Hi,
HikaShop actually sends 4 emails by default:
- The "order admin notification" to the shop owner after an order is created, before the payment
- The "order creation notification" to the customer after an order is created, before the payment
- The "payment notification" to the shop owner after an order's status changes to "confirmed", after the payment
- The "order status notification" to the customer after an order's status changes to "confirmed", after the payment
You're saying that you only see one of the emails to the merchant and none to the customer, so one out of 4 emails, is that correct ?
Please check if you see the missing emails in the menu Customers>Emails history.
If you do, then it's probably an email sending issue.
Then, please check the status of the orders. Are the orders automatically confirmed after the payment ?
Which payment methods are you using on your website ?
Did you disable some of the emails in the System>Emails menu ?
