In English

Hosuke is an independent restock notification plugin designed specifically for Welcart e-Commerce. , Ltd. and is not officially affiliated with Welcart Inc.

When a shopper visits a product page whose SKU is currently sold out, Hosuke inserts a “Notify me when back in stock” button next to the standard Welcart sold-out label. The shopper enters their email address, and once the SKU’s stock transitions from 0 back to 1 or more, Hosuke automatically dispatches a notification email so the shopper can return to buy. Turns sold-out moments into recovered sales opportunities.

Key features: SKU-level registration (single/multi-SKU), automatic notify-button injection via the standard Welcart filter usces_filters_single_sku_zaiko_message, real-time stock change detection, 15-minute WP-Cron background scan, three customizable email templates (registration confirmation, restock notification, admin alert), [hosuke_restock_list] shortcode and sidebar widget, both guest and Welcart-member registration flows (member email auto-fills), Google reCAPTCHA v3 integration, per-IP rate limiting, send queue with exponential-backoff retry (up to 3 attempts), automatic cleanup of expired notifications, GDPR compliance via WordPress Privacy Tools, one-click unsubscribe, CSV export, WP-CLI command wp hosuke send-queue, and REST API endpoints.

Japanese and English translation files are bundled.
