Best Post-Purchase Survey Apps for Shopify (2026)
The best post-purchase survey app for Shopify depends on how you plan to use the data. If your team already knows what it needs to ask and wants responses flowing into the tools you use every day, Grapevine is the strongest choice: every survey type, unlimited responses, one flat price. If you need deep attribution modelling and have the people in-house to work it, Fairing and KnoCommerce are built for that. Full comparison below.

The best post-purchase survey apps, compared
Grapevine: best overall for most Shopify brands
Grapevine is a Shopify-native survey app that runs post-purchase, NPS, CSAT, attribution and on-site surveys from one place, with unlimited surveys and unlimited responses on a single flat plan. Collecting more feedback never costs more.
Where it stands apart is what happens to the data. Grapevine is built for teams who already know what they want to capture and want to analyse it in their own platforms rather than pay for someone else's dashboard. Responses push straight into Klaviyo, Shopify Flow, GA4 and Google Sheets, and you can query your survey data with your own AI assistant through the MCP integration. Display rules target surveys by order value, product, country, payment method and customer type. It also runs surveys through Shopify POS, so brands with physical stores capture in-person feedback alongside online orders, which most survey apps do not support at all.
The price is the other thing worth saying plainly. Grapevine is $25 a month, flat, and it stays $25 whether you take 100 orders a month or 100,000. It is built and owned by the four people who run it, with no investors to answer to, which is why the price has never needed to climb with your order volume.
Best for: Shopify teams who know what they need to ask, want every survey type included, and want the data in their own stack.
Pricing: $25 per month, flat, unlimited surveys and responses. 14-day free trial.
Honest limitation: Grapevine is deliberately kept simple and fast. Surveys do not branch, so you cannot ask a different follow-up question based on how someone answered the last one, and there is no benchmarking against aggregate industry data. If you want a tool that models attribution for you rather than handing you clean data to model yourself, look at Fairing or KnoCommerce.
Fairing: best for deep attribution with a team to run it
Fairing is a post-purchase survey platform built specifically for marketing attribution, the "How did you hear about us?" category. It ties responses to order value and lifetime value, so you can see which channels drive revenue rather than clicks, and it surfaces hard-to-track channels like podcast, TV and word of mouth that pixels miss. It is Shopify Plus Certified and well reviewed.
Fairing is venture backed and runs an in-house team of data specialists who advise customers on survey strategy and question design. If you have the budget for that and a team internally who will act on deep attribution analysis, it is a serious tool and a fair choice.
Best for: brands whose central problem is attribution modelling, with people in-house to action the findings.
Pricing: tiered by order volume, so the cost rises as you grow.
Honest limitation: it is focused on attribution rather than a full survey toolkit, and because pricing scales with order volume, the bill grows with your store.
KnoCommerce: best for advanced segmentation
KnoCommerce is built for attribution and customer insight with real depth. Its standout is segmentation: responses can be broken across 60+ Shopify attributes such as AOV, products purchased, order count and tags, with conditional logic, a large template library and benchmarking against aggregate response data.
Like Fairing, KnoCommerce is venture backed with data specialists on hand. That support is genuinely useful if you are building a complex, multi-attribute survey programme and want a second opinion on how to structure it.
Best for: mid-market and scaling brands that want deep, segmentable attribution and have the team to use it.
Pricing: tiered, starting around $19 per month and rising steeply for the analyst and pro plans.
Honest limitation: the depth is the point, and it demands a team that will actually work the data. There is no permanently free plan, and the segmentation is wasted if nobody is analysing it.
Zigpoll: best for the widest range of features
Zigpoll has the broadest feature surface of any app in this group: the widest variety of question types, survey formats and delivery channels, spanning on-site, email and SMS, with multilingual support and AI analysis of open-text responses. It carries the highest review volume on the Shopify App Store.
The honest summary is this: if there is something you want to do that Grapevine does not do, Zigpoll probably does it. If your requirement is an unusual question format or a survey type nobody else offers, start there.
Best for: brands with a specific or unusual survey requirement that other apps do not cover.
Pricing: a free tier to start, then volume-based plans.
Honest limitation: the feature breadth comes with more to configure, and pricing scales with response volume, so a high-traffic store collecting a lot of feedback pays for the privilege.
Okendo: best bundled with reviews and loyalty
Okendo Surveys sits inside Okendo's wider customer-marketing suite alongside Reviews, Loyalty, Referrals and Quizzes. Its real advantage is unification: survey responses attach to the same customer profile as reviews and loyalty data, and that combined profile can build audiences directly in Klaviyo and Attentive.
Best for: brands already standardised on Okendo who want surveys unified with the rest of their customer data.
Pricing: an add-on within a suite priced on order-based tiers.
Honest limitation: Surveys is a component of a bundle rather than a focused standalone tool, so it makes most sense if you are buying the suite anyway.
Delighted: closed
Delighted was a Qualtrics-owned NPS, CSAT and CES tool with a Shopify integration. It has now shut down. Customer access ended on 30 June 2026 and all customer data was deleted, so it is not an option for new adoption, and any brand still running NPS through it needs to have moved.
Grapevine is a common replacement, because Delighted users were typically running NPS and CSAT and want the same thing without enterprise pricing. We wrote a guide to switching: Delighted alternative for Shopify.
How we picked: we assessed each app on survey types supported, Shopify integration depth, where the data can be sent, pricing structure, and verified Shopify App Store ratings. Last updated July 2026.
Disclosure: Grapevine publishes this guide and is one of the tools listed. The picks reflect genuine use-case fit, and we have named the cases where another app is the better choice. Competitor pricing and ratings were checked against live Shopify App Store listings at the time of writing, and pricing changes often, so confirm before you buy.
