Case Study: How a Fashion Store Grew Their Email List 3x in 90 Days with a Spin Wheel Popup

Store Background & Context

The store in this case study is a women's contemporary fashion brand operating on Shopify since 2022. They sell mid-range clothing priced between $45 and $180, targeting women aged 25-40 who value trend-forward styles at accessible price points. At the time of this case study, the store was generating approximately $85,000 per month in revenue with around 45,000 monthly visitors.

Their product catalog included approximately 320 active SKUs across dresses, tops, bottoms, outerwear, and accessories. They maintained an active social media presence on Instagram (42,000 followers) and TikTok (18,000 followers), which drove the majority of their traffic alongside paid advertising on Meta and Google.

The store had been using a standard static email popup for over a year. The popup offered 10% off in exchange for an email address and appeared after 15 seconds on site. While it captured some subscribers, the growth rate had plateued, and the team recognized that their email list was their most underutilized revenue channel.

Email marketing was handled through Klaviyo, with basic flows for welcome series, abandoned cart, and post-purchase follow-up. Despite having these automations in place, email accounted for only 12% of total revenue, well below the 20-30% benchmark for successful fashion brands.

The Challenge

The store faced several interconnected problems that were limiting their growth and profitability.

Stagnant email list growth. Their email list had grown from 6,500 to 8,200 subscribers over the previous six months, a rate of roughly 280 new subscribers per month. At that pace, reaching their goal of 25,000 subscribers would take over five years. With 45,000 monthly visitors, they were converting less than 1% of their traffic into email subscribers. The vast majority of first-time visitors were leaving without any way to re-engage them.

Low popup engagement. Their existing static popup had a 2.1% opt-in rate, meaning that for every 1,000 visitors who saw the popup, only 21 entered their email address. Industry benchmarks for fashion popups are 5-8% for static designs and 10-15% for gamified formats. Their popup was underperforming even by static popup standards, likely because visitors had become desensitized to the generic "10% off for your email" format that appears on virtually every fashion store.

High customer acquisition costs. The store was spending $32 per acquired customer through paid advertising. With an average order value of $78 and a gross margin of 55%, the $32 acquisition cost was consuming a significant portion of their profit. They needed a channel that could bring customers back without additional ad spend, and email was the obvious answer, but only if they could grow the list fast enough to make it meaningful.

Poor first-visit conversion rate. Only 1.2% of first-time visitors made a purchase, compared to 4.8% for returning visitors. This meant that 98.8% of new visitors left without buying. Without capturing their email, there was no way to bring them back. The store was essentially paying to acquire traffic through ads, losing 98.8% of it on the first visit, and having no mechanism to recapture those visitors without paying again.

Rising competition for attention. The women's contemporary fashion space on Shopify is intensely competitive. Shoppers routinely browse 3-5 stores before making a purchase decision. The store needed a way to make a memorable first impression and establish a connection with browsers who were comparing them against competitors.

Seasonal revenue volatility. The store experienced significant revenue drops between major shopping periods like Black Friday, holiday season, and summer sales. Without a large email list to drive demand during slower periods, they were heavily dependent on paid advertising to maintain baseline revenue. This created a costly and unsustainable cycle.

The Solution: EA Email Popup & Spin Wheel

After researching popup solutions and evaluating several options, the store chose EA Email Popup & Spin Wheel for several reasons: it offered gamified spin wheel functionality, it integrated natively with Klaviyo, it provided extensive targeting and trigger options, and it had a free plan that allowed them to test before committing financially.

Spin wheel configuration. The store designed their spin wheel with six prize segments, carefully calibrated to balance subscriber acquisition with margin protection. The prizes were distributed as follows:

• 10% off your order (35% probability) - The most common prize, still attractive enough to motivate a purchase while protecting margin.
• 15% off your order (25% probability) - The mid-tier prize that created a feeling of winning something above the minimum.
• Free shipping (20% probability) - High perceived value with relatively low actual cost, especially for orders that might have qualified for free shipping anyway.
• 20% off your order (10% probability) - A premium prize that felt genuinely exciting to win, driving higher conversion on the resulting discount code.
• $5 off your order (5% probability) - A smaller fixed-amount prize that served as a low-cost consolation option.
• 25% off your order (5% probability) - The jackpot prize. Rare enough to protect margins but exciting enough to generate word-of-mouth and social sharing.

