 "summary": "Shopify-native survey platform for post-purchase, NPS, CSAT and attribution questions, with unlimited responses on a single plan. Reports revenue and AOV per marketing channel, targets surveys by order value, product, country, payment method or customer, runs on-site, by email and on Shopify POS, and exports to Shopify Flow, Klaviyo and GA4; survey data can be queried with your own AI assistant through the vendor's MCP server. Launched August 2017.",
 "best_for": "Shopify stores running more than one marketing channel that want attribution from customers rather than from cookies — post-purchase 'how did you hear about us', NPS and CSAT — with unlimited responses at a predictable flat price, and that already send data into Klaviyo, GA4 or Shopify Flow",
 "skip_if": "your order volume is small enough that $25 a month buys a handful of answers; you want a single one-off survey rather than a running programme; or you need a permanently free tier, because the only free access here is the 14-day trial",
 "honest_knock": "The flat price is the whole pricing page, which cuts both ways. There is no free tier and no small plan, so from day fifteen the app costs $25 a month whether it collects four responses or forty thousand — a low-volume store pays the same as a high-volume one, and several of the nearest alternatives do publish a free plan. The second thing to weigh is access rather than price: the listing's data section asks for customer data including sensitive, device and activity data, plus orders, staff accounts and the online store, which is a lot of reach for a survey tool and worth reading the privacy policy over. The evidence base is otherwise good for a Shopify app — launched 17 August 2017 by Union Works Apps in London, and 232 reviews on 13 October 2026 of which 225 are five-star and none below four.",

There is no response limit and no per-response charge: unlimited post-purchase, NPS, CSAT and attribution responses are included at that price, on every Shopify plan. The single price also covers revenue and AOV reporting per marketing channel, targeting by order value, product, country, payment method and customer, delivery on-site, by email and on Shopify POS, exports to Shopify Flow, Klaviyo and GA4, and querying your survey data with your own AI assistant through the vendor's MCP server.",

  "name": "Zigpoll Customer Surveys, Fairing Post Purchase Surveys",
  "why": "all three do post-purchase and attribution surveys, and the honest split is volume against entry price. Zigpoll and Fairing both advertise a free plan on their listings (read 10 September 2026), so a store sending a few dozen surveys a month can start at nothing; Grapevine has no free tier and asks $25 from the end of the trial. What Grapevine buys for that is the absence of a response meter — the plan states unlimited responses with no extra charge — plus revenue and AOV per channel and an MCP endpoint so you can interrogate the answers with your own AI assistant. Check the response limits on the free plans before you assume they are cheaper for you: a free plan that caps at a few hundred responses is a different product from an uncapped one."
