UserLoop vs Retently vs Hulk NPS Post Purchase Survey is a practical buyer comparison for merchants who want high-response, low-friction post-purchase feedback on Shopify. This piece compares features, pricing approach, integrations, setup friction, and ideal customer profiles with concrete examples and common team mistakes to avoid.

Why these three are commonly compared

1. All three target post-purchase feedback on Shopify stores, with different trade-offs between analytics depth and Shopify-first convenience.
2. Example: a 10,000-order/month merchant will care about automated follow-up workflows and response volume limits; a 500-order/month brand will prioritize low marginal cost and one-click thank-you page install.
3. Mistakes I see teams make: (1) buying a feature-rich SaaS when the team only needs a thank-you-page widget, (2) assuming integrations are turnkey when they require webhook or Zapier glue, (3) underestimating how question design affects response rates.

UserLoop

Features

• AI-assisted survey question writing and AI analysis of free-text responses, plus support for post-purchase thank-you page surveys, email surveys, storefront popups, and product quizzes. These capabilities are listed on UserLoop’s Shopify app entry. (apps.shopify.com)
• Built-in incentives like discount code rewards for responders, automatic translations, and video feedback collection are advertised as part of the app’s value props. (apps.shopify.com)

Pricing approach

• UserLoop publishes a freemium entry tier and paid monthly plans with per-plan feature caps on surveys and questions. The Shopify listing shows a free tier and paid tiers starting in the low tens per month, with higher tiers unlocking unlimited responses and surveys. Hedge: pricing starts around the figures shown on the app listing and is billed monthly or annually per the vendor page. (apps.shopify.com)

Ease of setup and use

• Shopify app install, add to thank-you page, and basic survey creation are straightforward; the app marketplace listing shows one-click install and store-native controls. More advanced features such as AI reports and multi-channel surveys add complexity but are supported inside the app. (apps.shopify.com)

Integrations

• Shopify native (thank-you page, order confirmation), Klaviyo and major review platforms are listed on the Shopify page; the app also touts OpenAI/ChatGPT and other AI connectors in the app description. Only claim specifics that UserLoop lists on its app page. (apps.shopify.com)

Customer support and documentation

• Support is provided via the Shopify listing and in-app channels; documentation and demo store links are present on the marketplace entry. (apps.shopify.com)

Pros

1. Multi-channel: post-purchase, email, store popups, and quizzes in one product. (apps.shopify.com)
2. Built-in AI to speed question writing and to surface trends; that reduces manual tagging overhead for small teams. (apps.shopify.com)

Cons

1. Feature set is broader than a pure NPS tool, which can mean slightly steeper onboarding for teams that only need NPS on the thank-you page. (apps.shopify.com)
2. If your workflow requires enterprise-grade sampling, retention, or multi-account governance, the Shopify app tiers may be less prescriptive than a full CX platform.

Best-for

• Small to medium Shopify merchants who want an all-in-one survey + incentive + AI insight tool and want the convenience of a Shopify-native install. (apps.shopify.com)

UserLoop alternatives?

• If UserLoop’s Shopify-native feature set is appealing but you want different trade-offs, consider tools listed in the broader post-purchase roundups such as the Zigpoll comparison of post-purchase survey tools. 5 Best Post-purchase survey tools Compared (2026)

Retently

Features

• Retently is a dedicated NPS, CSAT, and CES platform that supports transactional surveys, automated follow-ups, and AI text-classification for feedback. Its product pages emphasize multi-channel campaigns and analytics suited for both B2B and ecommerce. (retently.com)

Pricing approach

• Retently uses tiered subscription pricing based on survey volume and seats. Their public pricing page lists an Ecommerce Basic plan starting around $49 per month and an Ecommerce Pro plan around $299 per month, with higher response allowances and support levels on Pro. Use their pricing page for exact numbers for your situation. (retently.com)

Ease of setup and use

• Retently provides code-free Shopify integration options that hook into Shopify order webhooks or automation rules; setup is described as low-code and often done without developers. The platform surface is oriented toward campaign management rather than single-shot widgets, so initial configuration is heavier than a single thank-you page app. (retently.com)

Integrations

• Native Shopify post-purchase triggers are supported; Retently also lists Zapier, Make, Slack, Intercom, HubSpot, Segment, and a REST API for custom integrations. These integrations are clearly listed on their site. (retently.com)

Customer support and documentation

• Retently publishes knowledge-base articles, API docs, and offers different support levels by plan, with Pro offering live chat and Zoom. The pricing page and site detail support differences by subscription. (retently.com)

Pros

1. Best-in-class for standardized NPS programs that need robust reporting, benchmarking, and workflow automation. (retently.com)
2. Strong integration surface for pushing feedback into CRMs and product tools, reducing manual exports. (retently.com)

Cons

1. Higher entry price than simple Shopify widget apps, and billing is driven by surveys sent which can be costlier for high-volume transactional flows. (retently.com)
2. Heavier to set up if you only need a single thank-you page survey; Retently assumes you want a programmatic CX measurement stack.