Trigger and targeting rules. The store set up specific rules for when and to whom the spin wheel would appear. The popup was configured to trigger on exit intent for first-time visitors only. This meant it appeared when a new visitor moved their cursor toward the browser's close button or back button (on desktop) or started scrolling up rapidly (on mobile). Returning visitors and anyone who had already interacted with the popup were excluded.

Additionally, they excluded visitors who had arrived on the site with a discount code already applied (from influencer links or paid ads with promotional offers). This prevented the awkward situation of offering a second discount to someone who already had one, and it avoided discount stacking issues.

Design and branding. Rather than using a generic spin wheel design, the store customized the wheel's colors, fonts, and messaging to match their brand identity. The wheel used their brand's signature dusty rose and cream color palette. The headline read "Spin for Your Style Reward" rather than the generic "Spin to Win," and the subheading copy said "Every spin wins a prize. Enter your email to try your luck." This language was more aligned with their sophisticated brand positioning than typical gamification copy.

SMS dual opt-in. In addition to email capture, the popup included an optional SMS opt-in checkbox. The store did not require SMS signup, making it a frictionless addition. Approximately 38% of email subscribers also opted into SMS, giving the store a valuable second communication channel.

Discount code delivery. After spinning and winning, the subscriber received their discount code both on-screen and via an immediate confirmation email. The discount codes were set to expire in 72 hours, creating urgency to use them. Each code was unique and single-use, preventing sharing and abuse.

Klaviyo integration. All spin wheel subscribers were automatically tagged in Klaviyo with "spin-wheel-subscriber" and their specific prize (e.g., "won-15-percent"). This allowed the store to create a dedicated welcome flow for spin wheel subscribers that was different from their standard signup flow. The spin wheel welcome series acknowledged the prize won and then transitioned into brand storytelling and product education over the following two weeks.

Implementation Timeline

One of the most striking aspects of this case study is how quickly the solution was implemented and how rapidly results materialized.

Day 1: Installation and basic setup (45 minutes). The store owner installed EA Email Popup & Spin Wheel from the Shopify App Store. The initial setup involved selecting the spin wheel format, entering prize values and probabilities, and connecting the Klaviyo integration. The app's built-in templates made this process straightforward, even for someone with no design or development background.

Day 1-2: Design customization (30 minutes). The store's marketing manager customized the spin wheel colors, fonts, and copy to match the brand. They uploaded their logo to appear in the popup header and adjusted the background overlay opacity to ensure the popup felt premium rather than intrusive.

Day 2: Targeting configuration (15 minutes). Setting up the exit-intent trigger, first-time visitor targeting, and discount code exclusion rules. The store tested the popup in preview mode to verify it appeared correctly on both desktop and mobile devices.

Day 2: Klaviyo flow setup (30 minutes). Creating the dedicated welcome flow for spin wheel subscribers in Klaviyo. This included three emails: an immediate discount delivery email, a brand story email sent 24 hours later, and a bestseller showcase email sent 72 hours after signup.

Day 3: Launch and monitoring. The spin wheel went live. The store monitored the first 24 hours closely, watching opt-in rates, prize distribution, and discount code usage. No adjustments were needed as the initial configuration performed as expected.

Day 7: First optimization. After a week of data, the store made one adjustment: they changed the mobile trigger from exit intent to a 30-second time delay. Mobile exit intent detection is less reliable than desktop, and the time-based trigger captured more mobile subscribers.

Day 30: First milestone review. After 30 days, the store reviewed comprehensive performance data and confirmed the spin wheel was generating 4x more daily subscribers than the previous static popup. No further configuration changes were made.

