tiredness could have occurred. Was there an event that triggered it? Was it a new style of content? Are you keeping your content fresh for your subscribers? Addressing these questions can pull up answers for your problem.
Examine the Landing Page
Study your website analytics to see if your customers are unhappy with the landing page for any reason. Set the correct expectations in your email so the page they visit via the CTA button is clutter-free and helps in quick conversion. You can boost conversion rates by landing page speed optimization.
Check Social Media for Complaints
Your subscribers may be talking about your content or messages on your social media platforms. Monitor your pages or conduct polls on social media platforms for additional insight.
Check your Email Infrastructure for Technical Issues
Asking yourself these questions can help detect and resolve technical issues:
- Are there unexplained dips in your open rates and click rates?
- Is there an email accessibility issue causing subscribers to avoid interacting with your emails?
- Is there any change in email delivery rates or email deliverability rates?
Next, run these tests:
- Test your emails to verify the load times are good.
- Test your email infrastructure to ensure emails send correctly.
- Check for queued emails or deferred emails in your email outbox.
With adequate data scrubbing, you should be able to pinpoint the exact point where your readers got overwhelmed by your emails!
Email List Segmentation Makes Emails More Relevant

A powerful email segmentation strategy can divide your email list into smaller, targeted segments. Implementing the best segmentation tactics is the most effective method of reducing email fatigue, which is why it’s so high up on this list.
Let’s review the benefits segmentation brings to email burnout.
1. Relevant Content Delivery
Segmentation allows you to fine-tune your email content to the unique preferences, interests, and behaviors of each segment. By sending more relevant and personalized content, you increase the chances of capturing your audience’s attention and reducing email apathy.
2. Optimized Email Frequency
Different segments of your audience may have varying preferences when it comes to email frequency. Segmentation enables you to adjust the frequency of your emails based on the characteristics of each segment, preventing overmailing and minimizing the risk of recipients being overwhelmed by too many emails.
3. Targeted Offers
Segmentation enables you to target specific groups with promotions and offers that resonate with their needs and preferences. This increases the likelihood of engagement and reduces the perception of receiving irrelevant emails.
4. Behavioral Targeting
Behavioral segmentation — based on user behavior, such as past purchases, website interactions, or email engagement — allows you to send targeted messages aligned with subscribers’ actions. This ensures your emails are in tune with their interests, reducing the risk of fatigue. We will expand on this a bit more in the personalization section.
5. Targeting is Relevant to Position in Marketing Funnel
Your subscribers will go through various email marketing funnel stages in their relationship with your company; from new prospects to loyal customers. Imagine a repeat customer receiving a welcome email — they’d see it as a waste of time and some may even be offended.
Segmentation based on these stages allows you to send appropriate content at each stage. It prevents subscribers from receiving content irrelevant to their current position in the email marketing customer journey.
6. Geographic Segmentation
Your subscriber hears a notification on their phone and checks it to see an email for you. The email informs them of a massive sale on your products at your store, except… the store is in another state!
Geographic segmentation helps avoid this scenario. If your audience is spread across different regions, geographic segmentation can be beneficial. It allows you to send localized content, promotions, or event invitation emails — this ensures your emails are more pertinent to the specific location of each segment.
Email list segmentation allows you to treat your subscribers as individuals with unique preferences. By sending targeted and personalized emails to specific segments, you can significantly reduce the risk of email burnout!
Personalized Content Makes Your Customer Feel Special
Sending mass personalized emails is a powerful strategy to address email fatigue. It creates a more relevant and engaging experience for individual subscribers.
Below, we review 7 ways in which sending personalized content reduces burnout from emails.
1. It Improves Relevance
Personalization allows you to tailor your content to the specific interests, preferences, and choices of each subscriber. By delivering content aligning with their individual needs, you increase the relevance of your emails, making readers more likely to appreciate and engage with your messages.
2. It Keeps Content Exciting
Personalized content helps you diversify your messaging. Subscribers may experience fatigue when constantly receiving generic or repetitive messages. By incorporating personalization, you can vary the content based on factors such as past purchases, browsing history, or demographic information.
3. Readers Get a Superior User Experience
Providing a personalized user experience demonstrates you understand and value your subscribers. It creates a sense of connection and makes recipients feel you curated content specifically for them, reducing the likelihood of fatigue.
4. It Can Boost Open Rates
Tailoring subject lines for individual subscribers can increase open rates. Recipients are more likely to open emails that immediately resonate with their interests, reducing the chances of them ignoring or deleting your message.
5. Dynamic Content Increases Engagement
Including dynamic email content allows you to create personalized sections within your emails. This excites readers; you can include personalized product recommendations, localized offers, or use subscriber-specific data for innovative sections.
6. It Helps Follow Up on Website Actions
Use behavioral triggers to send personalized emails based on subscriber behavior on your website. For example, if a prospect abandons a shopping cart, send a personalized follow-up email with information about the items left in the cart to re-engage them.
7. Personalization Allows You to Send Custom Offers
Send personalized offers and product recommendations to your subscribers based on their purchase history or browsing behavior. This adds value to your emails by showcasing products or services matching their preferences.
You can combat email burnout by delivering more relevant, varied, and personalized messages to individual subscribers. This approach enhances the subscriber experience and creates a more positive impression of your brand’s email messages.
Is Your Email Timing Right?
How many times have you checked your phone to see an email notification and decided to check it later, only to completely forget about it? If it happens to you, it happens to your subscribers too.
That’s why you need to nail the timing of your marketing emails.
