Popup showing the viewed product with 10% off: +55% subscribers

WinnerBefore/after, not a split testProduct page · 2026-03

Replacing generic sign-up offers with a popup that showed the exact product being viewed, with 10% off that product, lifted Whiskynet's subscribers by 55% and purchases by 6.6%.

OptiMonk ran this for the spirits retailer and published it as a case study.

It was a before/after result, not a split test.

Generic sign-up offer becomes a popup featuring the viewed product at 10% off.

Simplified mockup drawn by LiftArchive from the shared screenshots.

Control

Product pages used generic sign-up offers, such as a standard newsletter popup.

Variant

An AI-built popup showed the product the visitor was viewing, such as a specific gin, with a 10% discount on that item. The tool made a matching popup for each of more than 1,000 products.

Why it likely won

Our reading of the result, not the practitioner's claim.

  • Showing the item already on screen makes the offer feel like part of the visit, not an interruption.
  • A discount on the exact product is easier to value than a general store-wide code.
  • Premium spirits buyers often compare before buying, so a timely offer on the item in view can tip the choice.
  • The bigger gain in subscribers than purchases suggests many people signed up but did not buy right away.

Caveats: This was a before/after result with no stated comparison basis, sample size or duration. Results are vendor-reported, and an AI tool from the vendor made the popups.

How to run this test on your store

Hypothesis
If we replace our generic sign-up popup with one that shows the product being viewed and a discount on it, then more visitors will subscribe and buy because the offer matches what they already want.
Primary metric
Email sign-up rate
Guardrails
  • Purchase conversion rate
  • Discount cost per order
  • Revenue per visitor
Who should test it
Stores with large catalogs and lots of traffic landing straight on product pages, such as from ads. Stores with a few products can build these popups by hand, and stores that avoid discounts should test a non-discount version.

Questions

What is a product-matched popup?

It is a popup that shows the item the visitor is looking at and makes an offer on it.

Tools can generate one for every product automatically.

Is a product-specific discount better than a sitewide one?

Here it lifted subscribers by 55% over generic offers.

It was a before/after comparison, so test it on your own traffic.

Should I change popups by category too?

Whiskynet also tailored popups on category pages, which added 19.1% more subscribers.

Tailor them to whatever the visitor is browsing.
