For most Shopify stores, the best popup app is the one built into your email platform: Omnisend if you want a cheaper all-in-one tool with spin-to-win and exit intent on every plan, or Klaviyo forms if you already send email through Klaviyo. Pick a standalone popup app like OptiMonk or Privy only when you need more targeting or A/B testing than your email tool gives you.
Whatever you pick, keep a popup running. In our database, removing an email popup cost one store 20.51% revenue per visitor.
Below we compare the main options using vendor docs, pricing pages and Shopify App Store reviews. We have not used these apps ourselves, so treat this as a research summary, not a hands-on test.
| App | Free plan | Paid from (as of November 2026) | Exit intent | Spin-to-win | Best for |
|---|---|---|---|---|---|
| Omnisend | Yes, 250 contacts, forms carry Omnisend branding | $16/month Standard | Yes, desktop and mobile | Yes, all plans | Small and mid stores that want email, SMS and popups in one tool |
| Klaviyo forms | Yes, 250 active profiles | $20/month email | Yes, desktop and mobile | Yes | Stores already on Klaviyo |
| Shopify Forms | Free app | Free | Yes | No game forms | New stores on Shopify Email |
| OptiMonk | Yes, 10,000 pageviews | $29/month Essential (monthly billing) | Yes, all plans | Yes, all plans | Stores that want advanced targeting and popup A/B tests |
| Privy | 15-day trial only | $24/month popups only | Yes | Yes | Stores that want popups plus simple email in one place |
Omnisend: the all-in-one pick for most stores
Omnisend is an email and SMS platform with popup forms built in. Its help center says the Wheel of Fortune (spin-to-win) block is available on all plans, and popups can trigger on time on page, scroll depth, page visits, exit intent on desktop and mobile, or custom triggers.
The pricing page lists a free plan for up to 250 contacts and 500 emails a month, with "Powered by Omnisend" branding on forms and emails. On the Shopify App Store listing, paid plans start at $16/month (Standard) and $59/month (Pro) as of November 2026, and the pricing page was showing a 30% discount on the first months when we checked.
The app has a 4.7-star rating from about 3,200 reviews on the Shopify App Store. Reviewers mostly praise easy setup and responsive support. One review flagged that list hygiene costs extra.
Downsides: the free plan's branding shows on your popups, and pricing grows with your contact list. Its popup targeting is solid for list building but lighter than a dedicated popup tool.
Not for: stores that are happy on Klaviyo and do not want to migrate flows, or large brands that need deep segmentation and custom reporting. Our Omnisend vs Klaviyo comparison covers that choice in detail.
Klaviyo forms: best if you already use Klaviyo
Klaviyo's sign-up forms are included with its email platform, and the pricing page lists web forms on the free plan (250 active profiles, 500 emails a month). On the Shopify App Store, paid plans start at $20/month for email and $15/month for SMS as of November 2026. The listing has a 4.7-star rating from about 3,400 reviews.
Forms support exit intent on desktop and mobile, plus a spin-to-win block. Klaviyo's spin-to-win guide says each wheel form needs an email or SMS consent field and must display on all devices, and it reminds you to check local sweepstakes laws.
The main reason to use Klaviyo forms is data. Every signup lands straight in the same profile that drives your welcome and cart abandonment emails, so there is no sync to break.
Downsides: Klaviyo bills on active profiles, and one App Store reviewer warned this can mean you pay for people you are not emailing. Public reviews also mention a learning curve.
Not for: small stores watching every dollar who only need a popup and a welcome email. Omnisend or Shopify Forms cost less at that stage.
Other popup apps worth a look
Shopify Forms
Shopify Forms is free and made by Shopify. It covers popup and inline forms, discount incentives, exit intent, and links into Shopify Email automations. It holds 4.5 stars from about 760 reviews.
Not for: stores that want spin-to-win or deep design control. Reviewers say it lacks customization and ask for quiz and game forms.
OptiMonk
OptiMonk is a standalone popup tool. As of November 2026 its free plan covers 10,000 pageviews a month on one domain, and paid plans run $29, $99 and $249 a month on monthly billing (about 25% less billed yearly). Exit intent, gamification and A/B testing are on all plans, with no OptiMonk branding.
Not for: stores that want one bill. You still need an email tool, and pricing climbs with pageviews, so high-traffic stores pay more even if the popup converts the same.
Privy
Privy sells a popups-only plan from $24/month for up to 10,000 pageviews, up to $1,140/month at 2.5 million pageviews, as of November 2026. Email plans start at $30/month. Spin-to-win, cart savers, exit intent and A/B testing are included. There is a 15-day trial but no free plan.
Not for: stores that want to start free, or stores already committed to Klaviyo or Omnisend, where you would be paying twice for forms.
Exit intent popups on Shopify
An exit intent popup shows when a visitor seems about to leave. On desktop, that is usually the cursor moving toward the browser bar. On mobile, there is no cursor, so apps use signals like a fast scroll up or the back button. Omnisend and Klaviyo both offer separate desktop and mobile exit triggers.
All five apps above support exit intent, so this alone should not decide your pick. What matters more is what the popup offers and who sees it.
- Use it as a second chance, not the first ask. A common setup is a timed welcome popup for new visitors and an exit popup only for people who closed it or never saw it.
- Exclude buyers and subscribers. Hide the popup for people already on your list and on checkout pages.
- Match the offer to the page. On the cart, a reminder about free shipping or a saved cart can work better than a generic discount. Our cart abandonment software guide covers tools for that moment.
- Be careful with fake urgency. Ruben at Tailored Commerce saw a countdown timer give about +10% CVR on a low-priced brand, stay flat on a high-priced brand, and lose 9% CVR on another. Timers in spin-to-win popups can go either way, so test them. See countdown timer tests for more.
What the popup tests in our database show
Most popup advice is opinion. Here is what real Shopify tests in LiftArchive found. You can browse all of them on our popup tests page.
@DaveDiederen@DaveDiederen
@kasper_dolk@DaveDiederenRemoving the email popup lost money
Dave Diederen tested removing a store's email popup. The version without it lost, at -20.51% revenue per visitor. The popup was earning its place, likely through the signups and first-order discounts it drove.
If your popup feels annoying, the data says to fix the timing or the offer before you delete it.
Popups that help shoppers, not just collect emails, also win
Dave Diederen saw +12.32% CVR when a store added a geo-detection popup asking international visitors to confirm their country and switch currency. That popup removed a doubt at the moment it mattered.
In another test, Dave Diederen tried two different upsell products in the add-to-cart popup on the product page, and the winner gave +7.80% revenue per visitor. What you put in a popup matters as much as having one. Our Shopify upsell apps roundup covers tools for that kind of popup.
Kasper Dolk ran a test that paired swipeable collection images with a retail-price comparison popup on the product page. The reported result, +€96,350 revenue at 97% confidence, is for the swipeable images, so it does not isolate the popup. It shows how practitioners use popups to explain value, not only to ask for an email.
Discount size is worth testing too
Many popups lead with "10% off your first order". Ruben saw +28% RPV after adding a one-click 10% extra discount banner above the add-to-cart button. That was a banner, not a popup, but it shows how much a visible, easy discount can move revenue. Browse more pricing and discount tests before you set your popup offer.
How to test your own popup
Most popup apps can split traffic between two popup designs, which is fine for comparing signup rate. To measure revenue per visitor, as the tests above did, run the popup change through an A/B testing tool. Our list of Shopify A/B testing apps covers the options.
Judge the test on revenue per visitor, not signups. A bigger discount can grow your list while giving away margin on orders that would have happened anyway.
