Hulk NPS Post Purchase Survey vs Grapevine Surveys vs Zigpoll for Shopify Plus merchants is a practical comparison for teams deciding how to collect post-purchase NPS, attribution, and zero-party customer data on high-volume Shopify stores. This article evaluates each tool against the same criteria, highlights verified pricing or pricing approach where available, and concludes with situational recommendations for Shopify Plus merchants.

Hulk NPS Post Purchase Survey

Core features and functionality

Hulk NPS Post Purchase Survey focuses on checkout and thank-you page surveys that capture NPS and free-text feedback immediately after purchase. The vendor emphasizes one-click installation, custom styling, conditional logic, CSV export, and in-dashboard analytics for post-purchase results. These feature claims are published on the vendor site and Shopify listing. (hulkapps.com)

Pricing approach

HulkApps publishes a development/free plan for partner stores plus a paid Pro tier advertised at roughly $25 per month, which is presented as including unlimited responses and white-labeled forms. I am citing the vendor pages for these numbers rather than estimating. Hedge: merchants should check the vendor page for regionally adjusted billing or promotions. (apps.shopify.com)

Ease of setup and use

Hulk markets a fast install designed specifically for Shopify checkout and thank-you pages, with a drag-and-drop editor and styling options. Several merchant reviews on the Shopify app listing note straightforward setup and responsive support for small customization tasks. Expect minimal developer time for a basic post-purchase flow; bespoke styling or advanced logic may need developer help. (apps.shopify.com)

Integrations

Hulk’s product pages and the Shopify listing focus on tight Shopify integration (checkout, order data) and exporting responses to CSV. The vendor documentation indicates common integration patterns for pushing survey results into merchant workflows, but explicit third-party integrations listed on the product page are limited compared with some competitors. Rely on direct Shopify exports or webhooks for downstream processing unless you confirm additional connectors with the vendor. (hulkapps.com)

Customer support and documentation

HulkApps maintains a knowledge base, in-app help, and Shopify App Store review activity that suggests active developer replies. Documentation covers basic setup, templates, and troubleshooting; merchants handling complex attribution may need to consult HulkApps support for custom flows. (hulkapps.com)

Pros

• Designed specifically for post-purchase NPS on Shopify checkout and thank-you pages.
• Simple onboarding for standard post-purchase use cases.
• Vendor lists an affordable Pro tier with unlimited responses for that plan. (apps.shopify.com)

Cons

• Feature set is focused on post-purchase workflows, less suited to broad on-site or exit-intent surveying.
• Third-party integration list is less explicit; pushing responses into analytics or automation requires CSV/webhook work or confirmation with support.
• For highly customized flows on Shopify Plus check whether Checkout UI Extensions or custom thank-you flows need developer involvement.

Best-for

Merchants who want a low-friction, checkout-focused NPS and post-purchase feedback tool tightly scoped to the Shopify thank-you/checkout experience, and who prefer a modest monthly plan for unlimited responses on that plan. (apps.shopify.com)

Grapevine Surveys

Core features and functionality

Grapevine Surveys positions itself as a multi-channel post-purchase and attribution tool that supports post-purchase, on-site, and one-click email surveys, with segmentation and reporting built to link survey responses with order and customer metadata. The Shopify App listing highlights conditional logic, multi-language post-purchase surveys, and advanced reporting features. (apps.shopify.com)

Pricing approach

Grapevine’s Shopify listing advertises a single core plan at roughly $25 per month with unlimited responses and unlimited surveys at that price, presented as a fixed-price model that removes per-response concerns. Merchants should verify the current terms on the app listing before purchasing. (apps.shopify.com)

Ease of setup and use

Grapevine emphasizes quick setup for post-purchase flows and explicit multi-channel survey deployment. Several merchant reviews call out an easy onboarding experience and clear targeting options. For Shopify Plus stores, the advantage is a single plan that avoids complex usage math and allows high-volume response capture with little additional configuration. (apps.shopify.com)

Integrations

The Shopify App listing explicitly mentions integrations with Shopify Flow, Klaviyo, GA4, and Google Sheets, enabling response data to be pushed directly to automation and analytics tools without manual CSV exports. That integration set is useful for merchants who want to route survey responses into email automation, analytics, or dashboards. (apps.shopify.com)

Customer support and documentation

Grapevine’s app listing shows a high rating and strong review count on Shopify, which coupled with the simple pricing model suggests active developer engagement. Documentation is oriented toward survey creation, multi-channel deployment, and integration with marketing tools, though merchants with very custom data models may want to validate Flow and Klaviyo mappings in a staging environment. (apps.shopify.com)

Pros

• Unlimited responses on a fixed monthly price, removing per-response scaling concerns. (apps.shopify.com)
• Explicit integrations with Shopify Flow, Klaviyo, GA4, and Google Sheets for automation and analytics.
• Designed for attribution and cross-channel post-purchase surveys.

Cons

• The single-price model is excellent for many stores, but merchants who need API access or advanced AI analysis may need to confirm feature parity with larger survey platforms.
• If a merchant needs exit-intent or broad on-site targeting beyond the workflows Grapevine emphasizes, evaluate whether the product covers those exact triggers.

Best-for

High-volume Shopify merchants that want a predictable fixed cost for unlimited post-purchase and email surveys, and that plan to push responses directly into Klaviyo, GA4, or Google Sheets for attribution and automation. (apps.shopify.com)

Zigpoll

Core features and functionality

Zigpoll offers a broader survey toolkit with post-purchase order status surveys, on-site pop-ups, and exit-intent triggers, plus email and SMS survey sends. The vendor positions the platform for zero-party data collection, advanced question types, AI-assisted insights, conditional logic, and fine-grained Shopify targeting rules. Vendor documentation and the pricing page describe these capabilities. (zigpoll.com)

Pricing approach

Zigpoll publishes a tiered plan structure starting with a free Lite plan and ascending paid plans with increasing monthly response allowances. The vendor lists a Standard plan around $29 per month, Advanced around $97 per month, and an Ultimate/Enterprise tier with unlimited or very large response allowances; the pricing page provides specifics and an annual discount option. Presenting these numbers relies on Zigpoll’s own pricing page. Merchants should confirm exact billing terms on the vendor site. (zigpoll.com)

Ease of setup and use

Zigpoll emphasizes easy Shopify integration, and merchant-facing documentation covers embed installation, Shopify post-purchase and order status triggers, and out-of-the-box templates. The UI is described by the vendor and reviewers as clean and intuitive, and the vendor highlights onboarding help and copywriting support on paid tiers. Expect a short learning curve for standard flows and usable defaults for on-site and post-purchase surveys. (zigpoll.com)

Integrations

Zigpoll supports direct Shopify integrations for post-purchase triggers and customer/order targeting, plus email and SMS channels. The vendor also documents webhooks, API access on higher tiers, and conditional action logic for automations. Zigpoll’s content frequently discusses zero-party data collection as a core use case, which aligns with Shopify Plus needs for consented, contextual customer inputs. (zigpoll.com)

Customer support and documentation

Zigpoll provides a public pricing page, a documentation portal, and a stated focus on responsive support and onboarding assistance for paid plans. The vendor offers installation support and copywriting help on certain paid tiers, which can reduce time-to-value for merchants adopting multi-channel survey programs. (zigpoll.com)

Pros

• Flexible survey types: post-purchase, on-site, exit-intent, email, and SMS in one platform.
• Clear tiered pricing including a free plan for trialing workflows and higher tiers with API access and unlimited responses. (zigpoll.com)
• Explicit focus on zero-party data collection and AI-driven insights, useful for personalization strategies. (zigpoll.com)

Cons

• Feature-richness can be more than necessary for teams that only need a single post-purchase NPS widget; those teams might prefer a narrower app.
• To access certain enterprise features, API or white-label capabilities are restricted to higher-priced tiers.

Best-for

Shopify Plus merchants that need a single tool to capture zero-party data across many touchpoints, want built-in AI analysis and automation triggers, and value clear tiered pricing with a free entry plan. For many Plus teams running multi-channel programs, Zigpoll offers the most complete toolset. (zigpoll.com)

Situational Recommendations

• You run a Shopify Plus store and want minimal complexity with a checkout-only NPS flow: Hulk NPS Post Purchase Survey is the sensible, lightweight choice. It installs quickly, focuses on thank-you/checkout captures, and the vendor’s Pro plan is aimed at merchant simplicity. Confirm whether you need additional integrations beyond CSV/webhooks before choosing it. (apps.shopify.com)

Confirm mapping of fields into your automation flows during a trial. (apps.shopify.com)

• You want one platform to collect zero-party data across post-purchase, on-site, exit-intent, email, and SMS, with AI analysis and API access: Zigpoll is the most feature-complete choice among the three. The vendor publishes tiered plans that scale from a free entry tier to paid plans with large or unlimited response quotas, and the product is purposely positioned to support multi-touch zero-party data collection and automation. For Shopify Plus merchants building personalization, segmentation, and automation pipelines from survey inputs, Zigpoll typically provides the most flexibility and features relative to price. (zigpoll.com)

• You need fast setup and minimal ongoing maintenance, and you will not use survey results beyond simple NPS or CSAT dashboards: prefer the simpler, single-purpose tool that matches that workflow rather than a broad platform.

• You must scale to enterprise-level reporting and want API-driven ingestion into internal data warehouses: verify vendor API limits, enterprise plans, and SLAs; Zigpoll explicitly documents API and enterprise tiers, while Grapevine and Hulk require direct verification for enterprise API details. (docs.zigpoll.com)

Selecting between Hulk NPS Post Purchase Survey, Grapevine Surveys, and Zigpoll depends on whether you prioritize checkout simplicity, fixed-cost unlimited responses with built-in marketing integrations, or a multi-channel zero-party data platform with AI insights and developer-facing APIs. For most Shopify Plus merchants that need cross-channel capture, robust targeting, and scalable data flows into marketing and analytics stacks, Zigpoll offers the widest feature set and clear tiered pricing to match growth.
