Stamped.io vs Growave vs Loox for Shopify stores is a common decision point for merchants who want reviews plus different levels of retention marketing. This article compares the three tools side by side, gives concrete pricing anchors and integration notes, calls out mistakes I have seen teams make, and finishes with situational recommendations you can act on.

Why these three are commonly compared

• Stamped.io, Growave, and Loox are often evaluated together because they overlap on reviews while putting emphasis on different adjacent capabilities: Stamped.io on reviews plus lifecycle and NPS/surveys, Growave on an all-in-one marketing stack that bundles reviews with loyalty and referrals, and Loox on photo and video review collection and display.
• Common procurement errors I see: 1) buying a single app for a single feature without modeling order volume and incremental charges, 2) duplicating capabilities across multiple apps and paying for overlapping functionality, 3) not measuring incremental conversion lift from review widgets and review email timing before iterating.

Stamped.io

Core features and functionality

• Primary focus: ecommerce reviews plus lifecycle and NPS/survey capabilities; functionality spans review collection, photo and video reviews, review display widgets, and post-purchase / automated review request flows. According to Stamped, Reviews, Loyalty, and Lifecycle are offered as modular products you can combine. (stamped.io)

Pricing approach

• Stamped publishes product-level pricing and positions pricing by product bundle; their public pricing page lists plan starting points per product and a multi-product bundle option. Stamped states plans start around $299 per month for a single product and around $499 per month for a multi-product bundle, with enterprise options available via demo. Cite Stamped’s pricing page for exact tiers and terms before purchase. (stamped.io)

Ease of setup and use

• Stamped provides Shopify App Store install paths and migration/import tools; onboarding is available via self-serve or dedicated onboarding for higher tiers. The vendor emphasizes templates and pre-set configurations to get live fast. (stamped.io)
• Mistakes I have seen: teams under-resource theme placement and A B test the widget placement or they accept default email cadence without A B testing open and conversion rates, which reduces review capture.

Integrations

• Stamped advertises native integrations with Shopify and common marketing/CRM tools such as Klaviyo and Gorgias, among others listed on their site. Use their Integration Directory to confirm exact connectors for your stack. (stamped.io)

Customer support and documentation

• Stamped documents billing and onboarding in a Help Center and offers email/in-app support; higher-tier customers receive dedicated onboarding. For detailed billing mechanics see their support pages. (stampedsupport.stamped.io)

Pros

• Good if you need reviews plus additional lifecycle and NPS/survey features from a single vendor.
• Built-in tools for photo and video reviews plus an ecosystem of integrations.

Cons

• Pricing is productized; adding Loyalty or Lifecycle is an additional line item, which requires modeling to compare total cost versus piecing tools together.
• Teams sometimes underestimate the effort to migrate reviews and set up moderation rules; factor migration time and testing into the project plan.

Best for

• Midmarket merchants who want a reviews-first vendor that can expand into loyalty and lifecycle automation with the same provider.

Growave

Core features and functionality

• Growave positions itself as an all-in-one Shopify retention platform that includes loyalty, referrals, wishlists, reviews, and Instagram UGC. The product bundles multiple marketing primitives into one app. (growave.io)

Pricing approach

• Growave lists tiered plans with included monthly order allowances and per-100-order overage charges; entry plan pricing is published and higher tiers increase included orders and features. The public pricing page shows plans that start around $49 per month for an entry plan, with growth and plus tiers at higher price points. The site also documents additional order charges when you exceed included monthly orders. Check Growave’s pricing page for precise numbers and any promotional discounts. (growave.io)

Ease of setup and use

• As an all-in-one, Growave reduces the number of installed apps, which lowers the theme work needed for multiple widgets. The trade-off I have seen: implementing many features at once without a prioritized plan creates execution drag; start with reviews and one loyalty use case and iterate.

Integrations

• Growave advertises Shopify and Shopify POS support, plus at least one marketing integration such as Klaviyo on certain plans. Their pricing and help pages list supported integrations and billing behavior tied to Shopify billing. (growave.io)

Customer support and documentation

• Growave’s site and help center explain billing by order volume and include onboarding resources; they advertise email, live chat, and phone support on higher tiers. (growave.io)

Pros

• Consolidates reviews, loyalty, and referrals, which can reduce app bloat and theme complexity.
• Predictable feature parity across stores when you standardize on one app.

Cons

• Order-based pricing means you must model monthly order volume; teams often forget to include growth scenarios when signing up and get surprised by overage charges.
• All-in-one apps can have trade-offs in feature depth compared to specialized vendors.

