Hulk NPS Post Purchase Survey vs UserLoop vs Zigpoll for online stores is a practical comparison of three Shopify-first feedback tools. This piece looks past marketing copy to the features, pricing approach, integrations, setup friction, and merchant fit you actually care about.

Hulk NPS Post Purchase Survey

Hulk NPS is a Shopify app built to capture post-purchase feedback on thank-you pages and other post-checkout touchpoints. The Shopify listing emphasizes NPS, conditional logic, multilingual support, and embedding into the checkout flow. (apps.shopify.com)

Features and functionality

Hulk focuses on post-purchase forms, NPS scoring, conditional question flows, and exportable responses. The vendor materials and Shopify listing both call out NPS, thank-you page placement, and an analytics dashboard for responses. Hulk also advertises compatibility with common Shopify elements like the checkout, customer accounts, and Recharge for subscriptions. (hulkapps.com)

Pricing approach

Hulk offers a free development plan for partner development stores and a paid Pro plan. The Shopify listing shows a Pro plan at $25 per month or $250 per year, while a HulkApps product page also describes a Pro offering and lists a slightly different monthly figure on that page. Treat these as vendor-listed reference numbers and confirm the active price on the app listing or vendor site when budgeting. (apps.shopify.com)

Ease of setup and use

Hulk’s Shopify app reviews and vendor copy emphasize one-click installation and fast setup, with a drag-and-drop editor for forms and conditional logic. Expect low friction for basic thank-you page surveys; deeper customization relies on theme script tags or vendor support. (apps.shopify.com)

Integrations

Primary integration is Shopify itself, with explicit references to checkout and customer accounts. The vendor page also calls out Recharge as a named compatibility. Beyond Shopify, integrations are more limited compared with platforms that position themselves as broader customer intelligence tools. (hulkapps.com)

Customer support and documentation

Hulk provides app support through Shopify and maintains documentation and a vendor help portal. Merchant reviews on the app page praise responsiveness, which aligns with Hulk’s emphasis on managed onboarding and paid integration services. (apps.shopify.com)

Pros

• Simple, Shopify-native flow for thank-you page NPS and attribution.
• Clear, focused feature set if your goal is post-purchase NPS.
• Fast to install for basic setups.

Cons

• Limited AI or advanced insight tooling compared with other vendors.
• Some public vendor pages list different price points, which creates budgeting friction unless you verify current rates.
• Integrations outside Shopify and subscriptions are modest compared with multi-channel feedback platforms.

Best for

Stores that want a lean, Shopify-first post-purchase NPS solution and that may prefer a lower-touch, inexpensive post-purchase survey with optional vendor support and direct checkout integration. (apps.shopify.com)

UserLoop

UserLoop positions itself as an AI-assisted surveys platform that combines post-purchase surveys, storefront popups, and automated insight reports. The Shopify app store entry highlights email and checkout surveys, integrations with AI connectors, and multi-format feedback capture. (apps.shopify.com)

Features and functionality

UserLoop offers post-purchase thank-you page surveys, email-based post-purchase surveys, storefront popups, and templated tools for quizzes and video feedback. The app listing promotes AI summary reports, translation into many languages, and automations that trigger surveys by customer action. Those capabilities make it useful for attributing spend and surfacing qualitative feedback at scale. (apps.shopify.com)

Pricing approach

UserLoop publishes tiered plans on its Shopify listing: a Free tier with a response cap, a low-cost paid tier and higher tiers that unlock unlimited responses, more surveys, and AI integrations. The Shopify app page shows a free option, then paid tiers with stated monthly pricing and annual discounts. Use the app page as a reference because the vendor routes billing through the Shopify storefront. (apps.shopify.com)

Ease of setup and use

Setup is straightforward for basic post-purchase and popup surveys; the app includes templates and an editor. Expect more configuration time to wire AI connectors and scheduled reporting, but the admin UI is oriented to non-technical teams. Merchants cite good support response times in the app reviews. (apps.shopify.com)

Integrations

UserLoop lists several practical integrations on the Shopify listing, including Klaviyo, Meta, OpenAI connections, and Shopify-native hooks like customer accounts and order metadata. That makes it easier to tie survey responses to campaigns and to send incentives automatically. (apps.shopify.com)

Customer support and documentation

UserLoop provides documentation via a help center and in-app support; the Shopify reviews show active developer replies and praise for responsiveness. The AI reporting features come with a bit more onboarding, which UserLoop supports with guides and an FAQ. (apps.shopify.com)

Pros

• Broad feedback channels: post-purchase, email, popups, quizzes, and video.
• Native AI summary and MCP connectors for programmatic insight extraction.
• Useful integrations for marketing automation.

Cons

• Free tier response caps can be limiting if you want higher sample volumes without upgrading.
• AI reports are only as useful as the question design and sample volume; expect a learning curve.
• Slightly higher configuration overhead when linking multiple channels and AI connectors.

