A fullscreen, multi-step popup with a mystery discount lifted CraftMystic's email sign-up rate from 1.36% to 16.67% in a three-week A/B test. OptiMonk ran it for the crystal and spiritual goods store and published it as a case study. Many things changed at once, including the popup tool, size, offer and flow, so the result belongs to the whole package.

## Result

**signups 1.36% to 16.67%**

- Email sign-up rate: 1.36% to 16.67%, reported as +1,125%.
- Order conversion: 1.75% to 1.82%, about +4%. This gap is small and no significance is given, so treat it as uncertain.
- The test ran for three weeks. Sample size is not shared.

## Control

A basic sign-up popup from another tool, theMarketer, with two fields and a dropdown asking for the visitor's zodiac sign.

## Variant

A fullscreen popup in steps: pick your zodiac sign, enter your email for a mystery discount, then see personalized product picks. It showed on the homepage to non-subscribers after 5 seconds, at most twice.

## Why it likely won (our reading)

- Asking one thing per step feels lighter than a form with several fields.
- A mystery discount adds curiosity, which gives people a reason to finish.
- A fullscreen popup is hard to miss, unlike a small form.
- Starting with the zodiac question fits this audience, so the first click feels like fun, not work.

## Caveats

This was a bundled change: the tool, size, offer and flow all changed together, so no single element can take credit. Results are vendor-reported, with no sample size or confidence level shared.

## How to run this test

- Hypothesis: If we replace a basic sign-up form with a fullscreen, step-by-step popup that opens with an easy question and offers a mystery discount, then email sign-ups will rise because each step asks for little and curiosity pulls visitors through.
- Primary metric: Email sign-up rate
- Guardrail: Order conversion rate
- Guardrail: Homepage bounce rate
- Guardrail: Discount cost per order
- Who should test it: Stores with a niche audience and a fun question to open with, like style, skin type or zodiac sign. If your list is already growing well, or a fullscreen popup clashes with your brand, test a smaller format first.
