A Klaviyo popup alternative for the moment before the abandoned checkout email
Klaviyo’s popup is a sign-up form: it feeds the email and SMS platform, and its cart recovery is the abandoned-checkout flow that goes out after the shopper leaves. Resparq is not an alternative to Klaviyo. It is the alternative to using Klaviyo’s popup as your cart recovery: one offer on the page, to a shopper with items in the cart as they go to leave, with nothing to sign up for. Keep Klaviyo. Put Resparq in front of it.
An email platform with a sign-up popup, and a popup with no sign-up
Klaviyo
Shopify App Store listing “Klaviyo: Email Marketing & SMS”, read October 15, 2026
Klaviyo’s listing leads with “Email marketing, SMS, & WhatsApp that turn messages into sales”. Its guided setup for a new store is “sign-up form, welcome email, and abandoned-checkout flow”: the popup collects the address, the welcome email uses it, and the abandoned-checkout flow is the cart recovery, by email, after the shopper has left checkout.
Pricing is by contacts and credits: free for up to 250 email contacts and 150 SMS credits, then Email from $20 a month for 251 to 500 contacts and SMS from $15 a month for 1,250 credits, rising as the list grows. The listing shows 4.7 stars across 3,381 reviews.
Resparq
What the app does, from the code it ships
Resparq runs on your storefront, on product and cart pages, and when a shopper with items in the cart goes to leave, it shows one modal: an offer, or in AI mode sometimes a reminder with no discount. In Manual mode it is the offer you wrote. In Guided and AI mode the modal is chosen per shopper from signals like cart value, time on site, device, traffic source and past abandonment. Accept the offer and a single-use code is applied on the way to checkout.
The popup never asks for an email address. Starter is free, Pro is $50 a month flat and Enterprise is $150, with no overage and no commission on recovered orders. In Guided mode and AI mode on Pro and Enterprise, 10% of eligible shoppers are held out and never shown a modal, so the dashboard reports lift against that group once it clears 30 visitors.
Klaviyo’s popup and flow, and Resparq, compared
Klaviyo’s column covers the sign-up popup and the abandoned-checkout flow as the listing describes them; Resparq’s column describes what the app does.
Klaviyo after they leave, Resparq before
Klaviyo’s cart recovery works a different moment: the abandoned-checkout flow sends messages after the shopper is gone. Resparq works on-site, while the shopper is still there, and the popup never asks for an email address, so there is nothing to sync and no flow to rebuild. A shopper who ignores the modal and leaves still gets whatever email Klaviyo sends, if it can identify them.
Where stores go wrong is using the Klaviyo sign-up popup as the cart recovery. A sign-up form asks for an address, so the shopper who was leaving with a full cart is asked to type first. Resparq’s modal asks for nothing, shows the offer, and applies the code on the way to checkout.
A shopper who accepts and buys is an order. A shopper who leaves anyway is Klaviyo’s, exactly as before: the flow fires for the shoppers it can identify, and Shopify’s abandoned checkout email still goes out for the ones who reached checkout with contact details.

Yes. Klaviyo’s abandoned-checkout flow works a different moment: it sends messages after the shopper is gone. Resparq works on-site, while the shopper is still there, and the popup never asks for an email address, so there is nothing to sync and no flow to rebuild. A shopper who ignores the modal and leaves still gets whatever email your other app sends, if it can identify them.
Only if you no longer want to grow the list. The sign-up form is how Klaviyo gets addresses, and Resparq will not replace that; the popup never asks for an email address. What you can stop doing is treating the sign-up form as cart recovery. If another app has a popup open, Resparq waits rather than stacking, so the two can share a store.
No, it runs before it. The flow goes out after a shopper Klaviyo can identify has left; Resparq acts on the store itself, in the moment the shopper is about to leave, and needs no address. Keep the flow on. Resparq handles the shoppers who added to cart and were leaving without typing anything, a group no email flow can reach unless it already knows them.
Measure against a holdout. In Guided mode and AI mode on Pro and Enterprise, 10% of eligible shoppers are held out and never shown a modal, so the dashboard reports lift against that group once it clears 30 visitors. Starter runs in Manual mode with no holdout, so it reports conversions and attributed revenue rather than lift. Recovered revenue on its own always includes sales that would have happened anyway.
It works on the storefront, on product and cart pages, while the shopper is still there. On desktop the exit trigger watches for the cursor leaving the page, and in Guided and AI mode a variant can also fire on a timer on the page, on any device. On mobile there is no cursor, so Guided mode and AI mode use that timer, starting once the cart has items, and, for exit-intent variants, the shopper coming back to the tab after switching away. Manual mode on any plan can switch on a time-delay trigger that fires once the cart has items. The popup never asks for an email address, and an accepted discount is applied through Shopify’s discount link on the way to checkout.
No code. Install from the Shopify App Store, switch on the Resparq app embed in the theme editor, then switch the modal on from the Resparq dashboard. Two toggles, and it works with any Shopify theme. The scripts load deferred, after the page has rendered.
Starter is free: Manual mode, up to 1,000 impressions a month. Pro is $50 a month flat and adds Guided mode and AI mode. Enterprise is $150 a month for unlimited impressions and white-label modals. Paid plans include a 14-day free trial, with no setup fees and no commission on recovered orders.
