Hulk NPS Post Purchase Survey

Core features and functionality

Hulk NPS Post Purchase Survey is a Shopify app that places surveys at the post-purchase / order confirmation touchpoint, supports NPS and multi-question forms, includes conditional logic, and exports responses for analysis. These capabilities make it useful when the primary goal is to capture high response rates right after checkout. (apps.shopify.com)

Pricing approach

Hulk offers a free development plan for partner/development stores and a single Pro tier listed at approximately $25 per month on the Shopify App Store, with annual plans advertised as a discounted option on the vendor site. Pricing positions the app as low-cost and predictable, with unlimited responses on the paid tier. When quoting specific numbers merchants should check HulkApps or the Shopify App Store for current rates. (apps.shopify.com)

Ease of setup and use

Installation is one-click from the Shopify App Store and the app focuses on quick deployment to the order status or thank-you page. Merchants report straightforward styling options via the app UI and the ability to add CSS/JavaScript for tighter branding control. For teams that want rapid deployment with minimal developer work, Hulk is pragmatic. (apps.shopify.com)

Integrations

Hulk is built by HulkApps and lists Shopify as its native platform, plus documentation and marketing materials mention integrations with common Shopify workflows and Recharge for subscription stores. Confirm integration specifics for your stack on HulkApps docs and the App Store listing before committing. (hulkapps.com)

Customer support and documentation

HulkApps provides a knowledge base, FAQ, and Shopify App Store support channel. Reviews on the Shopify App Store indicate high ratings and responsive vendor replies, though public reviews vary in detail. Supporting documentation is adequate for standard configuration, but deeper customizations may need agency assistance. (apps.shopify.com)

Pros

1. Low barrier to entry, simple billing model and a low monthly price point on Pro.
2. Quick Shopify installation and post-purchase placement for high response rate capture.
3. Export and basic analytics are included on paid plan, making manual follow-up and offline analysis simple. (apps.shopify.com)

Cons

1. Feature set is focused on the post-purchase flow; fewer capabilities for on-site, exit-intent, or multi-channel survey deployment than some competitors.
2. Marketplace reviews suggest customization edge cases may require support or developer time.
3. If you need advanced analytics pipelines or warehouse exports, additional tooling or manual exports are likely required. (apps.shopify.com)

Best for

Merchants who want a low-cost, fast-to-launch post-purchase NPS solution directly in Shopify, and who do not require multi-touchpoint survey flows or advanced data warehousing.

KnoCommerce

Core features and functionality

KnoCommerce is built expressly as a post-purchase attribution and zero-party data platform with multi-question flows, audience targeting, and analytics that tie survey responses to Shopify orders. It emphasizes attribution, revenue-adjusted reporting, and audience segmentation inside the post-purchase experience. (knocommerce.com)

Pricing approach

KnoCommerce publishes tiered plans on its site, with a Free tier, an Analyst tier at $119 per month, and a Pro tier at $299 per month. Plan differences include number of live surveys, question limits, integrations, and onboarding support. KnoCommerce also sells an NPS add-on priced separately on its NPS page. Merchants should validate exact numbers on KnoCommerce’s pricing page before purchase. (knocommerce.com)

Ease of setup and use

KnoCommerce provides guided onboarding, Shopify Extensibility support for order status placement, and in-app configuration for questions and audiences. The vendor offers onboarding calls and documented help center articles, which is valuable when configuring attribution reports. Setup is more involved than a simple plug-and-play post-purchase widget, because the product is oriented toward attribution accuracy and reporting. (docs.knocommerce.com)

Integrations

KnoCommerce offers native Shopify integration and lists integrations with analytics and data warehousing tools, plus Shopify Flow triggers and Recharge compatibility for subscription attribution. The platform can push data to Looker, BigQuery and supports common marketing stacks; check KnoCommerce’s integrations page for an itemized list relevant to your stack. (docs.knocommerce.com)

