Grapevine Post Purchase Survey Review (2026)
Stores that want to know where customers really came from and what they think, without per-response pricing that punishes you for asking.
SCORE
/10
Grapevine Post Purchase Survey is a Shopify-native survey platform running since 2017: post-purchase, NPS, CSAT, attribution, on-site, email, and POS surveys with unlimited responses on every plan. Attribution reporting ties answers to order and AOV data so you see revenue by marketing channel, display rules target surveys by order value, product, country, and customer type, and responses flow to Klaviyo, Shopify Flow, GA4, and Google Sheets, or your own AI assistant via MCP. It holds a 5.0 rating from 187 reviews with the Built for Shopify badge, at $25/month flat with a 14-day trial.

What Grapevine actually does
Grapevine runs surveys wherever your customers are: on the thank-you and order-status pages right after purchase (the moment response rates are highest), on-site, in email, and even on Shopify POS for retail. Survey types cover the full toolkit, post-purchase attribution (‘how did you hear about us?’), NPS, CSAT, market research, and product feedback, with conditional logic, custom styling, and seven languages. Display rules decide who sees what: target by order value, product purchased, country, payment method, or new-versus-returning customer.
The reporting is where it earns the subscription. Attribution responses tie to Shopify order data, so instead of ‘ 40% said TikTok’ you see revenue and average order value by channel, which is what you actually need to reallocate ad spend. Every plan has unlimited responses with no overage fees, so scaling up collection never changes the price. Responses push to Klaviyo (for segmentation), Shopify Flow (for automation), GA4, and Google Sheets, and the MCP integration lets you point your own AI assistant at the response data to dig through open-text answers.

Pros & cons
- Unlimited survey responses on every plan, no overage fees when volume spikes
- Attribution reporting ties answers to order and AOV data: revenue by marketing channel, not just response counts
- Runs post-purchase, on-site, in email, and on Shopify POS, with targeting by order value, product, country, payment method, and customer type
- Integrations where the data is useful: Klaviyo, Shopify Flow, GA4, Google Sheets, plus MCP for querying responses with your own AI
- 5.0 from 187 reviews, Built for Shopify badge, and a track record since August 2017
- Reviewers repeatedly describe fast support and the founder shipping requested features within days
- No permanent free plan on the main listing, $25/month after the 14-day trial
- Needs meaningful order volume to justify the cost; low-traffic stores won’t collect enough responses to act on
- Requests customer data access (names, emails, geolocation), inherent to surveying, but worth knowing
- Post-purchase surveys only capture buyers; understanding non-buyers still needs on-site surveys configured deliberately
- English-first admin (surveys themselves support 7 languages)

Before you spend trial time
- Launch the classic ‘how did you hear about us?’ post-purchase survey first; it has the highest response rate and the most actionable data.
- Check the attribution report after two weeks of responses and compare it against what your ad platforms claim.
- Set a display rule (e.g., first-time customers only) and verify the targeting behaves on test orders.
- If you use Klaviyo, confirm responses land as profile properties you can segment on.
- Try the MCP/AI querying on your open-text responses; it’s the fastest way to mine the ‘anything else?’ answers.
- Estimate responses per month from your order volume; if it’s under a few dozen, reconsider whether the data will be decision-grade.

Closing take
Grapevine is what a category veteran should look like: every survey type in one app, unlimited responses at a flat $25, attribution tied to real revenue data, modern integrations including AI querying via MCP, and nine years of merchants vouching for it at 5.0.
Bottom line: if you spend on more than one marketing channel, the attribution survey alone typically pays for the subscription by exposing which channel actually drives buyers. One of the easiest recommendations in our catalog, just bring enough order volume to feed it.

Frequently asked questions
Why do stores run post-purchase surveys?
Because ad-platform attribution is increasingly blind (iOS privacy, cookie loss), asking buyers directly, ‘how did you hear about us?’, is the most reliable attribution signal left. Grapevine ties those answers to order and AOV data so you see revenue by channel.
What does ‘unlimited responses’ actually mean?
Most survey apps price by response volume, so busy months cost more. Grapevine’s $25/month Complete plan has no response caps and no overage fees, collecting more data never raises the price.
Where can surveys run?
Post-purchase on the thank-you and order-status pages (via Checkout Extensions), on-site, in email, and on Shopify POS for retail locations. Display rules target by order value, product, country, payment method, and new-versus-returning customers.
What integrations does Grapevine have?
Klaviyo (responses as segmentable profile data), Shopify Flow (automation triggers), GA4, Google Sheets, customer accounts, and Shopify POS. There’s also an MCP integration so you can query your survey data with your own AI assistant, such as Claude or ChatGPT.
Is there a free plan?
The main listing shows one Complete plan at $25/month with a 14-day free trial and notes more pricing options. Everything is included: unlimited responses, all survey types, attribution reporting, targeting, and integrations, on any Shopify plan.
How established is Grapevine?
Very: launched August 2017 by Union Works Apps (London), Built for Shopify badge, and a 5.0 rating across 187 reviews with 97% five-star. Recent reviews describe the founder shipping a requested feature within a week.
