Nudge Customers to Unlock Free Shipping

Motivate customers to add just a little more by showing how close they are to free shipping

Why it works

Free shipping is one of the strongest motivators for completing a purchase. By showing how much more a shopper needs to spend to qualify and suggesting what to add, you create a natural upsell moment.

It removes friction, increases average order value, and feels like a win for the customer.

Turn on-site behavior into targeted messages that drive more sales.

How to implement it

1. Adjust the Design

Update the image, fonts, and colors to reflect your brand. Be sure to check both desktop and mobile views for a consistent experience.

Customize fonts, colors, and layout for your free shipping popup

2. Add Merge Tags

Click Merge tags and select SiteData.

If your data layer includes a cart value variable, you can display how much is left to unlock free shipping. Use the following formula: {{=SUM(SITEDATA(cart_total), – 500)*-1}}

This shows the remaining amount toward your shipping threshold, like €500.

Add merge tags to dynamically show cart progress in the free shipping popup

3. Add a Destination Link

Set the CTA to guide visitors where you want them to go such as your bestsellers, sale page, or new arrivals.

Set a destination link to help users reach the free shipping threshold

4. Choose the Trigger

On desktop, use exit-intent to catch potential customers before they leave.

On mobile, disable the teaser to trigger automatically, or enable it so users can tap to open the form.

Set popup trigger to exit-intent on desktop and tap or auto on mobile

5. Target the Right Pages

Decide if the campaign should appear across your site or only in the cart.

Target the free shipping popup to cart pages or sitewide

6. Show Campaigns Based on Basket Size

Use SiteData to show this campaign only to visitors close to your free shipping threshold.

You’ll need to:

  • Set up a trigger in your tag manager (like Google Tag Manager).
  • Add the variable that tracks cart value (e.g. BasketValue).
  • Define when the campaign should show (e.g. between 250–499).

Please note: BasketValue variables may be named differently in your system. Be sure to match it exactly.

Show free shipping popup only to users near the threshold using basket value

Once your campaign is ready, save and activate it.

FAQ

Free shipping removes one of the biggest barriers to completing a purchase: unexpected costs. During Black Friday and other high-volume sales events, it becomes even more powerful, helping reduce cart abandonment and increase conversion rates when urgency is already high.

By showing how close a customer is to unlocking free shipping, the popup motivates them to add more to their cart. This simple nudge increases both conversions and AOV by turning a static cart into an active goal.

Set a clear minimum order threshold, like 500, to protect margins. Use urgency with limited-time offers, especially around events like Black Friday, and direct users to product collections that help them reach the threshold. The popup does all of this dynamically.

Start with the Free Shipping template inside your Sleeknote account. Then, adjust the copy and design, insert the merge tag to calculate the remaining amount, choose your trigger and targeting rules, and set a CTA that guides customers to relevant products.

You can edit fonts, colors, images, and buttons directly in the Sleeknote editor. Make sure to preview the design on both desktop and mobile before you publish.

Use a formula like {{=SUM(SITEDATA(cart_total), – 500)*-1}} to calculate and display the amount left to unlock free shipping. It updates in real time as customers add or remove items from their cart.

The CTA should lead customers to a page where they can easily add more to their cart, such as a sale page, product collection, or new arrivals. This helps them reach the free shipping threshold faster.

Use exit-intent triggers on desktop to recover abandoning carts. On mobile, either enable or disable the teaser depending on what gives the best visibility without disrupting the user experience.

Set up custom targeting using cart value ranges, like 250 to 499. This way, the popup only shows when it’s relevant, nudging customers who are close to the free shipping goal without distracting those who are far off.

No. Sleeknote popups load asynchronously and won’t slow down your site, even during traffic spikes like Black Friday or Cyber Monday.

Keep the copy clear and actionable, highlight the benefit, like “You’re just 100 away from free shipping,” and use a strong CTA. Match the design to your brand and seasonal theme to stay relevant and engaging.

A/B test different versions of your popup by trying new copy, designs, CTAs, and triggers. Track which combination leads to the highest AOV, conversion rate, or free shipping unlocks.

Check your cart merge tag, targeting rules, and trigger settings. Make sure the variable name, like cart_total, matches what’s being used in your setup and is available on the site.

Track views, conversion rate, AOV lift, and the number of orders that meet the free shipping threshold after popup interaction. These insights help you fine-tune the campaign for better results.