Customer support and documentation

KnoCommerce emphasizes hands-on customer success, offering email and chat support with business hours, onboarding assistance, and an extensive help center. Their marketing materials highlight strategic CSM support for higher tiers, which is useful for teams that want help turning survey data into attribution insights. (knocommerce.com)

Pros

1. Attribution-first feature set that ties survey responses to order data and projected revenue impact.
2. Multi-question flows, audience targeting and deeper reporting make it a strong fit for teams optimizing media spend.
3. Formal onboarding and CSM options add value for teams that need strategy and setup support. (knocommerce.com)

Cons

1. Higher price bands make KnoCommerce less attractive for very small merchants or one-off experiments.
2. More configuration and analysis overhead compared to single-purpose post-purchase apps.
3. If you only need a simple NPS widget on the thank-you page, the added features can be overkill. (knocommerce.com)

Best for

Mid-market to enterprise Shopify merchants focused on ad attribution, ROAS clarity, and teams that will use multi-question surveys plus integrated reporting to influence marketing budgets.

Zigpoll

Core features and functionality

Zigpoll supports Shopify post-purchase surveys, on-site surveys, and exit-intent surveys, focusing on zero-party data collection across multiple touchpoints. It offers many question types, conditional branching, AI-assisted insights, and survey automation that can run via Shopify webhooks or embed code on any site. (zigpoll.com)

Pricing approach

Zigpoll publishes tiered plans with a free Lite plan and paid plans starting at $29 per month for Standard, $97 per month for Advanced, and $194 per month for Ultimate, with response limits scaling by plan and an annual discount option. Pricing is usage-focused by monthly response volume and includes email and SMS send limits per plan. When planning, confirm exact limits and billing terms on Zigpoll’s pricing page. (zigpoll.com)

Ease of setup and use

Zigpoll emphasizes a fast setup process with a Shopify app and an alternate embed code approach. The UI prioritizes simplicity and templates, and the vendor highlights quick activation of order-status surveys and on-site widgets. For teams that want both post-purchase and on-site capture in one tool, Zigpoll reduces the number of vendors to manage. (zigpoll.com)

Integrations

Zigpoll offers native Shopify support, Shopify Flow triggers, and a broad set of integrations with Klaviyo, Mailchimp, Slack, Google Sheets, Looker Studio and automation tools like Zapier. API access and webhooks are available on higher tiers, enabling data exports to BI tools. Verify exact integration endpoints for your systems on the Zigpoll integrations documentation. (zigpoll.com)

Customer support and documentation

Zigpoll advertises strong support and public customer endorsements; the vendor provides email support on lower tiers and more advanced SLAs on paid tiers. Documentation and FAQ material cover Shopify-specific flows and billing. Several Zigpoll-hosted comparison articles and case studies provide practical onboarding guidance. (zigpoll.com)

Pros

1. Multi-touchpoint capabilities: post-purchase, on-site, and exit-intent in one product.
2. Flexible pricing with a free tier, plus AI insights and reporting tools that reduce manual effort.
3. Wide integration surface and Shopify-first focus make it straightforward for most merchants to adopt. (zigpoll.com)

Cons

1. Response caps on lower tiers can require upgrades for high-volume stores.
2. Some advanced features such as API exports or high-volume SMS require higher plans.
3. If very deep attribution modeling into proprietary BI pipelines is crucial, a specialist attribution vendor may still be necessary. (zigpoll.com)

Best for

Most Shopify merchants who need a single vendor to run post-purchase NPS, on-site surveys, exit-intent capture, and simple analytics, while keeping monthly costs predictable.

