Two-step yes/no popup, same 15% offer: +76% email sign-ups
Test run byOptiMonkTesting and CRO tool
Commentary byLiftArchiveOur analysis, not theirsTurning a one-step 15% off popup into a two-step popup that asks a yes/no question first raised illCurrency's email sign-up rate by 76% overall.
OptiMonk ran it for the sneaker-matching streetwear brand and published it as a case study.
This compares the old popup with the new one, not two versions running at once.
- Mobile email sign-up rate: 3.83% to 6.75%.
- Desktop email sign-up rate: 1.04% to 1.83%.
- Overall sign-up rate: +76%, as reported.
- Sales: about 200 extra orders and nearly $18,000, credited partly to the bestseller pick. The period this covers is not stated.
The change
The same offer, now asked as a yes/no question before the email field.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
A one-step Klaviyo popup offering 15% off in exchange for an email address.
Variant
The same 15% offer split into two steps: first the question "Would you like 15% off?", then the email field after a yes. The thank-you step also showed a bestseller under the line "Today's most wanted."
Why it likely won
Our reading of the result, not the practitioner's claim.
- A yes/no question asks for one click, not an email. Once people say yes, they are more likely to finish.
- Keeping the offer the same means the gain came from how it was presented.
- A bestseller on the thank-you step gives new subscribers a product to use their code on.
Caveats: This was a before-and-after comparison, not a split test, and the popup tool changed too. The old popup was measured over 30 days, but the new period's length, and whether the $18,000 is monthly, are not stated.

How to run this test on your store
- Hypothesis
- If we ask a simple yes/no question before showing the email field, while keeping the same discount, then more visitors will sign up because a small first commitment makes the next step easier.
- Primary metric
- Email sign-up rate
- Guardrails
- Orders from new subscribers
- Unsubscribe rate in the first 30 days
- Popup close rate
- Who should test it
- Stores that already run a discount popup and want more sign-ups without raising the offer. If your popup already converts well on mobile, the gain may be smaller.
Questions
What is a two-step popup?
It asks a simple question first, usually yes or no, and only shows the email field after a yes.
The first click is easy, which can make people more likely to finish.
Do I need a bigger discount to get more email sign-ups?
Not always. illCurrency kept the same 15% offer and still grew sign-ups by changing how it was asked.
