Stamped.io vs Trustmary vs Loox for ecommerce is a comparison for merchants who want to collect customer feedback, publish social proof, and increase conversion with user generated content. This article compares where each tool excels, the trade-offs to expect, and which merchant profile each one suits best.

Why these three are commonly compared

These three products are often evaluated together because they target overlapping parts of the same merchant workflow: gathering customer feedback, turning that feedback into publishable content, and using it to increase trust on product pages and marketing channels. The emphasis differs: Stamped.io combines reviews with lifecycle and loyalty modules, Trustmary focuses on surveys and turning positive responses into testimonials, and Loox focuses on photo and video reviews that drive visual social proof. Each approach targets a specific conversion lever, and the right choice depends on whether you prioritize broad retention features, structured testimonial collection, or visual review marketing.

Stamped.io

Core features and functionality

Stamped.io is a reviews platform built as part of a suite that includes lifecycle messaging and loyalty tools. It supports product reviews, photo and video UGC, in-email review collection, configurable widgets, and survey/NPS-style feedback as part of its review workflows. It also offers lifecycle automation and loyalty program components that integrate with review collection, allowing merchants to coordinate post-purchase journeys and rewards around feedback collection. (website.stamped.io)

Pricing approach

Stamped.io uses a modular pricing approach: individual products such as Reviews, Loyalty, and Lifecycle each have separate plans, and bundles are available. The vendor’s pricing page lists starting prices for single-product plans and higher pricing for multi-product bundles; the Reviews product appears with an entry point around the lower hundreds per month and Lifecycle and Loyalty products have higher listed starting tiers according to the vendor. Describe pricing qualitatively as tiered by product selection and monthly order volume, and consult Stamped’s pricing page for current numbers. (website.stamped.io)

Ease of setup and use

Stamped.io is designed for Shopify merchants, with a no-code install path from the Shopify App Store and prebuilt templates for review emails and widgets. Merchants report being able to get basic review collection live quickly; full use of loyalty and lifecycle modules may require additional configuration and onboarding support. (website.stamped.io)

Integrations

Stamped.io advertises native integrations with Shopify, Klaviyo, Attentive, and common helpdesk/marketing tools. The product is positioned to work inside Shopify ecosystems and with standard marketing/email providers. (website.stamped.io)

Customer support and documentation

Stamped provides an online help center and email/in-app support, and offers onboarding and migration support for larger customers. The vendor’s support pages and billing documentation outline billing practices and plan management. (stampedsupport.stamped.io)

Pros

• Designed to be more than a reviews widget; pairs reviews with lifecycle and loyalty features for retention-focused merchants. (website.stamped.io)
• Photo and video UGC collection integrated into the reviews product.
• Templates and Shopify-focused workflows for faster time to value.

Cons

• Modular pricing means adding lifecycle or loyalty features can materially increase monthly cost, so expect trade-offs between feature consolidation and price.
• Deeper customization or enterprise-level integrations may require managed onboarding.

Best for

Merchants that want reviews plus integrated retention tools, especially Shopify merchants who plan to use loyalty and lifecycle automation alongside review-driven conversion. (website.stamped.io)

Trustmary

Core features and functionality

Trustmary centers on surveys and testimonial capture. It positions itself as a tool to collect NPS and other survey responses, identify promoters, and convert positive responses into publishable testimonials and widgets for the site. It supports multi-channel distribution of survey forms via links, QR codes, embedded widgets, and email. Automated import options from several review sources are supported for bringing existing social proof into the platform. (trustmary.com)

Pricing approach

Trustmary uses tiered limits around views, responses, and requests; the vendor offers a free entry tier and defines metrics such as views (widget loads), responses (survey answers), requests (survey emails sent), and sources (connected social pages). Pricing is therefore usage-based with caps tied to those metrics, rather than a single per-order quota model. Consult Trustmary’s pricing page for exact tiers and limits. (trustmary.com)

Ease of setup and use

Adding Trustmary requires adding a small script to your site, or using a direct embed or link. The vendor emphasizes simple deployment and provides a template library and help center materials to speed setup. Survey distribution options (email, SMS in some regions, QR, links) make it flexible for different collection strategies. (trustmary.com)

Integrations

Trustmary supports importing reviews from Google, Facebook, G2, Capterra, TripAdvisor, and Yelp, and offers integrations with CRMs such as HubSpot and Pipedrive, plus embeddable widgets for any website. The platform focuses on gathering and syndicating testimonial content more than deep ecomm platform hooks. (trustmary.com)

Customer support and documentation

Trustmary provides onboarding materials in a help center, and direct help for customers that need assistance adding the script or configuring widgets. Documentation explains how the view and response quotas work. (trustmary.com)

Pros

• Strong for structured survey capture and turning promoters into testimonials that can be published on site and in widgets.
• Flexible embedding and link/QR workflows make it usable across websites and channels.
• Useful import options for bringing in existing external reviews.

Cons

• Not primarily a product-review system tied to product SKUs; merchants that need product-level review collection and display may find the fit limited.
• Pricing is usage-focused on views/requests rather than orders, so high-traffic sites should plan for view quotas.

Best for

Service providers, B2B merchants, and product merchants that want structured NPS and testimonial capture and who value flexible distribution of testimonial content across channels. (trustmary.com)

Loox

Core features and functionality

Loox is focused on visual product reviews, emphasizing photo and video review collection, attractive on-site widgets, referral incentives, and social proof features such as snippets and carousels. Its tools center on post-purchase review requests, automated reminder emails, and display options optimized for Shopify storefronts. The product includes AI-assisted features for highlighting review stories and reply features. (loox.app)

Pricing approach

Loox uses tiered plans based on monthly orders or usage. The vendor lists a free starter tier and paid plans that start around standard low-double-digit monthly amounts for mid-tier plans, with higher plans for larger stores and an enterprise usage option with capped charges. Pricing is presented as starting points on the vendor pricing page and is tied to the number of orders or review-request emails. Pricing should be verified on Loox’s pricing page for the tier that matches your monthly order volume. (loox.app)

Ease of setup and use

Loox is designed to be a no-code solution for Shopify stores, with a one-click app install, customizable widgets, and a review importer. The vendor emphasizes quick setup and round-the-clock support. Many merchants can collect visual reviews with minimal development work. (loox.app)

Integrations

Loox integrates with Shopify, Klaviyo and Omnisend for review triggers, Google Shopping, Meta Shops for syndication, and common ecomm tools. The vendor provides webhooks and API access on higher plans. Integration coverage is oriented toward Shopify marketing and ad channels. (loox.app)

Customer support and documentation

Loox provides an extensive help center, live support channels, and implementation guidance, with claims of 24/7 support and a knowledge base covering quota mechanics and plan limits. For merchants with very high email/request volumes, Loox documents its monthly quota behavior and pricing mechanics. (loox.app)

Pros

• Strong focus on photo and video reviews, which can raise conversion for visually driven products.
• Shopify-native design and easy setup for non-technical users.
• Features to repurpose visual reviews across email, ads, and social channels.

Cons

• Pricing is tied to order/request volumes; fast-growing stores should monitor quotas to avoid unexpected plan changes.
• Primarily Shopify-centric, so multi-platform or headless stores may need additional work.

Best for

D2C and Shopify merchants selling visually appealing products where photo and video reviews materially influence purchase decisions. (loox.app)

How to pick: a short checklist

• Which content matters most, product-level reviews or testimonial narratives? Choose Loox for visual product reviews, Trustmary for structured testimonial and NPS capture, and Stamped.io when you want reviews integrated with loyalty and lifecycle flows.
• Where will you publish reviews? If you need broad ad/Google/Meta syndication, prioritize a vendor that lists those integrations.

• How much technical work can you invest? Loox and Stamped.io are Shopify-first and generally faster to install; Trustmary requires a script/embed but is flexible across site platforms.
