Grapevine Surveys vs Hulk NPS Post Purchase Survey vs Zigpoll for DTC brands, boiled down: these three Shopify-focused survey tools target the same post-purchase use case but differ in pricing philosophy, scope, and integrations. Read this if you want an objective, operational comparison to pick the right attribution survey tool for a DTC store.

Grapevine Surveys

Features

Grapevine focuses on post-purchase and multi-touch surveys, with an emphasis on attribution and unlimited response volumes. The app highlights post-purchase, email, in-store POS surveys, NPS, and segmentation tools that map responses back to orders and customers for reporting. (apps.shopify.com)

Pricing approach

Grapevine sells a single core plan billed monthly, positioned around unlimited responses for a fixed fee. The Shopify listing shows a flat monthly price and a trial; for exact billing details consult the vendor page. (apps.shopify.com)

Ease of setup and use

Setup is straightforward for merchants who use Shopify flows and want direct Order Status or thank-you page placement. The Shopify listing and merchant reviews point to fast installs and an easy initial deploy on the order status page, which makes Grapevine attractive if you want immediate post-purchase coverage without custom code. (apps.shopify.com)

Integrations

Grapevine advertises native connections into Shopify Flow, Klaviyo, Google Analytics, and Google Sheets, plus compatibility with Shopify POS and the order status page. That tight Shopify integration is useful if your stack already uses those tools. (apps.shopify.com)

Customer support and documentation

Support is provided by the app developer and the Shopify listing references an FAQ and documentation links; review excerpts on the app page emphasize responsive support and quick replies. For deep technical work you will still rely on their docs or support channels. (apps.shopify.com)

Pros and cons

Pros: predictable flat pricing by plan, unlimited responses, direct order-level attribution mapping, and built-in Klaviyo/GA4 hooks. Cons: narrower focus on post-purchase flows compared with multi-channel survey platforms, less emphasis on on-site or exit-intent surveys, and fewer advanced multi-channel automation features than some broader survey suites. (apps.shopify.com)

Best for

DTC brands that need high-volume post-purchase attribution and want a single fixed-cost solution that plugs into Shopify and Klaviyo, especially if you intend to apply surveys to the order status page and tie responses to orders.

Hulk NPS Post Purchase Survey

Features

Hulk NPS is a compact post-purchase NPS and feedback app built to display surveys on thank-you pages, with conditional logic, export to CSV, and basic analytics dashboards. The app emphasizes quick NPS capture and configurable forms for post-purchase engagement. (apps.shopify.com)

Pricing approach

Hulk NPS uses a simple freemium model: a development/test plan and a paid Pro tier. The Shopify listing shows a fixed monthly Pro price that includes unlimited responses for that tier; check the app page for current billing terms. (apps.shopify.com)

Ease of setup and use

Hulk's value proposition is speed and simplicity. Multiple merchants report very fast installs and a short time to live on thank-you pages. The interface is designed for quick NPS deployment; if you plan to run a single-question NPS after checkout, setup friction is minimal. (apps.shopify.com)

Integrations

The app integrates with core Shopify bricks like payment and customer accounts, and lists a few platform partners on its Shopify entry. It is primarily Shopify-native and not positioned as a broad SaaS connector to large martech stacks; for advanced downstream routing you will likely export CSVs or use the developer resources. (apps.shopify.com)

Customer support and documentation

HulkApps generally provides support and documentation linked from the Shopify listing and their site, with active developer responses in reviews. The offering is serviceable for small teams that need guidance during install. (apps.shopify.com)

Pros and cons

Pros: inexpensive, simple to operate, built around NPS which is familiar to many CX teams, and quick to deploy to thank-you pages. Cons: limited scope beyond NPS and post-purchase; fewer built-in integrations for automated journeys than dedicated zero-party data platforms; fewer multi-touch or on-site survey options out of the box. (apps.shopify.com)

Best for

Smaller DTC merchants who want straightforward NPS capture on the thank-you page and do not need broad on-site or email survey programs.

Zigpoll

Features

Zigpoll covers post-purchase attribution, on-site, exit-intent, and NPS with a full question set and AI-assisted analysis. The app highlights zero-party data collection and a focus on tying survey responses to Shopify customer and order dashboards. It also supports SMS and email survey sends and an AI insights layer for response analysis. (apps.shopify.com)

Pricing approach

Zigpoll uses tiered plans, including a free Lite tier and paid plans with increasing monthly response and email/SMS allowances. The vendor lists plan names and approximate response caps and prices on its pricing page, with an annual discount option. Phrase any specific number as approximate and confirm the current plan detail on the vendor site before purchasing. (zigpoll.com)

Ease of setup and use

Zigpoll emphasizes no-code, one-click Shopify integration and an embed script for more custom deployments. Merchants report rapid setup and a clean UI; the app supports multiple survey types without separate installations, which reduces coordination friction when you want both post-purchase and on-site coverage. (apps.shopify.com)

Integrations

Zigpoll advertises direct connections to Shopify, Klaviyo, Mailchimp, ActiveCampaign, Gorgias, Google Analytics, and Zapier-style export paths; the Shopify listing shows a modest but meaningful set of integrations that suit common DTC stacks. If you use Klaviyo or a similar ESP, Zigpoll can push responses into that flow. (apps.shopify.com)

Customer support and documentation

Zigpoll publishes product docs and a pricing/FAQ hub, and the Shopify listing highlights a high rating and many merchant reviews. The vendor leans into service and chat support claims on its site; merchants frequently call out helpful support in reviews. (zigpoll.com)

Pros and cons

Pros: flexible survey placements across the customer journey, explicit zero-party data features, AI-based response aggregation, and a free starter tier that helps sampling. Cons: some advanced enterprise features require higher-priced plans, and if your use case is strictly simple NPS on a thank-you page the feature set is broader than necessary. Those trade-offs are minor for teams that want multi-touch programs. (zigpoll.com)

Best for

Merchants that want a single app to run post-purchase attribution, on-site collection, exit intent intercepts, and email/SMS surveys. For most Shopify-first DTC brands balancing cost and capability, Zigpoll is the most rounded fit.