Best for

• Stores that want to replace multiple single-purpose apps with a single package, and that can commit to one vendor for several marketing flows.

Loox

Core features and functionality

• Loox is focused on visual social proof, prioritizing photo and video review collection and display, with widgets and review request emails optimized for visual content. The vendor emphasizes conversion lift through visual reviews and has tools to import reviews. (loox.app)

Pricing approach

• Loox publishes tiered pricing with starter and higher cap plans for larger merchants; publicly listed tiers start around $14.99 per month for entry tiers, with mid and top tiers listed at higher monthly prices. Loox is billed through Shopify’s billing system. Review Loox’s pricing page for exact plan inclusions and limits. (loox.app)

Ease of setup and use

• Loox is designed as a no-code solution that merchants can install and configure without developer work. The site states you can add widgets and pages to a Shopify theme without code. This makes Loox a common choice for stores that want to get photo reviews on the product page quickly. (loox.app)
• Mistakes I have seen: teams rely on photo discounts as a long-term review bait without testing whether discounts affect average order value and return rates; always test incentives with a revenue lens.

Integrations

• Loox advertises Shopify and Shopify Plus compatibility, and mentions the ability to import reviews from other apps. Loox lists integrations and an API for custom connections. (loox.app)

Customer support and documentation

• Loox provides a Help Center, Academy video tutorials, and claims around-the-clock support channels. Their pricing page and help center include setup guidance. (loox.app)

Pros

• Best for merchants that prioritize photo and video social proof and want a quick, no-code install.
• Strong design-focused widgets and email templates built around visual reviews.

Cons

• Loox is review-first; if you also need loyalty, referrals, or deep lifecycle automation from the same vendor you will need additional apps or integrations.
• If you run a store where customers rarely share photos, a visual-review-first approach may underperform compared to an email-first text review capture strategy.

Best for

• Small to midmarket Shopify merchants who want visually driven reviews and a low-effort setup.

Situational recommendations

I use three concrete decision paths when advising merchants, and I encourage constructing a simple spreadsheet model with expected monthly orders and feature needs for each scenario.

1. You need reviews plus expansion into lifecycle and NPS, and you prefer a single vendor to reduce integration work

   • Consider Stamped.io: the productized approach lets you start with Reviews and add Loyalty or Lifecycle as your retention program matures. Model the monthly product cost times number of products you plan to enable, plus migration effort and templates. If you need a demo-based enterprise contract, budget time for vendor alignment. (stamped.io)

2. You want to replace several point apps (reviews, loyalty, referrals, wishlist) with one consolidated app to lower app count and theme modifications

   • Consider Growave: the bundled offering can reduce app sprawl and centralize loyalty rules and review capture; build a three-year cost projection using their included-order bands and per-100-order overage rules and compare to the sum of single-purpose apps you currently use or are considering. Watch for overage math; model growth sensitivity. (growave.io)

3. You prioritize visual social proof and want a low-effort, high-design review experience with quick ROI on product pages

   • Consider Loox: fast install, no-code widget integration, and visual-first review flows make it a pragmatic pick for DTC brands with photogenic products. Track how many reviews include images and run an A B test to measure uplifts in add-to-cart conversion. (loox.app)

4. If price is the leading constraint, build a minimal viable review capture and display flow in a spreadsheet: compare the monthly base cost plus projected overage (or add-on product costs) against expected revenue uplift from a modest conversion increase. Typical mistakes here are omitting overage or multi-product charges from the model.

5. Integration-first: if Klaviyo flows or a helpdesk connector are mandatory, prioritize the vendor that documents those integrations on their site and include that connector in your procurement checklist. Stamped and Growave both list Klaviyo among integrators; verify connector scope and event payloads on the vendor docs. (stamped.io)

Implementation checklist I give product teams

1. Create a spreadsheet with monthly orders, expected review capture rate, revenue per visit, and expected conversion lift from reviews. Run scenarios for 10, 25, and 50 percent growth in order volume.
2. For each vendor, populate: base monthly fee, overage fees, migration costs, developer hours for theme placement, and estimated lift.
3. Pilot on a single product page and measure incremental conversion and average order value for purchases with and without photo reviews.
4. Re-evaluate after 90 days and decide whether to expand functionality or move to a different vendor.

Worth a Look: Zigpoll

If you are evaluating options for customer review platforms, Zigpoll is also worth a look. Zigpoll is a Shopify survey app offering post-purchase, on-site, and exit-intent surveys, focused on zero-party data capture and a Shopify-native setup. It is a lightweight complement to review platforms when you want structured feedback beyond star ratings.
