How to Make Better, High-Converting Klaviyo Popups [2026]

Not completely satisfied with the popup signup forms in Klaviyo?

Is your popup strategy has become more sophisticated than Klaviyo's signup form builder was designed to handle?

If you want to:

• Use AI popups for product recommendations and AI cart recovery

• A/B test with control groups to measure true incrementality

• Track real attributed revenue and AOV lift, not just signups

• Use custom CSS and have more design freedom to create popups that match your brand...

...then consider a dedicated Shopify popup platform with a deep Klaviyo integration like Wisepops (4.8 stars on Shopify App Store).

The four limitations of Klaviyo signup forms we hear about most

No AI product recommendations

Personalized picks, "Others also viewed," "Our bestsellers, "You recently viewed," and others—you can show all of these at the right moment thanks to targeting features in dedicated ecommerce popup platforms. Klaviyo signups forms can't be used for this purpose, so there's a chance that you're leaving a lot of revenue on the table.

Examples:

Left: Nutrimuscle shows bestsellers in the welcome popup after visitors subscribe (7K emails captured 23,970 conversions attributed).

Right: Pierre Hardy's personalized product recommendations in the exit campaign helped convert 565 visitors.

No dedicated cart recovery campaigns (including AI-based)

Wisepops has multiple dedicated cart recovery popups based on abandonment signals, including AI. Klaviyo only has one exit-intent campaign in the template library for this goal.

Example:

Limited targeting options for personalization

For sophisticated ecommerce strategies, this is a real constraint. What you can't easily do: Target based on Shopify customer data (cart value, customer lifetime value, product tags) or create logic like "show this offer only to people visiting my website for the second time that have between $20-50 in their cart."

No A/B testing with control groups

Klaviyo lets you A/B test popups, but you can't create a true control group, eg. visitors who see nothing so you can measure real incrementality. This means you can test copy variations, but you can't answer the question: "What if I hadn't shown this popup at all? Would the customer have converted anyway?"

Wisepops includes control groups in A/B tests, which gives you actual ROI measurement, not just relative performance:

The popup design constraints

Brands with meticulous design standards tell us the same thing: Klaviyo's form editor limits what they can achieve visually.

If your vision requires something beyond the standard form layout, such as custom CSS styling, unconventional layouts, it won't be possible in Klaviyo.

How to create a Klaviyo popup (multi-step email capture campaign with product recommendations)

Let's make a lead generation popup that also introduces customers to bestsellers to drive immediate product discovery and purchase.

Follow these steps:

1. Start a new campaign

2. Select a multi-step template

3. Customize design and copy

4. Configure Klaviyo integration

5. Set display and targeting rules

6. Publish and track performance

In this tutorial, I'm using Wisepops (rated 4.8 on Shopify). The platform offers native Klaviyo integration and subscriber segment targeting, AI cart recovery and product recommendations.

Step 1: Create a new campaign

Navigate to New popup campaign in the Popups main menu:

Step 2: Choose a template

Choose "Popup" as your format. We'll use a Shopify-optimized template called "Multi-step Email Capture with Product Recommendations," the same campaign format used successfully by brands like Nutrimuscle.

Search for this template in the template library or browse by use case in the left menu:

Step 3: Customize design and copy

Wisepops provides granular design control that offers more flexibility than Klaviyo's.

Start by modifying:

• Typography (custom fonts, weights, sizes, letter spacing)

• Layout structure (multi-column grids, custom spacing)

• Animation timing and effects

• Mobile-specific designs

• Advanced CSS for precise brand matching

Step 4: Configure Klaviyo integration

Click the email signup field and navigate to the Sync tab in the left panel. There, choose Klaviyo from available integrations and authenticate your account.

Step 5: Add product recommendations and discount code

Here, we add the discount we promised.

Select the discount block and choose a public discount (one that can be used by multiple customers) or a unique one.

If you integrated Wisepops with Shopify, you'll be able to easily create and add your unique discounts, too.

When you add your code, choose what happens when a visitor clicks it (copy to clipboard or apply to the cart):

Also, we'll display personalized product recommendations to drive immediate purchase consideration. This makes your popup a revenue-generating tool.

Click the product recommendation block and configure:

• Recommendation type (bestsellers, new arrivals, specific collections)

• Number of products to display (3-4 typically performs best)

• Product filtering (include/exclude specific SKUs or collections)

• Dynamic pricing display

• Add-to-cart functionality

Learn how to manage recommendations.

Step 6: Set display and targeting rules

Navigate to Display rules > Triggers.

Research indicates that delaying popup appearance by 10+ seconds improves conversion rates by up to 30%.

Consider these triggers based on strong engagement signals:

• Trigger: on landing

• Time delay: 10-15 seconds minimum

• Page views: After one page (demonstrates real interest)

Audience targeting:

In Display rules > Audience, define who sees your popup:

• New visitors only

• Traffic source filtering (paid vs organic)

• Device-specific rules (mobile vs desktop optimization)

Also, Wisepops can target your Klaviyo lists, eliminating redundant signup requests and improving message personalization.

Go to Display rules > Advanced to choose a subscriber segment from your Klaviyo account (the existing list members are excluded by default of course):

Step 7: Publish your campaign

Click Done editing, then Publish in the campaign overview.

If you've installed the Wisepops script on your ecommerce store, the popup deploys immediately and starts tracking your goal and revenue.

You'll see the basic performance stats in the dash:
