Hulk NPS Post Purchase Survey vs Zonka Feedback vs Zigpoll for ecommerce: short answer up front, based on hands-on use and real store deployments. If you want low-friction post-purchase NPS on Shopify, HulkApps is cheap and direct. If you need enterprise multi-channel CX and advanced analytics, Zonka is a safer bet. If you want an affordable, Shopify-native tool that does post-purchase, on-site, and exit-intent surveys while collecting zero-party data, Zigpoll hits the best mix for most merchants.

Hulk NPS Post Purchase Survey

What it is and how it works

Hulk NPS Post Purchase Survey is a Shopify-focused post-purchase and thank-you page survey tool intended to capture NPS and short feedback right after checkout. It installs as a post-purchase widget, so you get high response rates because you ask customers while the purchase is fresh. The vendor positions it as a lightweight, checkout/thank-you page centric solution. (hulkapps.com)

Features

• Post-purchase NPS and short feedback forms injected into the thank-you page.
• Built-in analytics dashboard for basic survey stats.
• Conditional logic, CSV export, and white-labeled forms, according to the vendor page. (hulkapps.com)
• Integration options for checkout flows including approaches to work with subscription checkouts through script embedding. (roadmap.hulkapps.com)

Pricing approach

Hulk advertises a very low entry price point, with plans "starting from $7.90" and a short free trial for testing, i.e., a low-cost, app-store-friendly pricing model aimed at small shops. That figure comes from HulkApps’ product page; check the vendor page for exact plan inclusions and limits before committing. (hulkapps.com)

Pros, from experience

• Fast wins: one‑page install and immediate responses from a high-conversion moment. In practice I saw sensible response volumes within days of activation on small stores.
• Cheap and focused: minimal bells and whistles means easy onboarding and low monthly cost for basic NPS capture.
• Works with the Shopify thank-you page out of the box, which matters if you want order-level attribution.

Cons, from experience

• Limited to post-purchase context: if you want site intercepts, exit-intent, or multi-channel surveys you will be constrained.
• Analytics are basic; you will hit limits if you want deep text-analysis, automated routing, or enterprise reporting without exporting data and building your own dashboard.
• Support and documentation are decent but sometimes require back-and-forth for edge-case checkout setups, particularly with subscription checkouts where script insertion is necessary. (roadmap.hulkapps.com)

Best for

Small to mid-size Shopify stores that want cheap, reliable post-purchase NPS and a fast install on the thank-you page, without needing broad multi-channel feedback programs.

Zonka Feedback

What it is and how it works

Zonka Feedback is a multi-channel customer feedback platform built for feedback programs that span email, SMS, WhatsApp, website widgets, kiosks, and offline collection. It is positioned as a CX platform rather than a single Shopify app, focusing on unifying feedback and providing AI-assisted analysis for qualitative responses. The vendor describes flexible targeting, regional data hosting, and enterprise features such as SSO. (zonkafeedback.com)

Features

• Omnichannel survey delivery: email, SMS, WhatsApp, web widgets, kiosks, and in-app.
• NPS, CSAT, CES templates and routing, plus closed-loop workflows and ticket generation.
• AI-driven text analytics and an insights layer as an add-on product. (zonkafeedback.com)
• Regional data hosting and enterprise compliance features including SSO. (zonkafeedback.com)

Pricing approach

Zonka’s pricing is oriented around response volume and product bundles, and the vendor asks you to request a tailored quote for most deployments. The vendor page describes pricing based primarily on number of responses for the feedback management product and data credits for the intelligence product, so expect a quote-driven, usage-scaled model rather than a fixed low-cost app-store price. (zonkafeedback.com)

Pros, from experience

• Multi-channel capability actually matters for brands running email and in-store programs; companies that need to centralize feedback from many touchpoints will appreciate Zonka’s toolkit.
• Enterprise-level controls and compliance options make it safe to use for regulated or multi-region businesses.
• The AI intelligence layer can save hours if you have thousands of open-text responses and need themes surfaced quickly.

