Popups and forms you can ask for

Each example comes with the prompt a merchant would type.

add an exit-intent email popup “Add an exit-intent popup that fires when the user moves their cursor toward the browser's close button (desktop) or scrolls quickly back up (mobile). Offer 10% off first order in exchange for email. Show once per visitor per 7 days.” See the example add a newsletter footer block “Replace the basic footer newsletter signup with a richer block: clear incentive (10% off first order), email input with inline validation, single-tap submit, success state with code, and a tiny privacy line. Submit to Klaviyo.” See the example build a welcome offer landing page “Build a welcome offer page: hero with "Welcome — 20% off your first order" headline, simple email capture, instant discount code on submit, 6 bestseller products to apply it to, and a "How to use your code" section.” See the example build a coming-soon waitlist page “Build a coming-soon page at /pages/coming-soon: 'Something Big is Coming' hero with subtle product teaser, countdown to launch date, email signup for exclusive early access (24h before public), waitlist member count for social proof, and FAQs.” See the example build a wholesale application page “Build a wholesale application page. 4-step application form with eligibility filter. Show sample pricing after approval.” See the example capture UTMs in lead forms “Capture UTM parameters on all lead forms and pass them to Klaviyo as custom properties.” See the example

It doesn’t stop at launch

Fudge tracks who signs up and what they buy, and suggests changes to the offer, the timing or the pages.

What Fudge tracks

Views and sign-up rate
Sign-ups by page and device
Orders from new subscribers

Helps with Conversion

Fudge suggests Nordhem Living

The popup gets twice the sign-up rate on product pages, and those subscribers buy just as often as the rest. Try showing it later on the homepage, after 30 seconds.

Shopify popup questions

Have your own questions?

Does it work with Klaviyo?

Yes. Ask Fudge to connect Klaviyo and choose a list. Sign-ups arrive with the page and the offer they came from, and follow your list’s consent settings, including double opt-in.

Does Fudge create the discount code?

Yes. Fudge creates the discount in Shopify, and the popup shows the code once someone signs up. If you’d rather send it by email, Klaviyo can deliver it instead.

Can I control when the popup shows?

Yes: after a delay, on scroll, on exit intent, on specific pages, for new or returning visitors, and on mobile or desktop. Phones have no cursor to track, so on mobile, exit intent means a quick scroll back up or a return from another tab.

Will it annoy shoppers?

You decide how often it appears. Fudge suggests sensible limits, like once per visitor, and hides it from people who have already signed up.

What other forms can Fudge build?

Waitlists, back-in-stock sign-ups for your Klaviyo flows, wholesale applications, contact forms and quote requests.
