Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureKlaviyo Reviews collects text, photo, and video reviews with automated email and SMS requests from prebuilt flows. Verified reviews build trust, and AI helps customers write reviews and drafts your replies in your brand voice. Show ratings, summaries, and reviews in on-brand widgets, sync to Google Shopping, and add custom questions.
Most reviews never get a reply. Reviewlark reads the product reviews your store has — from the product metafield or review metaobject your review app writes — and puts them in one inbox with their star rating and text. Set your brand voice once and the AI drafts a reply that sounds like you. Low-rated or sensitive reviews are flagged for a human instead of auto-answered.

- Build segments based on star rating & custom questions
