Before You Go vs Klaviyo Forms

This comparison comes up because Klaviyo is the most-installed marketing tool on Shopify by a wide margin and Klaviyo Forms is the popup product attached to it — so when a merchant types "best Shopify exit-intent" into a search box, Klaviyo's brand size puts it in the consideration set whether or not it's the right fit. The honest read is that Klaviyo Forms and Before You Go are barely competitors at all. They solve different problems for different moments and most healthy stores run both. The rest of this page explains why.

What Klaviyo Forms does

Klaviyo Forms is the on-site popup, embed, and flyout product inside the Klaviyo platform. It's not a standalone product anymore — every Klaviyo plan (including the free one for up to 250 active profiles) includes Forms with no separate charge or feature gate. The builder supports modal popups, embedded inline forms, full-page takeovers, and side flyouts with triggers on exit intent, scroll depth, time on page, or specific URLs. Forms collect emails, phone numbers, and consent, then drop the contact straight into a Klaviyo segment where a flow can fire on it.

The point of Forms is the form. It's the on-ramp into Klaviyo's actual product, which is the email and SMS marketing platform — the segmentation engine, the abandoned-cart and browse-abandonment flows, the campaign scheduler, the deliverability infrastructure. That's where the value lives. Forms are the surface that captures the contact so the rest of Klaviyo has someone to send to.

Pricing is straightforward and contact-based. Free up to 250 active profiles. Email-only paid plans start at $45/month for 15K emails to 500 profiles and scale up by profile count. Email + Mobile Messages bundles start at $80/month for the same 15K emails plus 3,750 SMS or WhatsApp credits. SMS uses a credit system that varies by destination country. There's no separate "Forms-only" plan — if a store wants Klaviyo Forms it gets the whole Klaviyo platform, which is most of the appeal.

What Before You Go does differently

Before You Go isn't a popup tool, isn't a form, doesn't capture emails. The product is a single recovery moment: when a visitor on a product page is about to leave, the app renders a full page of recommendations inside the store's own theme — same header, footer, type, URL — populated from a purchase-affinity engine that runs nightly across the store's catalog. Co-views, co-clicks, co-purchases, and content similarity get blended into one score per product pair. The visitor sees what looks like a category page that quietly assembled itself around what similar visitors actually bought.

Attribution is session-based click attribution — the visitor has to click a recommended product, the order has to land in the same session, otherwise it doesn't count. Pricing is flat: $0, $29, $99 per month. Native installs on Shopify and Shopware. There is no email program, no SMS pipeline, no contact list to grow. The job is product discovery in the moment, not list growth over time.

So the comparison is mostly category confusion. Klaviyo Forms is a list-growth tool inside an email and SMS platform. Before You Go is a discovery recovery page. Both happen to fire when a visitor is about to leave a page, which is where the surface overlap ends.

When Klaviyo Forms is the right choice

Whenever the storefront's bottleneck is the email and SMS program — whether the gap is "we have no list," "we have a list but no flows running on it," or "our flows are configured but the welcome popup is converting badly." Klaviyo Forms is the right surface for any of those, because the form is the entry point into a marketing system that actually runs the recovery, the welcome series, the browse abandonment, the lifecycle nurture. None of that exists in Before You Go and none of it should — they're different products.

Klaviyo Forms also fits stores that already pay for Klaviyo (which is most stores past about $500K in revenue) because Forms costs nothing extra on top of the existing subscription. Spinning up another vendor for popups when the platform that's already installed includes them is rarely the right move.

And it's the right pick anywhere the actual conversion lever is the email or SMS that fires after the form, not the form itself. A discount popup that captures an email and triggers a five-touch flow is doing most of its work in the flow, not at the popup. Klaviyo is built for the flow.

When Before You Go is the right choice

When the visitor's problem on the way out is that they couldn't find the right product, not that they didn't sign up for the newsletter. A visitor who's seen one PDP, decided it isn't quite right, and is reaching for the back button isn't usually short on convincing — they're short on alternatives. A coupon popup or a "10% off your first order" form solves the wrong job. A full page of products the store actually sells, ranked by what similar visitors bought, is closer to what's missing.

Also the right pick when the brand is at a price point or aesthetic where popup chrome reads as cheap, and when the storefront already has a working email program — the recovery page is for the visitors the email won't reach because no email exists for them yet. And it's the right pick for the Shopware merchants in this conversation: Klaviyo's Shopware integration exists but is shallower than the Shopify one, and Before You Go's Shopware install is native to the storefront's template engine.

Side-by-side

What I'd do

If the storefront doesn't have Klaviyo yet and the email program is underbuilt, install Klaviyo. The popup is the cheapest part of the value, and Klaviyo Forms is included. If the storefront already has Klaviyo running well and the question is "what do we do about visitors who leave a single PDP without ever being captured," Klaviyo doesn't have a great answer for that — they never gave you an email, so the flows never fire. That's where Before You Go fits, and it doesn't replace anything Klaviyo is already doing. Most stores past a certain size end up with both, sitting in different parts of the funnel.
