Stamped.io vs Trustmary vs Okendo for SaaS companies: this article compares three ecommerce review and NPS tools on the criteria SaaS teams most often care about: core capability, pricing approach, integrations, setup effort, and suitability for SaaS business models. The goal is to clarify trade-offs so product, success, and growth teams can choose the right fit rather than a single "best" vendor.

Stamped.io

Features

Stamped.io positions itself as a combined reviews, lifecycle, and loyalty platform with built-in survey and NPS capabilities, plus tools for photo and video UGC, review widgets, and analytics. It supports review request sequences, Google/marketplace syndication, and APIs/webhooks for custom workflows. (website.stamped.io)

Pricing approach

Stamped uses product-based pricing with plans that scale by monthly order volume and by which product modules you select (Reviews, Loyalty, Lifecycle). The vendor lists product entry prices on its pricing page and advertises the ability to assemble bundles, with single-product plans starting around the Reviews entry tier. Because pricing depends on chosen products and order volume, brands are expected to model costs on Stamped’s pricing page or via a demo. (website.stamped.io)

Ease of setup and use

Stamped targets Shopify merchants and provides Shopify-optimized templates and setup guides, plus a help center and developer documentation for APIs. The vendor states that basic programs can be live quickly using prebuilt templates; more complex loyalty or lifecycle flows will require configuration. Support channels include help center documentation and in-app/email support. (website.stamped.io)

Integrations

Stamped documents direct integrations with Shopify and a range of marketing and support tools including Klaviyo, Attentive, Gorgias, and others. It also offers a developer API and webhooks for custom connections. If your SaaS product depends on an events stream into a customer data platform or email platform, Stamped has standard connectors and dev options. (website.stamped.io)

Pros and cons

• Pros: Modular product set lets teams buy only Reviews, or combine with Loyalty and Lifecycle; strong Shopify-first UX and review syndication options; built-in NPS and analytics. (website.stamped.io)
• Cons: Product breadth means multiple modules and add-ons to evaluate, which can complicate ROI modeling; some advanced features are gated behind specific plan tiers or bundles. (website.stamped.io)

Best for

SaaS companies that sell through Shopify storefronts or that rely on product review syndication and want a single vendor that can also handle loyalty and post-purchase lifecycle emails. Stamped fits teams that want Shopify-native widgets plus the option to add NPS and lifecycle automations without stitching separate vendors.

Trustmary

Features

Trustmary is focused on survey-driven testimonials and NPS workflows, with tools to turn positive survey responses into publishable testimonials, embed review widgets, and run structured NPS/CSAT/feedback surveys. The product emphasizes testimonial pages, video testimonials, and AI-assisted review analysis and publishing. (trustmary.com)

Pricing approach

Trustmary publishes explicit tiers including a free entry option that limits monthly survey responses and widget views, plus paid plans and add-ons that increase response quotas, widget views, translation, premium integrations, and white-labeling. The vendor presents pricing components and several optional add-ons so teams can build a plan to match expected response volumes. Use Trustmary’s pricing page to estimate exact monthly costs for your response and view needs. (trustmary.com)

Ease of setup and use

Trustmary emphasizes turnkey testimonial capture and website embedding via widgets and CMS plugins, and it offers prebuilt templates for testimonial forms and NPS surveys. The product is designed for low-touch setup for common use cases, with optional onboarding packages and premium support if a company needs hands-on help. (trustmary.com)

Integrations

Trustmary offers native integrations with CRMs and marketing tools such as HubSpot and Pipedrive, links to Google Sheets, plus Zapier and Make connectors for broader automation. It also supports importing reviews from platforms like Google, G2, Capterra and connecting reviews to website builders including Shopify and WooCommerce. (trustmary.com)

Pros and cons

• Pros: Strong focus on turning NPS and survey responses into publishable testimonials, flexible response-based pricing, and many connectors for CRM and CMS workflows. Good fit where testimonials drive lead generation or B2B purchase decisions. (trustmary.com)
• Cons: Pricing is response- and view-limited on lower tiers, so high-response volume programs (for large SaaS installed bases) may require higher tiers or add-ons; product is testimonial-first rather than a full reviews+loyalty platform. (trustmary.com)

Best for

SaaS companies that prioritize NPS programs, B2B testimonial collection, and converting qualitative feedback into marketing assets. Trustmary is especially useful where testimonial pages, video testimonials, and CRM-driven NPS workflows matter more than on-site product review widgets.

Okendo

Features

Okendo is a customer marketing platform built around Reviews, Surveys, Quizzes, Referrals, and Loyalty, with feature sets designed for review collection, customer segmentation, and using review data in marketing campaigns. Okendo supports review forms, visual UGC, survey and quiz data capture, and loyalty/referral features that tie into reviews and segmentation. (okendo.io)

Pricing approach

Okendo publishes product-level pricing across order-volume tiers and offers bundle discounts when multiple products are purchased together. The vendor advertises entry-level pricing for individual products and a published loyalty entry tier, enabling brands to model costs without a sales conversation. Exact plan pricing should be confirmed on Okendo’s pricing resources or by speaking to Okendo sales. (okendo.io)

Ease of setup and use

Okendo provides detailed setup documentation and integration guides, with many integration playbooks for common ESPs and CDPs. Its admin UI and help center provide guided flows for connecting to ESPs and building review request sequences; some advanced features such as webhooks or custom API work require developer support. (support.okendo.io)

Integrations

Okendo maintains a broad integration library with Klaviyo, Braze, Iterable, Attentive, Shopify Flow, various analytics and helpdesk tools, and middleware support via webhooks and Zapier. Okendo explicitly documents product-level integrations so teams can see what data each product shares. (support.okendo.io)

Pros and cons

• Pros: Clear published pricing across products and volumes, deep integration coverage for growth stacks, and a platform approach that puts reviews, surveys, and loyalty data into one place for customer marketing. (okendo.io)
• Cons: Platform depth can introduce complexity; some advanced integrations and webhooks are gated to higher product tiers and may require engineering effort. (support.okendo.io)

Best for

SaaS companies that operate an ecommerce storefront (Shopify) or that need a unified customer marketing platform combining reviews, surveys, quizzes, and loyalty with predictable product-level pricing. Okendo fits teams that plan to use review and survey data inside email/SMS/automation platforms.
