TL;DR: Hiding in plain sight is the most important—and most overlooked—email segment: shoppers who open emails but don’t click through. Learn why this group is the linchpin of your email marketing success—and how you can better engage and monetize them.
Overlooked and Undervalued—But Essential to Compete
With platforms like Klaviyo offering an overwhelming number of segmentation options, it can be difficult to determine which segments—beyond the standard “active in the last X days”—are truly impactful.
This often leaves marketers confused, unable to see the forest for the trees.
In this post, we invite you to set aside all other segmentation options for a moment and focus on the single largest and most important segment: shoppers who periodically open emails but never click through.
This group typically makes up more than 50% of all contacts in a typical email list. It’s also the most valuable segment, as it represents almost 100% of future email-driven revenue.
Who Are the Openers Who Don’t Click
The nature of the open–no-click email segment is poorly studied and, generally speaking, widely misunderstood.
Assuming these email opens are genuine user actions—not false signals from email security systems—an open represents a clear top-of-funnel signal of interest in the brand.
Confused by the lack of clicks, marketers may assume these subscribers aren’t potential buyers and give up on them too early—or worse, target them with aggressive promotions as if they’re ready to buy.
Either approach leads to the same outcome: loss of contacts—either through direct action by removing them from the list, or indirectly by driving them to disengage due to ineffective marketing.
The most effective way to understand this segment is through the 95–5 Rule of Marketing, derived from decades of research across thousands of brands.
It states that only 5% of potential buyers are actively in-market at any given time, while the remaining 95%—in this case, the open-no-click email segment—are not yet ready to purchase.
Yet their repeated email opens indicate ongoing interest in the brand, making them highly valuable once they’re ready to buy.
Challenge: Messy Middle
Email shoppers who open but don’t click are the embodiment of what Google calls the “Messy Middle”—consumers navigating a complex, non-linear path to purchase.
A closer look reveals that this segment includes several distinct sub-groups:
- Some have just discovered the brand and haven’t shown enough interest to opt in—they were added via identity resolution tools.
- Others have opted in, signaling stronger intent, but have little or no activity on the online store.
- Then there are past buyers or previously engaged visitors whose behavior shifts over time due to seasonality, product interest, or other factors.
The key to engaging these open-no-click shoppers is to keep them aware of the brand, spark curiosity about its offerings, and nurture interest until they’re ready to act.
Doing that means moving beyond one-size-fits-all campaigns by showing products in emails that closely match each shopper’s implied needs and stage in the buying journey.
Of course, that’s easier said than done.
Customer data is often sparse, inconsistent, and fragmented.
And traditional personalization tools—like Klaviyo’s product feeds or similar third-party apps—aren’t equipped to drive meaningful engagement with this audience.
Solution: InMail Shop™
Effectively managing the open-no-click segment requires a complete shift in marketing strategy.
Sending the same types of emails and expecting more contacts to click through to the store is out. What’s in is a strategy that brings the store experience directly into the email itself.
Implementing this strategy can be as simple as using InMail Shop™—a content block that streams a highly personalized, mini version of the online store directly into the body of the email.
That way, recipients can explore relevant products before they’re ready to buy—without ever leaving their inbox.
InMail Shop™ is a core feature of Email Pulse, an ecommerce-specific generative AI solution built to take email personalization to the next level.
Unlike ChatGPT and similar generative AI tools that rely on word-based prompts to generate text, Email Pulse uses a wide range of ecommerce signals—such as customer profiles, lifecycle stages, email and on-site behavior, and product metadata—to generate dynamic, relevant product streams personalized for each individual shopper.
Can Klaviyo support this kind of strategy?
Dynamic feeds provided by Klaviyo are a powerful feature of the platform.
However, when it comes to personalization, Klaviyo offers only one personalized dynamic feed—“Products a customer may also like.”
While it’s a step in the right direction, this single personalized feed comes with significant limitations—ranging from restricted input data and limited algorithm capabilities to narrow usage constraints.