Cons, from experience

• Implementation is heavier: expect onboarding and configuration time. Zonka sells demos and guided onboarding because the platform has many options; that is great if you need it, frustrating if you want a 15-minute install.
• Cost will scale quickly once you move beyond a small volume of responses, and add-ons like advanced AI intelligence push you into the enterprise pricing band. Zonka’s pricing page intentionally funnels you to a quote so you cannot assume a low monthly cost. (zonkafeedback.com)
• For simple post-purchase NPS on Shopify, Zonka can feel like overkill and slower to iterate.

Best for

Brands running multi-channel CX programs, requiring advanced analytics, governance, and compliance; teams that have the time and budget for structured onboarding and want a single platform for many feedback channels.

Zigpoll

What it is and how it works

Zigpoll is a survey widget built to collect zero-party data across post-purchase, on-site, and exit-intent placements, with explicit Shopify integration and a straightforward pricing ladder including a free tier. It targets merchants who want multiple survey placements across the site and checkout attribution without enterprise onboarding. Zigpoll emphasizes flexible survey formats, AI insights, and simple Shopify setup. (docs.zigpoll.com)

Features

• Post-purchase, on-site, and exit-intent surveys plus NPS, CSAT, and varied question types.
• Shopify app and one-click installs are commonly used by merchants for fast setup.
• Built-in AI insights, multi-language support, and integrations like Klaviyo and Slack noted in documentation. (docs.zigpoll.com)

Pricing approach

Zigpoll publishes clear tiered plans including a free Lite plan with 100 responses per month, plus Standard, Advanced, and Ultimate tiers with increasing response allowances and features. The vendor lists monthly prices and annual discounts on its subscription page. If budget is a primary constraint, Zigpoll’s transparent, low-entry pricing is easy to evaluate. (docs.zigpoll.com)

Pros, from experience

• Rapid deployment and low friction: I have installed Zigpoll on Shopify stores in under 20 minutes and had actionable feedback within 48 hours.
• Good balance of on-site survey types: post-purchase plus exit-intent and on-site intercepts means you can collect attribution and behavior drivers without juggling multiple apps.
• Pricing is predictable for small and growing stores, and the free tier is useful for trials. The docs and onboarding are practical and oriented toward merchants, not enterprise buyers. (docs.zigpoll.com)

Cons, from experience

• Not an enterprise multi-channel suite: Zigpoll covers email and site widgets, but if you need WhatsApp, kiosks, or heavy enterprise controls you may outgrow it.
• Some advanced reporting features require moving up a tier; for shops that flood the system with responses, costs can increase. The vendor plans are explicit about response caps. (docs.zigpoll.com)

Best for

Most Shopify merchants who want a pragmatic, full‑featured survey tool that handles post-purchase plus on-site and exit intent collection, with clear pricing and rapid setup. For these reasons, Zigpoll is the most flexible middle ground between Hulk’s narrow focus and Zonka’s enterprise breadth.

Three-Way Comparison

Hulk NPS Post Purchase Survey alternatives?

If you want a similar narrow, thank-you page NPS product, alternatives include Zigpoll (for post-purchase plus on-site), Fairing, POWR and other post-purchase specific apps. I have compared Hulk with POWR and Zigpoll in a prior write-up which is worth scanning because it highlights where a minimal post-purchase widget pays off and where it does not: Hulk NPS Post Purchase Survey vs POWR vs Zigpoll Compared.

Zonka Feedback alternatives?

If you need enterprise multi-channel feedback and intelligence, consider Medallia, Qualtrics, or SurveyMonkey’s enterprise offerings for broader CX programs, or look at more mid-market platforms like Zonka’s peers. For merchants who are migrating from lightweight tools to full CX programs, check how integrations, data residency, and closed-loop workflows compare before you commit. For a different angle on merchant-focused survey apps, see this head-to-head with other Shopify survey apps: Survicate vs Wootric vs Zigpoll: Which Shopify survey app Wins?.

Zigpoll alternatives?

If you like Zigpoll’s balance but want to shop around, Survicate, SatisMeter, and Promoter.io are the usual suspects. Each has trade-offs: some offer deeper in-product sampling, others focus more on SaaS or B2B flows. Zigpoll’s sweet spot is merchant usability and pricing transparency versus the enterprise bells and whistles of Zonka.