Day 60-90: Scaling and refinement. The store began A/B testing different prize distributions and copy variations. They found that featuring "Up to 25% off" in the pre-spin headline increased the popup engagement rate by 8% compared to the original "Spin for Your Style Reward" headline.

Results & Metrics

The results over the 90-day period were comprehensive and exceeded the store's expectations across every metric they tracked.

Email list growth trajectory. The most dramatic result was the speed of list growth. In the first 30 days, the list grew from 8,200 to 13,800 subscribers. By day 60, it reached 19,400. And by day 90, the list stood at 24,600 subscribers, surpassing their five-year goal in three months. The growth was consistent and sustainable because it was driven by organic traffic and exit-intent timing rather than aggressive interruption tactics.

Opt-in rate improvement. The popup opt-in rate jumped from 2.1% with the old static popup to 12.4% with the spin wheel. This 490% improvement is consistent with industry data showing that gamified popups outperform static popups by 4-6x. The gamification element transformed email signup from a transactional exchange (give email, get discount) into an engaging experience (play a game, win a prize, get a discount).

Revenue impact. Email-attributed revenue increased from $10,200 per month to $26,100 per month by the end of the 90-day period. This increase came from two sources: the larger subscriber base receiving campaigns and flows, and the higher engagement rate of spin wheel subscribers compared to static popup subscribers. Spin wheel subscribers had a 28% open rate on subsequent emails compared to 19% for legacy subscribers, suggesting that the engaging acquisition experience set a positive tone for the ongoing relationship.

Conversion rate improvement. The overall store conversion rate improved from 2.4% to 2.83%, an 18% lift. This was primarily driven by the discount codes generated through the spin wheel. Visitors who received a discount code and returned to use it converted at 8.7%, far above the store average. Even accounting for the margin impact of the discounts, the net revenue generated was strongly positive.

Discount economics. The store carefully tracked the margin impact of spin wheel discounts. The average discount redeemed was 12.8% (weighted by prize probability and redemption rates). However, only 34% of discount codes were redeemed, meaning the effective discount across all subscribers was approximately 4.2%. This modest margin impact was dwarfed by the revenue generated from the expanded email list. For every $1 in discount margin conceded, the store generated $8.40 in incremental revenue.

SMS channel creation. A significant bonus was the creation of an SMS subscriber list from scratch. The 38% dual opt-in rate meant the store gained 6,232 SMS subscribers alongside the email growth. SMS campaigns generated an additional $4,800 per month in revenue by the end of the 90-day period, a channel that did not exist before the spin wheel implementation.

Customer acquisition cost reduction. By converting more first-time visitors into email subscribers who later purchased, the store effectively reduced their blended customer acquisition cost from $32 to $24. Email-acquired customers cost an estimated $3-5 each to convert (the cost of the discount plus the marginal email sending cost), dramatically cheaper than the $32 paid advertising cost.

Seasonal revenue stabilization. Although the 90-day period did not cover a full seasonal cycle, the store observed that email-driven revenue was more consistent week-over-week than advertising-driven revenue. Even during a typically slow February period, email campaigns to the growing list maintained baseline revenue without increasing ad spend.

Key Takeaways

This case study illustrates several principles that apply broadly to Shopify fashion stores looking to accelerate their email list growth and reduce dependence on paid advertising.

1. Gamification dramatically outperforms static popups in fashion. The 490% improvement in opt-in rate was not due to offering a larger discount. The average spin wheel prize was actually comparable to the 10% static popup offer. The difference was entirely in the presentation format. Fashion shoppers, who are already motivated by the excitement of discovery and novelty, respond powerfully to gamified experiences. The spin wheel taps into the same psychological reward mechanisms that make shopping enjoyable in the first place.

2. Exit-intent timing is critical for fashion stores. Showing the popup on exit intent rather than immediately or after a time delay meant the store only presented the spin wheel to visitors who were about to leave anyway. This minimized disruption to the browsing experience while maximizing the chance of capturing an otherwise-lost visitor. For fashion stores where the browsing experience is central to the brand, this timing strategy is essential.

