Exit Intent Popups: How to Save Shoppers Before They Leave

Most popups interrupt. An exit intent popup does the opposite. It waits until the shopper has already decided to leave, and only then makes one last offer.

That makes it the most polite popup you can run, and in our data, one of the strongest.

Data note: Figures come from aggregated, anonymous PopupBoost data, February to November 2026. The exit intent sample is small, so we flag where results are early.

How exit intent works

On desktop, the popup watches the mouse. When the cursor moves fast toward the top of the browser, toward the tabs, the back button or the address bar, the popup appears.

The visitor has not left yet. They were about to. So the popup does not block anything they were trying to do. It just asks one more question before they go.

Why it matters for Shopify stores

Most visitors leave without buying. Baymard Institute puts the average documented cart abandonment rate at 70.22%, based on 50 studies. And that only counts people who added something to the cart. Far more visitors leave before getting that far.

Every one of those exits is a visitor you paid for, through ads, content or time, who leaves with nothing. Exit intent gives you one more chance to turn that visit into an email or an order.

What our data shows

Only three exit intent campaigns in PopupBoost have enough traffic to measure, so take these numbers as an early signal:

• Median engagement for exit intent: 11.1%
• Median engagement for time delay campaigns: 7.9%

When we pool all exit intent views together, the result is even clearer: 13.3 tracked orders per 1,000 popup views, compared with 5.6 for time delay campaigns.

That gap makes sense. Exit intent only reaches shoppers who were on the site long enough to start leaving, and the offer arrives at a moment when it does not interrupt anything.

The catch: it is a desktop tool

Exit intent needs a cursor. Phones do not have one. In a recent sample, 80% of popup views came from mobile and only 19% from desktop.

So exit intent covers a minority of your traffic. It works best as a second trigger next to your main popup, not as your only one.

How to cover mobile visitors

On mobile, use what you have:

1. An early time trigger. Show the main offer within the first seconds, when mobile shoppers decide whether to stay. Our popup timing data shows that early popups get the most engagement.
2. A scroll trigger. Fire the popup after the shopper has scrolled part of the page and shown interest.
3. A floating teaser. If they close the popup, a small button stays on screen. They can reopen the offer when they are ready, which is the mobile version of a second chance.
4. Cart-based targeting. Show an offer to shoppers whose cart is in a certain range. See reducing cart abandonment with targeted popups.

What to offer on exit

The visitor has already decided to go. A soft "Join our newsletter" will not change their mind. The offer must answer the reason they are leaving.

• Price doubts: a discount slightly bigger than your welcome offer.
• Shipping costs: free shipping. It redeemed at 15.0% in our data, the highest of any prize type.
• Not ready yet: "Send me my cart" or "Save 10% for later", which captures the email for a reminder.
• Just browsing: a game. A spin wheel turns a quiet exit into a moment of play.

Exit intent copy that works

Keep it short and direct. The shopper's attention is already somewhere else.

• "Wait! Spin before you go."
• "Leaving already? Here is free shipping on your first order."
• "Your cart is waiting. Take 10% off if you finish today."

Avoid guilt and pressure. "Are you sure you want to miss out?" makes the brand feel desperate.

Setup checklist

1. Create an exit intent campaign or add exit intent as an extra trigger to your main campaign.
2. Use a stronger offer than your welcome popup, or the same game with better odds.
3. Limit how often it appears, for example once per day, and avoid showing it to people who already signed up.
4. Exclude the checkout pages.
5. Connect it to your email tool, so a shopper who leaves their email gets a reminder. See syncing popup signups with Klaviyo and Shopify Email.

Mistakes to avoid

• Making it the only trigger. You miss almost all mobile traffic.
• Using the same offer as the welcome popup. If they ignored it once, they will ignore it again.
• Firing on every page view. A daily frequency limit is enough.
• A slow popup. If it takes a second to load, the visitor is already gone.

Your next step

If you run only a time-delay popup today, add exit intent as a second trigger with a stronger prize for desktop visitors. Keep your main popup as it is for mobile.

Then compare results after two weeks. If exit intent brings in orders at anything close to the rate in our data, it will be one of the cheapest wins on your store. For the full popup strategy, read our complete guide to Shopify popups.

Frequently asked questions

What is an exit intent popup?

An exit intent popup appears when a visitor shows signs of leaving the page, usually when the mouse moves quickly toward the browser's tab bar or address bar. It gives you one last chance to make an offer before the visit ends.

Do exit intent popups work on mobile?

Not in the classic way, because there is no cursor on a phone. On mobile, stores usually rely on a time or scroll trigger plus a floating teaser that stays on screen, so shoppers can reopen the offer when they want.

What should an exit intent popup offer?

Something stronger or more direct than your welcome popup, because the visitor has already decided to leave. Free shipping, a slightly bigger discount or a reminder of what is in their cart all work well.

Are exit intent popups annoying?

Less than most popups, because they do not interrupt someone who is browsing. They appear only when the visitor is already on the way out, and they should have a frequency limit, such as once per day.
