Stamped.io vs Eevy AI: Loyalty Programs vs Revenue Per Visitor

If you are evaluating Shopify review apps, Stamped.io and Eevy AI will show up on your shortlist for very different reasons. Stamped positions itself as an all-in-one reviews and loyalty platform. Eevy AI focuses exclusively on making your review displays generate more revenue through automated optimization.

These two apps are solving different problems. Understanding which problem matters more for your store right now is the key to making the right choice.

What Stamped.io Does Well

Stamped has built a broad platform that combines product reviews with loyalty programs, rewards, referrals, and NPS surveys. If you want a single app that handles multiple aspects of customer engagement, Stamped is one of the few options that bundles all of these together.

Reviews and Ratings

Stamped covers the fundamentals of review collection and display. You get automated review request emails after purchase, support for photo and video reviews, a customizable review widget for your product pages, and integration with Google Shopping for rich snippets. The review widget itself is competent — it supports star ratings, filtering by rating, and basic display customization.

The display options are functional but relatively static. You choose a layout, configure the styling, and that is what every visitor sees. There is no testing of different configurations, no data on which layout drives more revenue, and no automatic optimization based on how visitors actually interact with your reviews.

Loyalty and Rewards Programs

This is where Stamped differentiates itself from pure review apps. The loyalty module lets you create points-based reward programs where customers earn points for purchases, reviews, referrals, social follows, and birthdays. Customers can redeem points for discounts, free shipping, or free products.

For stores that want to build a loyalty program without installing a separate app like Smile.io or LoyaltyLion, this bundled approach has real appeal. You get one dashboard, one support team, and one monthly bill instead of juggling multiple apps.

NPS Surveys

Stamped includes Net Promoter Score surveys, which let you gauge overall customer satisfaction beyond individual product reviews. NPS data can help you identify trends in customer sentiment before they show up in public reviews. For brands that track NPS as a KPIs, having it built into the same platform as your reviews saves time.

Referral Programs

The referral module lets you set up give-and-get referral campaigns — for example, "Give your friend $10, get $10 when they purchase." Referral programs can be powerful for acquisition, and having them connected to your loyalty points system creates a unified customer engagement loop.

Stamped's Pricing Structure

Stamped uses a tiered pricing model that gets expensive as you add modules:

Free plan — Basic review functionality with limited features and Stamped branding
Basic ($23/mo) — Reviews with branding removed, photo reviews, Google Shopping integration
Premium ($59/mo) — Adds loyalty points, VIP tiers, and referral programs
Business ($149/mo) — Adds NPS surveys, community Q&A, and advanced integrations
Professional ($299/mo) — Full platform access with priority support

The jump from reviews-only to reviews-plus-loyalty is significant. And at the Premium tier and above, you are paying for the loyalty and rewards infrastructure whether it is driving results or not.

What Eevy AI Does Differently

Eevy AI approaches the review problem from a fundamentally different angle. Instead of bundling reviews with loyalty programs and surveys, Eevy AI focuses on one question: how do you display your existing reviews in the way that generates the most revenue?

Automated A/B Testing with Genetic Algorithms

The core differentiator is automated optimization. Eevy AI continuously tests different review widget configurations against your live traffic — layouts, styling, content ordering, interactive elements, and placement variations. It uses genetic algorithms to evolve toward configurations that maximize revenue per visitor, conversion rate, and average order value.

This is not manual A/B testing where you set up two versions and wait weeks for results. The system runs multiple variations simultaneously, allocates more traffic to better-performing configurations, and continuously introduces new mutations to explore the possibility space. Over time, your review display automatically improves without you touching anything.

Multiple Layout Options

Where most review apps give you one or two layout options, Eevy AI offers carousels, grids, lists, slideshows, shoppable product displays, story-style video bubbles, and more. Each layout type serves a different purpose, and the optimization system can test which format works best for your specific audience.

A carousel might convert better for a fashion brand where visual impact matters. A list might outperform for electronics where customers want to read detailed reviews. The point is that you do not have to guess — the system discovers the answer through real data.

AI Review Summaries

Eevy AI generates concise review summaries that distill the key themes from your product reviews. Instead of making every visitor scroll through dozens of reviews to understand the general sentiment, the summary gives them the highlights immediately. These summaries update automatically as new reviews come in.

Revenue-Focused Metrics

Most review apps track vanity metrics — number of reviews collected, review request open rates, display impressions. Eevy AI tracks what actually matters for your bottom line: revenue per visitor (RPV), conversion rate (CVR), and average order value (AOV). You can see exactly how much additional revenue your optimized review display is generating compared to a static configuration.