Email timing is the strategic scheduling of email campaigns to ensure you send messages at optimal times for maximum impact and engagement. Sending emails at appropriate times respects the daily routines and schedules of your subscribers. By avoiding inconvenient times, such as late at night or during busy work hours, you reduce the likelihood of your emails seeming intrusive.
Sending emails in the right time slots can lead to higher open rates. Such emails are more likely to be engaging and valuable, contributing to a positive experience for subscribers.
The benefits to your open rates could extend to click-through rates, too. Sending emails when subscribers are more receptive can result in improved CTR, as individuals are more likely to interact with your content.
Timing isn’t just about the day or week — time your emails to coincide with specific seasons, holidays, or events to enhance engagement. Holiday email marketing strategies ensure your messages align with the activities of your readers.
By being precise with the timing of your email campaigns, you demonstrate a commitment to delivering content when it is most likely to be well-received. This approach reduces the risk of subscribers being overwhelmed by your emails.
List Hygiene Benefits Everyone
Email list management is crucial to maintaining a healthy and engaged subscriber list. It involves regularly cleaning and managing your email list to confirm it only contains active and interested recipients. Cleaning your list ensures you get great engagement rates and disinterested subscribers stop receiving your emails — it’s a win-win.
Email list hygiene plays a significant role in reducing email tiredness for several reasons:
- It ensures messages are relevant to active and engaged subscribers.
- It helps maintain a positive sender reputation for better inbox placement.
- Cleaning lists minimizes bounce rates and ensures you have a valid email address list.
- You can remove disinterested subscribers, reducing the likelihood of spam complaints.
- List scrubbing helps engagement metrics by focusing on an interested audience, which is also great for resource management.
- List cleaning is vital for compliance with email marketing regulations as you confirm unsubscribe requests.
Regular list maintenance has a lot of benefits; that’s why we introduced the automated list-cleaning feature on Campaign Refinery. It keeps an eye on troublemakers like spam traps, bots, seed accounts, invalid emails, and complainer IDs so your deliverability never suffers because you sent an email to them. And you don’t have to lift a finger — our algo takes care of it all!
By ensuring your list only contains engaged readers, you greatly reduce the chances of email boredom. Additionally, mailbox providers pay attention to your engagement rates and assign a higher sender score to you, which means your emails land in the inbox more often!
A/B Testing Helps Discover Subscribers’ Likes and Dislikes
Email A/B testing, also known as split testing, is a powerful method to optimize various elements of your email campaigns by comparing different versions and determining which performs better. While A/B testing itself doesn’t directly reduce email burnout, it is an invaluable tool for refining your email marketing strategy. It helps reduce fatigue and assist with overall engagement.
Here are the elements you can experiment with during your testing process:
- Email subject lines: Variations in wording, length, or tone.
- Email sender name: Testing a personal name vs. a brand name.
- Email content: Different messaging or content structure.
- Email CTA: Testing different CTA buttons, text, or placement.
- Email design: Variations in the type, size, or placement of images.
You can figure out the perfect formula for different segments of your email list. Next, let’s look at how you can tackle your email fatigue issue by studying your A/B test results.
Here’s a table explaining how A/B testing contributes to reducing email ennui:
Factor | Role in Reducing Email Fatigue |
---|---|
Content relevance | A/B testing helps identify engaging and relevant content. Tailoring emails based on results reduces fatigue. |
Email timing | Experimenting with different send times ensures emails reach subscribers when they are most receptive, reducing fatigue. |
Email frequency | Testing variations in frequency helps find the right balance, preventing excessive email volume and subscriber overload. |
Subject lines | A/B testing helps optimize subject lines and preview text, reducing fatigue by grabbing attention effectively. |
Personalization | Testing personalized elements refines strategies for more engaging content, reducing fatigue from generic messages. |
Segmentation testing | Testing different segments ensures targeted content, minimizing fatigue from irrelevant messages. |
With A/B testing, you can resolve email fatigue issues and run campaigns generating excellent engagement.
Run Re-Engagement Campaigns
Re-engagement campaigns can be an effective strategy to win back disengaged subscribers who may be overwhelmed by too many emails. Such campaigns aim to reconnect with inactive subscribers, rekindle their interest, and encourage them to become active again.
Here’s a guide on how to implement a re-engagement campaign:
- Determine criteria for identifying inactive subscribers. This could be based on factors like lack of opens, clicks, or engagement over a specific period — say, 2-3 months.
- Create a segment with your inactive subscribers. This allows you to tailor re-engagement content specifically for this group.
- Create an attention-grabbing email addressing the fact you’ve noticed their inactivity and wish to re-engage.
- Include a clear and convincing CTA in your emails.
- Provide options for subscribers who might want to adjust their email preferences, such as frequency or content preferences.
- Use urgency or exclusivity in your messaging to encourage immediate action. Limited-time offers or exclusive access can motivate subscribers to re-engage sooner. This is why we offer Evergreen Flash Sales at Campaign Refinery; the engagement rates are simply mind-blowing.
- Personalize the re-engagement email by using the subscriber’s name and referencing their previous interactions or preferences.
- Track campaign performance. Note the opens, clicks, and any feedback you receive. Use this data to assess effectiveness.
- If subscribers still do not engage after the re-engagement campaign, consider removing them from your list. This is beneficial for list hygiene and improves overall engagement metrics.
- Apply what you’ve learned to future campaigns and adjust your approach based on subscriber feedback.
Re-engagement campaigns are not a one-size-fits-all solution; their effectiveness may vary depending on various factors. However, they are effective at times and can help renew subscriber interest in your email communications.