3. The discount economics of spin wheels are favorable. The fear that spin wheel discounts will erode margins is understandable but largely unfounded when properly configured. With a 34% redemption rate and weighted average discount of 12.8%, the effective margin impact was only 4.2% across all subscribers. Meanwhile, the incremental revenue generated produced an 8.4:1 return on discount investment.

4. Dual email and SMS capture multiplies the value of every popup interaction. By adding an optional SMS checkbox, the store essentially doubled the value of their popup real estate. The 38% dual opt-in rate created a new revenue channel with zero additional acquisition effort. Fashion stores should always include SMS as a secondary capture in their popups.

5. Dedicated flows for spin wheel subscribers improve long-term value. Rather than dumping all subscribers into the same welcome series, the store created a spin-wheel-specific Klaviyo flow that acknowledged the prize, reinforced the brand, and transitioned into regular marketing. This intentional onboarding resulted in higher open rates and better long-term engagement compared to generic welcome flows.

6. Speed of implementation removes barriers to testing. The total setup time was under two hours, and the store saw measurable results within the first week. For store owners who are hesitant to invest weeks in a new tool, the rapid implementation and immediate feedback loop of a spin wheel popup make it a low-risk, high-reward experiment.

7. Email list growth compounds over time. The store's email revenue did not just increase proportionally with list size. It grew faster because the larger list enabled more sophisticated segmentation, better A/B testing (more statistical significance), and more revenue from automated flows. The value of each subscriber increased as the total list grew.

8. Brand-consistent design prevents popup fatigue. By investing 30 minutes in customizing the spin wheel to match their brand identity, the store created a popup that felt like a natural part of the shopping experience rather than a generic interruption. Fashion shoppers are particularly sensitive to aesthetic cohesion, and a well-designed popup reinforces brand perception rather than detracting from it.

Frequently Asked Questions

How long does it take to see results from a spin wheel popup?

Most stores see measurable results within the first 7-14 days. In this case study, the fashion store saw a 2x increase in daily email signups within the first two weeks, and reached 3x their original list size within 90 days. The immediate impact comes from the high engagement rate of gamified popups compared to static forms.

What spin wheel prizes work best for fashion stores?

Percentage-based discounts work best for fashion stores. The most effective prize distribution is: 10% off (high probability), 15% off (medium probability), 20% off (low probability), and free shipping (medium probability). Avoid fixed dollar amounts as fashion purchases vary widely in price. The store in this case study found that 15% off was the sweet spot for conversion without excessive margin erosion.

Does a spin wheel popup hurt the shopping experience?

When configured correctly, no. The key is proper timing and targeting. This fashion store triggered the spin wheel on exit intent for new visitors only, meaning it appeared when someone was about to leave anyway. Returning customers and those who had already subscribed never saw it. The store's bounce rate actually decreased by 4% after implementing the spin wheel because it gave leaving visitors a reason to stay.

What email opt-in rate should I expect from a spin wheel?

Fashion stores typically see 10-15% opt-in rates from spin wheel popups, compared to 3-5% from static popups. The store in this case study achieved a 12.4% opt-in rate. Factors that influence opt-in rate include prize attractiveness, popup design matching the store brand, trigger timing, and whether you include SMS opt-in alongside email.

How do you prevent spin wheel subscribers from being low-quality leads?

The concern about discount-only subscribers is valid but manageable. This fashion store addressed it by: requiring email verification before sending the discount code, setting discount codes to expire in 72 hours (creating urgency to purchase), sending a welcome series that established brand value beyond discounts, and gradually reducing discount frequency in email flows. Their spin wheel subscribers had a 34% first-purchase rate within 30 days, proving the leads were high quality.

Can I use a spin wheel popup with Klaviyo or Mailchimp?

Yes. EA Email Popup & Spin Wheel integrates with all major email marketing platforms including Klaviyo, Mailchimp, Omnisend, and others. The store in this case study used Klaviyo and set up automatic tagging so spin wheel subscribers entered a specific welcome flow different from their standard signup flow. This allowed them to nurture discount-acquired subscribers differently.
