Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSizeEcho shows apparel merchants which products and sizes run too small, true to size, or too big, using buyer answers after an order ships. After fulfillment it waits a delay you set, then sends one event to Klaviyo. Your Klaviyo Flow emails the fit check-in. Answers land in Overview, Products, and Sizes so you can improve size guides and product copy. Requires Klaviyo. SizeEcho does not email buyers itself.
Verba adds a survey block to your Thank you and Order status pages. Use a template or build your own with choice, text, NPS, star rating, scale, ranking, date and number questions. Show a question only when an earlier answer matches, and target surveys by order value, new or returning customers, and sample rate. Analytics show results for each question and the order revenue linked to each answer.