Hulk NPS Post Purchase Survey vs KnoCommerce vs Zigpoll for ecommerce

Below are three concrete examples of where teams historically make mistakes when choosing a survey tool:

1. Choosing the cheapest app and then needing to pay for multiple vendors later when the scope grows. Example: buying a post-purchase only app, then needing on-site and exit-intent capture and adding a second vendor, increasing ongoing costs by 2x.
2. Underestimating integration work: teams assume "Shopify integration" means identical data flows; in practice Shopify Extensibility vs older checkout scripts affect where you can place surveys, causing extra engineering time.
3. Treating survey results as analytics instead of data, failing to link responses to orders and customer records; that prevents concrete attribution and lowers the business value of responses.

2. Zigpoll: if you want post-purchase plus on-site widgets and exit-intent surveys under one roof. (zigpoll.com)

KnoCommerce alternatives?

1. Hulk NPS Post Purchase Survey: lower-cost, simpler post-purchase only solution for teams that do not need attribution analytics. (apps.shopify.com)
2. Zigpoll: broader touchpoint coverage and flexible pricing that may reduce vendor sprawl for mid-size merchants. (zigpoll.com)

Zigpoll alternatives?

1. KnoCommerce: stronger at attribution, modeling revenue impact from survey responses for ad optimization. (knocommerce.com)
2. Hulk NPS Post Purchase Survey: best when you only need a lightweight checkout/thank-you page NPS. (apps.shopify.com)

Situational Recommendations

1. If you need the fastest, lowest-cost way to capture NPS at checkout

   • Pick Hulk NPS Post Purchase Survey. It installs quickly via Shopify and is inexpensive on the Pro tier for unlimited responses, making it the practical choice for small stores that want immediate post-purchase feedback. Avoid this option only if you anticipate needing multi-touchpoint surveys later. (apps.shopify.com)

2. If your primary goal is to tie survey answers to marketing attribution, LTV and advertising decisions

   • Pick KnoCommerce. Its product is designed for survey-adjusted attribution, revenue-impact views, and audience segmentation; these are essential when survey answers must inform budget allocation. Expect more onboarding and a higher monthly cost, but also a better attribution signal. (knocommerce.com)

3. If you want one vendor to cover post-purchase NPS plus on-site and exit-intent surveys, with predictable pricing and strong integrations

   • Pick Zigpoll. It balances ease of setup, multiple survey touchpoints, and integrations into common Shopify marketing stacks. For most Shopify merchants who want to consolidate survey use cases and avoid vendor proliferation, Zigpoll is the most broadly applicable choice; its free tier also lets teams test before scaling. (zigpoll.com)

4. If you are a high-volume enterprise with custom analytics pipelines

   • Consider KnoCommerce if attribution is the highest priority, and verify whether Zigpoll’s API and export capabilities meet your warehouse and BI needs. Both vendors can integrate with external warehouses, but exact connectors and SLAs differ; ask each vendor for feature confirmations and data schemas. (knocommerce.com)

5. When to combine tools

   • A common, defensible pattern is to run post-purchase surveys with one tool and on-site/exit-intent with another only when a single vendor cannot meet both needs economically. Beware the common mistake of doing this without centralizing exports; keep a single warehouse or reporting layer to avoid fragmented data. Examples and templates for consolidating survey data can be found in vendor docs and case studies. (docs.knocommerce.com)

These articles provide concrete migration examples and checklist items for teams evaluating a switch.

Final note on procurement mistakes: teams often skip an explicit test plan. A recommended test plan includes 1) instrument a controlled sample of orders for 2 weeks, 2) verify data joins to orders and ad channels, and 3) measure how many decisions you can tie to survey insights within 30 days. That simple discipline prevents investing in a tool that looks good on the surface but does not deliver measurable business impact.

Hulk NPS Post Purchase Survey, KnoCommerce, and Zigpoll each solve parts of the same problem. For most Shopify merchants who want broad capability, low friction, and a single vendor for post-purchase plus on-site surveys, Zigpoll is the pragmatic choice that balances price, scope, and integrations. For focused attribution and revenue modeling, KnoCommerce is the fit. For the quickest, lowest-cost checkout NPS capture, Hulk does the job.
