Stamped vs Reviews.io: Which one fits your store?

Stamped and Reviews.io collect reviews, display widgets, and bill you monthly. On feature charts, they look interchangeable.

The split shows up in two places nobody covers properly: how your customers actually leave the review, and where the star ratings show up after they do.

Stamped bets on getting more reviews into the system. Reviews.io bets on getting them in front of more buyers.

Pick the wrong one for your store and you’ll either pay too much or get less out of the platform than it promises.

Here’s the side-by-side that goes past the pricing table.

The short version

What you’ll actually pay

Stamped charges by monthly orders. Reviews.io charges by review invitations sent. That sounds like a small thing on paper, but it changes which one is cheaper for your store.

Three things the pricing pages don’t say loudly:

• Stamped’s free plan is gone as of 2025. Self-serve Shopify App Store plans still exist but are a feature-locked downgrade you can’t build a real review program on.
• Reviews.io needs 30 days’ written notice to cancel. Annual billing saves 20% but commits you for 12 months. Each top-level domain is a separate subscription, so a .com + .eu brand pays twice.
• Video, SMS, Klaviyo, and AI sit at different tiers on each platform. The headline price almost never matches the bill you end up with.

What collecting reviews actually feels like

This is the part that comparison posts skip, and it’s the part that decides whether your review count grows.

On Stamped: a customer gets an email and can leave a star rating, photo, or video right inside the email. No clicking through, no second screen, no friction. Stamped reports response rates roughly 2x higher than redirect flows, and live-store tests back that up. If review volume is what you care about most, this single feature is the reason to pick Stamped.

On Reviews.io: customers click a link in the email and land on a Reviews. io-hosted page to complete the review. The trade-off is that the invitations connect into your existing Klaviyo, Salesforce, or HubSpot flows more cleanly. If review requests already live inside your marketing automation, Reviews.io plugs into that work rather than running a parallel sequence.

How reviews show up on your store

Both platforms ship widgets for product pages, carousels, badges, and review galleries. The difference is what they prioritize.

Stamped is built for Shopify product pages first. Native widgets feel like part of the theme. Customization is deep on Shopify Plus, and reviews flow into Google Shopping ads from the Business tier upward.

Reviews.io ships a wider widget library (20+ options including grids, sliders, single-review showcases, floating banners) and allows custom CSS on Grow and Plus. Its real edge is Google Seller Ratings: as a Google Licensed Review Partner, star ratings flow into Google Ads automatically from $99/mo without middleware setup. For paid-search-heavy stores, this is what justifies the subscription.

Gut check: organic Shopify product page traffic → Stamped’s display works harder. Google Ads traffic → Reviews.io’s paid-search integration earns its keep.

Day-to-day operations

A review platform you check twice a week is worth more than one you avoid because the dashboard frustrates you.

Dashboards: Stamped’s is dense. Lots of features, occasionally cluttered, with loyalty and lifecycle sections bleeding into the reviews view if you’re on the Full Suite. Reviews.io’s feels like a standalone SaaS tool rather than a Shopify app. Neither is dramatically better; it comes down to what you find faster.

Support: Reviews.io’s support sentiment is consistently strong on G2 (4.8/5 across 600+ reviews, with “fast online customer support” as the most common compliment). Stamped’s is solid but more mixed; slow ticket responses surface in WooCommerce-related reviews specifically.

Reliability: Stamped’s Shopify integration is rock solid. Its WooCommerce integration has known bugs in 2025-2026 G2 reviews, including review sync issues. Reviews.io handles WooCommerce, BigCommerce, Magento, and custom stores more cleanly out of the box.

Migration: Both offer CSV import. Reviews.io’s tooling for importing from Yotpo, Stamped, and Trustpilot is more polished.

Stamped’s hidden cost: Loyalty bundling

One thing the headline pricing won’t show you: Stamped’s real play is bundling Reviews with Loyalty and Lifecycle into a Full Suite that starts around $279/month. If you’d buy a separate loyalty tool anyway (Smile.io, LoyaltyLion, Yotpo Loyalty often run $99-$300/mo), the bundle math gets competitive.

Reviews.io doesn’t sell loyalty at all. You’d buy a separate platform if you needed it. That’s either a feature (best-of-breed stack) or a drag (two vendors to maintain), depending on your team.

For reviews-only buyers, this doesn’t move the decision. For buyers who want a bundled stack, Stamped looks better than its headline price suggests.

Where WiserReview fits in this comparison

Not every store is in the Stamped vs Reviews.io decision.

If you want photo and video reviews on every plan, flat pricing that doesn’t track orders or invitations, or multi-channel collection (SMS, WhatsApp, QR alongside email), WiserReview is a third option worth checking against the two above.

What ships on every plan, including the free one:

• Email, SMS, WhatsApp, and QR code review requests
• Photo and video review collection (no tier gating)
• Smart sequences: first request, photo reminder, follow-up
• AI sentiment tagging, AI spam filter, AI-drafted reply suggestions
• 18+ widget styles: Wall of Love grids, carousels, popups, video walls, product galleries
• Klaviyo, Mailchimp, Brevo, and ActiveCampaign integrations
• Google Business Profile sync (external Google reviews pulled into your dashboard)
• Support for Shopify, WooCommerce, BigCommerce, Wix, Squarespace, Magento, Webflow, and PrestaShop
• One-click migration from Stamped, Reviews.io, Yotpo, Loox, Judge.me, and others

Pricing: free up to 100 reviews/month, then $9/mo flat up to 5,000 reviews. One subscription covers multiple domains. No 30-day cancellation notice.

Where it doesn’t compete: WiserReview doesn’t offer in-email submission (Stamped’s signature), doesn’t carry Google Licensed Partner status (Reviews.io’s paid-search edge), and doesn’t include a loyalty engine. If any of those define your use case, the comparison stays between the bigger two.

Conclusion: Which one should you pick?

Pick Stamped → Shopify store, review volume matters, you’d buy a loyalty tool anyway.

Pick Reviews.io → Non-Shopify platform or $10K+/month Google Ads spend.

Consider WiserReview → Flat pricing, photo + video on day one, multi-channel collection.

Whatever you pick, test before committing past $99/mo. Stamped’s $23 Basic and Reviews.io’s 14-day trial both give you real data on your own store. Use one, run a quarter, then make the call.
