Stamped

Stamped is a software platform that helps online stores collect customer reviews and run loyalty programs. It has two linked jobs. First, it gathers ratings, written reviews, photos, and other user-generated content after a purchase, then displays that social proof on product pages, in search results, and in ads. Second, it runs a loyalty and rewards engine — points for purchases, referrals, and repeat visits — that gives customers a reason to come back. It is most closely associated with Shopify, where it is a widely used app, though it works across other e-commerce platforms too. The core premise is that two of the biggest levers on e-commerce revenue — trust from reviews and repeat buying from loyalty — are related problems, so handling them in one system lets a brand turn a first purchase into ongoing social proof and repeat sales.

Stamped matters because online shoppers rely heavily on other shoppers. A product page with genuine ratings and reviews converts better than a bare one, because reviews reduce the uncertainty of buying something you cannot touch. Collecting those reviews reliably is harder than it looks — it depends on well-timed, low-friction requests — which is the collection problem Stamped is built to solve. The loyalty side attacks a different number: how often existing customers come back. Acquiring a new customer is expensive, so a rewards program that lifts repeat-purchase rate can move profit more than any single campaign. By putting reviews and loyalty under one roof, Stamped ties the trust that wins the first sale to the incentives that win the next one, which is why it sits in the retention and conversion part of an e-commerce stack rather than the acquisition part.

Stamped's defining feature is that it combines reviews and loyalty, where many competitors specialize in one. On the reviews side, it competes with dedicated apps such as Judge.me, Yotpo, Okendo, and Junip. On the loyalty side, with programs like Smile.io or LoyaltyLion. A pure reviews app may collect and display ratings slightly differently — through email, on-site widgets, or post-purchase flows — and a pure loyalty app may offer deeper tiers or gamification. Stamped's pitch is that running both from one platform keeps the customer data and the two programs connected, so, for example, leaving a review can earn loyalty points, and a brand manages one relationship instead of stitching two tools together. The trade-off is the classic suite-versus-specialist question: integration and simplicity against best-of-breed depth in either function.

For a brand choosing, the honest comparison is about fit, not a universal winner. A store whose main gap is social proof might pick the reviews specialist with the highest collection rates and lightest on-site widgets, since heavy widgets can slow page speed and reviews live or die on collection volume. A store whose main gap is retention might pick the deepest loyalty program. Stamped wins when a brand wants both, values a single connected system, and would otherwise be paying for and reconciling two tools. It is worth noting that any on-site review or loyalty widget adds weight to the page, so a brand should watch load time and only render what earns its keep. The right question is which problem is biggest and whether the combined platform serves it better than two specialists would.

Using Stamped well starts with collection, because reviews you never gather cannot help you. That means sending review requests at the right moment — after the product has arrived and been used, not the instant the order ships — keeping the request frictionless, and using incentives carefully so reviews stay honest and disclosed. It means displaying reviews where they change decisions: on product pages, in rich snippets that can show star ratings in search, and in ads. On the loyalty side, it means designing rewards that actually change behavior — points that are easy to earn and worth redeeming, referral incentives, and tiers that recognize the best customers — and connecting the two, so reviewing, referring, and repeat buying all feed one loyalty relationship. Watching the page-speed impact keeps the widgets from costing what they earn.

The failures are familiar. Brands install the app but never optimize the timing or wording of review requests, so collection is thin and the social proof is weak. They incentivize reviews so aggressively that the reviews look bought and lose credibility, or fail to disclose incentives. They bolt on a loyalty program with rewards no one values, so it adds cost without changing behavior. And they ignore the page-speed cost of stacked widgets, letting slow product pages undo the conversion lift the reviews were meant to give. The discipline is to treat reviews and loyalty as a connected retention system — collect reviews well and honestly, display them where they convert, design rewards people actually want, and keep the on-site footprint light — so the platform earns repeat revenue rather than just occupying space in the stack.

Stamped is an e-commerce reviews, ratings, and loyalty platform, widely used on Shopify, that collects customer reviews and runs rewards programs.
