Turning 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.

## Result

**+76% email sign-ups**

- 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.

## 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)

- 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

- 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
- Guardrail: Orders from new subscribers
- Guardrail: Unsubscribe rate in the first 30 days
- Guardrail: 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.
