The Multi-Vendor add-on enables its own set of email notifications in X-Cart. The store administrator should check and adjust these notifications in the Email Notifications section (Store Setup > Email Notifications). See Quick Guide on Email Notifications for more info.
The notifications of the Multi-Vendor add-on are as follows:
Messages related to the management of vendor accounts:
Vendor account created: This notification is sent when a new vendor account is created.
Vendor account approved: This notification is sent after the store administrator approves a new vendor account.
Vendor account rejected: This notification is sent after the store administrator has denied a new vendor account.
Payout request related messages:
Vendor request for payment: This message is used to notify the administrator when a vendor submits a payout request.
Vendor request has been processed: This message notifies the vendor who has submitted a payout request as to whether the administrator has approved or declined it.
General order-related notifications that you can enable for vendors:
Order canceled: This notification is sent to the vendor when an order gets the "Canceled" status.
Order changed: This message notifies the vendor about the order status update - if no other type of notification is sent.
Order created: This message notifies the vendor of a newly-created order (Disabled by default).
Order declined: This message notifies both the administrator and customer when an order gets the "Declined" status.
Order processed: This notification is sent to the vendor when an order gets the "Paid" status.
Customer has rated the order: This message notifies the vendor when a customer rates their order.
Backordered item in the orders: This message notifies a vendor about the out-of-stock products in a customer's order at the time of order placement (available starting from X-cart 5.4.1.x).
The store administrator should also check the Email Transfer Settings page (Store Setup > Email Notifications) and specify the REPLY-TO email address used for email notifications sent to the vendors. You can do this by adjusting the "Email to use for the REPLY-to field in vendor email" setting.