The Core Trade-Off: Breadth vs Depth

The fundamental decision between Stamped and Eevy AI comes down to what you need more: a broad customer engagement platform or deep review display optimization.

When Stamped's Breadth Makes Sense

Stamped is a reasonable choice when:

You need a loyalty program and reviews in one app. If you do not already have a loyalty program and want to launch one alongside your reviews, Stamped's bundled approach saves you from managing two separate apps. The convenience factor is real.
You want NPS tracking tied to your review data. If NPS is a metric your team already tracks, having it in the same platform as product reviews creates a more complete picture of customer sentiment.
You are early-stage and want to minimize the number of apps. For new stores trying to keep their tech stack simple, Stamped's all-in-one approach means fewer integrations to manage and fewer monthly invoices.
Referrals are a key growth channel for you. If word-of-mouth is central to your acquisition strategy, having referrals and loyalty in one system creates a flywheel effect.

When Eevy AI's Depth Makes Sense

Eevy AI is the better choice when:

You already have reviews but are not optimizing how they are displayed. If you have 20 or more reviews per product and have never tested different display formats, you are almost certainly leaving money on the table. Eevy AI addresses this directly.
Revenue per visitor is a metric you care about. If your goal is to maximize the revenue impact of every store visit, automated review optimization provides compounding returns that a static display cannot match.
You already have a separate loyalty program. If you use Smile.io, LoyaltyLion, or another dedicated loyalty app, you do not need Stamped's bundled loyalty features. You need the best possible review display, which is what Eevy AI delivers.
You want optimization without manual work. Setting up and maintaining A/B tests manually is time-consuming and requires statistical knowledge. Eevy AI handles this entirely automatically.
You have enough traffic to benefit from testing. Stores with consistent traffic get faster results from automated optimization because the system has more data to learn from.

The Loyalty Program ROI Question

One of the most important questions to ask yourself is whether a loyalty program will actually deliver ROI for your specific store. Loyalty programs work best for stores with high repeat purchase rates — think consumables, skincare, supplements, coffee, pet food. If your customers naturally buy from you every month or two, a points-based program can increase retention and lifetime value.

But if you sell products that people buy once or twice — furniture, electronics, specialty items — a loyalty program may not move the needle. You are paying $59 or more per month for a feature that most of your customers will never engage with.

In contrast, review display optimization benefits every single visitor who sees your reviews, regardless of whether they are a first-time or returning customer. If your review widget converts 8% better because it has been automatically optimized, that improvement applies to 100% of your traffic, all day, every day.

For a store doing $50,000 per month in revenue, a 5% lift in conversion rate from optimized review displays could mean $2,500 in additional monthly revenue. That is a much clearer ROI calculation than hoping your loyalty program drives enough incremental repeat purchases to justify its cost.

Display Quality: Static vs Optimized

This is the area where the difference between the two apps is most stark. Stamped gives you a review widget that looks fine. You configure it once, maybe tweak the colors to match your brand, and it stays the same forever. Every visitor, every device, every product page — they all see the same static widget.

Eevy AI treats your review display as a living system that should constantly improve. The widget that your visitors see today is different from what they saw last month, because the optimization system has discovered better-performing configurations through real testing.

Think about it this way: would you rather have a storefront window that was designed once and never changed, or one that automatically adjusts based on what makes the most people walk in and buy? The product inside is the same — your reviews. The difference is entirely in how they are presented.

Migration Considerations

If you are currently on Stamped and considering a switch to Eevy AI, the process is straightforward. Eevy AI supports importing reviews from other platforms, and your existing reviews transfer with star ratings, text, photos, and customer information intact. The switch does not mean losing your hard-earned review content.

If you want to keep Stamped's loyalty features while upgrading your review display, that is also an option. You could run Stamped for loyalty and rewards while using Eevy AI for review display optimization. This is a more complex setup, but some stores find that the best-of-both approach delivers the highest overall ROI.

The Bottom Line

Stamped.io is a solid choice if you genuinely need a loyalty program and want it bundled with your review functionality. The all-in-one approach has real convenience value, and the loyalty features are well-built.

But if your primary goal is to maximize the revenue impact of your reviews — and especially if you already have a separate loyalty solution or do not need one — Eevy AI is the better investment. The automated optimization approach means your review displays improve continuously without manual effort, and the revenue-focused metrics give you clear visibility into the ROI you are getting.

The question is not which app has more features. It is which features will actually make your store more money. For most Shopify stores, the answer is the one that turns the reviews you already have into more revenue per visitor.