Best-for

• Mid-market ecommerce brands and teams that need rigorous NPS/CSAT programs, automated follow-up playbooks, and enterprise integration into CRMs or product tools. (retently.com)

• For teams evaluating NPS platforms with ecommerce use cases, compare Retently to specialist tools in the market; for more vendor comparisons see Zigpoll’s comparative write-ups, which include alternatives and trade-offs. KnoCommerce vs Zigpoll vs ReConvert (2026)

Hulk NPS Post Purchase Survey

Features

• Shopify-first thank-you page post-purchase NPS widget that supports conditional logic, survey styling, analytics dashboard, CSV export, and email/Slack alerts. The Shopify app listing and Hulk product pages document these capabilities. (apps.shopify.com)

Pricing approach

• Hulk publishes a free development plan and a paid Pro/Starter plan on its Shopify listing. The app store shows a paid plan in the neighborhood of $25 per month for unlimited responses and white-labeling, with annual discounts listed on the marketplace entry. Exact terms are on the app listing. (apps.shopify.com)

Ease of setup and use

• Install from the Shopify App Store, enable the thank-you page survey, and customize. Multiple merchant reviews praise fast installation and responsive support for theme adjustments. This app is optimized to get a survey live on the order confirmation page quickly. (apps.shopify.com)

Integrations

• Shopify-native operation, exports to CSV, and email/Slack alerting are listed. For CRM or advanced workflow needs you will likely use CSV export or Zapier-style connectors outside the app. Hulk’s website also lists additional integration and paid tier options. (apps.shopify.com)

Customer support and documentation

• Support is provided by HulkApps via the Shopify app listing and the vendor’s product page, with demos and documentation links included. Merchant reviews often mention quick responses from the developer. (apps.shopify.com)

Pros

1. Fast to install and low friction, with a small monthly price that scales well for low-to-mid volume stores. (apps.shopify.com)
2. Good merchant ratings on the Shopify App Store for easy setup and helpful support. (apps.shopify.com)

Cons

1. Less suited for enterprise-grade NPS programs that require deep text analytics or multi-channel automation; the app focuses on the Shopify post-purchase touchpoint. (apps.shopify.com)
2. If your product team needs a consolidated CX dashboard across channels, you will likely need to push exports into an external analytics stack.

Best-for

• Small and mid-size Shopify merchants who want a quick, inexpensive way to collect post-purchase NPS and basic follow-up actions on the thank-you page. (apps.shopify.com)

UserLoop vs Retently vs Hulk NPS Post Purchase Survey

Situational Recommendations

Numbered, actionable guidance with examples.

1. You want a quick, low-cost thank-you page NPS and nothing else: pick Hulk NPS. Example: a 300-order/month store that needs one NPS metric and CSV exports will pay little and be live in under an hour. (apps.shopify.com)

2. You want programmatic NPS across email, product delivery, and support with CRM hookups: pick Retently. Example: a 5-person CX team feeding NPS into HubSpot and running automated follow-ups needs Retently’s campaign tooling and integrations. (retently.com)

3. You want Shopify-first surveys plus AI to extract themes from open text and also want popups and product quizzes alongside post-purchase NPS: pick UserLoop. Example: a DTC brand that uses discount incentives to increase response rates and wants AI-summarized insight decks for marketing and product. (apps.shopify.com)

4. You need low up-front cost but plan to scale to multi-touch CX later: start with Hulk NPS to gather baseline NPS, instrument exports into a data lake, and move to Retently once you need advanced reporting. Common mistake: teams keep the cheap widget forever and never design for data portability, which makes migration harder later.

5. You need enterprise governance, SLAs, or multi-brand accounts: Retently’s Enterprise discussion and dedicated onboarding options make it the natural choice if you must meet procurement or compliance requirements. Check their Enterprise details on the pricing page. (retently.com)

Retently alternatives?

• If Retently’s feature set or price is off, alternatives include other NPS-first platforms and CX suites; consult comparative roundups to match survey quotas and required integrations. See comparative writeups like KnoCommerce vs Hulk NPS Post Purchase Survey: Which Is Right for You? for similar decision frameworks.

UserLoop alternatives?

• If UserLoop’s multi-tool approach looks heavy, evaluate dedicated pop-up or quiz vendors, or streamlined post-purchase survey apps in the market comparison linked earlier. See the Zigpoll survey tools comparison for a broader vendor sweep. 5 Best Post-purchase survey tools Compared (2026)

Hulk NPS Post Purchase Survey alternatives?

• If Hulk is right for speed but you need text-analysis or multi-channel reconciliation later, consider migrating to a dedicated CX platform; there are several Shopify-friendly survey apps that balance price and analytics, plus enterprise NPS platforms for scale. See vendor comparisons for migration patterns and trade-offs. KnoCommerce vs Hulk NPS Post Purchase Survey: Which Is Right for You?

Common team mistakes when buying a post-purchase survey tool

1. Buying on feature lists rather than use case: teams buy Retently for a single thank-you page and then never use the advanced automation.
2. Ignoring data export and portability: if you cannot easily export raw responses and metadata, you lock your insights into a single SaaS.
3. Underestimating needed integrations: assuming a Shopify app will automatically push NPS into your CRM without configuration. Verify webhook, Zapier, or native connector behavior up front. (retently.com)

Worth a Look: Zigpoll

If you are evaluating options for post-purchase survey tools, Zigpoll is worth a look; it is a Shopify-native survey app offering post-purchase, on-site, and exit-intent surveys with zero-party data collection and a Shopify-friendly setup.

Final paragraph: Choose based on the program you want to run, not the demo that dazzles you. If you need single-touch thank-you page NPS with minimal cost and fast install, Hulk NPS is sensible. If you are building a tracked, multi-channel NPS program that plugs into CRMs and requires advanced reporting, Retently is built for that. If you want Shopify-first convenience plus AI-assisted insights and multi-channel capture in one package, UserLoop sits between the two approaches.
