Frequently Asked Questions

Common questions about Hosuke for Welcart

Yes. Hosuke is designed to work in conjunction with the Welcart e-Commerce plugin. If Welcart is inactive, a warning is displayed and Hosuke's own hooks are not registered.

By default, the button is auto-injected next to the Welcart sold-out label via the standard usces_filters_single_sku_zaiko_message filter. You can turn auto-injection off in the settings and place the button anywhere via the hosuke_button_html filter or other Welcart hooks.

No. The notify button only appears on SKUs that are currently sold out and do not have "sellable while out of stock" enabled. Even if a shopper somehow registers on an in-stock SKU, the notification only fires at the moment stock transitions from 0 to 1 or more.

Yes. Notifications are managed at the SKU level, not the product level. Each SKU's stock is monitored independently.

Hosuke retries with exponential backoff, up to 3 times (configurable). If the maximum retry count is exceeded, the notification is marked as failed and an alert email is sent to the site administrator.

Yes. Hosuke integrates with the standard WordPress Privacy Tools: Shoppers can request an export of their data via "Tools → Export Personal Data" Shoppers can request erasure via "Tools → Erase Personal Data" Both are keyed by email address. Consent capture at registration time is also configurable (enabled by default).

The "Hosuke → Restock Notifications" admin page has a "Test send" section at the bottom that lets you send any template to any address as a preview.

Hosuke sends all notifications through the standard WordPress wp_mail() function. Whether messages actually reach the inbox depends on your server's mail configuration and the DNS records (SPF/DKIM/DMARC) of your sending domain. Both are outside of Hosuke's control, so Hosuke cannot guarantee or measure deliverability. Small operations may work fine with the default configuration, but if you are sending to Gmail / Outlook / other strict providers, or dozens of messages per day, some may be flagged as spam or silently discarded on the receiving side. Recommended: install a major SMTP plugin (WP Mail SMTP / FluentSMTP / Post SMTP etc.) and connect it to an authenticated sending service (Amazon SES / SendGrid / Mailgun / Postmark / Google Workspace / Microsoft 365 etc.). SMTP plugins transparently intercept wp_mail() calls and re-send via the authenticated route. No changes to Hosuke are required. Publishing proper SPF / DKIM / DMARC records for your sending domain is also the single biggest factor determining Gmail deliverability.

Yes. Logged-in Welcart members can view and manage their notifications at /?hosuke_my_notifications=1. Add a link from the Welcart my-page to this URL (or enable auto-injection in the settings).

Yes. Deactivating the plugin does not delete data. Data deletion is opt-in: only when "Delete all data on uninstall" is enabled in the settings and the plugin is uninstalled will custom tables and options be removed.
