Running out of stock doesn't have to mean losing sales. PreOrder Now helps you keep things moving by letting customers preorder items before they're back or sign up for back in stock alerts when a product is restocked so you know how much to restock and who to notify first. Capture demand early, plan product drops in advance, and offer partial payments. Track performance with Google Analytics, and keep your store running smoothly, your customers informed, and your revenue coming in.

Go beyond the basics with the Klaviyo marketing app. New stores get a guided setup — sign-up form, welcome email, and abandoned-checkout flow — without leaving Shopify Admin. Unify data from 350+ integrations and boost marketing performance with campaigns, smart segmentation, and automated workflows from Klaviyo’s AI Agents. Over 117k brands use Klaviyo and Shopify to grow faster with personalized emails, SMS, WhatsApp messages, and marketing automation tools that turn browsers into buyers.

Inbox puts an AI-powered sales associate on your storefront. Buyers can ask questions and get help finding the right products from your catalog. When buyers sign in with Shop, your Inbox agent can personalize replies using their preferences and purchase history from across Shopify. Run Inbox with or without the agent. Inbox learns from your catalog, policies, and store content while you control its tone, style, and rules.
