Zigpoll: best for flexible surveys across channels
Zigpoll is a survey product for ecommerce and other websites, with post-purchase, on-site, email, and SMS surveys, plus NPS and CSAT questions. It supports Shopify order and status-page surveys, and its published pages also list integrations with marketing tools including Klaviyo, Attentive, and HubSpot. The free Lite plan allows up to 50 responses a month; paid plans start at $39 a month when billed monthly, as of November 2026. (zigpoll.com)
Its strength is breadth: teams can customize questions and delivery, then use built-in reporting or connect answers to other tools. Its Shopify-triggered email and SMS options are Shopify-specific, however, so teams using other commerce systems should check how their order events will reach the survey. (zigpoll.com)
Fairing: best for post-checkout attribution
Fairing focuses on post-purchase surveys, especially “How did you hear about us?” It can put a survey on a Shopify thank-you or order-status page, and its documentation describes deployments on other sites through an embed or Google Tag Manager. Its pricing page lists a free plan for up to 200 monthly transactions and a $49-per-month Core plan for 201-500 transactions, as of November 2026. (apps.shopify.com)
Fairing’s fit is strongest when you want survey answers connected to order data and passed to other tools: its pages list integrations including Klaviyo, Google Sheets, and Shopify Flow. It is more specialized than a general feedback platform, so compare its survey formats and analysis with your needs if the main goal is broad product research rather than attribution. (apps.shopify.com)
Klaviyo: best when the survey belongs in an email flow
Klaviyo is an ESP and customer platform, not just a survey tool. Its post-purchase flows can send review requests, while survey-specific tools such as Fairing are available through its marketplace and can sync responses into Klaviyo for segmentation and follow-up. The published U.S. starting price for its Email plan is $20 per month for 500 active profiles; its free plan is limited to 250 active profiles and 500 emails a month, as of November 2026. (academy.klaviyo.com)
That makes Klaviyo convenient if you already run customer messaging there and want responses to inform future sends. For a flexible, general-purpose post-purchase survey, you will likely need a survey integration; Klaviyo’s native review requests and support CSAT surveys serve narrower purposes. (help.klaviyo.com)
Attentive: best for a short SMS conversation
Attentive can use a post-purchase SMS journey to ask customers for feedback. Its guidance describes waiting at least seven days, branching by product, and collecting replies through a conversational prompt, which suits a quick rating or simple question. Attentive’s pricing page describes usage-based pricing based on factors such as message volume and list size; it does not publish a fixed starting monthly price. (help.attentive.com)
This is a practical option when SMS is already part of your customer communication and you want the interaction to feel like a text conversation. It is less suitable if you need a dedicated survey workspace with broad question types and standalone survey analysis; compare that requirement against a survey-first product before choosing. (help.attentive.com)
Which ESP, CRM, or SaaS martech platform has the best post-purchase survey?
For a dedicated, customizable survey across different sites and channels, consider Zigpoll; for order-linked attribution, consider Fairing. Attentive fits brief SMS feedback inside a messaging journey, while Klaviyo fits teams that want survey or review responses to inform existing flows. (zigpoll.com)
The deciding point is whether the platform itself needs to ask the questions or whether you mainly need it to send the follow-up and act on the answers. A survey-first tool can offer more purpose-built question design and reporting; an ESP or CRM can reduce handoffs when the survey is simple and the response should immediately change a customer segment or message. If your goal is attribution, look for answers tied to an order and exportable to the analytics and marketing systems you use. (zigpoll.com)
What features should I compare in post-purchase survey tools?
Compare trigger and timing controls, survey placement, question types, response limits, and where customer and order data go. Also check branching, mobile presentation, language support, response exports, and whether a survey answer can trigger a follow-up or update a profile. These capabilities matter differently by job: attribution needs a clean channel taxonomy and order matching, while product feedback may need open-text answers, rating scales, and follow-up questions. (zigpoll.com)
Check the pricing unit before comparing entry prices. Zigpoll’s monthly price is plan-based and its free tier is response-limited; Fairing’s plans are based on monthly transaction volume; Klaviyo’s price varies with active profiles; Attentive says pricing depends on use and messaging needs. So compare the cost at your expected order, response, profile, or message volume rather than treating the lowest published figure as a like-for-like quote. (zigpoll.com)
Which platforms make it easiest to send surveys after an order?
A survey on the order confirmation or status page can be easy to ask immediately after checkout; a delayed message can be better when customers need time to receive or try the product. Fairing documents thank-you and order-status-page surveys, while Zigpoll lists Shopify post-purchase surveys and email or SMS triggers from Shopify order events. Attentive supports delayed, product-specific SMS feedback journeys; Klaviyo can send post-purchase review requests through flows, with a separate survey product or integration for broader survey questions. (apps.shopify.com)
If you do not use Shopify, do not assume a Shopify app’s order triggers will work with your store. Check whether the provider supports your commerce platform, can receive order events through an integration or API, or can embed on your confirmation page. For email or SMS, verify that the platform can target the right buyers and time the survey to the purchase, delivery, or product-use moment you care about. (docs.fairing.co)
How should I evaluate survey responses across marketing platforms?
First, match responses to a stable customer or order record, then compare like with like: same question, timing, audience, and answer categories. Track response rate alongside answers, review written comments separately from rating averages, and distinguish what customers say influenced a purchase from what click-based attribution records. Check that a response appears once, reaches the intended platforms, and can be used in the segments or reports you actually need. (fairing.co)
Treat survey attribution as a complementary signal, not a replacement for analytics. Zigpoll’s September 2026 Attribution Index reports that 51.8% of orders across responses from stores using Zigpoll had no tracked source; that figure describes those stores, not the whole market. The practical lesson is to compare customer-stated sources with tracked sources while keeping their definitions and coverage separate. (support.fairing.co)
