The best post-purchase survey apps, compared
Fairing - best overall for attribution
Fairing is a post-purchase survey platform for Shopify built specifically for marketing attribution, the “How did you hear about us?” category. It ties every response to order value and lifetime value, so you see which channels drive revenue rather than just clicks, and it surfaces hard-to-track channels like podcast, TV, influencer, and word of mouth that pixels miss. It is Shopify Plus Certified, rated 5.0 across 193 reviews, and adds weekly AI attribution insights plus integrations with Klaviyo, Google Sheets, Elevar, and Shopify Flow.
Best for: brands that want to know which marketing actually works, especially those investing in hard-to-measure channels. Pricing: free up to 100 orders per month, then $15 to $199 by volume. Honest limitation: Fairing is focused on attribution, not a full reviews or CX suite, see Okendo for bundled reviews or KnoCommerce for the deepest segmentation.
KnoCommerce - best for deep attribution segmentation
KnoCommerce is a Shopify post-purchase survey platform built for attribution and customer insight. Its standout is depth: you can break responses across 60+ Shopify attributes such as AOV, products purchased, order count, and tags, with 30+ templates, conditional logic, NPS, and HDYHAU, plus benchmarking against aggregate response data and Klaviyo and Shopify Flow integrations.
Best for: mid-market and scaling brands that want deep, segmentable attribution and will pay for it. Pricing: Starter $19, Analyst $119, and Pro $299 per month, with a 7-day trial and no permanently free plan. Rated 4.9 across 116 reviews.
Zigpoll - best low-cost or free to start
Zigpoll is a fast, multilingual Shopify app for post-purchase and on-site surveys covering attribution, NPS, and feedback, with AI-assisted analysis of open-text responses and multi-channel delivery across on-site, email, and SMS. It has the highest review volume in this group, 5.0 across 519 reviews.
Best for: small-to-mid brands that want a polished, low-cost or free-to-start tool. Pricing: a free-forever Lite plan with 100 responses per month, then $39 to $259 by volume. Honest limitation: attribution reporting is lighter on deep Shopify-attribute segmentation than attribution specialists.
Okendo - best bundled with reviews and loyalty
Okendo Surveys is the survey product inside Okendo’s customer-marketing suite of Reviews, Loyalty, Referrals, Quizzes, and Surveys. Its advantage is unification: survey responses attach to the same customer profile as reviews and loyalty data, and that data can build audiences directly in Klaviyo and Attentive. It is a mature, Shopify Plus Certified platform.
Best for: brands already standardizing on Okendo that want attribution and NPS unified with the rest of their customer data. Pricing: platform from $19 per month on order-based tiers, with Surveys as an add-on, so confirm current pricing with Okendo. Honest limitation: Surveys is an add-on within a bundle rather than a focused standalone tool.
Grapevine - best flat-rate unlimited
Grapevine is a Shopify-native survey app that runs post-purchase, NPS, CSAT, and attribution surveys at a single flat price with unlimited surveys and responses. It offers targeting by order value, product, country, payment method, and customer type, plus exports to Klaviyo, Shopify Flow, GA4, and Google Sheets, and is rated 5.0 across 192 reviews.
Best for: cost-conscious brands that want straightforward unlimited surveys at a predictable price, a common Delighted replacement. Pricing: a flat $25 per month, unlimited, with a 14-day trial. Honest limitation: lighter analytics, benchmarking, and AI than attribution specialists.
Delighted - sunsetting in 2026
Delighted is a Qualtrics-owned NPS, CSAT, and CES tool with a Shopify post-delivery survey integration. Important: Delighted is being shut down. Customer access ends June 30, 2026, and renewals have already closed, so it is not a viable new adoption and existing users should plan a migration.
Frequently asked questions
What is a post-purchase survey?
A short survey shown right after checkout that captures zero-party data, like how the customer heard about you, while the purchase is fresh.
What is the best post-purchase survey app for Shopify?
For marketing attribution, Fairing; for deep segmentation, KnoCommerce; for a free or low-cost start, Zigpoll; for flat-rate unlimited surveys, Grapevine; and for surveys bundled with reviews, Okendo.
Are “how did you hear about us” surveys accurate for attribution?
They are directional, self-reported data. They are most powerful when tied to real order and lifetime-value data, as Fairing does, and read alongside your analytics rather than used alone.
Is Delighted still available?
Delighted is sunsetting, with access ending June 30, 2026, so brands are migrating to alternatives.
How much do post-purchase survey apps cost?
From free tiers, including Zigpoll and Fairing up to 100 orders, to a flat $25 per month with Grapevine, to volume-based plans up to about $299 per month.
