Dealing with a manager who doesn't see eye-to-eye on email marketing strategies, especially concerning segmentation and sunsetting campaigns, can be incredibly frustrating. I've been in situations where the numbers clearly pointed to one path, but internal resistance made it feel like an uphill battle. My email click rates have been stuck at 0.31% for over a year, with a 59.35% unique open rate, 0.26% unsubscribe rate, and a 0.02% complain rate. While the delivery rate looks high at 99.80%, these low engagement metrics are a clear red flag that something needs to change.
The core of the disagreement often comes down to a fundamental difference in how success is measured. Many managers prioritize raw numbers, like the total number of clicks or the size of the email list, over critical engagement rates. This perspective overlooks the long-term damage that low engagement can inflict on your sender reputation and overall deliverability. It's not just about getting emails into the inbox, but ensuring they are opened and, most importantly, acted upon.
The goal isn't just to send to as many people as possible, but to send relevant content to an engaged audience. Sending to unengaged subscribers can drag down key metrics like click-through rates, even if open rates seem decent. It can also lead to higher spam complaint rates and, eventually, blocklisting (or blacklisting), harming your ability to reach even your most valuable subscribers. The challenge is showing how seemingly smaller, more engaged lists actually lead to better business outcomes.
The power of segmentation
One of the most effective strategies for improving email click rates is through audience segmentation. This involves dividing your subscriber list into smaller, more specific groups based on their demographics, behaviors, or preferences. Instead of sending a generic message to everyone, you tailor your content to resonate with each segment, making the email far more relevant to the recipient.
When recipients receive emails that are highly relevant to their interests, they are much more likely to open them and, crucially, click on the calls to action. This isn't just about boosting the percentage; it's about driving more meaningful engagement and conversions. It's a fundamental principle of effective email marketing, directly impacting revenue and engagement.
For example, you might segment users who frequently click on product updates separately from those who only engage with promotional offers. By sending product-focused content to the former and sales-driven content to the latter, you increase the likelihood of clicks from both groups. Mailchimp also emphasizes the importance of segmenting emails to improve click-through rates, highlighting how targeted content performs better. You can find more on the ways to improve your email click through rate in their resources.
The blanket approach
Sending the same email to every subscriber, regardless of their past interactions or interests. This often leads to lower overall engagement.
Content relevance: Less personalized content means fewer clicks.
Sender reputation: High unsubscribe and spam complaint rates can harm your sending domain reputation.
The segmented approach
Dividing your audience into smaller, targeted groups to deliver highly relevant and personalized content. This significantly boosts engagement.
Content relevance: High personalization leads to increased clicks.
Sender reputation: Lower complaint rates and improved deliverability due to better engagement.
Why sunsetting is crucial
Sunsetting campaigns, or re-engagement campaigns followed by removal of inactive subscribers, are critical for maintaining a healthy email list and preventing your domain from being added to a blocklist (or blacklist). Unengaged subscribers can severely dilute your overall engagement metrics. Email service providers (ESPs) and internet service providers (ISPs) like Google and Yahoo closely monitor engagement. Sending to large numbers of unengaged recipients signals low quality, which can lead to your emails landing in the spam folder or being blocked entirely.
Inactive subscribers also pose a risk of turning into spam traps. These are dormant email addresses that ESPs use to catch spammers. Hitting a spam trap can immediately land your domain on a blacklist, making it incredibly difficult to reach anyone's inbox. Removing these contacts, even if it shrinks your list, protects your long-term deliverability.
A clean list, even if smaller, will yield higher open and click rates, improve your sender reputation, and ultimately lead to better campaign performance and return on investment. It's about quality over quantity. Klaviyo supports this view, stating that cleaning your lists and segmenting can improve click rates.
Best practice for inactive subscribers
Identify inactive subscribers: Define inactivity (e.g., no opens/clicks in 90-180 days).
Re-engagement campaigns: Send a series of emails trying to win them back with special offers or updated content.
Remove unengaged: If re-engagement fails, remove them from your active mailing list to protect your sender reputation. This prevents issues like landing on an email blacklist.
Communicating with management
The key to getting your manager on board is to shift the conversation from raw list size or total clicks to the true impact on business goals. Focus on the money. Explain that improved click rates lead to higher conversions, better return on investment (ROI), and ultimately, more revenue. A smaller, highly engaged list is far more valuable than a large, disengaged one.
I've found it effective to run controlled A/B tests or split sends. Compare a segment that applies engagement criteria against the standard audience your manager prefers. Show tangible results: higher click rates, better conversion rates, and lower spam complaints from the segmented group. This data is hard to argue with, even if the absolute number of recipients is smaller.
Frame segmentation and sunsetting not as reducing reach, but as optimizing the existing reach for maximum impact. Highlight the risks of not doing so, such as ending up on an email blocklist or seeing your emails go directly to spam. Tools like Outlook's new sender requirements, for example, heavily emphasize engagement.
Remember, the goal is to shift your manager's perspective from a short-term, volume-based view to a long-term, profitability-focused one. Provide clear data and compelling arguments about the benefits of a healthy, engaged email list for the business's bottom line.
Views from the trenches

Driving email engagement
Improving email click rates in the face of managerial resistance requires a strategic approach centered on data and long-term value. While it's tempting to focus on simply growing the list size, true success in email marketing comes from cultivating an engaged audience. Low click rates are a symptom of a deeper problem, often stemming from a lack of effective segmentation and a reluctance to remove inactive subscribers.
Embracing segmentation allows you to send highly relevant content, which naturally boosts engagement and click-through rates. Implementing sunsetting campaigns, despite initial concerns about list size, is crucial for maintaining a healthy sender reputation, avoiding spam traps, and ensuring your emails actually reach the inbox. It's about recognizing that a smaller, more responsive list is far more profitable and sustainable.
The challenge often lies in educating stakeholders who may not fully grasp the intricacies of email deliverability. By presenting clear, quantifiable data and framing your arguments around tangible business outcomes, you can make a compelling case for these vital strategies. Prioritizing click rates over raw list numbers will lead to better overall email performance and ultimately, contribute significantly to your company's success.
