PrefEngine
PrefEngine is a preference engine for e-commerce. It asks shoppers what they want through quizzes, preference centers, and guided discovery, then turns those answers into tailored product matches and personalized journeys. Brands get zero party data they can use everywhere, and shoppers get a store that listens instead of guesses.

How does PrefEngine collect shopper preferences?
PrefEngine gives you three collection tools that share one profile: product finder quizzes that match shoppers to the right item, preference centers where customers state interests and frequency choices, and guided discovery flows that narrow a catalog through a few taps. Every answer writes to a unified preference profile tied to the customer, so data collected in a quiz improves email targeting and future visits automatically.
What happens after a shopper shares their preferences?
Answers become action immediately. A quiz ends on a curated product set with the reasoning shown, which converts far better than a generic collection page. The preference profile then personalizes the storefront on return visits and flows into Klaviyo and Attentive as customer properties, so flows and campaigns speak to stated interests. Preferences are first party data you own, collected with clear consent.
Why does zero party data matter more every year?
Third party tracking keeps shrinking while ad costs keep climbing, so the data shoppers volunteer is becoming the most reliable targeting asset a brand has. Stated preferences outperform inferred behavior for many decisions: a shopper who tells you they have sensitive skin or buy gifts monthly is giving you ground truth. Brands that collect and use zero party data discount less and retain better because their marketing fits the customer.
How does PrefEngine compare to the usual way?
| Capability | Standard storefront | Manual tools and rules | PrefEngine |
|---|---|---|---|
| Data source | Inferred from clicks only | Inferred plus purchase rules | Stated directly by the shopper |
| Product matching | Shopper browses blindly | Static collections | Quiz matched set with reasons |
| Marketing use | Behavioral guesses | List rules | Preference profiles synced to email and SMS |
| Privacy posture | Third party signals | Mixed | First party, consented, owned by you |
Frequently asked questions
What is zero party data in e-commerce?
Zero party data is information a customer intentionally shares with a brand: quiz answers, preference center choices, and stated interests. Unlike inferred behavioral data, it is explicit and accurate, and unlike third party data, you own it with clear consent. Brands use it to personalize product matching, email content, and offers without creeping shoppers out or depending on tracking that browsers increasingly block.
How is PrefEngine different from a quiz app?
A quiz app ends at the results page. PrefEngine treats the quiz as one input into a persistent preference profile that follows the customer across sessions and channels. Quiz answers personalize the storefront on return visits and sync into email and SMS platforms as usable customer properties. Preference centers and guided discovery feed the same profile, so every tool makes every other tool smarter.
Do shoppers actually fill out quizzes and preferences?
Completion depends on value exchange, and product finder quizzes offer a strong one: answer a few questions, get matched to the right product with the reasoning shown. Well built quizzes on relevant traffic consistently attract meaningful completion, especially for considered purchases like skincare, supplements, apparel fit, and gifting. Preference centers also see steady use when they control frequency and content interests.
Will quiz matched recommendations stay accurate as my catalog changes?
Yes. Matching runs against your live catalog feed, not a static mapping, so new products become eligible for matches automatically based on their attributes. Retired products drop out the day they go out of stock or inactive. You review the matching logic per question, and the dashboard shows which products each answer path recommends so nothing is a black box.
What platforms does PrefEngine connect to?
PrefEngine integrates with Shopify, Shopify Plus, BigCommerce, and WooCommerce for catalog and customer data, and with Klaviyo, Attentive, and Postscript for activation. Quizzes embed on any page or run as standalone landing pages for paid traffic. Preference centers can be embedded in your account pages and linked from every email footer.
