Here’s a fact to chew on. Return visitors are 2x more likely to convert than first-timers.
When someone comes back to your site, they’re raising their hand and saying, “Hey, I’m interested.”
The problem? If you’re relying on Klaviyo to track those visitors, you’re leaving money on the table.
Klaviyo’s tracking is tied to a 7-day cookie window. Once that timer runs out, return visitors look like strangers, and your chance to engage them vanishes.
It’s a huge blind spot! Especially for ecommerce brands trying to make every interaction count.
This is where Signal by Customers.ai steps in.
Signal extends your reach by identifying return visitors beyond that seven-day cutoff, giving you the power to re-engage high-intent shoppers when they’re most ready to buy.
The result? More sales, better segmentation, and a serious boost to your ROI.
Let’s break down why re-signaling is the tactic your Klaviyo campaigns have been missing.

Why Re-Signaling Klaviyo Return Visitors Matter More Than You Think
First-time visitors are like window shoppers. They’re browsing, getting a feel for your vibe, and maybe saving something to their cart.
Return visitors? They’re a whole other story.
When someone comes back to your site, they’re not “just looking.” They’re warmed up, curious, and way more likely to convert.
In fact, when someone comes back to your site, they’re 60% more likely to make a purchase than someone who’s visiting for the first time. That’s huge!
Recognizing these visitors is key to scaling your business.
They’re already familiar with your brand, they’ve shown intent, and they’re primed to take action. However, if you don’t know who they are when they return, you can’t re-engage them effectively.
For ecommerce brands, the ability to identify and act on this renewed interest is essential. And that’s why re-signaling matters.
The Klaviyo Return Visitor Identification Problem
Klaviyo is great, don’t get us wrong (we legit built full integrations because we love it) but its cookie-based tracking has a major flaw in that their cookies expire after seven days.
That means if someone visits your site, leaves, and comes back a week later, Klaviyo has no idea it’s the same person.
It’s like they’re hitting the reset button on every returning visitor.
Here’s why that’s a big deal:
- You miss segmentation opportunities: That visitor could’ve been added to a high-intent audience for targeted campaigns. Instead, they’re lumped in with cold traffic.
- No personalization: Without knowing it’s a returning customer, you can’t tailor your messaging to their specific behaviors or interests.
- Engagement falls flat: You’re treating a warm lead like a stranger, which is a surefire way to lose their interest.
And the worst part?
This costs you revenue.
Returning visitors are some of the most valuable traffic you’ll get, but if you’re not recognizing them, you’re missing out.
Plus, your ad spend takes a hit too. Retargeting campaigns aimed at warm audiences miss the mark because Klaviyo isn’t keeping up.
The good news?
This isn’t a lost cause. Tools like Signal make sure those return visitors don’t slip through the cracks. More on that next.

How Re-Signaling Klaviyo Return Visitors Works
Signal transforms how you track, identify, and engage high-intent customers.
Here’s how the re-signaling process works:
Step 1: A Visitor Returns After 7 Days
Let’s say a potential customer checks out your site, leaves, and then comes back two weeks later.
Klaviyo’s cookies expired, so it has no idea who they are. Without Signal, this visitor would be treated as brand new—wasting a golden opportunity to re-engage with a warm lead.
Step 2: Signal Identifies Them
Signal steps up and recognizes the returning visitor, pulling in their data from previous interactions.
Whether they browsed products, abandoned a cart, or subscribed to an email list, Signal knows their history and syncs it back to Klaviyo.
Step 3: Syncs Data to Klaviyo
Now armed with fresh insights, Klaviyo can re-engage that visitor like they never left.
Their behavior, preferences, and past interactions are back in play, ready for personalized marketing.
Step 4: Trigger Targeted Emails or Campaigns
With Signal’s data, you can trigger campaigns tailored to their actions.
- Abandoned cart email? Done.
- A personalized product recommendation? Easy.
- A timely promo that speaks to their browsing history? You got it.
Why This Tactic Gets Overlooked
Marketers assume Klaviyo’s built-in tracking is “good enough” but that 7-day cookie expiration creates a major gap. Most brands don’t realize how much valuable traffic they’re losing because they don’t know these visitors are returning.
By extending Klaviyo’s reach, Signal makes re-signaling a powerful, yet often ignored, tactic.

The Benefits of Re-Signaling Your Klaviyo Return Visitors
Let me be clear, re-signaling isn’t just a “nice-to-have” tactic. It is a huge opportunity that most businesses don’t even know exists.
Here’s what you unlock when you bring Signal into your Klaviyo strategy:
1. Boost Conversions
Return visitors aren’t just browsing. They’re back because they’re interested.
Re-signaling these contacts makes sure you catch them at the right moment with the right message, giving you the best shot at converting.
Example: A customer browses your skincare line but doesn’t buy. Two weeks later, they return. Signal recognizes them, syncs with Klaviyo, and triggers a personalized email featuring the exact product they viewed, along with a limited-time discount. Sale made.
2. Improve Segmentation
Stop lumping returning visitors in with cold traffic!
Re-signaling lets you add these high-intent users to more precise audience segments. Whether it’s a “visited twice in 30 days” segment or a group of shoppers browsing a specific category, better data means better targeting.
Example: A visitor repeatedly checks out your running shoes category. Signal syncs this behavior, and Klaviyo adds them to a “running enthusiasts” segment. You then send them a campaign showcasing your new trail runners. Engagement skyrockets.
3. Increase Retention
Customers don’t always buy on the first visit or even the second. With Signal, you stay on their radar, reminding them why they came to you in the first place.
Example: A returning customer checks out your subscription page but doesn’t commit. Signal flags this activity, and Klaviyo sends them an email breaking down the benefits of subscribing, paired with a 10% off offer. They’re back in the game.
4. Optimize Ad Spend
Reaching warm audiences costs less and converts better than spraying ads at cold traffic. Signal ensures you’re spending your budget where it matters – on people who’ve already shown interest and are ready to take action.
Example: Instead of targeting a general retargeting pool, you use Signal to focus your Meta Ads on returning visitors who recently viewed your high-ticket items. The result? A higher ROAS (return on ad spend) with less wasted budget.
5. Enhance Lifecycle Marketing
Re-signaling fuels your lifecycle campaigns with fresh, relevant data. By keeping track of return visitors, you can craft messaging that aligns perfectly with where they are in their customer journey.
Example: A visitor who returned to your site after viewing baby gear gets synced into a Klaviyo flow tailored for new parents. Over time, they receive a series of helpful content, product suggestions, and time-sensitive offers that lead to a big purchase—and keep them coming back.
The takeaway? Re-signaling isn’t just about spotting return visitors. It’s about sharper targeting, stronger customer relationships, and giving your ROI an extra oomph.
