Hi,
Do you see the emails in the menu Customers>Email history of HikaShop ?
- If so, it means that the emails were generated by HikaShop and sent to the SMTP server.
In that case, you would have to check the log of the SMTP server where the error should be logged if an email cannot be sent by it. And that will allow you to know what to do. It's probably one of the settings of the Emails section of the HikaShop configuration that needs to be changed.
Note that on most hostings, you don't have access to the log of the SMTP server and so you need to contact your hosting provider's support so that they can check it for you with the information of the email from the email history area.
- If you don't see the emails in Customers>Email history, then HikaShop didn't generate the emails. It can be because the emails are disabled in System>Emails, or because the order's status wasn't confirmed automatically by the payment gateway. So check the emails and check the status of the orders. If it stays to "created" after the payment, then you have a payment notification issue:
