Hi,
The emails to the main vendor are sent by HkaShop and not HikaMarket.
The goal of HikaMarket is to manage the vendors and the main vendor is the store itself, so it is managed by the HikaShop emails like the "order status notification" sent by HikaShop.
So if you do not receive any email for the main vendor, it means that you unpublished the "order status notification" for HikaShop.

By the way, do not send me private message, use the "contact us" form instead.