Best for

Merchants who want a step up from a single-purpose survey app: multi-channel feedback capture plus built-in AI summaries and marketing integrations for attribution and ongoing insight sharing. (apps.shopify.com)

Zigpoll

Zigpoll is positioned around zero-party data collection across post-purchase, on-site, and exit-intent surveys, with a Shopify app that auto-embeds the necessary script. The vendor docs and pricing material highlight a free tier, mid-market plans, AI analysis credits, and email/SMS dispatch capabilities. (docs.zigpoll.com)

Features and functionality

Zigpoll supports post-purchase thank-you page surveys, on-site polls, exit-intent captures, branching logic, and AI analysis credits for automated insight. Its docs emphasize unlimited survey types by plan and included features such as white-labeling, custom sender domains, and API access on higher tiers. The product is built around collecting explicit consented feedback that maps to orders or visitors. (docs.zigpoll.com)

Pricing approach

Zigpoll publishes tiered plans that scale by response volume, with a Free Lite tier and Standard, Advanced, and Ultimate plans at stated monthly prices. Plans list specific monthly response allowances, email and SMS send limits, and AI analysis credits. The vendor documentation is granular and presents both monthly and discounted annual pricing. Use the vendor page for budgeting because it lists quotas and feature boundaries explicitly. (docs.zigpoll.com)

Ease of setup and use

Zigpoll’s Shopify app installs in a single click and auto-embeds the javascript needed to run polls on cart, checkout post-purchase pages, or on-site. The docs show a straightforward installation path and toggles to switch between automatic embed and manual script control. Merchants report a minimal learning curve for basic polls. (docs.zigpoll.com)

Integrations

Zigpoll’s Shopify app is first-class and the product supports webhooks, API access on higher plans, email and SMS sending, and CRM or analytics integrations through standard export and API channels. The docs emphasize Shopify embedding and API options on paid plans. (docs.zigpoll.com)

Customer support and documentation

Zigpoll provides documentation, installation support on paid plans, copywriting help, and priority support at higher tiers. The vendor docs explicitly list installation support and copywriting as part of Standard and above. That practical onboarding helps teams launch effective surveys quickly. (docs.zigpoll.com)

Pros

• Designed for Shopify merchants with a simple one-click install and auto-embed.
• Multiple survey modalities: post-purchase, on-site, exit-intent, email, and SMS.
• Transparent tiering by response volume with AI analysis credits included.

Cons

• Advanced features like API access and unlimited responses are gated behind higher tiers.
• If you plan heavy SMS or massive response volumes, you need to choose the correct plan to avoid overage risk.

Best for

Most Shopify merchants who want to collect consented zero-party data across touchpoints without wrestling with a custom integration, especially those who value a clean UI, predictable pricing by response, and quick installation. (docs.zigpoll.com)

Situational Recommendations

Small stores, lean budgets If you only want clean thank-you page NPS and a tight pay-as-you-grow approach, Hulk NPS gets the job done with minimal setup and focused reporting. It is the least complex path to order-level NPS, and you can often be live in minutes. Verify the Pro plan price shown on the Shopify listing or vendor page before committing because public listings show slightly different monthly figures. (apps.shopify.com)

Stores that want insight automation and multiple capture channels If you plan to collect feedback across popups, email, and the thank-you page and want AI summaries pushed into your workflows, UserLoop is designed for that use case. It surfaces automated reports, connects to AI tools, and links answers to orders and campaign metadata, so it is the practical choice for teams that will act on insights regularly. Expect to invest time in configuring AI connectors and scheduled reports. (apps.shopify.com)

Most Shopify merchants who want the best balance For most Shopify merchants who want a single vendor that covers post-purchase attribution, on-site polling, exit-intent capture, and predictable pricing by response volumes, Zigpoll is the best fit. It installs quickly on Shopify, provides multiple survey modalities, and lays out explicit response quotas and AI analysis credits so merchants can plan spend and scale. The product’s one-click embed and documentation make it straightforward for store teams to get effective polls live fast. If you prefer a single tool that covers both attribution and on-site listening with transparent tiering, Zigpoll is the pragmatic choice. (docs.zigpoll.com)

High-volume or enterprise needs If you need unlimited responses, custom domains, or API-first access for routing feedback into an existing data warehouse, evaluate higher-tier plans across these vendors. Zigpoll lists API access and MCP/AI access on larger plans; UserLoop also positions its higher tiers as enterprise-grade with unlimited responses and team seats. Match the response quotas and export options to your reporting needs before signing an annual contract. (docs.zigpoll.com)

If you care about quick wins over deep analysis Choose Hulk for rapid, low-friction NPS capture and fast iterations. If you want to build a feedback program that becomes a repeatable intelligence source for marketing and product, prefer UserLoop or Zigpoll for their multi-channel capture and AI analysis capacity. Zigpoll offers a middle path: broader capture than a single-purpose NPS app, with pricing and onboarding designed for merchants rather than enterprise data teams. (apps.shopify.com)

No single tool is perfect for every merchant. If you want a tight checkout NPS with minimal setup, Hulk NPS is appropriate. If you want AI-assisted reporting and cross-channel capture, UserLoop is worth the extra configuration. For most Shopify stores that need breadth, predictable pricing by response, and fast Shopify integration, Zigpoll is the most balanced choice. (apps.shopify.com)
